Considering the depth of occlusion of the teeth of different patients and the required strength of the plywood, the thickness of the digital three-dimensional model of the plywood is designed to be 1.5-10 mm, and the depth of the biting dental impression on the digital three-dimensional model of the plywood is 0.5-3 mm, so that the digital three-dimensional model of the plywood can cover the incisor edge and the palatoglossal side of part or all of the incisors and/or the mesial-distal inclined edge and the palatoglossal side of part or all of the cuspids and/or the occlusal surface and the palatoglossal side of part or all of the posterior teeth and extend to the incisor edge, the mesial-distal inclined edge and the buccal side ridge of the posterior teeth.

In order to achieve the function of guiding the brackets to be bonded in place in the mesial-distal direction, the mesial surface of each of the digital three-dimensional models of the marking blocks should be matched with the mesial surface of the digital three-dimensional model of the bracket of the corresponding tooth or dentition, and the distal surface thereof should be matched with the distal surface of the digital three-dimensional model of the bracket of the corresponding tooth or dentition and parallel to each other. For realizing the matching of the mesial surface of the digital three-dimensional model of the marking block and the mesial surface of the digital three-dimensional model of the corresponding tooth or tooth column bracket, a plane tangential to the mesial surface of the mesial bracket wing of the digital three-dimensional model of each tooth bracket (called as a bracket wing mesial virtual plane) is constructed, and the plane is directly used as the mesial surface of the digital three-dimensional model of the marking block. For realizing the matching of the distal surface of the digital three-dimensional model of the marking block and the distal surface of the digital three-dimensional model of the bracket, a plane tangential to the distal surface of the distal bracket wing of the digital three-dimensional model of each tooth bracket (called as a distal virtual plane of the bracket wing) is constructed in the distal center of the bracket wing, and the plane is directly used as the distal surface of the digital three-dimensional model of the marking block.
In order to realize that the marking blocks are contacted with the bracket to guide the marking blocks to be positioned vertically and connected with the plywood through the connecting blocks, the gingival square end face of each marking block digital three-dimensional model is matched with the square end face of the bracket digital three-dimensional model corresponding to the teeth or the dentition, and the square end face is flush with the nonfunctional plane of the plywood. For matching the gingival square end face of the digital three-dimensional model of the marking block with the square end face of the digital three-dimensional model of the bracket corresponding to each tooth, constructing a plane (called a bracket wing square virtual plane) tangent to the square of the wing of the square Fang Tuocao corresponding to the digital three-dimensional model of each tooth, and directly taking the plane as the gingival square end face of the digital three-dimensional model of the marking block. For realizing that the combined side end face of the digital three-dimensional model of the marking block is flush with the non-functional plane of the plywood, a virtual plane (called as a virtual plane of the non-functional plane of the plywood) overlapped with the non-functional plane of the digital three-dimensional model of the plywood is constructed, and the plane is directly used as a combination Fang Duanmian of the digital three-dimensional model of the marking block. Because the positions of the bracket digital three-dimensional models are different, the bracket wing square virtual plane and the plywood nonfunctional virtual plane may be parallel or not parallel, and the final marking block digital three-dimensional model is designed to be rectangular or inverted trapezoid turned by 90 degrees.
In order to ensure the guiding function and strength of the digital three-dimensional model of the marking blocks, the length of each digital three-dimensional model of the marking blocks is designed to be 2-10mm, and the thickness of each digital three-dimensional model of the marking blocks is designed to be 1-2 mm. Because of the difference in width of the digital three-dimensional model of different dental brackets, the width of the digital three-dimensional model of the marking block matched with the digital three-dimensional model is designed to be 1.5-7mm.
To achieve a block-guided bracket labial-lingual palate orientation, each block-digitized three-dimensional model labial side should be matched to the corresponding bracket digitized three-dimensional model labial side of the tooth or dentition. For realizing the matching of the labial side of the digital three-dimensional model of the marking block and the labial side of the digital three-dimensional model of the bracket, a plane (called a virtual plane of the labial side of the bracket) tangent to the labial side of the bracket corresponding to each tooth bracket digital three-dimensional model is constructed, and the plane is directly used as the labial side of the digital three-dimensional model of the marking block. Since the thickness of the digital three-dimensional model of the marking block is consistent, the labial cheek side and the palatoglossal side of the digital three-dimensional model of the marking block are parallel.
