Attachment Installation Template

[0001] This application claims priority to Chinese patent application No. 202423320571.1, filed on December 31, 2024, entitled "Attachment Installation Template", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of orthodontic technology, and more particularly to an accessory installation template. Background Technology

[0003] During orthodontic treatment, it is often necessary to attach attachments to the tooth surface to assist in the orthodontic process. The attachment installation process can make extensive use of attachment installation templates for positioning and bonding attachments to the teeth.

[0004] Current attachment installation templates consist of a template body that matches the teeth, with an attachment receiving cavity on the template body. When the attachment installation template is worn, the light-cured resin injected into the attachment receiving cavity can adhere to the tooth surface, thus forming an attachment on the tooth surface.

[0038] The present application will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0039] Referring to Figures 1 to 3, this is a schematic diagram of the accessory installation template 100 of the embodiments of this application.

[0040] The attachment installation template 100 includes a template body 10 having a cavity S for accommodating teeth, at least one attachment receiving cavity 11 located on the template body 10, and at least one segment line 12 located on the template body 10.

[0041] Optionally, the accessory receiving cavity 11 may be located on the buccal surface A1 and / or lingual surface A2 of the template body 10.

[0042] Optionally, the attachment installation template 100 corresponds to a full-jaw tooth arrangement, meaning the template body 10 accommodates all maxillary teeth or all mandibular teeth. Alternatively, the attachment installation template 100 corresponds to a partial tooth arrangement, meaning the template body 10 accommodates some maxillary teeth or some mandibular teeth. This embodiment uses an attachment installation template 100 corresponding to a full-jaw tooth arrangement as an example.

[0043] The template body 10 includes a first edge line 101 located on its lip and buccal surface A1 and a second edge line 102 located on its tongue surface A2, with segment lines 12 extending from the first edge line 101 to the second edge line 102.

[0044] Optionally, the labial / buccal side of the teeth includes a first gingival line B1, and the lingual side of the teeth includes a second gingival line B2. When the attachment installation template 100 is worn onto the jaw, the labial / buccal surface A1 of the template body 10 may only cover the tooth area above the first gingival line B1. Alternatively, the labial / buccal surface A1 may simultaneously cover the tooth area above the first gingival line B1 and the gingival area below the first gingival line B1. Alternatively, a portion of the labial / buccal surface A1 may only cover the tooth area above the first gingival line B1, while another portion may simultaneously cover both the tooth area above and the gingival area below the first gingival line B1.

[0045] When the attachment installation template 100 is worn on the jaw, the lingual surface A2 of the template body 10 may only cover the tooth area above the second gingival line B2. Alternatively, the lingual surface A2 may simultaneously cover the tooth area above the second gingival line B2 and the gingival area below the second gingival line B2. Alternatively, a portion of the lingual surface A2 may only cover the tooth area above the second gingival line B2, while another portion may simultaneously cover both the tooth area above and the gingival area below the second gingival line B2.

[0046] In this embodiment, the first edge line 101 corresponds to the first gingival line B1 on the labial / buccal side of the tooth, and the second edge line 102 corresponds to the second gingival line B2 on the lingual side of the tooth. When the accessory installation template 100 is worn on the jaw, the first edge line 101 of the template body 10 is aligned with the first gingival line B1 on the labial / buccal side of the tooth, and the second edge line 102 of the template body 10 is aligned with the second gingival line B2 on the lingual side of the tooth. When the segment line 12 extends from the first edge line 101 to the second edge line 102, the segment line 12 extends from the first edge line 101 through the labial / buccal surface A1, the occlusal surface A3, and the lingual surface A2 of the template body 10 to the second edge line 102.

[0047] The accessory installation template 100 of this embodiment has pre-set segment lines 12, meaning that the accessory installation template 100 already has segment lines 12 before it is worn onto the teeth, and the segment lines 12 can be disconnected without the aid of additional tools. When the segment lines 12 are completely disconnected, the accessory installation template 100 is divided into at least two segments, which facilitates the removal of the accessory installation template 100.

[0048] Figure 3 illustrates an example where the accessory installation template 100 is divided into two mutually disconnected sub-accessory installation templates 100a and 100b by breaking a segment line 12. When removing the accessory installation template 100, the first sub-accessory installation template 100a and the second sub-accessory installation template 100b can be removed separately. Since the first sub-accessory installation template 100a (or the second sub-accessory installation template 100b) has relatively weaker ability to wrap around the teeth, it is easier to remove the first sub-accessory installation template 100a (or the second sub-accessory installation template 100b).

