[0034] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0035] Combination Figures 1 to 7 , which is a schematic diagram of a dental component 300 according to an embodiment of the present invention.

[0036] The dental assembly 300 includes a functional part 200 and a dental instrument 100 .

[0037] The dental instrument 100 includes an instrument body 101 having a cavity S and a fixing portion 10 protruding out of the instrument body 101 toward a side away from the cavity S.

[0038] The fixing part 10 has a perforated part 11 , and the insertion end 203 of the functional part 200 is limited in the perforated part 11 , so that the dental instrument 100 and the functional part 200 can be connected to each other, and the insertion end 203 is limited in the perforated part 11 to realize the position limitation of the functional part 200 .

[0039] The dental instrument 100 may be an orthodontic appliance, an anchor pin guide plate, etc.

[0040] In one application scenario of the present invention, combined with Figures 1 to 7 , the dental instrument 100 is taken as an example of a dental orthodontic appliance 100.

[0041] The dental orthodontic appliance 100 may be, for example, an invisible appliance, and the functional component 200 may be, for example, an archwire-like structure, but is not limited thereto.

[0042] Invisible braces can be a shell-like structure made of polymer materials.

[0043] Archwire structures include extraoral arches, lip stops, depression or expansion auxiliary arches, etc. Figure 1 and Figure 2 As shown, the functional part 200 is shown as a lip stopper. Figure 3 As shown, the functional part 200 is shown as an extraoral bow. Figure 4 As shown, it is shown that the functional part 200 is to press down the auxiliary bow, such as Figure 5 and Figure 6 As shown, the functional part 200 is illustrated as an auxiliary bow for bow expansion.

[0044] Figure 1 and Figure 2The lip stop shown includes an action portion 201 arranged corresponding to the front teeth area and an arch wire 202 connected to both sides of the action portion 201 and extending distally. The action portion 201 contacts and interacts with the upper lip, and the arch wire 202 is connected to two fixing portions 10 on the buccal surface A1 of the dental orthodontic appliance 100.

[0045] Figure 3 The extraoral arch shown includes an archwire 202 connected to two fixing portions 10 on the buccal surface A1 of the orthodontic appliance 100 .

[0046] Figure 4 The depression auxiliary arch shown includes an arch wire 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 arch wire 202 abuts against the traction buckle 500 .

[0047] Figure 5 The shown expansion auxiliary arch includes an arch wire 202, which is connected to two fixing parts 10 of the lingual surface A2 of the dental orthodontic appliance 100.

[0048] Figure 6 The shown expansion auxiliary arch includes an arch wire 202, the middle portion of the arch wire 202 passes through the fixing portion 10 of the lingual surface A2 of the dental orthodontic appliance 100, and both ends of the arch wire 202 pass through two groove structures 600 of the lingual surface A2 of the dental orthodontic appliance 100.

[0049] The dental orthodontic appliance 100 includes an appliance body 101 having a cavity S for accommodating teeth, and a fixing portion 10 protruding from the appliance body 101 toward a side away from the cavity S, that is, the instrument body 101 at this time is the appliance body 101, and the fixing portion 10 is located on the buccal surface A1 or the lingual surface A2 of the appliance body 101.

[0050] Taking the functional part 200 as a lip stopper as an example, the fixing part 10 is set corresponding to the buccal surface A1 of the posterior tooth area, the dental component 300 includes two fixing parts 10 located in two posterior tooth areas of the same jaw, and the functional part 200 includes two insertion ends 203, and the two insertion ends 203 match the two fixing parts 10 one by one.

[0051] The two arch wires 202 of the action part 201 connected to the lip stop extend toward the two distal directions on the left and right sides respectively, and the two free ends of the two arch wires 202 away from the lip stop are defined as two insertion ends 203. The entrance of the perforated part 11 of the fixing part 10 is located on the mesial side of the fixing part 10, and the insertion end 203 enters the perforated part 11 from the entrance of the perforated part 11 to realize the connection between the functional part 200 and the dental orthodontic appliance 100.

[0052] In actual application, when the upper lip interacts with the acting part 201 of the lip stop, the acting force is transmitted to the fixing part 10 through the arch wire 202, and then the fixing part 10 transmits the acting force to the dental orthodontic appliance 100 to achieve distal movement of the molars in the posterior tooth area.