In order to further realize the function of guiding the bracket to locate in the mesial-distal direction by the marking block, a guiding groove or a guiding raised strip is designed or arranged at the middle part of the cheek side surface and/or the part of the middle part close to the gingiva of the digital three-dimensional model of the marking block, and the mesial surface of the guiding groove or the guiding raised strip is matched with the mesial surface of the bracket central groove, and the mesial surface is matched with the mesial surface of the bracket central groove. For realizing the matching of the guide groove or the guide convex strip mesial surface of the digital three-dimensional model of the marking block and the mesial surface of the central groove of the bracket, a plane (called a groove mesial virtual plane) tangent to the mesial surface of the central groove of the corresponding tooth bracket is constructed, and the plane is directly used as the guide groove or the guide convex strip mesial surface of the marking block. For realizing the matching of the distal surface of the guide groove or the guide raised strip of the digital three-dimensional model of the marking block and the distal surface of the central groove of the bracket, a plane (called a groove distal virtual plane) tangent to the distal surface of the central groove of the corresponding tooth bracket is constructed, and the plane is directly used as the distal surface of the guide groove or the guide raised strip of the marking block. The width of the central groove in the bracket digital three-dimensional model ranges from 0.5 mm to 4mm, so that the width of the guide groove or the guide raised line on the digital three-dimensional model of the marking block is designed to be 0.5 mm to 4mm. In addition, for easy recognition, the depth of the guide groove is designed to be 0.5-1mm, and the height of the guide convex strip is designed to be 0.5-1mm. Furthermore, the guide groove/guide rib may extend through the middle of the marker block or may be located only in the middle of the marker block near the gingival part.
5) And (3) and (4) manufacturing a connecting block digital three-dimensional model between the plywood digital three-dimensional model and the marking block digital three-dimensional model. The number of the digital three-dimensional models of the connecting block is consistent with that of the digital three-dimensional models of the marking block, at least one of the two can be manufactured, and the number of the two can be 1 to 16 according to the orthodontic requirement of a patient. The face of each connecting block digital three-dimensional model facing the marking block is connected with the palatoglossal side face of the marking block digital three-dimensional model, and the face facing the plywood is connected with the plywood digital three-dimensional model. In order to ensure that the square end surface of the connecting block and the nonfunctional surface of the plywood are continued to be coplanar, the nonfunctional virtual plane of the digitized three-dimensional model of the plywood is used as the digitized three-dimensional model of the connecting block to be integrated Fang Duanmian. In order to avoid the digital three-dimensional model of the connecting block from shielding the lip cheek surfaces of the corresponding teeth, the gingival square end surface of the digital three-dimensional model of the connecting block needs to be not lower than the most convex position of the teeth facing the mating direction. Therefore, a plane parallel to the nonfunctional virtual plane of the ply-board digitized three-dimensional model is established as the connecting block digitized three-dimensional model compact Fang Duanmian through the bump of the corresponding tooth partner. In order to ensure that the near and far middle surfaces of the connecting block digital three-dimensional model are respectively continued with the near and far middle surfaces of the marking block digital three-dimensional model, the near and far middle surfaces of the connecting block digital three-dimensional model are required to be coplanar with the near and far middle surfaces of the marking block digital three-dimensional model, so that the near and middle surfaces of the marking block digital three-dimensional model are directly used as the near and middle surfaces of the connecting block digital three-dimensional model, and the far and middle surfaces of the marking block digital three-dimensional model are directly used as the far and middle surfaces of the connecting block digital three-dimensional model. The connecting block digital three-dimensional model is defined by the square end face, the gingival square end face, the mesial surface and the distal surface, and is connected with the marking block digital three-dimensional model to form a structure with a longitudinal section shape of L-shaped upper jaw or L-shaped lower jaw.
