[0024] Please refer to Figure 1 The veneer tooth preparation guide shown in an embodiment of the application comprises a pair of positioning tooth caps 10 and a tooth preparation assembly arranged between the pair of positioning tooth caps 10, the pair of positioning tooth caps 10 is used to connect with the teeth to fix the tooth preparation assembly at the veneer tooth, so as to facilitate the tooth preparation assembly to cooperate with the tooth grinding equipment to grind the veneer tooth. It should be noted that the veneer tooth is the tooth that needs to be veneered.

[0025] A pair of positioning mouthguards 10 are symmetrically arranged on the teeth on both sides of the veneered teeth, and the positioning mouthguards 10 are in a cladding shape and are arranged on the teeth on both sides of the veneered teeth from top to bottom. The fixing effect of the tooth preparation assembly is improved by the two-side fixing mode, so as to avoid loosening of the tooth preparation assembly during the grinding process.

[0026] The tooth preparation assembly comprises a grinding guide plate 30 and a connecting piece 20 connected between the grinding guide plate 30 and the positioning mouthguard 10. The grinding guide plate 30 is formed with a guide groove 31 for guiding the grinding device. The connecting piece 20 is formed with an operation window 21 on the top and the front side of the veneered teeth respectively. The grinding guide plate 30 is fixedly arranged at one of the operation windows 21, and the other operation window 21 is used for observing the veneered teeth.

[0027] In an embodiment, the grinding guide plate 30 is arranged at the operation window 21 on the top of the veneered teeth, and the projection of the guide groove 31 in the vertical direction coincides with the front side of the veneered teeth. By arranging the grinding guide plate 30 on the top of the veneered teeth and arranging the guide groove 31 close to the front side of the veneered teeth, the grinding rod of the grinding device is inserted into the front of the veneered teeth from top to bottom, so as to facilitate the dentist to grind the front side of the veneered teeth. In addition, the operation window 21 on the front side of the connecting piece 20 is empty, so that the dentist can directly observe the grinding condition of the front side of the veneered teeth through the empty operation window 21.

[0028] In an embodiment, the guide groove 31 is a circular arc waist hole. Since the front side of the teeth generally has a certain arc, the circular arc waist hole is arranged to form a guide track that matches the arc of the front side of the veneered teeth, so as to facilitate the control of the grinding device to grind.

[0029] Please refer to Figure 2 In another embodiment, the grinding guide plate 30 is arranged at the operation window 21 on the front side of the veneered teeth, and the projection of the guide groove 31 in the horizontal direction coincides with the top of the veneered teeth. By arranging the grinding guide plate 30 on the front side of the veneered teeth and arranging the guide groove 31 close to the top of the veneered teeth, the grinding rod of the grinding device is inserted into the top of the veneered teeth from the horizontal direction, so as to facilitate the dentist to grind the top of the veneered teeth. In addition, the operation window 21 on the top of the connecting piece 20 is empty, so that the dentist can directly observe the grinding condition of the top of the veneered teeth through the empty operation window 21.

[0030] In an embodiment, the guide groove 31 is a straight line waist hole. Since the top of the teeth generally has a certain plane, the straight line waist hole is arranged to form a guide track that matches the plane of the top of the veneered teeth, so as to facilitate the control of the grinding device to grind.

[0031] In an embodiment, the positioning mouthpiece 10 is made by 3D printing technology, which is scanned by a three-dimensional scanner first, and then printed by a 3D device according to the scanning data of the three-dimensional scanner to form the positioning mouthpiece 10, which is a prior art and will not be described here.

[0032] At least one sleeve slot matched with the shape of the teeth on both sides of the veneered teeth is formed in the positioning mouthpiece 10. In the embodiment, six sleeve slots matched with the shape of the teeth are formed in one positioning mouthpiece 10, and four sleeve slots matched with the shape of the teeth are formed in the other positioning mouthpiece 10. The number of sleeve slots in the positioning mouthpiece 10 can be adjusted according to the position of the veneered teeth, as long as it can be fixed firmly to the tooth preparation assembly, which will not be limited here.

[0033] In an embodiment, a notch 11 communicating with the sleeve slot is formed on the upper surface of the positioning mouthpiece 10. The notch 11 is provided to facilitate the observation of whether the positioning mouthpiece 10 is sleeved in place, so as to determine whether the position of the molar guide plate 30 is correct, so as to facilitate the quick connection and matching of the veneering tooth preparation guide plate with the teeth, and to speed up the veneering tooth preparation process.

[0034] The present application connects and fixes the molar guide plate between a pair of positioning mouthpieces through the connecting piece to cooperate with the dentist to quickly perform the molar processing in the veneering tooth preparation process. The positioning mouthpiece is sleeved on the teeth on both sides of the veneered teeth, so as to fix the molar guide plate on the top or front side of the veneered teeth. Then the molar guide plate is used to guide the molar equipment, which effectively reduces the technical requirements of molar processing, thereby avoiding the harm to the patient caused by the molar operation failure. At the same time, the molar processing of the veneered teeth can be observed in real time through the operation window formed on the connecting piece, so as to facilitate the dentist to quickly perform the molar processing and improve the molar efficiency.

[0035] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.

[0036] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