[0049] This embodiment greatly simplifies the user's operation of disconnecting the accessory installation template 100 by setting the segment line 12, thereby reducing the deformation of the accessory installation template 100 caused by the force exerted when the user disconnects it, and improving the convenience of using the accessory installation template 100 and the reliability of accessory installation.

[0050] In this embodiment, the segment line 12 extends from the first edge line 101 to the second edge line 102, meaning that the segment line 12 spans the entire surface of the template body 10. When the segment line 12 is completely broken, the accessory installation template 100 can be divided into completely broken multi-segment structures, further simplifying user operation.

[0051] Optionally, segment line 12 may include a break line and / or a weak connection line.

[0052] The entire segment line 12 is a broken line. Alternatively, the entire segment line 12 is a weakly connected line. Or, a portion of segment line 12 is a broken line and a portion is a weakly connected line.

[0053] "Break line" refers to the segment line 12 completely penetrating the template body 10 in the thickness direction. Taking a segment line 12 as an example, before the segment line 12 is torn open, the accessory installation template 100 already includes a completely broken first sub-accessory installation template 100a and a second sub-accessory installation template 100b, that is, the accessory installation template 100 worn on the jaw consists of the completely broken first sub-accessory installation template 100a and second sub-accessory installation template 100b.

[0054] The accessory installation template 100 is generally made of a polymer material with good toughness (i.e., strong tear resistance). The accessory installation template 100 is difficult to break. The segmented line 12 in the form of a "break line" can directly eliminate the need to break the accessory installation template 100.

[0055] "Weak connection line" refers to a segment line 12 that does not completely penetrate the template body 10 in the thickness direction. Taking a segment line 12 as an example, before the segment line 12 is torn, the first sub-attachment installation template 100a and the second sub-attachment installation template 100b in the attachment installation template 100 are still connected together. The weak connection line is an easy-to-tear line, for example, the user can tear the weak connection line by applying a small force, which is convenient for the user to operate.

[0056] When segment line 12 is a weak connecting line, segment line 12 can be torn off before or after the tooth is fitted. When segment line 12 is torn off before the tooth is fitted, the attachment installation template 100 fitted onto the tooth consists of a completely disconnected first sub-attachment installation template 100a and a second sub-attachment installation template 100b. When segment line 12 is torn off after the tooth is fitted, the attachment installation template 100 fitted onto the tooth consists of a connected first sub-attachment installation template 100a and a second sub-attachment installation template 100b.

[0057] Optionally, the segment line 12 is spaced apart from the accessory receiving cavity 11, meaning that the segment line 12 will not pass through the accessory receiving cavity 11, and the setting of the segment line 12 will not affect the normal use of the accessory receiving cavity 11.

[0058] The segment line 12 may be positioned adjacent to the accessory receiving cavity 11. For example, the segment line 12 and the accessory receiving cavity 11 may be positioned corresponding to the same tooth. Alternatively, the segment line 12 and the accessory receiving cavity 11 may be positioned corresponding to two adjacent teeth, but this is not a limitation.

[0059] After the attachment installation template 100 is worn onto the tooth, an attachment can be formed, for example, by filling the attachment receiving cavity 11 with light-cured resin. The attachment is then bonded to the tooth surface, and the attachment installation template 100 is removed, leaving the attachment on the tooth surface. If the segment line 12 is located adjacent to the attachment receiving cavity 11, force can be applied at the broken segment line 12 to directly lift the attachment receiving cavity 11, facilitating the removal of the attachment receiving cavity 11 from the attachment, thus facilitating the removal of the attachment installation template 100.

[0060] Optionally, continuing with Figures 1 to 3, the template body 10 includes the crown surface P1 of the corresponding tooth T1 and the adjacent tooth area P2 of the corresponding adjacent tooth space T2, and the segment line 12 passes through the crown surface P1.

[0061] The interdental space T2 refers to the area between adjacent teeth T1. The crown surface P1 includes the first crown surface P11 of the labial / buccal side of tooth T1, the second crown surface P12 of the lingual side of tooth T1, and the roof crown surface P13 connecting the first crown surface P11 and the second crown surface P12. The interdental region P2 includes the area between two adjacent first crown surfaces P11, the area between two adjacent second crown surfaces P12, and the area between two adjacent roof crown surfaces P13.

[0062] The morphological undulation of the interdental space T2 is greater than that of tooth T1, and the morphological undulation of the corresponding adjacent tooth region P2 is also greater than that of the crown surface P1.