The distance between the digital three-dimensional model of the marking block and the digital three-dimensional model of the plywood is not necessarily consistent, so that the thickness of the digital three-dimensional model of the connecting block is designed to be 1-8mm.
The length of the digital three-dimensional model of the connecting block is designed to be 0.2-5 mm because the end face of the digital three-dimensional model of the connecting block and the end face of the gum are respectively determined by the non-functional face of the digital three-dimensional model of the connecting plate and the most salient point of the tooth, and the distances between the most salient points of the teeth of different teeth positions and the non-functional face of the connecting plate are different.
Because the near and far middle planes of the connecting block digital three-dimensional model are coplanar with the near and far middle planes of the marking block digital three-dimensional model respectively, the width design of the connecting block digital three-dimensional model is consistent with the width of the corresponding marking block digital three-dimensional model, and is particularly 1.5-7 mm.
(6) Combining the plywood digital three-dimensional model in the step (3), the marking block digital three-dimensional model in the step (4) and the connecting block digital three-dimensional model in the step (5) by using three-dimensional graphic processing software to form a positioning device digital three-dimensional model.
(7) And (3) obtaining the positioning device by a rapid forming method through the digital three-dimensional model of the positioning device in the step (6). Firstly, importing the digitized three-dimensional model of the positioning device into rapid prototyping printing file editing software, in the editing software, enabling the nonfunctional surface of the plywood in the digitized three-dimensional model of the positioning device to be close to the table surface of a printing platform of a printer, and then rapidly prototyping by using photosensitive resin to obtain the guiding lip side bracket bonding positioning device.

2. Because the marking block designed in the positioning device is a rectangular cube with a stable structure or an inverted trapezoid cube which turns over by 90 degrees, the supporting groove is only required to be abutted with one side of the marking block close to the gingival square for up-down positioning during positioning, and the side surface of the supporting groove is similar to a smooth plane, so that the manufacturing difficulty of the marking block is greatly reduced, deformation and displacement of the marking block caused by extrusion of the supporting groove are avoided in clinical operation, the bonding precision is better ensured, and meanwhile, the up-down positioning of the supporting groove is easier and more accurate.
3. Because the outer side surface of the marking block designed in the positioning device is also provided with the guide groove or the guide raised line, the center groove on the bracket can be aligned with the guide groove or the guide raised line and the parallel vertical planes on the two sides are flush with the two sides of the marking block to perform multidirectional positioning when the bracket is adhered, so that the accuracy of bracket adhesion can be greatly improved without depending on the experience of doctors.
4. Because the marking block designed in the positioning device provided by the invention only contacts the bracket when the bracket is closed, certain diseased teeth which are not provided with redundant gaps in the middle of the tooth surface of the bonding bracket due to the dislocation of the teeth can be indirectly bonded by the bracket by using the positioning device, so that the application range of indirectly bonding the mismatching deformed teeth is enlarged.
5. Because the positioning device provided by the invention is positioned by the marking blocks fixedly connected to the outer sides of the plywood, doctors can directly bond the bracket on the dentition of a patient at the corresponding position of the gum of the marking blocks in the positioning device, so that the operation is convenient, the influence of the near-middle marking blocks on the far-middle operation vision is obviously reduced, and the clinical operation efficiency is improved.
6. The plywood in the locating device provided by the invention only covers the incisor edge and the palatoglossal side surface of part or all of incisors, and/or the mesial-distal inclined edge and the palatoglossal side surface of part or all of cuspids, and/or the occlusal surface and the palatoglossal side surface of part or all of rear teeth, and does not cover the labial (buccal) surface of teeth, so that the locating device can be prevented from being stuck by bracket adhesives in the bracket bonding process, and the problem that the locating device is difficult to dislocate after the bracket bonding is avoided.
7. Because the marking blocks in the positioning device provided by the invention have no wrapping relation on the near-far middle adjacent surfaces of the bracket, brackets with different sizes can use the positioning device, and the application range of the positioning device is greatly enlarged.
