DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0018] Different people have different tooth structures. When dentists bond veneers to patients, they can use guides to position the veneers. The veneers of teeth usually have a certain arc coverage on the left and right sides. This coverage can play a left and right positioning function for the veneers during the actual bonding process. Therefore, the left and right positions of the veneers are relatively unique, such as Figure 1As shown. The veneer positioning problem is mainly the positioning problem of the veneer 200 at the incisal end. Because human gums are soft, and under different conditions, such as periodontitis, bad brushing habits, etc., the gums will swell or recede, making the gums higher or lower, which will affect the doctor's judgment when pasting the dental veneer 200. In the current related technology, the positioning structure of the guide plate is relatively complex in the positioning problem of the veneer at the incisal end, which also makes the design of the guide plate relatively complex.

[0019] The guide plate of the embodiment of the present application includes a molar positioning occlusal surface and other tooth incisal end limiting grooves; the molar positioning occlusal surface is complementary to the occlusal surface of the patient's posterior molars, and is used to fix the guide plate, stabilize the relative position of the other tooth incisal end limiting grooves and the incisal ends of the patient's other teeth, thereby stabilizing the relative position of the veneer and the patient's other teeth; the other tooth incisal end limiting grooves limit the incisal ends of the patient's other teeth and the incisal ends of the veneer, and limit the installation position of the veneer relative to the patient's other teeth, including a tooth complementary position complementary to the incisal ends of the patient's other teeth and a veneer complementary position complementary to the incisal ends of the corresponding veneer. The molar positioning occlusal surface is complementary to the occlusal surface of the patient's posterior molars, which utilizes the complementary structure of the occlusal surfaces of the patient's upper and lower posterior molars to naturally restrict and position the teeth in the direction of the occlusal surface. The tooth complementary positions of the other tooth incisal end limiting grooves are complementary to the incisal ends of the patient's other teeth, and the veneer complementary positions are complementary to the incisal ends of the corresponding veneers. This is also a feature of utilizing the complementary structure of the patient's upper and lower teeth at the incisal ends to naturally restrict and position the teeth on the incisal ends. The molar positioning occlusal surface and the other tooth incisal end limiting grooves have a simple structure, which utilizes the natural laws of the patient's teeth themselves, which simplifies the guide plate manufacturing process.

[0020] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] See also Figures 2 to 4 , Figure 2 This is a structural schematic diagram of an embodiment of a guide plate for tooth veneer bonding in the present application from one perspective, Figure 3 yes Figure 2 A schematic diagram of the structure from another perspective. Figure 4 yes Figure 2 The guide plate 100 comprises: a molar positioning occlusal surface 1 and other tooth incisal limiting grooves 2.

[0022] The molar positioning occlusal surface 1 is complementary to the occlusal surface of the patient's posterior molars, and is used to fix the guide plate 100, stabilize the relative position of the other teeth's incisal end limiting groove 2 and the incisal ends of the patient's other teeth, and thus stabilize the relative position of the veneer and the patient's other teeth. The other teeth's incisal end limiting groove 2 is used to limit the incisal ends of the patient's other teeth and the incisal ends of the veneer, and to limit the installation position of the veneer relative to the patient's other teeth, including a tooth complementary position 21 complementary to the incisal ends of the patient's other teeth and a veneer complementary position 22 complementary to the incisal ends of the corresponding veneer.

[0023] The molar positioning occlusal surface 1 is complementary to the occlusal surface of the patient's posterior molars, so that the molar positioning occlusal surface 1 can naturally fix the guide plate 100 by utilizing the complementary positioning characteristics of the patient's upper and lower molars, and the other teeth incisal end limiting grooves 2 include tooth complementary positions 21 and veneer complementary positions 22, the tooth complementary positions 21 are complementary to the incisal ends of the patient's other teeth, and the veneer complementary positions 22 are complementary to the incisal ends of the corresponding veneers, so that the other teeth incisal end limiting grooves 2 can also utilize the complementary positioning characteristics of the patient's upper and lower teeth to naturally limit the incisal ends of the patient's other teeth and the incisal ends of the veneers, and at the same time limit the installation position of the veneers relative to the patient's other teeth. Therefore, when the molar positioning occlusal surface 1 fixes the guide plate 100, the relative position of the other teeth incisal end limiting grooves 2 and the incisal ends of the patient's other teeth can be stabilized, thereby stabilizing the relative position of the veneer and the patient's other teeth.

[0024] In the embodiment of the present application, the molar positioning occlusal surface 1 is complementary to the occlusal surface of the patient's posterior molars. This is a feature that the occlusal surfaces of the patient's upper and lower posterior molars have a complementary structure, thereby naturally restricting the position of the teeth in the direction of the occlusal surface. The tooth complementary position 21 of the other tooth incisal end limiting groove 2 is complementary to the incisal ends of the patient's other teeth, and the veneer complementary position 22 is complementary to the incisal ends of the corresponding veneers. This is also a feature that the patient's upper and lower teeth have a complementary structure at the incisal ends, thereby naturally restricting the position of the teeth on the incisal ends. Compared with the specially designed positioning structure in the related art, although it can also position the veneer on the incisal end, its structure is complex. The structure of the molar positioning occlusal surface 1 and the other tooth incisal end limiting groove 2 in the embodiment of the present application utilizes the natural laws of the patient's teeth themselves, and its structure is simple, which simplifies the guide plate manufacturing process.