[0063] Generally, the segment line 12 can be formed by laser cutting the template body 10. The adjacent tooth region P2 has a large degree of morphological undulation, making it difficult for the laser to accurately perform cutting operations there. In contrast, the crown surface P1 has a smaller degree of morphological undulation, facilitating precise laser cutting operations on it. In this embodiment, the segment line 12 passes through the crown surface P1, which, compared to an embodiment where the segment line 12 is entirely within the adjacent tooth region P2, greatly simplifies the laser cutting process and improves laser cutting accuracy.

[0064] Optionally, the segment line 12 is spaced apart from the adjacent tooth region P2, meaning that the segment line 12 does not pass through the adjacent tooth region P2 at all. The segment line 12 extends from the first edge line 101, passing sequentially through the first crown surface P11, the top crown surface P13, and the second crown surface P12, to the second edge line 102. The morphological undulation of the entire segment line 12 is relatively small, which facilitates the formation of the segment line 12 by laser cutting.

[0065] In other embodiments, the segment line 12 may also pass through both the crown surface P1 and the adjacent tooth area P2.

[0066] Optionally, referring to Figure 3, segment 12 is located in the first plane M. Alternatively, referring to Figure 4, segment 12 is a curve located on a different plane.

[0067] Referring to Figure 3, the segment line 12 is located in the first plane M, that is, the segment line 12 is the line segment formed by the intersection of the first plane M and the template body 10.

[0068] Optionally, the first plane M can be perpendicular to the mesiodistal direction. The segment line 12 and the attachment cavity 11 correspond to the same tooth, and the entire segment line 12 is located on the right side of the attachment cavity 11 on that tooth. The segment line 12 extends from the first edge line 101 through the first crown surface P11, the top crown surface P13, and the second crown surface P12 to the second edge line 102. The entire segment line 12 only passes through the crown surface P1 of that tooth, and the segment line 12 located on the first plane M is easier to determine and laser cut.

[0069] In other embodiments, when the segment line 12 is located in the first plane M, the first plane M may not be perpendicular to the mesiodistal direction. For example, the first plane M forms an acute angle with the mesiodistal direction, and the segment line 12 may correspond to one or more teeth.

[0070] Referring to Figure 4, the segment line 12 is a curve located on different surfaces. For example, by selecting multiple target points on the template body 10 and fitting the multiple target points in sequence to form a complete curve, the personalized design of the segment line 12 can be realized.

[0071] The segment line 12 and the accessory receiving cavity 11 are set for the same tooth. The segment line 12 extends from the first edge line 101 through the first crown surface P11, the top crown surface P13 and the second crown surface P12 on the left and above the accessory receiving cavity 11 to the second edge line 102. The entire segment line 12 only passes through the crown surface P1.

[0072] In other embodiments, the segment line 12 may also correspond to multiple teeth.

[0073] Optionally, the location of the segment line 12 can be further explained in conjunction with Figures 5 and 6.

[0074] The template body 10 includes a mounting surface P3 on the labial or buccal side or the lingual side corresponding to a tooth. Taking the mounting surface P3 corresponding to tooth number 3 as an example.

[0075] Mounting surface P3 includes a mesial end P31 and a distal end P32 positioned opposite each other. Mesial end P31 corresponds to the boundary between tooth 3 and tooth 2, and includes a mesial end located on the labial / buccal surface A1 and a mesial end located on the lingual surface A2. Distal end P32 corresponds to the boundary between tooth 3 and tooth 4, and includes a distal end located on the labial / buccal surface A1 and a distal end located on the lingual surface A2.

[0076] Mounting surface P3 is the region located between the mesial end P31 and the distal end P32 of the labial / buccal surface A1. That is, mounting surface P3 includes the first crown surface P11 and the adjacent tooth regions P2 located on the left and right sides of the first crown surface P11. Alternatively, mounting surface P3 is the region located between the mesial end P31 and the distal end P32 of the lingual surface A2. That is, mounting surface P3 includes the second crown surface P12 and the adjacent tooth regions P2 located on the left and right sides of the second crown surface P12. Here, we take the example where mounting surface P3 includes the first crown surface P11 and the adjacent tooth regions P2 located on the left and right sides of the first crown surface P11.

