[0074] The utility model will be described in detail below in combination with the specific implementation manners shown in the drawings. However, these implementation manners do not limit the utility model, and the structural, method or functional changes made by the ordinary skilled in the art based on these implementation manners are all included in the protection scope of the utility model.

[0075] In combination with Figures 1 to 7 , it is a schematic view of the dental assembly 300 of the implementation form of the utility model.

[0076] The dental assembly 300 comprises the functional piece 200 and the dental appliance 100.

[0077] The dental appliance 100 comprises the appliance body 101 with the cavity S and the fixing part 10 protruding the appliance body 101 towards the side away from the cavity S.

[0078] The fixing part 10 has the perforated part 11, and the insertion end 203 of the functional piece 200 is limited in the perforated part 11, so that the mutual connection of the dental appliance 100 and the functional piece 200 can be realized, and the position limitation of the functional piece 200 can be realized by the insertion end 203 being limited in the perforated part 11.

[0079] The dental appliance 100 can be a dental orthodontic appliance, an anchorage nail guide plate, an accessory installation template, etc.

[0080] In one application scenario of the utility model, in combination with Figures 1 to 7 , the dental appliance 100 is taken as the dental orthodontic appliance 100 for example to be described.

[0081] The dental orthodontic appliance 100 can be a clear aligner for example, and the functional piece 200 can be an archwire structure for example, but is not limited thereto.

[0082] The clear aligner can be a shell-shaped structure made of a high polymer material.

[0083] The archwire structure is for example an extraoral arch, a lip bumper, a lower auxiliary arch or an expansion auxiliary arch, etc., such as Figure 1 andFigure 2 As shown, functional component 200 is a lip stop, as... Figure 3 As shown, functional component 200 is an external bow, such as... Figure 4 As shown, functional component 200 is used to lower the auxiliary bow, as... Figure 5 and Figure 6 As shown, functional component 200 is a bow expander / auxiliary bow.

[0084] Figure 1 and Figure 2 The lip guard shown includes an action part 201 corresponding to the anterior tooth area and an archwire 202 connected to both sides of the action part 201 and extending distally. The action part 201 contacts and interacts with the upper lip, and the archwire 202 is connected to two fixing parts 10 of the buccal surface A1 of the dental orthodontic appliance 100.

[0085] Figure 3 The extraoral bow shown includes an archwire 202, which is connected to two fixing parts 10 on the buccal surface A1 of the dental orthodontic appliance 100.

[0086] Figure 4 The depressor bow shown includes an archwire 202, which is connected to two fixing parts 10 on the buccal surface A1 of the dental orthodontic appliance 100, and the middle part of the archwire 202 abuts against the traction buckle 500.

[0087] Figure 5 The bow expander shown includes an archwire 202, which is connected to two fixing parts 10 on the lingual surface A2 of the dental orthodontic appliance 100.

[0088] Figure 6 The bow expander shown includes an archwire 202, the middle of which passes through the fixing part 10 of the lingual surface A2 of the dental orthodontic appliance 100, and the two ends of which pass through the two groove-shaped structures 600 of the lingual surface A2 of the dental orthodontic appliance 100.

[0089] The dental orthodontic appliance 100 includes an appliance body 101 having a cavity S for accommodating teeth, and a fixing part 10 protruding from the appliance body 101 away from the cavity S. That is, the appliance body 101 is the appliance body 101 at this time, and the fixing part 10 is located on the buccal surface A1 or lingual surface A2 of the appliance body 101.

[0090] Taking the functional component 200 as a lip guard as an example, the fixed part 10 is set on the buccal surface A1 of the posterior tooth area. The dental component 300 includes two fixed parts 10 located in the two posterior tooth areas of the same jaw. The functional component 200 includes two insertion ends 203, and the two insertion ends 203 cooperate with the two fixed parts 10 one by one.

[0091] The two archwires 202 of the functional part 201 of the lip bumper extend towards two distal directions on the left and right sides respectively, and the two free ends of the two archwires 202, which are away from the lip bumper, are defined as two insertion ends 203. The entrance of the through-hole part 11 of the fixed part 10 is located on the mesial side of the fixed part 10, and the insertion end 203 enters the through-hole part 11 from the entrance of the through-hole part 11 to realize the connection between the functional part 200 and the orthodontic appliance 100.

[0092] In actual application, when the upper lip interacts with the functional part 201 of the lip bumper, the force is transmitted to the fixed part 10 through the archwires 202, and then the fixed part 10 transmits the force to the orthodontic appliance 100 to realize the distal movement of the molar in the posterior region.

[0093] Of course, in other application scenarios, when the functional part 200 is a non-archwire structure, the insertion end 203 can also not be the free end of the archwire. The insertion end 203 can be other structures, and in addition, the fixed part 10 can also be arranged corresponding to other regions of the teeth (for example Figure 5 、 Figure 6 The fixed part 10 shown is arranged corresponding to the lingual surface A2), and the entrance of the through-hole part 11 can also be located at other positions.

[0094] The insertion end 203 enters the fixed part 10 from the through-hole part 11 to realize the mutual limiting between the insertion end 203 and the fixed part 10, thereby realizing the effective cooperation between the functional part 200 and the orthodontic appliance 100.

[0095] Optionally, in each treatment step, the spatial relative position of the fixed part 10 and the target point remains unchanged.

[0096] The target point refers to a point that does not move in position during the treatment process. For example, the target point is a point on the upper jaw tissue or a point in the anterior region, or the target point is a virtual point in the software design process, such as a point on the CBCT corresponding to the nose, etc.

[0097] In each treatment step, the spatial relative position of the fixed part 10 and the target point remains unchanged, which can ensure that the relative distance between the force application point (corresponding to the target point) and the action point (corresponding to the fixed part 10) remains unchanged, thereby realizing the continuous and stable force application of the functional part 200.

[0098] At this time, the combined part (i.e. the fixed part 10) of the functional part 200 and the orthodontic appliance 100 is moving relative to the teeth to be treated (the teeth in the posterior region).

[0099] Optionally, the free end (i.e. the insertion end 203) of the archwire 202 enters the through-hole 11 from the entrance of the through-hole 11, and the dental assembly 300 further comprises a stop portion 2021 connected to the insertion end 203, the peripheral area of the entrance cooperates with the stop portion 2021 to limit the movement of the archwire 202 towards the inside of the through-hole 11, i.e. to avoid the archwire 202 continuously moving in the distal direction to excessively enter the inside of the through-hole 11, so that the force of the archwire 202 can be more effectively transmitted to the fixed portion 10.

[0100] In addition, at least one U-shaped bending portion 2022 is further formed on the archwire 202, the U-shaped bending portion 2022 is located between the stop portion 2021 and the action portion 201, and the U-shaped bending portion 2022 can be used to adjust the length of the archwire 202 in the mesial-distal direction.

[0101] Optionally, the dental orthodontic appliance 100 further comprises a reinforcing portion 20 arranged adjacent to the fixed portion 10, the reinforcing portion 20 protrudes out of the appliance body 101 towards the side away from the cavity S, and the reinforcing portion 20 is formed with a receiving cavity S2 for accommodating a dental surface accessory, and the height of the reinforcing portion 20 is less than the height of the fixed portion 10.

[0102] Optionally, the accessory can be pre-added on the dental surface, and when the dental orthodontic appliance 100 is worn, the receiving cavity S2 of the reinforcing portion 20 cooperates with the accessory, so that the retention capability between the dental orthodontic appliance 100 and the teeth under stress can be enhanced, and the dental orthodontic appliance 100 is prevented from being removed, and the height of the reinforcing portion 20 is made small to avoid the reinforcing portion 20 excessively interfering with the inside of the oral cavity or the functional part 200.