[0025] In some embodiments, the side wall 211 of the tooth complementary position 21 of the other tooth cutting end limiting groove 2 close to the lingual side is complementary to the lingual side of the corresponding tooth.

[0026] In the embodiment of the present application, the side wall 211 of the tooth complementary position 21 close to the lingual side is complementary to the lingual side of the corresponding tooth, so that the side wall 211 of the tooth complementary position 21 close to the lingual side can better fit together with the lingual side of the corresponding tooth, so that the tooth complementary position 21 can more accurately define and position the corresponding tooth.

[0027] In some embodiments, the side wall 221 of the veneer complementary position 22 of the other tooth cutting end limiting groove 2 close to the labial side is complementary to the outer side of the corresponding tooth veneer.

[0028] In the embodiment of the present application, the side wall 221 of the veneer complementary position 22 close to the labial side is complementary to the outer side of the corresponding tooth veneer, so that the side wall 221 of the veneer complementary position 22 close to the labial side can be better fitted with the outer side of the corresponding tooth veneer, so that the veneer complementary position 22 can more accurately limit and position the corresponding tooth veneer.

[0029] In some embodiments, the height of the side wall 211 of the tooth complementary site 21 close to the tongue side is greater than the height of the side wall 221 of the veneer complementary site 22 close to the labial side.

[0030] In the embodiment of the present application, the height of the side wall 211 of the tooth complementary position 21 close to the tongue side is greater than the height of the side wall 221 of the veneer complementary position 22 close to the labial side. On the one hand, it is convenient for the doctor to perform related operations on the veneer, and on the other hand, it is convenient for the doctor to observe the adhesion of the veneer to the teeth. On the other hand, compared with the related technology in which the height of the side wall of the guide plate close to the tongue side is the same as the height of the side wall of the guide plate close to the labial side and the purpose of veneer-related operations and observation is achieved by opening a window on the side wall of the guide plate close to the labial side, the embodiment of the present application is simpler, more convenient, and saves materials by reducing the height of the side wall of the veneer complementary position close to the labial side.

[0031] In some embodiments, an overflow hole 222 for adhesive discharge is formed on the side wall 221 of the veneer complementary position 22 close to the lip side.

[0032] After the veneer is attached to the tooth, it needs to be cured by light, which will discharge the excess glue between the veneer and the tooth. The side wall 221 of the veneer complementary position 22 close to the labial side is provided with an overflow hole 222 to discharge the excess glue.

[0033] According to actual needs, the side wall 221 of the veneer complementary position 22 close to the lip side can be provided with one overflow hole 222, two overflow holes 222, or more overflow holes 222.

[0034] In some embodiments, an overflow groove 223 for debonding is provided at the bottom of the veneer complementary position 22 , one end of the overflow groove 223 is connected to the overflow hole 222 , and the other end of the overflow groove 223 extends to the connecting line 3 between the tooth complementary position 21 and the veneer complementary position 22 .

[0035] In the embodiment of the present application, an overflow groove 223 is provided at the bottom of the veneer complementary position 22, and one end of the overflow groove 223 extends to the connecting line 3 between the tooth complementary position 21 and the veneer complementary position 22, so that the excess glue between the tooth and the veneer can be discharged into the overflow groove 223 more conveniently and quickly. The other end of the overflow groove 223 is connected to the overflow hole 222, and the excess glue is quickly discharged to the overflow hole 222 of the side wall 221 of the veneer complementary position 22 close to the lip side through the overflow groove 223.

[0036] In some embodiments, the overflow hole 222 is hexagonal in shape, so that the excess glue can be discharged more quickly.

[0037] In some embodiments, the guide plate 100 includes a plurality of adjacently arranged other tooth cutting end limiting grooves 2, and the height of the limiting platform 4 where the plurality of other tooth cutting end limiting grooves 2 are located is complementary to the height of the corresponding teeth.

[0038] In the embodiment of the present application, the heights of the limiting platforms 4 where the plurality of other teeth's cutting end limiting grooves 2 are located may be inconsistent. Since the heights of each of the patient's teeth may be different, some teeth are high and some are low. In order to match the height differences of the teeth, the heights of the limiting platforms 4 where the plurality of other teeth's cutting end limiting grooves 2 are located are complementary to the heights of the corresponding teeth, that is, the heights of the limiting platforms 4 corresponding to the high teeth can be lower, and the heights of the limiting platforms 4 corresponding to the low teeth can be higher. Generally speaking, the heights of the front teeth of a patient are high, and the heights of the teeth on both sides of the patient are low. Therefore, the heights of the limiting platforms 4 corresponding to the front teeth of a patient are usually low, and the heights of the limiting platforms 4 corresponding to the teeth on both sides of the patient are high. The specific heights can be determined according to the actual conditions of each patient's teeth.