[0077] When the mounting surface P3 has an accessory receiving cavity 11 and the segment line 12 is too close to the accessory receiving cavity 11, the segment line 12 is prone to interfering with the accessory receiving cavity 11, thus affecting the normal use of the accessory receiving cavity 11. When the segment line 12 is too close to the mesial end P31 and distal end P32 of the mounting surface P3 (regardless of whether the mounting surface P3 has an accessory receiving cavity 11), the segment line 12 will enter or approach the adjacent tooth area P2, affecting the laser cutting process of the segment line 12.

[0078] In order to avoid interference between the segment line 12 and the accessory receiving cavity 11 and to avoid affecting the laser cutting process of the segment line 12, an area where the segment line 12 can be set needs to be defined on the mounting surface P3.

[0079] Optionally, in one example, the mounting surface P3 includes mutually spaced non-passable regions N' and passable regions N, thus dividing the entire mounting surface P3 into non-passable regions N' and passable regions N, with segment line 12 located in the passable region N.

[0080] Referring to Figure 6, the shaded area on the mounting surface P3 indicates the impassable area N'.

[0081] The non-passable area N' includes the area of ​​the accessory receiving cavity 11, the first peripheral area N1' surrounding the accessory receiving cavity 11, the second peripheral area N2' connecting the proximal end P31, and the third peripheral area N3' connecting the distal end P32. In the proximal-distal direction, the width G1 of the first peripheral area N1' (including the left and right sides of the accessory receiving cavity 11) ranges from 0.1mm to 1mm, the width G2 of the second peripheral area N2' ranges from 0.1mm to 1mm, and the width G3 of the third peripheral area N3' ranges from 0.1mm to 1mm.

[0082] The widths G1, G2, and G3 can be customized according to factors such as the dimensions of the mounting surface P3 and the dimensions of the accessory receiving cavity 11. The first peripheral region N1' also includes the upper and lower regions located in the accessory receiving cavity 11. The width of the upper and lower regions can also range from 0.1mm to 1mm, but is not limited to this.

[0083] Excluding the shaded area, the mounting surface P3 area is the passable area N, and the segment line 12 can be freely designed in the passable area N.

[0084] Optionally, in another example, referring to Figure 7, when the accessory receiving cavity 11 and the segment line 12 are located on the same mounting surface P3, in the near-far direction, the accessory receiving cavity 11 and the segment line 12 located on the same mounting surface P3 have a first distance D1, the first distance D1 is not less than 0.1mm, and the first distance D1 is the distance between the edge of the accessory receiving cavity 11 near the segment line 12 and the segment line 12.

[0085] In the near-to-far direction, there is a second spacing D2 and a third spacing D3 between the segment line 12 located on the mounting surface P3 and the near-middle end P31 and the far-middle end P32 of the mounting surface P3, respectively. The second spacing D2 is not less than 0.1mm and the third spacing D3 is not less than 0.1mm.

[0086] Optionally, referring to Figures 8 to 10, the segmented line 12 is formed by laser cutting as an example. By adjusting the first parameter of laser cutting, different shapes of the segmented line 12 can be formed, thus adapting to different application scenarios. The first parameter includes, for example, the linear speed of laser cutting, the power of the laser, and the frequency of the laser.

[0087] Different widths W and depths H can be formed by cutting on the template body 10 through different combinations of the first parameters. Different widths W and different depths H can be combined to form segment lines 12 of different shapes. For example, in the extension direction of the segment line 12, different widths W are arranged alternately to form a segment line 12 of a specific shape.

[0088] Generally speaking, increasing the linear speed of laser cutting will reduce the width W and depth H, while increasing the power of the laser will increase the width W and depth H. However, the effect of the laser frequency is affected by the material being cut, the laser model, the light emission principle, etc., and cannot be generalized.

[0089] When segment line 12 is a disconnected line, simply select a suitable first parameter combination to completely disconnect the accessory installation template 100.

[0090] When segment line 12 is a weak connection line, different shapes of segment line 12 can be formed by adjusting the combination of the first parameters.

[0091] Referring to Figures 8 to 10, the segment line 12 includes a weak connecting line, and the same weak connecting line includes a first region 121 and a second region 122. The tear resistance of the first region 121 is not less than the tear resistance of the second region 122.

[0092] "Tear resistance" characterizes the amount of external force required for a certain area to be broken. The greater the tear resistance, the greater the external force required to break it. Tear resistance is related to the material of the template body 10 itself, the width W of the cut, the depth H, and other secondary parameters. Here, we take the example of using the same material for all areas of the template body 10.

[0093] Optionally, the same weak connection line includes a first slot 123 and a second slot 124, wherein the tear resistance of the first slot 123 is not less than the tear resistance of the second slot 124.