[0103] Since the functional part 200 exerts force on the fixed portion 10, the area of the appliance body 101 connected to the fixed portion 10 is prone to be separated from the dental surface, and in severe cases, the entire dental orthodontic appliance 100 can be removed, so the reinforcing portion 20 can be arranged adjacent to the fixed portion 10, as shown in Figure 1 and Figure 2 , the reinforcing portion 20 is arranged on the left and right sides and the opposite side of the fixed portion 10.

[0104] In another application scenario of the present application, the dental appliance 100 is taken as an example for description in combination with Figure 8 and Figure 9 .

[0105] The functional part 200 can be, for example, a anchorage pin 200, but is not limited thereto.

[0106] The anchorage pin guide 100 comprises a guide body 1011 having a cavity S for accommodating a tooth and an extension area 1012, the extension area 1012 being an area formed by the extension of the guide body 1011 towards the gingival area A3, that is, the instrument body 101 at this time comprises the guide body 1011 and the extension area 1012 connected together, and the fixing part 10 is located at the extension area 1012, specifically, the fixing part 10 is located at the side of the extension area 1012 away from the gingival area A3.

[0107] The fixing part 10 has a perforated part 11, the insertion end 203 of the anchorage pin 200 is limited in the perforated part 11, the insertion end 203 is an implanting part of the lower end of the anchorage pin 200, and the insertion end 203 is implanted into the gingival area A3 through the perforated part 11.

[0108] The extension direction of the perforated part 11 can be designed according to the required implanting direction of the anchorage pin 200.

[0109] When the insertion end 203 of the anchorage pin 200 enters the perforated part 11, the perforated part 11 can constrain the implanting direction of the anchorage pin 200 so that the anchorage pin 200 is implanted into the gingival area A3 along the extension direction of the perforated part 11, so that the implanting direction of the anchorage pin 200 can be better controlled.

[0110] As shown in Figure 9 The fixing part 10 is part of the extension area 1012, that is, the fixing part 10 is arranged close to the gingival area A3, the perforated part 11 is a through hole at the extension area 1012, the anchorage pin 200 is implanted into the gingival area A3 through the perforated part 11, and the perforated part 11 provides a guiding effect for the implanting of the anchorage pin 200, but is not limited thereto, in order to provide better guiding assistance for the anchorage pin 200, the fixing part 10 can be a structure protruding out of the extension area 1012, and specific implementation forms can be referred to below.

[0111] Optionally, the anchorage pin guide 100 further comprises a reinforcing part 20 arranged adjacent to the fixing part 10, the reinforcing part 20 protrudes out of the extension area 1012 or the guide body 1011 towards the side away from the cavity S, and the reinforcing part 20 is formed with an accommodating cavity S2 for accommodating a dental accessory, and the height of the reinforcing part 20 is less than the height of the fixing part 10.

[0112] Optionally, the reinforcing part 20 is arranged at the area of the guide body 1011, and an accessory can be pre-added on the dental surface, when the anchorage pin guide 100 is worn, the accommodating cavity S2 of the reinforcing part 20 cooperates with the accessory, so that the retention capability between the anchorage pin guide 100 and the tooth under stress can be enhanced, and the anchorage pin guide 100 is prevented from being detached, and the height of the reinforcing part 20 is made small to avoid excessive interference between the reinforcing part 20 and the inside of the oral cavity or the functional part 200.

[0126] In combination with Figure 11 and Figure 12 The schematic view of the cross section of the fixed portion body 12 in the first specific example in the direction perpendicular to the buccal-lingual line and the cooperation with the archwire 202.

[0127] In the first specific example, the through hole portion 11 only includes the first opening hole 111 located on the mesial side surface 1211 of the peripheral portion 121, that is, the other areas of the fixed portion body 12 at this time are closed areas, and the insertion end 203 enters the cavity S1 from the first opening hole 111.

[0128] The dental assembly 300 includes a stop portion 2021 connected to the insertion end 203, and the stop portion 2021 is a bending area of the archwire 202. After the insertion end 203 enters the cavity S1, the stop portion 2021 and the mesial side of the peripheral portion 121 abut each other to limit the length of the archwire 202 entering the cavity S1, and the force acting on the archwire 202 can be transmitted to the fixed portion 10 through the cooperation of the stop portion 2021 and the mesial side surface 1211 of the peripheral portion 121.

[0129] In this specific example, the distance between the center of the first opening hole 111 and the dental surface is 0.8mm-4mm, and the opening size of the first opening hole 111 is less than or equal to half the area of the mesial side surface 1211 of the peripheral portion 121, so as to avoid that the opening size of the first opening hole 111 is too large to lose the support strength of the stop portion 2021.

[0130] In addition, the first opening hole 111 is a circular hole, an elliptical hole or a polygonal hole with chamfer, when the first opening hole 111 is a circular hole, the diameter of the first opening hole 111 is 0.6mm-1.5mm.

[0131] In this specific example, in combination with Figure 12The angle a between the peripheral portion 121 and the appliance body 101 is preferably an acute angle, and the range of the angle a is 80°-100°.

[0132] Here, the angle a between the mesial surface 1211 of the peripheral portion 121 and the appliance body 101 is an acute angle, and the range of the angle a is 85°-90°. In this case, when the cavity S1 is deformed by an abnormal force, the first opening 111 can be effectively prevented from being further torn.

[0133] In combination with Figure 13 FIG. 6 is a schematic view of a cross section of the fixed portion body 12 of the second specific example in a direction perpendicular to the buccal-lingual connecting line and cooperating with the archwire 202. For ease of description, the same or similar structures of the second specific example and the first specific example are denoted by the same or similar reference numerals, and the same applies hereinafter.

[0134] The main difference between the second specific example and the first specific example is that the stop portion 2021 of the second specific example is a block structure sleeved on the archwire 202. The stop portion 2021 can be integrally formed with the archwire 202, or the stop portion 2021 can be fixed on the archwire 202 by welding, bonding, clamping, or the like.

[0135] Here, when the cavity S1 is deformed by an abnormal force, the stop portion 2021 can effectively act on the junction area of the mesial surface 1211 and the appliance body 101 to make the cavity S1 as close to the tooth surface as possible, so as to offset the force acting on the cavity S1 as much as possible, thereby effectively preventing the first opening 111 from being further torn.

[0136] The other descriptions of the second specific example can refer to those of the other specific examples, which are not repeated here.

[0137] In combination with Figure 14 FIG. 7 is a schematic view of a cross section of the fixed portion body 12 of the third specific example in a direction perpendicular to the buccal-lingual connecting line and cooperating with the archwire 202.

[0138] The main difference between the third specific example and the first specific example is that the perforated portion 11 of the third specific example includes the first opening 111 on the mesial surface 1211 of the peripheral portion 121 and the second opening 112 on the distal surface 1212. That is, the first opening 111 and the second opening 112 are arranged face to face, the insertion end 203 extends along the mesial-distal direction and sequentially passes through the first opening 111, the cavity S1, and the second opening 112. In this way, the travel path of the insertion end 203 can be lengthened, thereby improving the cooperation strength between the insertion end 203 and the fixed portion body 12, and improving the deformation resistance of the cavity S1.

[0139] Here, the line connecting the first opening 111 and the second opening 112 is parallel to the mesial-distal direction, and the distance between the first opening 111 and the second opening 112 ranges from 1 mm to 8 mm.