8. The marking blocks in the positioning device are connected through the connecting blocks extending from the side surfaces of the lips (cheeks) of the main body of the plywood, and a supporting rod structure is not required to be added during manufacturing, namely, the supporting rod structure is not required to be independently added on the marking blocks as in the prior art (figure 1), so that the position of the supporting rod is not required to be manually and finely adjusted during manufacturing, the manufacturing process is greatly simplified, the supporting rods are not required to be removed one by one after molding, and the trouble is reduced.

Example 7
The positioning device for guiding the lip side bracket bonding provided in the above embodiment 1 is manufactured according to the following steps:
(1) Firstly, scanning all dentition of the mandible of a patient by using an intraoral scanner, and then, processing by using intraoral scanner software to obtain a mandible dentition digital three-dimensional model 9 of the patient in an occlusion position;
(2) Adopting three-dimensional graphic processing software, virtually arranging a bracket 7 digital three-dimensional model of all dentitions of the mandible on the dentition surface of the digital three-dimensional model 9 of all dentitions of the mandible obtained in the step (1) according to the requirements of doctors (see figure 19);
(3) Manufacturing a digital three-dimensional model of the plywood 1 (see figure 20) according to the matching formula of the digital three-dimensional model 9 of all the teeth of the matched mandible in the step (2), wherein the thickness of the digital three-dimensional model of the plywood 1 is 4mm, and the digital three-dimensional model is divided into a functional surface and a non-functional surface; the non-functional surface is a smooth horizontal surface and is flush with the plane of the marking block 3 close to the fitting direction, the functional surface is provided with an occlusion dental impression matched with the dental surface, the depth of the occlusion dental impression is 3mm at the 33 dental cusps, 2mm at the 37 dental distal middle buccal cusps, the positions of the other teeth in each anatomical part are between 2 and 3mm, the outer edge surfaces at two sides of the occlusion dental impression are matched with the labial cheek surfaces of the mandibular teeth, and the inner edge surfaces are matched with the palatogloss of the corresponding mandibular teeth. The plate 1 covers the incisor edge of the mandibular incisors (32 teeth, 41 teeth, 42 teeth) and part of the palatoglossal side, the mesial-distal mesial-oblique ridge of the cuspid (33 teeth, 43 teeth) and part of the palatoglossal side, and the occlusal surface of the posterior teeth (36-34 teeth, 44-46 teeth) and part of the palatoglossal side.
(4) In the step (2), the digital three-dimensional model of 13 marking blocks 3 is manufactured according to the formula of the digital three-dimensional model of the bracket 7 (see fig. 21), and the thickness of each marking block 3 is designed to be 1.5mm, so that the labial cheek side and the palatoglossal tongue side of the digital three-dimensional model of the marking block 3 are parallel.
In order to realize the function of guiding the bracket 7 to be bonded in place in the mesial-distal direction of the marking block 3, on one hand, the mesial surface of the digitized three-dimensional model of the marking block 3 is required to be matched with the mesial surface of the digitized three-dimensional model of the bracket 7, specifically, a plane tangential to the mesial bracket wing of the digitized three-dimensional model of each tooth bracket 7 (called a bracket wing mesial virtual plane) is constructed in the mesial center of the corresponding tooth bracket 7, and the plane is directly used as the mesial surface of the digitized three-dimensional model of the marking block 3; on the other hand, the distal surface of the digitized three-dimensional model of the marking block 3 is required to be matched with the distal surface of the digitized three-dimensional model of the bracket 7, specifically, a plane tangential to the distal surface of the distal bracket wing of the digitized three-dimensional model of each tooth bracket 7 (called a distal virtual plane of the bracket wing) is constructed, and the plane is directly used as the distal surface of the digitized three-dimensional model of the marking block 3. While the marking block 3 digitizes the three-dimensional model with the mesial and distal surfaces parallel. Depending on the specific differences in the width of the digitized three-dimensional model of the patient's different dental brackets 7, this embodiment designs the marker block 3 to have a width of 3mm at 32 teeth, 7mm at 37 teeth, and between 3-7mm at the remaining teeth.
