[0049] 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.

[0050] Combination Figures 1 to 8, which is a schematic diagram of a dental apparatus 200 according to an embodiment of the present invention.

[0051] The dental instrument 200 comprises an interface accessory 10 and a first functional accessory 20 mounted on the interface accessory 10 , wherein the interface accessory 10 is configured to provide at least two working modes for the mounted first functional accessory 20 .

[0052] Here, "at least two working forms" means that under different assembly conditions, the first functional accessory 20 can form at least two working forms. That is to say, when the assembly forms of the interface accessory 10 and the first functional accessory 20 are different, the working states displayed by the first functional accessory 20 are different. For example, the position, force direction, force intensity, etc. of the first functional accessory 20 itself are different, thereby adapting to different correction needs.

[0053] This embodiment can improve the assembly freedom of the first functional accessory 20 by providing an interface accessory 10. Specifically, the interface accessory 10 is a universal interface accessory. By changing the assembly form, the interface accessory 10 provides at least two working forms for the first functional accessory 20. When faced with different correction needs, the first functional accessory 20 can achieve different working forms by changing the assembly form with the interface accessory 10 to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0054] In this embodiment, the two working forms correspond to the same first functional accessory 20, that is, the correction needs can be met by changing the working form of the first functional accessory 20 without changing the type of functional accessory, which can greatly improve the versatility of the first functional accessory 20.

[0055] In this embodiment, the interface accessory 10 is mounted to the mounting surface 101 .

[0056] Here, the mounting surface may be a tooth maxillary surface, or the dental appliance 200 includes an invisible brace 100 having a mounting surface 101 . The invisible brace 100 refers to a shell-shaped dental appliance having a cavity for accommodating teeth.

[0057] In this embodiment, the interface accessory 10 is installed on the mounting surface 101 of the invisible braces 100 as an example. The interface accessory 10 is fixedly connected to the mounting surface 101 , or the interface accessory 10 is detachably connected to the mounting surface 101 .

[0058] Specifically, in this embodiment, the mounting surface 101 is located on the buccal surface A1 of the invisible braces 100, and the mounting surface 101 is a flat plane. The interface accessory 10 is bonded to the mounting surface 101, but this is not limited to it. The mounting surface 101 may also be located on the lingual surface A3 of the invisible braces 100, etc.

[0059] In this embodiment, combined with Figure 8 The dental instrument 200 further includes a second functional accessory 30 , and the interface accessory 10 includes a first interface 102 and a second interface 103 . The first interface 102 is used to assemble the first functional accessory 20 , and the second interface 103 is used to assemble the second functional accessory 30 .

[0060] That is to say, the interface accessory 10 can be selectively connected to at least two types of functional accessories, which further improves the versatility of the interface accessory 10, and different types of functional accessories can adapt to different application scenarios, which can improve the overall versatility of the dental instrument 200. In addition, different types of functional accessories can be used in combination to improve the correction efficiency.

[0061] The first interface 102 and the second interface 103 are respectively at least one of a limiting surface, a limiting notch, and a limiting portion, but are not limited thereto.

[0062] The first functional accessory 20 and the second functional accessory 30 are respectively at least one of a traction hook, an archwire, a rubber band, and a jaw pad, but are not limited thereto.

[0063] Here, archwires refer to products with archwires, such as products formed by the combination of an archwire and an extraoral bow, a lip stopper, a palate bead trainer, etc.

[0064] In this embodiment, continue to combine Figures 1 to 8 The interface accessory 10 is configured to change its relative position with the first functional accessory 20 to provide at least two working modes for the first functional accessory 20 .

[0065] That is, when the relative position between the interface accessory 10 and the first functional accessory 20 changes, the working form of the first functional accessory 20 also changes.

[0066] Here, the first functional accessories 20 in different working forms correspond to the same correction step or different correction steps. For example, in the same correction step, the position of the first functional accessory 20 relative to the interface accessory 10 can be adjusted at different time periods to adjust the correction effect. Alternatively, in different correction steps, the position of the first functional accessory 20 relative to the interface accessory 10 can be adjusted to match the correction requirements of different correction steps.