[0053] Of course, in other application scenarios, when the functional part 200 is a non-archwire structure, the insertion end 203 may not be the free end of the archwire, and the insertion end 203 may be other structures. In addition, the fixing portion 10 may also be set corresponding to other areas of the tooth (for example, Figure 5 , Figure 6 The fixing portion 10 shown is arranged corresponding to the tongue surface A2), and the entrance of the perforated portion 11 may also be located at other positions.

[0054] The insertion end 203 enters the fixing portion 10 through the perforated portion 11 to achieve mutual limitation between the insertion end 203 and the fixing portion 10 , thereby achieving effective cooperation between the functional component 200 and the dental orthodontic appliance 100 .

[0055] Optionally, in each correction step, the spatial relative position of the fixing part 10 and the target point remains unchanged.

[0056] The target point refers to a point that does not move during the correction process. For example, the target point is a point on the maxillary tissue or a point in the front tooth area. Alternatively, the target point is a virtual point in the software design process, such as a point on the CBCT corresponding to the nose, etc.

[0057] In each correction step, the spatial relative position of the fixing 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 fixing part 10) remains unchanged, thereby achieving continuous and stable force application by the functional part 200.

[0058] At this time, the combined portion of the functional component 200 and the dental orthodontic appliance 100 (ie, the fixing portion 10 ) is movable relative to the teeth to be corrected (teeth in the posterior region).

[0059] Optionally, the free end of the arch wire 202 (i.e., the insertion end 203) enters the perforated portion 11 from the entrance of the perforated portion 11, and the dental component 300 further includes a stop portion 2021 connected to the insertion end 203, and the surrounding area of ​​the entrance cooperates with the stop portion 2021 to limit the movement of the arch wire 202 toward the perforated portion 11, that is, to prevent the arch wire 202 from continuing to move in the distal direction and excessively entering the perforated portion 11. In this way, the force of the arch wire 202 can be more effectively transmitted to the fixing portion 10.

[0060] In addition, at least one U-shaped curved portion 2022 is formed at the arch wire 202. The U-shaped curved portion 2022 is located between the stop portion 2021 and the action portion 201. The U-shaped curved portion 2022 can be used to adjust the length of the arch wire 202 in the mesiodistal direction.

[0061] Optionally, the dental orthodontic appliance 100 also includes a reinforcing portion 20 arranged adjacent to the fixed portion 10, the reinforcing portion 20 protrudes out of the appliance body 101 toward the side away from the cavity S, and the reinforcing portion 20 forms an accommodating cavity S2 for accommodating tooth surface accessories, and the height of the reinforcing portion 20 is less than the height of the fixed portion 10.

[0062] Optionally, accessories can be pre-added on the tooth surface. When the dental orthodontic appliance 100 is worn, the accommodating cavity S2 of the reinforcing part 20 cooperates with the accessories. In this way, the retention ability of the dental orthodontic appliance 100 between the teeth when subjected to force can be enhanced, preventing the dental orthodontic appliance 100 from coming out of the sleeve. Reducing the height of the reinforcing part 20 can avoid excessive interference between the reinforcing part 20 and the interior of the oral cavity or the functional parts 200.

[0063] Since the functional part 200 will exert force on the fixing part 10, the area of ​​the appliance body 101 connected to the fixing part 10 is easy to be separated from the tooth surface, and in serious cases, the entire dental orthodontic appliance 100 may be disengaged. Therefore, in this embodiment, the reinforcing part 20 can be arranged adjacent to the fixing part 10, such as Figure 1 and Figure 2 As shown, the reinforcing portion 20 is disposed on the left and right sides and opposite to the fixing portion 10 .

[0064] In another application scenario of the present invention, combined with Figure 8 and Fig. 9 , taking the dental instrument 100 as an anchor nail guide plate 100 as an example for explanation.

[0065] The functional component 200 may be, for example, an anchoring nail 200 , but is not limited thereto.