In order to realize the contact of the marking block 3 and the bracket 7 to realize the vertical positioning and the connection with the plywood 1 through the connecting block 6, on one hand, the matching of the gingiva Fang Duanmian of the digital three-dimensional model of the marking block 3 and the square end surface of the digital three-dimensional model of the bracket 7 is required, specifically, a plane tangent to the square of the Fang Tuocao wings of the digital three-dimensional model of each tooth bracket 7 (called a virtual plane of the bracket wings) is constructed, and the plane is directly used as the gingival end surface of the digital three-dimensional model of the marking block 3. On the other hand, in order to realize that the combined end face of the digital three-dimensional model of the marking block 3 is flush with the nonfunctional plane of the plywood 1, a virtual plane (called as a virtual plane of the nonfunctional plane of the plywood) overlapped with the nonfunctional plane of the digital three-dimensional model of the plywood 1 is constructed, and the plane is directly used as a combination Fang Duanmian of the digital three-dimensional model of the marking block 3. Because the distances between the bracket wing square virtual planes of the digitized three-dimensional models of different dental brackets 7 and the nonfunctional virtual planes of the plywood 1 are different, the lengths of the digitized three-dimensional models of the marking blocks 3 are also different. In this embodiment the length of the marker block 3 is 2mm at 41 teeth, 4mm at 36 teeth and between 2-4mm at the remaining teeth. In addition, the bracket wing square virtual plane may or may not be parallel to the non-functional virtual plane of the board 1 due to the difference in the positions of the brackets 7.
To achieve the orientation of the digital three-dimensional model labial-lingual surface of the tag block 3 in the direction of the labial-lingual jaw of the bracket 7, it is necessary that the labial-buccal surface of the digital three-dimensional model of the tag block 3 be matched with the labial-buccal surface of the digital three-dimensional model of the bracket 7, specifically, a plane (called a virtual plane of the labial-buccal surface of the bracket) tangential to the labial-buccal surface of the bracket wing of the digital three-dimensional model of each tooth bracket 7 is constructed, and the plane is directly used as the labial-buccal surface of the digital three-dimensional model of the tag block 3.
Because the proximal and distal surfaces of the digital three-dimensional model of the marking block 3 are parallel, the square virtual plane of the bracket wing and the nonfunctional virtual plane of the plywood 1 may be parallel or not, the cheek side and palatoglossal side of the digital three-dimensional model of the marking block 3 are parallel, and the digital three-dimensional model of the marking block 3 is finally designed to be rectangular or inverted trapezoid with 90 degrees of overturn.
In addition, in order to further realize the function of guiding the bracket 7 to locate in the mesial and distal directions by the marking blocks 3, a guiding groove 4 is designed at the middle part or the part close to the gum square part of the cheek side surface of each marking block 3 digital three-dimensional model, on one hand, the mesial surface of the guiding groove 4 of the marking block digital three-dimensional model is matched with the mesial surface of the bracket central groove 8, a tangential plane (called a groove mesial virtual plane) is constructed at the mesial surface of the corresponding tooth bracket central groove 8, and the plane is directly used as the mesial surface of the guiding groove 4 of the marking block. On the other hand, the distal surface of the digital three-dimensional model guiding groove 4 of the marking block is matched with the distal surface of the central groove 8 of the bracket, a plane (called a groove distal virtual plane) tangential to the distal surface of the central groove 8 of the corresponding tooth bracket is constructed, and the plane is directly used as the distal surface of the guiding groove 4 of the marking block. In this embodiment, since the widths of the bracket central grooves 8 used are all 0.5mm, the width of the digital three-dimensional model guide groove 4 of the marking block 3 is designed to be 0.5mm. For easy recognition, the depth of the guide groove 4 is designed to be 0.5mm, and the guide groove in the middle of the labial cheek side of the corresponding mark block with 41 teeth is designed to be penetrated, while the guide groove 4 in the labial cheek side of the corresponding mark block 3 with the rest teeth is designed to be opened in the middle near gingival square part, and is not penetrated.