[0067] In a specific example, the interface accessory 10 is configured to change its relative position with the first functional accessory 20 according to different correction steps.

[0068] At this time, different correction steps can use the same interface accessory 10 and first functional accessory 20, which can greatly improve the versatility of the interface accessory 10 and the first functional accessory 20.

[0069] It is understandable that when this type of first functional accessory 20 cannot meet the correction needs, while changing the relative position of the interface accessory 10 and the first functional accessory 20, the type of the first functional accessory 20 can also be changed to adapt to more application scenarios.

[0070] In this embodiment, the relative position of the interface accessory 10 and the first functional accessory 20 includes at least one of a first relative position in the first direction B1, a second relative position in the second direction B2, a third relative position in the third direction B3, and a relative angle in the first plane C1, wherein the first direction B1 is perpendicular to the buccal surface A1, the second direction B2 is perpendicular to the occlusal surface A2, the third direction B3 is the mesiodistal direction, and the first plane C1 is parallel to the buccal surface A1.

[0071] That is to say, the relative position of the interface accessory 10 and the first functional accessory 20 can be adjusted in the up and down, left and right, front and back directions, or the relative position of the interface accessory 10 and the first functional accessory 20 refers to the relative angle between the two in the first plane C1, and the relative position of the interface accessory 10 and the first functional accessory 20 is adjusted by rotating the first functional accessory 20 in the first plane C1.

[0072] In a specific example, the first functional accessory 20 is a traction hook, which includes a base 201 and a hook 202 connected to each other. The base 201 is assembled on the interface accessory 10 , and the hook 202 extends in a direction away from the base 201 .

[0073] The interface accessory 10 includes a first limiting surface 11 (i.e., the first interface 102 includes the first limiting surface 11), the first functional accessory 20 includes a second limiting surface 21 (i.e., the base 201 includes the second limiting surface 21), and the first limiting surface 11 is configured to be in different mating positions with the second limiting surface 21 to provide at least two working forms for the first functional accessory 20.

[0074] In other words, when the first limiting surface 11 and the second limiting surface 21 are in different matching positions, the interface accessory 10 and the first functional accessory 20 form different relative angles (combined with Figure 3 and Figure 4 ), or, when the base 201 and the interface accessory 10 are in different assembly positions, the hook 202 has different extension directions so that the first functional accessory 20 has at least two working forms.

[0075] It can be understood that when the first functional accessory 20 is rotated, the matching position of the second limiting surface 21 and the first limiting surface 11 will change, thereby causing the relative angle between the interface accessory 10 and the first functional accessory 20 to change, and the extension direction of the hook 202 in the first functional accessory 20 changes, so that the first functional accessory 20 produces a different working form.

[0076] Specific, combined Figure 3 When the first limiting surface 11 and the second limiting surface 21 are in the first matching position, the first functional accessory 20 extends downward, that is, the hook portion 202 extends downward, and the relative angle between the interface accessory 10 and the first functional accessory 20 is defined as 0° at this time.

[0077] Combination Figure 4 After the first functional accessory 20 is rotated, the first limiting surface 11 and the second limiting surface 21 are in the second matching position, and the first functional accessory 20 extends toward the lower right corner, that is, the hook 202 extends toward the lower right corner. At this time, the relative angle between the interface accessory 10 and the first functional accessory 20 is defined as 30°, that is, the first functional accessory 20 is rotated 30° relative to the interface accessory 10.

[0078] It can be seen that when the matching position between the first limiting surface 11 and the second limiting surface 21 changes, the relative angle between the interface accessory 10 and the first functional accessory 20 also changes, thereby changing the extension direction of the hook 202. The hook 202 with different extension directions can adapt to different traction forces to form different working forms.

[0079] In this embodiment, the first limiting surface 11 is the outer surface of the interface accessory 10, the first functional accessory 20 includes a first through hole 203, and the second limiting surface 21 is the inner surface of the first through hole 203. The second limiting surface 21 is arranged around the outer side of the first limiting surface 11 and produces different matching positions with the first limiting surface 11. In other words, the first functional accessory 20 and the interface accessory 10 are in a socketed matching manner, and different working forms can be provided for the first functional accessory 20 through different socketing angles.