[0039] In some embodiments, the guide plate 100 is made of a biocompatible material, so that the guide plate can be compatible with human tissues and avoid causing allergic reactions and toxic reactions.

[0040] In some embodiments, the guide plate 100 is integrally printed by a light-curing 3D printing device. In this way, a personalized guide plate can be customized according to the needs of each patient and the actual situation of the teeth, which can simplify the operation of professionals such as doctors and nurses.

[0041] In some embodiments, the guide plate 100 further includes: a positioning platform 5 and a limiting platform 4 , the molar positioning occlusal surface 1 is located on the positioning platform 5 , and the other tooth incisal end limiting grooves 2 are arranged on the limiting platform 4 .

[0042] See also Figure 5 , Figure 5 The present invention is a flow chart of an embodiment of a method for manufacturing a guide plate for bonding a tooth veneer, wherein the manufacturing method comprises:

[0043] Step S101: providing a three-dimensional dental model obtained by scanning the patient's mouth.

[0044] Step S102: According to the posterior molar model and other tooth models of the three-dimensional dental model, the molar positioning occlusal surface and other tooth incisal end limiting grooves of the guide plate are designed respectively, wherein the molar positioning occlusal surface is complementary to the occlusal surface of the patient's posterior molars, and is used to fix the guide plate, stabilize the relative position of the other tooth incisal end limiting grooves and the incisal ends of the patient's other teeth, thereby stabilizing the relative position of the veneer and the patient's other teeth, and the other tooth incisal end limiting grooves are used to limit the incisal ends of the patient's other teeth and the incisal ends of the veneer, and limit the installation position of the veneer relative to the patient's other teeth, including a tooth complementary position complementary to the incisal ends of the patient's other teeth and a veneer complementary position complementary to the incisal ends of the corresponding veneer.

[0045] Step S103: obtaining a designed guide plate model according to the designed molar positioning occlusal surface of the guide plate and other tooth incisal limit grooves.

[0046] Step S104: manufacturing the guide plate according to the designed guide plate model to obtain the guide plate.

[0047] The method for making the guide plate in the embodiment of the present application designs the molar positioning occlusal surface and other tooth incisal end limiting grooves of the guide plate according to the three-dimensional model of the dental mold obtained by scanning the patient's mouth, so that the molar positioning occlusal surface is complementary to the occlusal surface of the patient's posterior molars, the tooth complementary positions of the other tooth incisal end limiting grooves are complementary to the incisal ends of the patient's other teeth, and the veneer complementary positions are complementary to the incisal ends of the corresponding veneers, so that the designed guide plate model can be obtained, and the guide plate can be made according to the guide plate model. The production method is simple and convenient.

[0048] In some embodiments, step S104, manufacturing the guide plate model according to the design to obtain the guide plate, may include: manufacturing the guide plate model according to the design, and printing the guide plate by using a light-curing 3D printing method.

[0049] See also Figure 6 , Figure 6It is a flow chart of an embodiment of a method for using a guide plate for tooth veneer bonding of the present application. The method is applicable to any of the guide plates described above, and the method includes: steps S201 to S203.

[0050] Step S201: After pasting the veneers on the patient's teeth, put on the guide plate so that the molar positioning occlusal surface of the guide plate fixes the guide plate, stabilizes the relative position of the other tooth incisal end limiting grooves of the guide plate and the incisal ends of the patient's other teeth, thereby stabilizing the relative position of the veneer and the patient's other teeth, so that the tooth complementary positions complementary to the incisal ends of the patient's other teeth in the incisal end limiting grooves of the other teeth define the incisal ends of the patient's other teeth, and the veneer complementary positions complementary to the incisal ends of the corresponding veneers in the incisal end limiting grooves of the other teeth define the incisal ends of the veneers, and the installation position of the veneer relative to the patient's other teeth is limited.

[0051] Step S202: After the veneer is light-cured, the guide plate is removed, and the veneer is further light-cured.

[0052] Step S203: cleaning the glue overflowed after light curing.

[0053] The specific use process of the guide plate can be as follows: the doctor performs veneer bonding on a single tooth, and first separates the teeth on both sides with special tape. After applying glue to the veneer, initially stick it on the tooth to be bonded. Gently press and shake left and right to align the left and right positions; then move the veneer as far as possible toward the gum side. Then put the guide plate on the occlusal surface, use the molars to position it, and keep the guide plate and the tooth from shaking. Figure 7 As shown, Figure 7 This is a schematic diagram of putting the guide plate on the occlusal surface of the patient's teeth after the veneers are pasted on the patient's teeth. Press the guide plate with one finger and push the veneer toward the occlusal surface with the other finger until the veneer is close to the guide plate and cannot move. At this time, the upper and lower positioning of the veneer is completed. Use ultraviolet light to cure the veneer near the gum position; remove the guide plate, and then continue to cure the veneer near the occlusal position. After that, clean up the overflowed glue, and the bonding of this veneer is completed. You can continue to change to the next tooth for veneer pasting, and the guide plate can continue to be used.