[0066] The anchor nail guide 100 includes a guide body 1011 having a cavity S for accommodating teeth and an extension area 1012, wherein the extension area 1012 is an area formed by extending the guide body 1011 toward the gingival area A3, that is, the instrument body 101 at this time includes the connected guide body 1011 and the extension area 1012, and the fixing portion 10 is located in the extension area 1012, specifically, the fixing portion 10 is located on the side of the extension area 1012 away from the gingival area A3.

[0067] The fixing portion 10 has a perforated portion 11, and the insertion end 203 of the anchorage nail 200 is limited to the perforated portion 11. The insertion end 203 is the implantation portion at the lower end of the anchorage nail 200, and the insertion end 203 passes through the perforated portion 11 and is implanted into the gum area A3.

[0068] The extension direction of the perforated portion 11 can be designed according to the required implantation direction of the anchorage nail 200 .

[0069] When the insertion end 203 of the support nail 200 enters the perforated portion 11, the perforated portion 11 can constrain the implantation direction of the support nail 200 so that the support nail 200 is implanted in the gingival area A3 along the extension direction of the perforated portion 11. In this way, the implantation direction of the support nail 200 can be better controlled.

[0070] Optionally, the support nail guide plate 100 also includes a reinforcing portion 20 arranged adjacent to the fixing portion 10, the reinforcing portion 20 protrudes out of the extension area 1012 or the guide plate body 1011 toward the side away from the cavity S, and the reinforcing portion 20 forms an accommodating cavity S2 for accommodating tooth surface accessories, and the height of the reinforcing portion 20 is less than the height of the fixing portion 10.

[0071] Optionally, the reinforcement part 20 is arranged in the guide plate body 1011 area, and accessories can be pre-added on the tooth surface. When the support nail guide plate 100 is worn, the accommodating cavity S2 of the reinforcement part 20 cooperates with the accessories. In this way, the retention ability between the support nail guide plate 100 and the teeth when subjected to force can be enhanced, and the support nail guide plate 100 can be prevented from being decoupled. Reducing the height of the reinforcement part 20 can avoid excessive interference between the reinforcement part 20 and the interior of the oral cavity or the functional parts 200.

[0072] Next, various implementation forms of the fixing portion 10 in different application scenarios are introduced.

[0073] Combination Figures 10 to 15 In a first implementation form, the dental component 300f includes a dental instrument 100f and a functional part 200f, the dental instrument 100f is a dental orthodontic appliance 100f, and the functional part 200f is a lip stopper.

[0074] In a first implementation form, a dental orthodontic appliance 100f includes an appliance body 101f having a cavity S for accommodating teeth and a fixing portion 10f protruding from the appliance body 101f toward a side away from the cavity S, wherein the fixing portion 10f includes a fixing portion body 12f and a perforated portion 11f, and the perforated portion 11f is for inserting an insertion end 203f of a functional part 200f.

[0076] The fixing portion body 12f surrounds and forms a cavity S1 communicating with the cavity S.

[0077] Optionally, the fixing portion body 12f includes a connected peripheral portion 121f and a top portion 122f, the peripheral portion 121f is connected to the appliance body 101f, and the peripheral portion 121f and the top portion 122f are arranged to form a cavity S1.

[0078] The fixing part body 12f is roughly a cap-shaped structure, and the hollow structure in the middle of the fixing part body 12f forms a cavity S1. The fixing part body 12f and the corrector body 101f are integrally formed. The molding process of the fixing part body 12f is simple, and the fixing part body 12f and the corrector body 101f cooperate stably.

[0079] Optionally, the perforated portion 11f includes a first opening 111f penetrating through the fixing portion body 12f, and the first opening 111f is located at the peripheral portion 121f or the top 122f.

[0080] The dental orthodontic appliance 100f further comprises a sleeve 14f having a hole 141f with at least one end being open. The sleeve 14f passes through the first opening 111f and extends to the cavity S1. The fixing portion 10f is exposed at the opening, and the insertion end 203f is inserted into the hole 141f through the opening.

[0081] “A hole 141f with at least one end being open” means that the hole 141f at least passes through one end surface of the sleeve 14f, and the insertion direction of the sleeve 14f is parallel to the extension direction of the hole 141f. After the sleeve 14f passes through the first opening 111f and extends to the cavity S1, the opening of the hole 141f is located on the outside and the arch insertion end 203f is inserted.