[0080] Here, the first limiting surface 11 includes a plane or a curved surface. In this embodiment, the first limiting surface 11 is formed by splicing six planes as an example, and the cross-section of the first limiting surface 11 is a hexagon, but it is not limited to this. The cross-section of the first limiting surface 11 can also be other polygons, or the first limiting surface 11 is formed by splicing multiple curved surfaces, or the first limiting surface 11 is formed by splicing curved surfaces and planes.

[0081] In addition to the adjustment of the relative angle between the interface accessory 10 and the first functional accessory 20 as described above, in other embodiments, the adjustment of other relative positions of the interface accessory 10 and the first functional accessory 20 may also be involved. For example, one of the interface accessory 10 and the first functional accessory 20 includes a mating portion, and the other includes a plurality of locking portions, and the mating portion is mated to different locking portions to change at least one of the first relative position, the second relative position, and the third relative position.

[0082] Continue to combine Figures 1 to 8In this embodiment, the dental instrument 200 further includes a limiting accessory, which is used to limit the relative movement between the interface accessory 10 and the first functional accessory 20 in the first plane C1 and the first direction B1.

[0083] That is to say, after the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the relative movement of the first functional accessory 20 and the interface accessory 10 in the first plane C1 and the first direction B1 is achieved through the limiting accessory, that is, the relative stillness of the first functional accessory 20 and the interface accessory 10 is achieved.

[0084] The limiting structure includes the aforementioned first limiting surface 11 located on the interface accessory 10 and the second limiting surface 21 located on the first functional accessory 20. The first limiting surface 11 and the second limiting surface 21 cooperate with each other to limit the relative movement of the interface accessory 10 and the first functional accessory 20 in the first plane C1.

[0085] As mentioned above, the first limiting surface 11 includes a plane or an arc surface. When the second limiting surface 21 is matched to the first limiting surface 11, at least part of the first limiting surface 11 and the second limiting surface 21 abut against each other to limit certain relative movements between the first functional accessory 20 and the interface accessory 10.

[0086] Specifically, after the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the first limiting surface 11 and the second limiting surface 21 can limit the relative rotation and relative movement of the interface accessory 10 and the first functional accessory 20 in the first plane C1.

[0087] The limiting accessory further includes a positioning portion and a positioning surface located on the first functional accessory 20 . The positioning portion and the positioning surface cooperate with each other to limit the relative movement of the interface accessory 10 and the first functional accessory 20 in the first direction B1 .

[0088] Several embodiments of the dental apparatus 200 are described below.

[0089] Combination Figures 1 to 8 , which is a schematic diagram of a dental apparatus 200 according to a first embodiment.

[0090] In the first embodiment, the dental apparatus 200 includes an interface accessory 10 fixedly connected to the invisible braces 100 and a first functional accessory 20 assembled on the interface accessory 10 , and the first functional accessory 20 is taken as a traction hook as an example.

[0091] The outer side surface of the interface accessory 10 forms a first limiting surface 11 with a hexagonal cross-section. The first functional accessory 20 includes a first through hole 203. The inner surface of the first through hole 203 forms a second limiting surface 21 with a hexagonal cross-section. The first limiting surface 11 is completely matched with the second limiting surface 21.

[0092] When the first limiting surface 11 and the second limiting surface 21 are in different mating positions, the interface accessory 10 and the first functional accessory 20 form different relative angles so that the first functional accessory 20 has multiple working forms, that is, the hook portion 202 of the first functional accessory 20 can form different extension directions to provide different forms of traction.

[0093] After the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the first functional accessory 20 is sleeved on the outer side surface of the interface accessory 10 to limit the relative movement between the interface accessory 10 and the first functional accessory 20 in the first plane C1. Specifically, the first limiting surface 11 and the second limiting surface 21 are completely matched to limit the relative rotation and relative movement between the interface accessory 10 and the first functional accessory 20 in the first plane C1.

[0094] The positioning surface is a front surface 204 of the first functional accessory 20 that surrounds the interface accessory 10 and is away from the mounting surface 101 .