[0140] Other descriptions of the third specific example can refer to other specific examples, which are not repeated here.

[0141] In combination Figure 15 A schematic view of the cross section of the fixed part body 12 of the fourth specific example in the direction perpendicular to the buccal-lingual line direction and cooperating with the arch wire 202.

[0142] The main difference between the fourth specific example and the first specific example is that the perforated part 11 of the fourth specific example includes the first opening 111 on the mesial surface 1211 of the peripheral part 121 and the second opening 112 on the top part 122, that is, the first opening 111 and the second opening 112 are adjacent to each other at this time, and the insertion end 203 is bent after passing through the first opening 111 and passes through the second opening 112.

[0143] Here, the second opening 112 is a blind hole, which can avoid the insertion end 203 penetrating out of the top part 122 to stimulate the oral mucosa tissue, of course, the second opening 112 can also be a through hole, and the insertion end 203 penetrating out of the top part 122 can be bent and closely attached to the top part 122.

[0144] Of course, in other specific examples, the second opening 112 can also be located on another surface of the peripheral part 121 connected to the mesial surface 1211, for example, the second opening 112 is located on the surface of the peripheral part 121 close to the gum.

[0145] Here, by bending the insertion end 203, the cooperation strength between the insertion end 203 and the fixed part body 12 can be improved, and the deformation resistance of the cavity S1 can also be improved.

[0146] Other descriptions of the fourth specific example can refer to other specific examples, which are not repeated here.

[0147] In combination Figure 16 A schematic view of the cross section of the fixed part body 12 of the fifth specific example in the direction perpendicular to the buccal-lingual line direction and cooperating with the arch wire 202.

[0148] The main difference between the fifth specific example and the first specific example is that the perforated part 11 of the fifth specific example includes the first opening 111 on the top part 122 and the second opening 112 on the distal surface 1212 of the peripheral part 121, that is, the first opening 111 and the second opening 112 are adjacent to each other at this time, and the insertion end 203 is bent after passing through the first opening 111 and passes through the second opening 112.

[0149] The first implementation form also provides a forming method of the dental instrument 100, which is taken as the dental orthodontic appliance 100 as an example, and can also be applied to the scene of an anchorage pin guide plate, an accessory installation template, and the like.

[0150] In combination Figure 17 The forming method of the dental instrument 100 includes the following steps:

[0151] adding an accessory at a target position of the dental model;

[0152] forming a semi-finished product by pressing a film, the semi-finished product having a cavity S1 corresponding to the accessory;

[0153] drilling a hole at the cavity S1, and cutting and demolding the semi-finished product to obtain the dental instrument 100.

[0154] Here, the “target position” refers to a position at which the cavity S1 (i.e., the fixed part body 12) needs to be formed, and the three steps of drilling, cutting, and demolding can be selected in a proper sequence according to actual conditions. The drilling step can form the first hole 111 on the cavity S1 or simultaneously form the first hole 111 and the second hole 112.

[0155] In combination Figures 18 to 28 In the second implementation form, the dental assembly 300a includes the dental instrument 100a and the functional piece 200a, the dental instrument 100a is a dental orthodontic appliance 100a, and the functional piece 200a is a lip bumper.

[0156] In the second implementation form, the dental orthodontic appliance 100a includes an appliance body 101a having a cavity S accommodating a tooth and a fixed part 10a protruding from the appliance body 101a toward a side away from the cavity S, and the fixed part 10a includes a through-hole part 11a into which an insertion end 203a of the functional piece 200a is inserted.

[0157] The fixed part 10a includes a fixed part body 12a and an embedded part 13a.

[0158] The fixed part body 12a surrounds to form a cavity S1 communicating with the cavity S, and the embedded part 13a is located in the cavity S1.

[0159] Optionally, the fixed part body 12a includes a peripheral part 121a and a top part 122a connected with each other, the peripheral part 121a is connected with the appliance body 101a, and the peripheral part 121a and the top part 122a surround to form the cavity S1.

[0160] The fixed part body 12a is substantially in a cap-shaped structure, a hollow structure in a middle part of the fixed part body 12a forms the cavity S1, the fixed part body 12a is integrally formed with the appliance body 101a, the forming process of the fixed part body 12a is simple, and the fixed part body 12a cooperates stably with the appliance body 101a.

[0161] The through hole 11a includes a first opening 111a penetrating the fixing portion body 12a and a channel 131a located in the embedded portion 13a and communicating with the first opening 111a, the insertion end 203a penetrates the first opening 111a and extends to the channel 131a, and the first opening 111a is located in the peripheral portion 121a or the top portion 122a.

[0162] Optionally, the embedded portion 13a is formed by a material filled in the cavity S1.

[0163] For example, the embedded portion 13a can be composed of a resin material, the insertion end 203a can be inserted into the cavity S1 in advance, and then the embedded portion 13a can be formed by filling the resin, so that various shapes of the insertion end 203a can be adapted, and the embedded portion 13a and the insertion end 203a can be tightly matched.

[0164] The embedded portion 13a has a block structure, and an outer surface of the embedded portion 13a contacts an inner surface of the fixing portion body 12a, that is, the embedded portion 13a can be filled in the cavity S1 as a filler.

[0165] Optionally, the embedded portion 13a can improve the overall strength of the entire fixing portion 10a, thereby improving the deformation resistance of the entire fixing portion 10a under the action of the force, and the insertion end 203a simultaneously penetrates the first opening 111a and the channel 131a, that is, the insertion end 203a simultaneously connects the fixing portion body 12a and the embedded portion 13a, which can greatly improve the stability of the matching between the insertion end 203a and the fixing portion 10a, thereby realizing effective transmission of the force of the arch wire 202a.

[0166] Optionally, the through hole 11a can further include a second opening 112a penetrating the fixing portion body 12a, and the channel 131a penetrates the embedded portion 13a, and the insertion end 203a sequentially penetrates the first opening 111a, the channel 131a and the second opening 112a, which can further improve the limiting effect between the insertion end 203a and the fixing portion 10a.

[0167] The first opening 111a is located in the peripheral portion 121a or the top portion 122a, and the second opening 112a is located in the peripheral portion 121a or the top portion 122a, but is not limited thereto, and the number and position of the openings of the through hole 11a can be determined according to actual conditions.

[0168] Optionally, the channel 131a has a linear type or an L type, but is not limited thereto.

[0169] Optionally, the insertion end 203a includes an insertion end body 2032a and a retaining structure 2031a protruding from the insertion end body 2032a, the retaining structure 2031a and the embedded portion 13a are limited to each other, thereby improving the limiting effect between the insertion end 203a and the fixing portion 10a.

[0170] Optionally, the inner profile of the channel 131a matches the outer profile of the insertion end 203a.

[0171] The channel 131a includes a portion accommodating the insertion end body 2032a and a portion accommodating the retention structure 2031a. When the embedding portion 13a is formed by the material filled in the cavity S1, the embedding portion 13a directly contacts the insertion end 203a during the filling process. The embedding portion 13a forms the inner profile of the channel 131a which completely matches the outer profile of the insertion end 203a. The embedding portion 13a is in complete contact with the insertion end 203a.

[0172] Optionally, the insertion end body 2032a extends along a first direction, and the retention structure 2031a extends along a second direction. The included angle between the first direction and the second direction is an acute angle, a right angle or an obtuse angle. The insertion end body 2032a and the retention structure 2031a are arranged at an angle. This can prevent the insertion end 203a from being separated from the channel 131a in the opposite direction of the insertion direction.