(5) And (3) and (4) manufacturing 13 digital three-dimensional models of the connecting blocks 6 between the digital three-dimensional model of the plywood 1 and the digital three-dimensional model of the marking block 3 (see figure 20). The face of each connecting block 6 facing the marking block 3 on the digital three-dimensional model is connected with the palatoglossal side of the digital three-dimensional model of the marking block 3, and the face facing the plywood 1 is connected with the digital three-dimensional model of the plywood 1.
In order to ensure that the square end surface of the connecting block 6 and the nonfunctional surface of the plywood 1 continue to be coplanar, the nonfunctional virtual plane of the digitized three-dimensional model of the plywood 1 is used as the digitized three-dimensional model of the connecting block 6 to be integrated Fang Duanmian. In order to avoid the digital three-dimensional model of the connecting block from shielding the lip cheek surface of the corresponding tooth, the gingival side end surface of the connecting block 6 is required to be not lower than the most convex position of the tooth towards the mating side, specifically, a plane parallel to the nonfunctional virtual plane of the digital three-dimensional model of the plywood 1 is established through the most convex point of the mating side of the corresponding tooth and is used as the gingival side end surface of the digital three-dimensional model of the connecting block 6. In addition, in order to ensure that the connection block 6 continues with the proximal and distal surfaces of the marker block 3, it is necessary to make the proximal and distal surfaces of the digital three-dimensional model of the connection block 6 coplanar with the proximal and distal surfaces of the digital three-dimensional model of the marker block 3, respectively, so that the proximal surface of the digital three-dimensional model of the marker block 3 is directly used as the proximal surface of the digital three-dimensional model of the connection block 6, and the distal surface of the digital three-dimensional model of the marker block 3 is directly used as the distal surface of the digital three-dimensional model of the connection block 6.
The middle surface and the far surface of the digital three-dimensional model of the connecting block 6 are coplanar with the middle surface and the far surface of the digital three-dimensional model of the marking block 3 and are connected with the digital three-dimensional model of the marking block 3, so that a structure with a L-shaped longitudinal section is formed together. Because the distance between the digitized three-dimensional model of the marking block 3 and the digitized three-dimensional model of the plywood 1 is inconsistent, the thickness of each connecting block 6 is different, the specific thickness is 1mm at the 41 teeth, 3mm at the 46 teeth and 1-3mm at the rest teeth. In addition, since the end face of the digital three-dimensional model of the connecting block 6 and the end face of the gum square are respectively determined by the nonfunctional face of the digital three-dimensional model of the plywood 1 and the most protruding point of the tooth, the most protruding points of the teeth of different teeth positions are different, and therefore, the lengths of the connecting blocks 6 are also different. In this embodiment, the length 41 teeth of the digital three-dimensional model of the connecting block 6 is 1mm, the 46 teeth are 3mm, and the rest teeth are 1-3 mm. In addition, because the near and far middle planes of the digital three-dimensional model of the connecting block 6 are respectively coplanar with the near and far middle planes of the digital three-dimensional model of the marking block 3, the width of each digital three-dimensional model of the connecting block 6 is respectively consistent with the width of the corresponding digital three-dimensional model of the marking block 3, namely, the width 32 teeth of the digital three-dimensional model of the connecting block 6 is 3mm, the 37 teeth are 7mm, and the rest teeth are 3-7 mm.
(6) Combining the three-dimensional model digitized by the plywood 1 in the step (3), the three-dimensional model digitized by the marking block 3 in the step (4) and the three-dimensional model digitized by the connecting block 6 in the step (5) by using three-dimensional graphic processing software to form a positioning device digitized three-dimensional model (see figure 22).
(7) And (3) importing the digitized three-dimensional model of the positioning device into rapid prototyping printing file editing software, in the editing software, enabling the nonfunctional surface of the plywood 1 in the digitized three-dimensional model of the positioning device to be close to the table top of a printing platform of a printer, and then rapidly prototyping by using photosensitive resin to obtain the guiding lip side bracket bonding positioning device.