[0082] The sleeve 14f is detachably connected to the fixing part 10f, that is, the sleeve 14f can be detachably installed to the fixing part body 12f, and different types of sleeves 14f can be installed to the same fixing part body 12f. By replacing different types of sleeves 14f, different types of functional parts can be easily adapted.

[0083] For example, by replacing the sleeve 14f with different inner diameters, it is convenient to adapt to the arch wire 202f with different diameters.

[0084] Optionally, the perforated portion 11f further includes a second opening 112f penetrating the fixing portion body 12f, and the sleeve 14f sequentially passes through the first opening 111f, the cavity S1 and the second opening 112f, thereby improving the stability of the fit between the sleeve 14f and the fixing portion body 12f.

[0085] The line connecting the first opening 111f and the second opening 112f is parallel to the proximal-distal direction, and the sleeve 14f also extends along the proximal-distal direction.

[0086] Optionally, one end of the sleeve 14f has a step portion 142f protruding in a direction away from the hole 141f, and the fixing portion body 12f includes a stopper 125f arranged around the first opening 111f, and a side surface of the stopper 125f away from the cavity S1 cooperates with the step portion 142f to limit the sleeve 14f from continuing to move toward the cavity S1.

[0087] The side surface of the blocking portion 125f away from the cavity S1 is the proximal surface 1211f of the fixing portion body 12f. The step portion 142f is located on the outside of the cavity S1. The step portion 142f is a flange structure at the end of the sleeve 14f. The step portion 142f and the proximal surface 1211f abut against each other to limit the sleeve 14f from continuing to move in the distal direction. The step portion 142f is arranged around the opening.

[0088] Several specific examples of the first implementation form are introduced below.

[0089] Combination Fig.12 , is a schematic diagram of the first specific example of the cross section of the fixing portion 10f in the direction perpendicular to the buccal-lingual line cooperating with the arch wire 202f.

[0090] In the first specific example, the perforated portion 11f includes only the first opening 111f located on the proximal surface 1211f of the peripheral portion 121f, that is, the other regions of the fixing portion body 12f are closed regions.

[0091] One end of the hole 141f at the sleeve 14f is open, and the other end is a closed end, that is, the hole 141f only penetrates the proximal end surface of the sleeve 14f but does not penetrate the distal end surface of the sleeve 14f.

[0092] The sleeve 14f enters the cavity S1 from the first opening 111f along the proximal-distal direction, and the insertion end 203f of the arch wire 202f is inserted into the hole 141f of the sleeve 14f from the opening of the proximal end surface. When the insertion end 203f abuts against the closed distal end surface of the hole 141f, the arch wire 202f can be stopped.

[0093] Combination Fig.13 , is a schematic diagram of the cross section of the fixing portion 10f of the second specific example in a direction perpendicular to the buccal-lingual line in cooperation with the arch wire 202f.

[0095] Both ends of the hole 141f at the sleeve 14f are open, that is, the hole 141f passes through the proximal end surface and the distal end surface of the sleeve 14f.

[0096] The dental component 300f includes a stop portion 2021f connected to the insertion end 203f, and the stop portion 2021f is a bending area of ​​the arch wire 202f. After the insertion end 203f enters the hole 141f, the stop portion 2021f and the mesial side of the step portion 142f abut against each other to limit the length of the arch wire 202f entering the cavity S1, and the force acting on the arch wire 202f can be transmitted to the fixing portion 10f through the cooperation between the stop portion 2021f and the mesial side of the step portion 142f.

[0097] For other explanations of the second specific example, please refer to other specific examples and will not be repeated here.

[0098] Combination Fig.14 , is a schematic diagram of the third specific example of the cross section of the fixing portion 10f in the direction perpendicular to the buccal-lingual line cooperating with the arch wire 202f.

[0099] The main difference between the third specific example and the second specific example is that the perforated portion 11f of the third specific example includes a first opening 111f located on the proximal surface 1211f of the peripheral portion 121f and a second opening 112f located on the distal surface 1212f, and the line connecting the first opening 111f and the second opening 112f is parallel to the proximal-distal direction, and the sleeve 14f passes through the first opening 111f, the cavity S1 and the second opening 112f in sequence.