[0173] Optionally, a friction structure or at least one engagement structure is formed between the embedding portion 13a and the fixing portion body 12a. This can improve the fitting strength between the embedding portion 13a and the fixing portion body 12a.

[0174] In combination Figure 20 When the engagement structure is formed between the embedding portion 13a and the fixing portion body 12a, the engagement structure includes a mating engagement groove 132a and a protrusion 124a. One of the engagement groove 132a and the protrusion 124a is located in the embedding portion 13a, and the other is located in the fixing portion body 12a.

[0175] Here, the engagement groove 132a is located in the embedding portion 13a, and the protrusion 124a is located in the fixing portion body 12a. The engagement structure can be arranged close to the dental surface.

[0176] Optionally, the embedding portion 13a is away from the surface of the top portion 122a which contacts the dental surface. The embedding portion 13a includes a first material layer which contacts the dental surface and a second material layer which is away from the dental surface. The hardness of the first material layer is less than that of the second material layer.

[0177] The embedding portion 13a can include at least two materials. The softer material which contacts the dental surface can improve the wearing experience. The harder material which fills the cavity S1 away from the dental surface can further improve the strength of the cavity S1.

[0178] In other examples, the embedding portion 13a can not contact the dental surface away from the surface of the top portion 122a. In this case, there can be a gap between the embedding portion 13a and the dental surface.

[0179] Optionally, the cavity S formed by the fixing portion body 12a can be a rectangular cavity or a rectangular-like cavity.

[0180] The fixing portion body 12a is arranged corresponding to the buccal surface A1 or the lingual surface A2, in the direction parallel to the buccal surface A1, the cross-sectional profile of the fixing portion body 12a is rectangular, and the long side of the rectangle is parallel to the mesiodistal direction, in the direction perpendicular to the mesiodistal direction, the cross-sectional profile of the fixing portion body 12a is trapezoidal, but not limited thereto.

[0181] Optionally, the outer profile of the fixing portion body 12a gradually converges in the direction gradually approaching the tooth surface, that is, the outer profile size of the top portion 122a is larger than the outer profile size of the peripheral portion 121a at the connection of the appliance body 101a, which can avoid the embedded portion 13a from accidentally detaching from the cavity S1.

[0182] Next, several specific examples of the second implementation form are introduced.

[0183] In combination with Figure 21 , and Figure 22 , the schematic diagram of the cross section of the fixing portion 10a of the first specific example in the direction perpendicular to the buccal-lingual line cooperating with the archwire 202a is shown.

[0184] In the first specific example, the perforated portion 11a only includes the first opening 111a located on the mesial surface 1211a of the peripheral portion 121a and the channel 131a located in the embedded portion 13a, that is, the other areas of the fixing portion body 12a at this time are closed areas, the channel 131a is a straight half-penetrating channel (that is, the channel 131a does not completely penetrate the embedded portion 13a), and the insertion end 203a enters the channel 131a from the first opening 111a along the mesiodistal direction, at this time, the insertion end 203a can be prevented from slipping distally.

[0185] Here, when the insertion end 203a extends to the end of the channel 131a, the insertion end 203a and the embedded portion 13a achieve relative static, and the insertion end 203a cannot continue to move in the distal direction, at this time, the stop portion 2021 located at the archwire 202 in the first implementation form can be cancelled, of course, the stop portion 2021 can also not be cancelled if necessary.

[0186] In the present specific example, the distance between the center of the first opening 111a and the tooth surface is in the range of 0.8mm-4mm, and the first opening 111a is a circular hole, an elliptical hole or a polygonal hole with chamfer.

[0187] In the present specific example, in combination with Figure 22 , an included angle β is formed between the peripheral portion 121a and the appliance body 101a, and the included angle β can be in the range of 80°-120°, and preferably, the included angle β between at least part of the peripheral portion 121a and the appliance body 101a is an acute angle.

[0188] Here, taking the acute angle β between the distal surface 1212a of the peripheral portion 121a and the appliance body 101a as an example, the range of the angle β is 70°-90°, at this time, when the embedded portion 13a is deformed by abnormal force, the embedded portion 13a will not slip in the cavity S1 towards the tooth surface.

[0189] In combination Figure 23 The schematic view of the cross section of the fixed portion 10a of the second specific example in the direction perpendicular to the buccal-lingual connecting line and cooperating with the arch wire 202a, for the convenience of description, the same or similar structures of the second specific example and the first specific example adopt the same or similar numbers, and the same applies below.

[0190] The main difference between the second specific example and the first specific example is that the insertion end 203a of the second specific example includes an insertion end body 2032a and a retention structure 2031a protruding from the insertion end body 2032a, the retention structure 2031a is a bending structure connecting the end of the insertion end body 2032a, at this time, the channel 131a is an L-shaped channel, the setting of the retention structure 2031a can further avoid the insertion end 203a continuing to move in the distal direction, thereby improving the limiting effect between the insertion end 203a and the fixed portion 10a.

[0191] The retention structure 2031a and the insertion end body 2032a are integrally formed, for example, the retention structure 2031a and the insertion end body 2032a can be formed at the same time by bending the end region of the insertion end 203a.

[0192] The other descriptions of the second specific example can refer to other specific examples, which will not be repeated here.

[0193] In combination Figure 24 The schematic view of the cross section of the fixed portion 10a of the third specific example in the direction perpendicular to the buccal-lingual connecting line and cooperating with the arch wire 202a.

[0194] The main difference between the third specific example and the first specific example is that the insertion end 203a of the third specific example includes an insertion end body 2032a and a retention structure 2031a protruding from the insertion end body 2032a, the retention structure 2031a is a fence-like structure protruding from the insertion end body 2032a, at this time, the channel 131a is a special-shaped structure with multiple branch channels, the setting of the retention structure 2031a can further avoid the insertion end 203a continuing to move in the distal direction, thereby improving the limiting effect between the insertion end 203a and the fixed portion 10a.

[0195] The other descriptions of the third specific example can refer to other specific examples, which will not be repeated here.

[0196] In combinationFigure 25 A schematic view of the cross section of the fixed portion 10a of the fourth specific example in the direction perpendicular to the buccolingual line direction cooperating with the archwire 202a.

[0199] In combination Figure 26 A schematic view of the cross section of the fixed portion 10a of the fifth specific example in the direction perpendicular to the buccolingual line direction cooperating with the archwire 202a.

[0200] The main difference between the fifth specific example and the first specific example is that the perforated portion 11a of the fifth specific example comprises the first opening 111a located on the mesial surface 1211a of the peripheral portion 121a and the second opening 112a located on the distal surface 1212a, that is, the first opening 111a and the second opening 112a are arranged face to face at this time, and the insertion end 203a extends along the mesiodistal direction and sequentially passes through the first opening 111a, the channel 131a and the second opening 112a.

[0201] The insertion end 203a of the fifth specific example comprises an insertion end body 2032a and a retaining structure 2031a protruding from the insertion end body 2032a, the retaining structure 2031a is a columnar structure protruding from the insertion end body 2032a, and the retaining structure 2031a can further avoid the insertion end 203a from moving further in the distal direction, thereby improving the limiting effect between the insertion end 203a and the fixed portion 10a.

[0202] The other descriptions of the fifth specific example can refer to those of the other specific examples, which will not be repeated here.

[0203] In combination Figure 27 A schematic view of the cross section of the fixed portion 10a of the sixth specific example in the direction perpendicular to the buccolingual line direction cooperating with the archwire 202a.