[0095] The positioning portion is a latch portion 40, and the interface accessory 10 has a second through hole 104. The latch portion 40 passes through the second through hole 104 and abuts against the front surface 204, thereby limiting the first functional accessory 20 between the mounting surface 101 and the latch portion 40. In this way, the relative movement between the interface accessory 10 and the first functional accessory 20 in the first direction B1 can be limited.

[0096] At this time, the first functional accessory 20 is completely fixed to the interface accessory 10, and the first functional accessory 20 can provide stable traction.

[0097] Here, the second through hole 104 includes a central through hole 1041 and two edge through holes 1042 that are interconnected. The latch portion 40 is a component independent of the interface accessory 10 and the first functional accessory 20 . The latch portion 40 has two elastic walls 41 that are oppositely arranged and have latches 411 .

[0098] After the first functional accessory 20 is sleeved onto the outside of the interface accessory 10, the second through hole 104 is exposed, and the latch portion 40 is initially inserted into the middle through hole 1041. The two elastic walls 41 are deformed toward the middle so that the latch portion 40 can enter the middle through hole 1041. Then, the two elastic walls 41 are reset to drive the two latches 411 to enter the two edge through holes 1042 respectively, thereby achieving mutual fixation between the latch portion 40 and the interface accessory 10. At the same time, after the latch portion 40 passes through the second through hole 104, the two ends of the latch portion 40 protruding out of the interface accessory 10 just abut against the front surface 204 of the first functional accessory 20.

[0099] In addition, the two edge through holes 1042 are exposed outward to form the second interface 103 as described above. The second interface 103 is exposed outside the first functional accessory 20. The second interface 103 can be used to assemble the second functional accessory 30. Here, the second functional accessory 30 is an archwire as an example.

[0100] Of course, in other implementations, the second interface 103 may also be formed in other areas or in other forms.

[0101] It should be noted that in other embodiments, a through hole can be formed on the first functional accessory 20 and the latch portion 40 can pass through the first functional accessory 20 and the interface accessory 10 at the same time. In this way, the thickness of the entire dental instrument 200 can be reduced and the first functional accessory 20 can be further fixed.

[0102] Combination Figures 9 to 12 , is a schematic diagram of a dental apparatus 200a according to a second embodiment. For ease of description, the same or similar components in different embodiments are numbered the same or similarly, hereinafter the same.

[0103] In the second embodiment, the dental apparatus 200a includes an interface accessory 10a fixedly connected to the invisible braces 100a and a first functional accessory 20a assembled on the interface accessory 10a. For example, the first functional accessory 20a is a traction hook.

[0104] The outer side surface of the interface accessory 10a forms a first limiting surface 11a with a hexagonal cross section. The first functional accessory 20a includes a first through hole 203a. The inner surface of the first through hole 203a forms a second limiting surface 21a with a hexagonal cross section. The first limiting surface 11a is completely matched with the second limiting surface 21a.

[0105] When the first limiting surface 11a and the second limiting surface 21a are in different mating positions, the interface accessory 10a and the first functional accessory 20a form different relative angles so that the first functional accessory 20a has multiple working forms, that is, the hook portion of the first functional accessory 20a can form different extension directions to provide different forms of traction.

[0106] After the first functional accessory 20a is assembled to the interface accessory 10a according to the required working form, the first functional accessory 20a is sleeved on the outer side surface of the interface accessory 10a to limit the relative movement of the interface accessory 10a and the first functional accessory 20a in the first plane C1. Specifically, the first limiting surface 11a and the second limiting surface 21a are completely matched to limit the relative rotation and relative movement of the interface accessory 10a and the first functional accessory 20a in the first plane C1.

[0107] The positioning surface is a front surface 204a of the first functional accessory 20a surrounding the interface accessory 10a and away from the mounting surface 101a.

[0108] The positioning portion is a hook 50a located on the interface accessory 10a, and the hook 50a abuts against the front surface 204a, thereby limiting the first functional accessory 20a between the installation surface 101a and the hook 50a. In this way, the relative movement between the interface accessory 10a and the first functional accessory 20a in the first direction B1 can be limited.