[0094] The weak connection line includes a connected slotted area 125 and a closed area 126, with the closed area 126 closer to the cavity S than the slotted area 125. The slotted area 125 includes a first slot 123 and a second slot 124. The slotted area 125 is formed by laser cutting the side of the template body 10 away from the cavity S, and the first slot 123 and the second slot 124 can be obtained by selecting a specific combination of first parameters.

[0095] The first slot 123 has a first width W1 in a direction perpendicular to the extension direction of the segment line 12 and a first depth H1 in the thickness direction. The second slot 124 has a second width W2 in a direction perpendicular to the extension direction of the segment line 12 and a second depth H2 in the thickness direction. The first width W1 is not greater than the second width W2, and / or the first depth H1 is not greater than the second depth H2.

[0096] With all other second parameters being equal, the larger the width W, the lower the tear strength; and the larger the depth H, the lower the tear strength. For ease of explanation, we will take the example of the first slot 123 and the second slot 124 having the same second parameters, but differing only in width W. That is, the first depth H1 is equal to the second depth H2, and the first width W1 is not greater than the second width W2.

[0097] Below are some specific examples of segment lines 12 being all weak connectors.

[0098] In the first specific example, referring to Figure 8, all regions of segment 12 have equal tear resistance, that is, all regions have the same width W and depth H.

[0099] Two regions are arbitrarily selected at segment line 12 as the first region 121 and the second region 122, where the tear resistance of the first region 121 is equal to the tear resistance of the second region 122. For example, the first region 121 includes a first groove 123, the second region 122 includes a second groove 124, the first depth H1 is equal to the second depth H2, and the first width W1 is equal to the second width W2.

[0100] In the second specific example, referring to Figure 9, different regions of segment 12 have different tear resistance.

[0101] Two regions are selected at the same segment line 12 as a first region 121 and a second region 122, where the tear resistance of the first region 121 is greater than that of the second region 122. For example, the first region 121 includes a first groove 123, the second region 122 includes a second groove 124, the first depth H1 is equal to the second depth H2, and the first width W1 is less than the second width W2.

[0102] In the extension direction of the segment line 12, the first region 121 has a first length L1 (i.e., the first slot 123 has a first length L1), and the second region 122 has a second length L2 (i.e., the second slot 124 has a second length L2). The first region 121 and the second region 122 can be alternately arranged in the extension direction of the segment line 12, so that different regions of the segment line 12 have different tear resistance.

[0103] The first length L1 and the second length L2 can be determined according to actual needs. This specific example provides a segmented line 12 with alternating widths, and a section with a narrower cutting width W is set at intervals to increase the difficulty of breaking in that section, which can avoid accidental breakage caused by accidental external force or unintended operation.

[0104] Optionally, the first region 121 is connected to the first edge line 101, and the second region 122 is located away from the first edge line 101 relative to the first region 121. And / or the first region 121 is connected to the second edge line 102, and the second region 122 is located away from the second edge line 102 relative to the first region 121.

[0105] Taking a first region 121 connecting a first edge line 101 and a second edge line 102, and a second region 122 located in the middle of the segment line 12 and connecting the two first regions 121 on both sides as an example. That is, in the extension direction of the segment line 12, the segment line 12 includes a first region 121, a second region 122 and a first region 121 connected in sequence, and the first length L1 of the first region 121 is, for example, approximately 20 mm.

[0106] The first region 121, located at the first edge line 101 and the second edge line 102 of the segment line 12, has a higher tear resistance, while the second region 122, located in the middle of the segment line 12, has a lower tear resistance. On the one hand, the first region 121, with its higher tear resistance, can prevent the segment line 12 from breaking accidentally. On the other hand, after the first region 121 is broken by applying a small force, the second region 122 is easier to break, making the entire breaking process smoother.

[0107] In other specific examples, segment 12 may also include a third region with a third width, etc.

[0108] In the third specific example, referring to Figure 10, different regions of the segment line 12 have different tear resistance.

[0109] Two regions are selected at the same segment line 12 as the first region 121 and the second region 122, with the tear resistance of the first region 121 being greater than that of the second region 122.

[0110] For example, the first region 121 includes alternating first slots 123 and second slots 124. In the extension direction of the segment line 12, the first slot 123 has a first length L1, the second slot 124 has a second length L2, and the first length L1 and the second length L2 are in a first length ratio.