[0204] The sixth specific example mainly differs from the first specific example in that the perforated portion 11a of the sixth specific example comprises the first opening 111a located on the mesial side surface 1211a of the peripheral portion 121a and the second opening 112a located on the distal side surface 1212a, that is, the first opening 111a and the second opening 112a are arranged face to face at this time, and the insertion end 203a extends along the mesial-distal direction and sequentially passes through the first opening 111a, the passage 131a and the second opening 112a.

[0205] The sixth specific example further comprises the stop portion 2021a located at the archwire 202a, the stop portion 2021a being a bending region of the archwire 202a, when the insertion end 203a enters the cavity S1, the stop portion 2021a abuts against the mesial side of the peripheral portion 121a to limit the length of the archwire 202a entering the cavity S1, and the force acting on the archwire 202a can be transmitted to the fixed portion 10a through the cooperation of the stop portion 2021a and the mesial side surface 1211a of the peripheral portion 121a.

[0206] The sixth specific example can refer to other specific examples for other descriptions, which will not be described here.

[0207] In combination Figure 28 The seventh specific example of the fixed portion 10a in the direction perpendicular to the buccal-lingual side connecting line cooperates with the archwire 202a.

[0208] The seventh specific example mainly differs from the first specific example in that the perforated portion 11a of the seventh specific example comprises the first opening 111a located on the mesial side surface 1211a of the peripheral portion 121a and the second opening 112a located on the top portion 122a, that is, the first opening 111a and the second opening 112a are arranged adjacent to each other at this time, the passage 131a is L-shaped, the insertion end 203a is bent after passing through the first opening 111a and passes through the second opening 112a, and the second opening 112a can further limit the insertion end 203a.

[0209] The end of the insertion end 203a is bent, and the portion of the insertion end 203a extending to the second opening 112a can also be regarded as the retaining structure as described above.

[0210] Optionally, the second opening 112a is a blind hole, which can avoid the insertion end 203a penetrating out of the top portion 122a to stimulate the oral mucosa tissue, of course, the second opening 112a can also be a through hole, and the insertion end 203a penetrating out of the top portion 122a can be bent and closely attached to the top portion 122a.

[0211] Of course, in other specific examples, the second opening 112a can also be located on the proximal mesial surface 1211a and on another surface of the peripheral portion 121a, for example, on the surface of the peripheral portion 121a close to the gingiva.

[0212] Other descriptions of the seventh specific example can refer to other specific examples, which are not described here again.

[0213] The second implementation form also provides a forming method of the dental assembly 300a, in combination with Figure 29 The forming method comprises the steps of:

[0214] The forming method of the dental appliance 100 according to the first implementation form obtains the dental appliance 100a with the cavity S1 and the first opening 111a (or the first opening 111a and the second opening 112a);

[0215] The free end of the archwire 202a of the functional element 200a is inserted into the cavity S1 from the first opening 111a;

[0216] The resin is filled in the cavity S1;

[0217] The resin is photocured to obtain the dental assembly 300a.

[0218] Here, the resin after photocuring forms the embedding portion 13a as described above, and the part in the embedding portion 13a corresponding to the insertion end 203a is the channel 131a.

[0219] It can be understood that since the embedding portion 13a is post-formed, the form of the insertion end 203a at this time is not constrained by the embedding portion 13a, and the insertion end 203a can form the retention structure 2031a as described above, or in other words, the insertion end 203a at this time can be bent according to actual needs, so that the cooperation strength between the insertion end 203a and the embedding portion 13a can be improved, and the movement of the insertion end 203a in the distal direction can be constrained (i.e., the stop portion 2021 in the first implementation form can be omitted).

[0220] In combination with Figures 30 to 39 In the third implementation form, the dental assembly 300b comprises a dental appliance 100b and a functional element 200b, the dental appliance 100b is an orthodontic appliance 100b, and the functional element 200b is a lip bumper.

[0222] The fixing portion 10b comprises a fixing portion body 12b and an embedded portion 13b.

[0223] The fixing portion body 12b surrounds a cavity S1 forming the communication cavity S, and the embedded portion 13b is a pre-formed member installed in the cavity S1.

[0224] Optionally, the fixing portion body 12b comprises a peripheral portion 121b and a top portion 122b connected with each other, the peripheral portion 121b is connected with the appliance body 101b, and the peripheral portion 121b and the top portion 122b surround the cavity S1.

[0225] The fixing portion body 12b is generally in a cap-shaped structure, a hollow structure in the middle of the fixing portion body 12b forms the cavity S1, the fixing portion body 12b is integrally formed with the appliance body 101b, the forming process of the fixing portion body 12b is simple, and the fixing portion body 12b is stably matched with the appliance body 101b.

[0226] Optionally, the perforated portion 11b comprises a first opening 111b penetrating through the fixing portion body 12b and a channel 131b located at the embedded portion 13b and communicating with the first opening 111b, the insertion end 203b penetrates through the first opening 111b and extends to the channel 131b, and the first opening 111b is located at the peripheral portion 121b or the top portion 122b.

[0227] The third implementation form is mainly different from the second implementation form in that the embedded portion 13b of the third implementation form is a pre-formed member, and the channel 131b is pre-formed at the embedded portion 13b, that is, the channel 131b is a structure pre-formed at the embedded portion 13b, the pre-formed member can improve the strength of the embedded portion 13b, and is convenient for installation and use.

[0228] Considering the difficulty of inserting the insertion end 203b into the channel 131b, the channel 131b is provided as a straight channel, and the insertion end 203a is also generally in a straight structure extending in the distal direction.

[0229] Optionally, the embedded portion 13b can improve the overall strength of the entire fixing portion 10b, thereby improving the deformation resistance of the entire fixing portion 10b under the action of force, and the insertion end 203b simultaneously penetrates through the first opening 111b and the channel 131b, that is, the insertion end 203b simultaneously connects the fixing portion body 12b and the embedded portion 13b, which can greatly improve the stability of the cooperation between the insertion end 203b and the fixing portion 10b, thereby realizing effective transmission of the force of the arch wire 202b.

[0230] The through hole 11b can further comprise a second opening 112b penetrating the fixing portion body 12b, and the channel 131b penetrating the embedding portion 13b, the channel 131b connecting the first opening 111b and the second opening 112b, and the insertion end 203b sequentially penetrating the first opening 111b, the channel 131b and the second opening 112b, so as to further improve the limiting effect between the insertion end 203b and the fixing portion 10b.

[0231] The connecting direction of the first opening 111b, the channel 131b and the second opening 112b is parallel to the mesial-distal direction, and the interval between the first opening 111b and the second opening 112b ranges from 1mm to 8mm.

[0232] Optionally, a friction structure or at least one clamping structure is formed between the embedding portion 13b and the fixing portion body 12b, so as to improve the cooperation strength between the embedding portion 13b and the fixing portion body 12b.

[0233] In combination Figure 32 When the clamping structure is formed between the embedding portion 13b and the fixing portion body 12b, the clamping structure comprises a clamping groove 132b and a protrusion 124b which cooperate with each other, and one of the clamping groove 132b and the protrusion 124b is located in the embedding portion 13b, and the other is located in the fixing portion body 12b.

[0234] Here, the clamping structure is taken as an example that the clamping groove 132b is located in the embedding portion 13b and the protrusion 124b is located in the fixing portion body 12b, and the clamping structure can be arranged close to the dental surface.

[0235] Optionally, the cavity S formed by the fixing portion body 12b can be a rectangular cavity or a similar rectangular cavity.