[0109] At this time, the first functional accessory 20a is completely fixed to the interface accessory 10a, and the first functional accessory 20a can provide stable traction.

[0110] Here, two oppositely arranged recessed portions 105a are formed on the interface accessory 10a, and two hooks 50a are respectively arranged in the two recessed portions 105a. The hooks 50a can be deformed in the recessed portions 105a, and the undeformed hooks 50a protrude out of the outer side surface of the interface accessory 10a. The hooks 50a can be integrally formed with the interface accessory 10a.

[0111] When the first functional accessory 20a is in the process of being sleeved onto the outside of the interface accessory 10a, the two hooks 50a are squeezed so that the first functional accessory 20a can smoothly pass through the hooks 50a and be assembled onto the interface accessory 10a. Then, the two hooks 50a are reset so that the hooks 50a just abut the front surface 204a of the first functional accessory 20a.

[0112] In addition, combined Fig.12 The second interface 103a as mentioned above is also formed on the outer surface of the interface accessory 10a. The second interface 103a can be used to assemble the second functional accessory 30a. Here, the second functional accessory 30a is taken as an archwire as an example.

[0113] It should be noted that after the first functional accessory 20a is assembled, the second interface 103a can be exposed on the outside of the first functional accessory 20a. In this way, the interface accessory 10a can be equipped with the first functional accessory 20a and the second functional accessory 30a at the same time. Alternatively, after the first functional accessory 20a is assembled, the second interface 103a is blocked by the first functional accessory 20a. At this time, the first functional accessory 20a or the second functional accessory 30a can be selectively assembled.

[0114] Combination Figures 13 to 18 , which is a schematic diagram of a dental apparatus 200b according to a third embodiment.

[0115] In the third embodiment, the dental apparatus 200b includes an interface accessory 10b fixedly connected to the invisible braces 100b and a first functional accessory 20b assembled on the interface accessory 10b. The first functional accessory 20b is exemplified by a traction hook.

[0116] The outer side surface of the interface attachment 10b forms a first limiting surface 11b with a hexagonal cross section.

[0117] The first functional accessory 20b includes a first part 205b and a second part 206b connected to each other. The first part 205b is sleeved on the outer side of the interface accessory 10b. The inner surface of the first part 205b forms a second limiting surface 21b. The first limiting surface 11b partially matches the second limiting surface 21b.

[0118] Here, "partial matching of the first limiting surface 11b and the second limiting surface 21b" means that when the second limiting surface 21b is matched to the first limiting surface 11b, the second limiting surface 21b only covers a partial area of ​​the first limiting surface 11b, and the first limiting surface 11b and the second limiting surface 21b partially match to limit the relative rotation of the interface accessory 10b and the first functional accessory 20b in the first plane C1 and the relative movement in partial directions.

[0119] When the first limiting surface 11b and the second limiting surface 21b are in different mating positions, the interface accessory 10b and the first functional accessory 20b form different relative angles so that the first functional accessory 20b has multiple working forms, that is, the hook portion of the first functional accessory 20b can form different extension directions to provide different forms of traction.

[0120] A notch 2061b is formed in the second portion 206b of the first functional attachment 20b.

[0121] The positioning portion is a traction buckle 60b located on a side of the interface accessory 10b away from the mounting surface 101b.

[0122] The positioning surface is a front surface 204b of the second portion 206b surrounding the notch 2061b and away from the mounting surface 101b.

[0123] After the first functional accessory 20b is assembled to the interface accessory 10b according to the required working form, the first part 205b is sleeved on the outer side surface of the interface accessory 10b and the notch 2061b and the traction buckle 60b cooperate with each other to limit the relative movement of the interface accessory 10b and the first functional accessory 20b in the first plane C1. At the same time, the traction buckle 60b abuts the front surface 204b to limit the first functional accessory 20b between the accessory interface 10b and the traction buckle 60b. In this way, the relative movement of the interface accessory 10b and the first functional accessory 20b in the first direction B1 can be limited.

[0124] At this time, the first functional accessory 20b is completely fixed to the interface accessory 10b, and the first functional accessory 20b can provide stable traction.