[0101] Optionally, the second opening 112f is a through hole. In other specific examples, the second opening 112f may also be a blind hole.

[0102] For other explanations of the third specific example, please refer to other specific examples and will not be repeated here.

[0103] Combination Fig.15 , is a schematic diagram of the fourth specific example of the cross section of the fixing portion 10f in the direction perpendicular to the buccal-lingual side line cooperating with the arch wire 202f.

[0104] The main difference between the fourth specific example and the third specific example is that the stop portion 2021f of the fourth specific example is a block structure sleeved on the arch wire 202f.

[0105] For other explanations of the fourth specific example, please refer to other specific examples and will not be repeated here.

[0107] In a second implementation form, the dental orthodontic appliance 100g includes an appliance body 101g having a cavity S for accommodating teeth and a fixing portion 10g protruding from the appliance body 101g toward a side away from the cavity S, and the fixing portion 10g includes a perforated portion 11g for inserting an insertion end 203g of a functional part 200g.

[0108] The fixing portion 10g is located on the buccal surface A1 or the lingual surface A2 of the appliance body 101g.

[0109] The fixing portion 10g includes a fixing portion body 12g and an embedding portion 13g.

[0110] The fixing portion body 12g surrounds a cavity S1 that communicates with the cavity S. The embedded portion 13g is a preformed component installed in the cavity S1, but is not limited thereto. The embedded portion 13g may also be in other forms. For example, the embedded portion 13g is formed by a material filled in the cavity S1.

[0111] Optionally, the fixing portion body 12g includes a connected peripheral portion 121g and a top portion 122g, the peripheral portion 121g is connected to the orthodontic device body 101g, and the peripheral portion 121g and the top portion 122g are arranged to form a cavity S1.

[0112] The fixing part body 12g is roughly a cap-shaped structure, and the hollow structure in the middle of the fixing part body 12g forms a cavity S1.

After the sleeve 14g passes through the first opening 111g and extends to the channel 131g, the opening of the hole 141g is located on the outside and the arch insertion end 203g is inserted.

[0117] Optionally, the channel 131g is linear, which can facilitate the sleeve 14g to extend into the channel 131, but is not limited thereto.

[0119] The sleeve 14g is detachably connected to the fixing portion 10g, that is, the sleeve 14g can be detachably inserted into the first opening 111g and the channel 131g. Different types of sleeves 14g can be installed on the same fixing portion 10g. By replacing sleeves 14g with different inner diameters, it is convenient to adapt to archwires 202g with different diameters.

[0120] When the embedded portion 13g is formed by a material filled in the cavity S1, the embedded portion 13g can be composed of a resin material, and the sleeve 14g with a required inner diameter can be inserted into the cavity S1 first, and then the embedded portion 13g can be formed by filling the resin.

[0123] Optionally, one end of the sleeve 14g away from the first opening 111g is located in the channel 131g, that is, the sleeve 14g passes through the first opening 111g and extends to the channel 131g, and the sleeve 14g does not extend to the second opening 112g.

[0124] Alternatively, the sleeve 14g extends to the second opening 112g, that is, the sleeve passes through the first opening 111g, the channel 131g and the second opening 112g in sequence.

[0125] Optionally, one end of the sleeve 14g has a step portion 142g protruding in a direction away from the hole 141g, and the fixing portion body 12g includes a stopper portion 125g arranged around the first opening 111g, and a side surface of the stopper portion 125g away from the cavity S1 cooperates with the step portion 142g to limit the movement of the sleeve 14g toward the cavity S1.

[0126] The side surface of the blocking portion 125g away from the cavity S1 is the proximal surface 1211g of the fixing portion body 12g, and the step portion 142g is located on the outside of the cavity S1. The step portion 142g is a flange structure at the end of the sleeve 14g. The step portion 142g and the proximal surface 1211g abut against each other to limit the sleeve 14g from continuing to move in the distal direction. The step portion 142g is arranged around the opening.

[0127] Optionally, a protrusion is formed on the outer wall of the sleeve 14g, and the protrusion and the embedded portion 13g limit each other.