[0236] The fixing portion body 12b is arranged corresponding to the buccal surface A1 or the lingual surface A2, and in the direction parallel to the buccal surface A1, the cross-sectional profile of the fixing portion body 12b is rectangular, and the long side of the rectangle is parallel to the mesial-distal direction, and in the direction perpendicular to the mesial-distal direction, the cross-sectional profile of the fixing portion body 12b is trapezoidal, but not limited thereto.

[0237] Optionally, the outer profile of the fixing portion body 12b gradually converges in the direction gradually close to the dental surface, that is, the outer profile size of the top portion 122b is larger than the outer profile size of the peripheral portion 121b connected to the aligner body 101b, so as to avoid the embedding portion 13b from accidentally separating from the cavity S1.

[0238] Optionally, in combination Figure 33 and Figure 34 A schematic view of the embedding portion 13b which is pre-formed.

[0239] The channel 131b embedded in the embedding portion 13b includes a first channel 1311b close to the first opening 111b and a second channel 1312b connected to the first channel 1311b, and the opening diameter of the first channel 1311b is greater than or equal to the opening diameter of the second channel 1312b.

[0240] That is, in general, the opening diameter of the part of the channel 131b close to the first opening 111b is larger, so that the embedding portion 13b can be prevented from being damaged when the first opening 111b is formed at the cavity S1 where the embedding portion 13b is installed. Of course, the opening diameter of the first channel 1311b can be equal to the opening diameter of the second channel 1312b.

[0241] Similarly, when the fixing portion body 12b includes both the first opening 111b and the second opening 112b, the second channel 1312b away from the first channel 1311b further includes a third channel 1313b, and the opening diameter of the third channel 1313b is greater than the opening diameter of the second channel 1312b.

[0242] That is, at this time, the entire channel 131b is in the form of small in the middle and large at both ends, which can prevent the embedding portion 13b from being damaged in the subsequent opening process.

[0243] In addition, the inner contour of the second channel 1312b can be matched with the outer contour of the insertion end 203b to realize the mutual limiting of the second channel 1312b and the insertion end 203b. For example, the inner contour section of the second channel 1312b and the outer contour section of the insertion end 203b are both rectangular or circular, etc. The first channel 1311b and the third channel 1313b mainly play a role in avoiding during the opening process, and the form of the inner contour section of the first channel 1311b and the third channel 1313b is not required.

[0244] Next, several specific examples of the third implementation form are introduced.

[0245] In combination with Figure 35 and Figure 36 the schematic view of the cross section of the fixing portion 10b perpendicular to the buccal-lingual side connecting line direction cooperating with the archwire 202b is shown.

[0246] In the first specific example, the perforated portion 11b only includes the first opening 111b located on the mesial surface 1211b of the peripheral portion 121b and the channel 131b embedded in the embedding portion 13b, that is, the other regions of the fixing portion body 12b at this time are closed regions.

[0247] The channel 131b is a straight semi-penetrating channel (i.e., the channel 131b does not completely penetrate the embedding portion 13b), and the insertion end 203b enters the channel 131b from the first opening 111b in the mesial-distal direction. At this time, the insertion end 203b can be prevented from slipping distally.

[0248] Here, when the insertion end 203b extends to the end of the channel 131b, the insertion end 203b and the embedding portion 13b are relatively stationary, and the insertion end 203b cannot continue to move in the distal direction.

[0249] In the present specific example, the distance between the center of the first opening 111b and the tooth surface is in the range of 0.8 mm-4 mm, and the first opening 111b is a circular hole, an elliptical hole, or a polygonal hole with chamfered corners.

[0250] In the present specific example, an included angle β is formed between the peripheral portion 121b and the appliance body 101b, and the included angle β can be in the range of 80°-120°. Preferably, the included angle β between at least part of the peripheral portion 121b and the appliance body 101b is an acute angle.

[0251] Here, taking the acute angle β between the mesial surface 1212b of the peripheral portion 121b and the appliance body 101b as an example, the included angle β is in the range of 70°-90°. At this time, when the embedding portion 13b is deformed by an abnormal force, the embedding portion 13b will not slip in the cavity S1 toward the tooth surface.

[0252] In combination Figure 37 The sectional view of the fixed portion 10b of the second specific example in the direction perpendicular to the buccal-lingual line is shown in cooperation with the archwire 202b.

[0253] The main difference between the second specific example and the first specific example is that the insertion end 203b of the second specific example does not extend to the end of the channel 131b, but a stop portion 2021b is formed near the insertion end 203b to limit the movement of the insertion end 203b in the distal direction.

[0254] Specifically, the dental assembly 300b includes a stop portion 2021b connected to the insertion end 203b, and the surrounding area of the first opening 111b cooperates with the stop portion 2021b to limit the movement of the archwire 202b into the channel 131b. The stop portion 2021b is a bending region of the archwire 202b, so that the force of the archwire 202b can be more effectively transmitted to the fixed portion 10b.

[0255] The other descriptions of the second specific example can refer to those of the other specific examples, and will not be repeated here.

[0256] In combination Figure 38Fig. 6 is a schematic view of a cross section of the fixed portion 10b of the third specific example in cooperation with the archwire 202b in a direction perpendicular to the buccal-lingual connecting line direction.

[0257] The main difference between the third specific example and the first specific example is that the perforated portion 11b of the third specific example includes the first opening 111b on the mesial surface 1211b of the peripheral portion 121b and the second opening 112b on the distal surface 1212b, the channel 131b is a straight channel, and the connecting line of the first opening 111b, the channel 131b, and the second opening 112b is parallel to the mesial-distal direction.

[0258] The insertion end 203b is limited to continue to move in the distal direction by forming a stop portion 2021b in the area close to the insertion end 203b, and the stop portion 2021b is a bending area of the archwire 202b.

[0259] Here, the second opening 112b is a through hole, and in other specific examples, the second opening 112b can also be a blind hole.

[0260] Other descriptions of the third specific example can refer to other specific examples and will not be repeated here.

[0261] In combination Figure 39 Fig. 7 is a schematic view of a cross section of the fixed portion 10b of the fourth specific example in cooperation with the archwire 202b in a direction perpendicular to the buccal-lingual connecting line direction.

[0262] The main difference between the fourth specific example and the third specific example is that the stop portion 2021b of the fourth specific example is a block structure sleeved on the archwire 202b.

[0263] Other descriptions of the fourth specific example can refer to other specific examples and will not be repeated here.

[0264] The third implementation form also provides a forming method of the dental instrument 100b, in combination Figure 40 The forming method includes the steps of:

[0265] The forming method of the dental instrument 100 according to the first implementation form obtains the dental instrument 100b with the cavity S1 and the first opening 111b (or the first opening 111b and the second opening 112b);

[0266] The embedded portion 13b is inserted into the cavity S1, and the channel 131b of the embedded portion 13b is in communication with the first opening 111b.

[0267] That is, the cavity S1 and the first opening 111b are formed first, and then the embedded portion 13b is pre-formed and installed into the cavity S1.

[0268] In combination Figures 41 to 43The third implementation form also provides another forming method of the dental instrument 100b, and the forming method comprises the following steps:

[0269] S1: providing a dental mold 400b, the dental mold 400b is provided with an embedded part 13b at a target position, the embedded part 13b is a pre-formed part, and the embedded part 13b is provided with a channel 131b.

[0270] Optionally, the embedded part 13b can be formed together with the dental mold 400b, and the embedded part 13b is weakly connected with the dental mold 400b, or the embedded part 13b is a structure that is subsequently added to the dental mold 400b, and here, the embedded part 13b is taken as an example of the structure that is subsequently added to the dental mold 400b.