[0111] The second region 122 includes alternating first slots 123 and second slots 124. The first slot 123 has a first length L1, and the second slot 124 has a second length L2. The ratio between the first length L1 and the second length L2 is a second length ratio, and the first length ratio is greater than the second length ratio.

[0112] Here, taking as an example two first slots 123 in the first region 121 and the second region 122 having the same first width W1 and first depth H1, and two second slots 124 in the first region 121 and the second region 122 having the same second width W2 and second depth H2. The two first slots 123 in the first region 121 and the second region 122 have different first lengths L1, and / or the two second slots 124 in the first region 121 and the second region 122 have different second lengths L2. By specifically designing the lengths so that the first length ratio is greater than the second length ratio, the proportion of the first slots 123 in the first region 121 is higher, which can make the tear resistance of the first region 121 greater than that of the second region 122.

[0113] For example, the first length ratio can be greater than 1, and the second length ratio can be in the range of 0-1, which can be selected according to specific needs.

[0114] Optionally, the first region 121 is connected to the first edge line 101, and the second region 122 is located away from the first edge line 101 relative to the first region 121. And / or the first region 121 is connected to the second edge line 102, and the second region 122 is located away from the second edge line 102 relative to the first region 121.

[0115] Taking a first region 121 connecting a first edge line 101 and a second edge line 102, and a second region 122 located in the middle of the segment line 12 and connecting the two first regions 121 on both sides as an example. That is, in the extension direction of the segment line 12, the segment line 12 includes a first region 121, a second region 122 and a first region 121 connected in sequence, and the first length L1 of the first region 121 is, for example, approximately 20 mm.

[0116] The first region 121, located at the first edge line 101 and the second edge line 102 of the segment line 12, has a higher tear resistance, while the second region 122, located in the middle of the segment line 12, has a lower tear resistance. On the one hand, the first region 121, with its higher tear resistance, can prevent the segment line 12 from breaking accidentally. On the other hand, after the first region 121 is broken by applying a small force, the second region 122 is easier to break, making the entire breaking process smoother.

[0117] Optionally, referring to Figures 11 and 12, in another embodiment, the accessory mounting template 100 further includes a handle portion 20 protruding from the first edge line 101, with the segment line 12 extending to the edge of the handle portion 20. And / or the accessory mounting template 100 also includes a handle portion 20 protruding from the second edge line 102, with the segment line 12 extending to the edge of the handle portion 20. Figures 11 and 12 illustrate the handle portion 20 protruding from the first edge line 101 as an example.

[0118] The handle 20 can be integrally formed with the template body 10, but is not limited thereto. When the first edge line 101 corresponds to the first gingival line B1, the handle 20 can be regarded as the part of the template body 10 extending to the gingival area. The handle 20 can be easily pinched to break the segment line 12 or to remove the attachment and install the template 100.

[0119] "The segment line 12 extends to the edge of the handle 20" means that when the segment line 12 is broken, the handle 20 is also broken, and the first sub-accessory mounting template 100a and the second sub-accessory mounting template 100b will not be connected together with the help of the handle 20.

[0120] Referring to Figure 11, the handle 20 is symmetrically arranged on both sides of the segment line 12. The handle 20 connects the first sub-accessory mounting template 100a and the second sub-accessory mounting template 100b. The segment line 12 extends from the middle of the handle 20 to the bottom edge of the handle 20.

[0121] Referring to Figure 12, the handle 20 is only located on one side of the segment line 12, and the handle 20 is only connected to the first sub-accessory mounting template 100a. The segment line 12 extends from the right side of the handle 20 to the bottom edge of the handle 20.

[0122] In summary, the attachment installation template 100 of this application has pre-set segment lines 12, meaning that the attachment installation template 100 already has segment lines 12 before being worn onto the teeth, and the segment lines 12 can be disconnected without the aid of additional tools. When the segment lines 12 are completely disconnected, the attachment installation template 100 is divided into at least two segments, which facilitates the removal of the attachment installation template 100.

[0123] By setting segment lines 12, this application can greatly simplify the user's operation of disconnecting the accessory installation template 100, thereby reducing the deformation of the accessory installation template 100 caused by the force exerted when the user disconnects it, and improving the ease of use of the accessory installation template 100 and the reliability of accessory installation.

[0124] The segment line 12 of this application extends from the first edge line 101 to the second edge line 102, that is, the segment line 12 spans the entire surface of the template body 10. When the segment line 12 is completely broken, the accessory installation template 100 can be divided into a completely broken multi-segment structure, further simplifying user operation.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0126] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