[0125] Combination Fig.17The traction buckle 60b can be used to assemble the second functional accessory 30b. Here, the second functional accessory 30b is taken as a rubber band as an example.

[0126] In addition, combined Fig.18 The second interface 103b as mentioned above is also formed on the outer surface of the interface accessory 10b. The second interface 103b can be used to assemble the second functional accessory 30b. Here, the second functional accessory 30b is taken as an archwire as an example.

[0127] It should be noted that after the first functional accessory 20b is assembled, the second interface 103b can be exposed on the outside of the first functional accessory 20b. In this way, the interface accessory 10b can be equipped with the first functional accessory 20b and the second functional accessory 30b at the same time. Alternatively, after the first functional accessory 20b is assembled, the second interface 103b is blocked by the first functional accessory 20b. At this time, the first functional accessory 20b or the second functional accessory 30b can be selectively assembled.

[0128] Combination Fig.19 and Fig. 20 , which is a schematic diagram of a dental instrument 200c according to a fourth embodiment.

[0129] The main difference between the fourth embodiment and the third embodiment is that one of the interface accessory 10c and the first functional accessory 20c includes a mating portion, and the other includes a plurality of latching portions, and the mating portion is mated to different latching portions to change the second relative position or the third relative position.

[0130] Specifically, the mating portion is a traction buckle 60c located on the interface accessory 10c, and the multiple locking portions are a notch 2061c located on the second part 206c of the first functional accessory 20c. Here, the notch 2061c includes multiple connected limiting holes 2061c'. When the traction buckle 60c is matched to different limiting holes 2061c', the second relative position of the interface accessory 10c and the first functional accessory 20c in the second direction B2 or the third relative position in the third direction B3 changes. In this way, multi-directional adjustment of the first functional accessory 20c can be achieved.

[0131] Combination Figure 21 to Figure 29 , is a schematic diagram of a dental instrument 200d according to a fifth embodiment.

[0132] The dental device 200d comprises an interface attachment 10d fixedly connected to a mounting surface 101d of an invisible brace 100d and a first functional attachment 20d assembled on the interface attachment 10d. The first functional attachment 20d is taken as a jaw pad as an example.

[0133] The interface accessory 10d is a traction buckle 60d fixedly connected to the mounting surface 101d, and the first functional accessory 20d includes a plurality of holes 207d interconnected with each other. When the traction buckle 60d is fitted to different holes 207d, the interface accessory 10d and the first functional accessory 20d form different relative positions, so that the first functional accessory 20d has multiple working forms, that is, the jaw pad 20d can be adjusted to different positions.

[0134] For example, combined with Fig.26 When the plurality of holes 207d are arranged along the third direction B3, the position of the jaw pad 20d in the mesiodistal direction can be adjusted.

[0135] Combination Fig. 27 When the plurality of holes 207d are arranged along the second direction B2, the height of the jaw pad 20d can be adjusted.

[0136] Combination Fig.28 and Fig.29 When the plurality of holes 207d are arranged along the second direction B2 and the third direction B3 at the same time or the plurality of holes 207d are arranged along the angle between the second direction B2 and the third direction B3, the position and height of the jaw pad 20d in the mesiodistal direction can be adjusted at the same time.

[0137] In addition, the traction buckle 60d can be set on the buccal surface A1 and the lingual surface A3 of the invisible braces 100d at the same time to fix the arched jaw pad 20d. Multiple traction buckles 60d can be set on one side of the invisible braces 100d, and the multiple traction buckles 60d are all matched with the holes 207d to improve the stability of the jaw pad 20d assembly.

[0138] In summary, the present invention can improve the assembly freedom of the first functional accessory 20 by providing an interface accessory 10. Specifically, the interface accessory 10 is a universal interface accessory. By changing the assembly form, the interface accessory 10 provides at least two working forms for the first functional accessory 20. When faced with different correction needs, the first functional accessory 20 can achieve different working forms by changing the assembly form with the interface accessory 10 to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0139] In addition, the present invention can achieve complete fixation between the interface accessory 10 and the first functional accessory 20 through different forms of limiting accessories, so that the first functional accessory 20 can provide a stable correction effect.