[0271] The step S1 specifically comprises the following steps:

[0272] providing a dental mold 400b;

[0273] adding an embedded part 13b at a target position of the dental mold 400b.

[0274] In combination with Figure 42 The step S1 specifically comprises the following steps:

[0275] adding a hanging part 401b at the target position of the dental mold 400b;

[0276] installing the embedded part 13b at the hanging part 401b, and the embedded part 13b comprises a groove 133b that cooperates with the hanging part 401b.

[0277] Here, the specific Figure 34 The embedded part 13b is provided with a groove 133b that penetrates the bottom surface of the embedded part 13b below the channel 131b, and the groove 133b can be a full-through groove that penetrates in the mesial-distal direction, or a half-through groove that does not penetrate in the mesial-distal direction.

[0278] When the groove 133b is a full-through groove, the full-through groove does not have a wall in the mesial-distal direction, and the full-through groove is inserted into the side of the hanging part 401b to realize the cooperation between the full-through groove and the hanging part 401b.

[0279] When the groove 133b is a half-through groove, the half-through groove has a wall structure in the mesial-distal direction, and at this time, the half-through groove needs to be clamped to the hanging part 401b in the direction close to the dental surface.

[0280] In addition, the step S1 can further comprise the following steps:

[0281] In combination with Figure 43 The embedded part 13b is added at the target position of the dental mold 400b, and a support part 402b is added at a region adjacent to the target position of the dental mold 400b, and the support part 402b is located on a side of the embedded part 13b close to the gum.

[0282] Here, the embedding portion 13b is in a block structure, and specifically, the embedding portion 13b is in an inverted trapezoidal structure. When the subsequent film pressing operation is performed, the embedding portion 13b cannot be tightly pressed, and wrinkles can occur. Since the film pressing direction is the occlusal surface towards the gingival direction, the area above the embedding portion 13b (i.e., the area close to the occlusal surface) is pressed more fully, and the probability of wrinkles is not high. The area close to the gingival is prone to wrinkles, and the support portion 402b formed in this area can provide a transition for the film pressing process, thereby avoiding the occurrence of wrinkles.

[0283] Here, the end of the support portion 402b close to the gingival is preferably in a beveled structure, which can better achieve the film pressing transition. The support portion 402b can be directly abutted with the embedding portion 13b, and a gap can also be formed between the support portion 402b and the embedding portion 13b.

[0284] S2: The film pressing forms a semi-finished product, and the semi-finished product has a cavity S1 corresponding to the embedding portion 13b;

[0285] S3: A hole is formed at the cavity S1, and the semi-finished product is cut and demolded to obtain the dental instrument 100b. The hole and the channel 131b are in communication with each other, and the dental instrument 100b includes the embedding portion 13b accommodated in the cavity S1.

[0286] Here, the embedding portion 13b and the hanging portion 401b form a weak fit. When demolding, the embedding portion 13b is separated from the hanging portion 401b and leaves the cavity S1 together with the dental mold 400b. Therefore, the dental instrument 100b obtained by demolding includes the embedding portion 13b accommodated in the cavity S1.

[0287] In addition, during the hole forming process, as described above, since the opening diameter of the channel 131b close to the hole position is large, the embedding portion 13b can be prevented from being damaged during the hole forming process.

[0288] The third implementation form also provides a forming method of the dental assembly 300b, including the steps of:

[0289] Obtaining the dental instrument 100b with the embedding portion 13b and the first hole 111b (or the first hole 111b and the second hole 112b);

[0290] Inserting the free end of the archwire 202b into the channel 131b from the first hole 111b to obtain the dental assembly 300b.

[0298] The embedding portion 13c remaining on the dental surface as an attachment has the channel 131c and can be used in cooperation with an arch wire or other structures in the future, and when the dental surface has a plurality of embedding portions 13c, the arch wire 700c can be used to connect the plurality of embedding portions 13c to form a segment arch, as Figure 46 shown.

[0299] Optionally, the embedding portion 13c remaining on the dental surface as an attachment can be used as an independent attachment or used in combination with an orthodontic appliance to achieve combined treatment.

[0300] Optionally, the embedding portion 13c is formed by a material filled in the hollow cavity S1.

[0301] The dental assembly 300c at this time further comprises a functional piece 200c, the functional piece 200c being an archwire 200c connected to the attachment installation template 100c, a free end of the archwire 200c being inserted into the first opening 111c as an insertion end 203c and extending to the channel 131c.

[0302] In actual application, the insertion end 203c of the archwire 200c is inserted into the cavity S1 from the first opening 111c first, then the resin material is filled into the cavity S1 and connected to the dental surface, and after the resin material is solidified, the archwire 200c is pulled out and the template body 101c is removed, the embedding part 13c formed by the resin material and having the channel 131c is adhered to the dental surface, and thus the attachment installation is completed.

[0303] Optionally, the embedding part 13c can also be a pre-formed piece, and the channel 131c is a structure pre-formed in the embedding part 13c, at this time, the archwire 200c can be cancelled, and the embedding part 13c is directly installed to the dental surface through the attachment installation template 100c.

[0304] Other descriptions of the fourth implementation form can refer to other implementation forms, which will not be described here again.

[0415] The embedded portion 13k is a pre-formed piece installed in the cavity S1, but is not limited thereto, and the embedded portion 13k can also be in other forms, for example, the embedded portion 13k is formed by a material filled in the cavity S1, and the material can be pre-filled in the cavity S1 before the anchorage nail 200k is implanted.

[0416] The sleeve 14k is fixed in the fixing part body 12k through the embedded portion 13k, which can improve the retention stability of the sleeve 14k, thereby improving the guiding effect of the sleeve 14k on the anchorage nail 200k and improving the accuracy of implantation of the anchorage nail 200k.

[0417] Other descriptions of the tenth implementation form can refer to other implementation forms, which will not be repeated here.

[0419] In a eleventh implementation form of the dental assembly 300m, the dental appliance 100m is an orthodontic appliance 100m, and the functional piece 200m is a functional piece 200m.

[0420] The fixing portion 10m further comprises a fixing portion body 12m, the fixing portion body 12m surrounds to form a cavity S1 communicating with the cavity S.

[0421] Optionally, the fixing portion body 12m comprises a peripheral portion 121m and a top portion 122m connected with each other, the peripheral portion 121m is connected with the appliance body 101m, and the peripheral portion 121m and the top portion 122m surround to form the cavity S1.

[0422] The fixing portion body 12m is substantially a cap-shaped structure, a hollow structure in the middle of the fixing portion body 12m forms the cavity S1, the fixing portion body 12m is integrally formed with the appliance body 101m, the forming process of the fixing portion body 12m is simple, and the fixing portion body 12m cooperates with the appliance body 101m stably.

[0427] The functional element 200m includes a functional element body 204m and an arch wire 202m connected to the functional element body 204m, and the insertion ends 203m are free ends of the arch wire 202m.

[0428] Optionally, the two insertion ends 203m are two free ends of the arch wire 202m of the same functional element 200m.

[0429] Specifically, the functional element body 204m is located at the middle part of the arch wire 202m, and the arch wire 202m includes two free ends away from the functional element body 204m, that is, the arch wire 202m includes two parts located on both sides of the functional element body 204m, and the two ends of the two parts away from the functional element body 204m are the two free ends.

[0430] The functional element body 204m may be, for example, a tongue training element, a traction buckle, etc. For example, taking the case where the functional element body 204m is a palatal bead movably sleeved on the arch wire 202m as an example, the palatal bead can perform tongue training, and the fixing portion 10m can be located on the lingual surface A2 of the appliance body 101m, but the disclosure is not limited thereto, and in other implementation forms, the fixing portion 10m can also be located on the buccal surface of the appliance body 101m.

[0432] The two ends of the arch wire 202m away from the functional element body 204m can be bent inward to form the two insertion ends 203m and the two stop portions 2021m, and at this time, the functional element 200m is roughly a ring structure with an opening formed between the two insertion ends 203m and used for matching the fixing portion body 12m.

[0433] Optionally, the stop portion can also be a block structure sleeved on the arch wire 202m, and specific reference can be made to other implementation forms, or the two insertion ends 203m can abut against the inner wall or other structures in the cavity S1 to realize the stop.

[0434] Other descriptions of the eleventh implementation form can be referred to the other implementation forms, which will not be described here.

[0435] In combination with Figure 69 andFigure 70 In a twelfth implementation form, the dental assembly 300n comprises the dental appliance 100n and the functional piece 200n, wherein the dental appliance 100n is an orthodontic appliance 100n.

[0436] The main difference between the twelfth implementation form and the eleventh implementation form is that the twelfth implementation form further comprises the embedded portion 13n in the cavity S1.

[0437] The perforated portion 11n further comprises a passage 131n in the embedded portion 13n and communicating with the first opening 111n, and an additional passage 131n’ in the embedded portion 13n and communicating with the second opening 112n, one of the two insertion ends 203n extends through the first opening 111n and into the passage 131n, and the other extends through the second opening 112n and into the additional passage 131n’.

[0438] The embedded portion 13n can improve the overall strength of the entire fixing portion 10n, and thus improve the deformation resistance of the entire fixing portion 10n under the action of the force; one of the insertion ends 203n extends through the first opening 111n and the passage 131n, and the other extends through the second opening 112n and the additional passage 131n’, i.e., the insertion ends 203n connect the fixing portion body 12n and the embedded portion 13n at the same time, which can greatly improve the stability of the cooperation between the insertion ends 203n and the fixing portion 10n, and thus improve the mutual fixing strength between the functional piece 200n and the fixing portion 10n.

[0439] Optionally, the additional passage 131n’ and the passage 131n are in communication with each other, or the additional passage 131n’ and the passage 131n are arranged in a staggered manner.

[0440] This implementation form takes the example that the additional passage 131n’ and the passage 131n are in communication with each other, i.e., the passage 131n communicates the first opening 111n and the second opening 112n, and the two insertion ends 203n extend through the first opening 111n and the second opening 112n and into the passage 131n, respectively.

[0443] That is, generally, the portion of the channel 131n close to the first opening 111n has a larger opening diameter, so that the first opening 111n can be formed without damaging the embedded part 13n at the cavity S1 where the embedded part 13n is installed. Of course, the opening diameter of the first channel 1311n can be equal to the opening diameter of the second channel 1312n.

[0444] Similarly, the second channel 1312n away from the first channel 1311n also includes a third channel 1313n, and the opening diameter of the third channel 1313n is larger than that of the second channel 1312n.

[0445] That is, the entire channel 131n at this time is in the form of small in the middle and large at both ends, which can avoid damaging the embedded part 13n in the subsequent opening process.

[0446] Optionally, the embedded part 13n is a pre-formed part installed in the cavity S1, and the channel 131n is a structure pre-formed in the embedded part 13n, but not limited thereto.

After the sleeve 14p passes through the first opening 111p and extends to the cavity S1, the open end of the hole 141p is located on the outside so that the insertion end 203p is inserted.

[0451] The sleeve 14p and the fixing part 10p are detachably connected, that is, the sleeve 14p is detachably installed to the fixing part body 12p. Different types of sleeves 14p can be installed to the same fixing part body 12p, and by replacing sleeves 14p with different inner diameters, it is convenient to adapt to arch wires 202p with different diameters.

[0464] In the fifteenth implementation form, the dental orthodontic appliance 100t includes the appliance body 101t having the cavity S accommodating the tooth and the fixing part 10t protruding from the appliance body 101t towards a side away from the cavity S, and the fixing part 10t includes the perforated part 11t for inserting the insertion end 203t of the functional piece 200t.

[0467] The fixing part body 12t is generally in a cap-shaped structure, the hollow structure in the middle of the fixing part body 12t forms the cavity S1, the fixing part body 12t is integrally formed with the appliance body 101t, the forming process of the fixing part body 12t is simple, and the fixing part body 12t cooperates stably with the appliance body 101t.

[0468] The perforated part 11t includes the first opening 111t and the second opening 112t penetrating through the fixing part body 12t, and the first opening 111t and the second opening 112t are arranged at intervals.

[0469] Optionally, the first opening 111t and the second opening 112t are respectively located in the two fixing parts 10t arranged at intervals, and the two fixing parts 10t are respectively the first fixing part 10t and the second fixing part 10t’, the first opening 111t is located in the peripheral part 121t or the top part 122t of the first fixing part 10t, and the second opening 112t is located in the peripheral part 121t’ or the top part 122t’ of the second fixing part 10t’.

[0471] The functional member 200t includes two insertion ends 203t, which pass through the first opening 111t and the second opening 112t and extend into the cavity S1, i.e., one of the two insertion ends 203t is inserted into the cavity S1 of the first fixing portion 10t from one side of the first opening 111t, and the other is inserted into the cavity S1 of the second fixing portion 10t' from one side of the second opening 112t.

[0472] The functional member 200t includes a functional member body 204t and an archwire 202t connected to the functional member body 204t, and the insertion end 203t is a free end of the archwire 202t.

[0473] Optionally, the two insertion ends 203t are two free ends of the archwire 202t of the same functional member 200t.

[0474] Specifically, the functional member body 204t is located at the middle portion of the archwire 202t, and the archwire 202t includes two free ends away from the functional member body 204t, i.e., the archwire 202t includes two portions located at the two sides of the functional member body 204t, and the two ends of the two portions away from the functional member body 204t are the two free ends.

[0476] Compared with the eleventh implementation form, in the fifteenth implementation form, since one functional member 200t simultaneously connects the first fixing portion 10t and the second fixing portion 10t' arranged at intervals, the length of the archwire 202t between the first opening 111t and the second opening 112t is relatively longer, the palatal bead 204t (i.e., the functional member body 204t) sleeved on the archwire 202t can move back and forth in the mesial-distal direction relative to the archwire 202t, the movement range of the palatal bead is wider, and the degree of freedom of tongue training can be improved.

[0489] Optionally, the number of tooth positions between the two tooth positions corresponding to the first fixed portion 10u and the second fixed portion 10u' is not more than two, and specific reference can be made to the description of the fifteenth implementation form.

[0490] Optionally, the dental assembly 300u further includes two stop portions 2021u connecting the two free ends (i.e., the two insertion ends 203u), and the surrounding regions of the first opening 111u and the second opening 112u are respectively matched with the two stop portions 2021u to limit the movement of the arch wire 202u towards the cavity S1, and the stop portion 2021u is a bending region of the arch wire 202u.

[0491] The two ends of the arch wire 202u away from the functional piece body 204u can be bent inward to form the two insertion ends 203u and the two stop portions 2021u, and at this time, the functional piece 200u is roughly a ring structure with an opening formed between the two insertion ends 203u and used for matching the two fixed portions.

[0492] Optionally, the stop portion can also be a block structure sleeved on the arch wire 202u, or the two insertion ends 203u can abut against the inner wall or other structures in the cavity S1 to achieve the stop.
