Problems solved by technology

[0002] At present, the bur limiter in the existing tooth preparation guide has too high requirements on the opening and vertical operation space, which limits the use of the dental preparation guide and brings trouble to the dentist; at the same time, the tooth preparation guide needs to be specially made Special burs not only increase the cost, but also have problems in production. Therefore, the application of the existing tooth preparation guide plate is not convenient enough, which is not conducive to popularization and application

Embodiment Construction

[0017] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] A method for designing and manufacturing a tooth preparation guide plate without a bur stopper of the present invention has the following steps:

[0019] (1) Scan the teeth and adjacent teeth that need to be prepared, and save the scanned data in STL format for future use;

[0020] (2) Design the three-dimensional shape of the tooth preparation with three-dimensional reverse engineering software;

[0021] (3) According to the shape of the tooth preparation described in step (2), design a guide groove on the guide plate that can guide the movement path of the dental bur throughout the entire process, and the axis of the guide groove is in contact with the gingival margin line or the intended grinding area of ​​the tooth preparation The outer edge line is parallel, and the cross-sectional width of the guide groove is the same as ...

Abstract

The invention relates to a method for designing and manufacturing a guide plate for tooth preparation without a bur limiter. (3) According to the shape of the tooth preparation in step (2), design a guide groove on the guide plate that can guide the movement path of the dental bur in the whole process; (4) Design a retaining ring on the adjacent teeth to serve as a retaining ring for the guide plate. (5) The guide groove and the retaining ring are integrated into the overall data of the guide plate, which is processed into a solid body with a 3D printer; (6) After the guide plate is completely seated on the dentition model, the operator holds the dental high-speed handpiece It moves along the guide groove of the guide plate, and the lower surface of the high-speed mobile phone is in close contact with the upper surface of the guide groove when moving. The invention can greatly reduce the high requirements of the bur stopper on the opening degree and the vertical operation space in the existing tooth preparation guide plate, and at the same time, no special bur is required, which is favorable for popularization and application.

Description

technical field [0001] The invention relates to a tooth preparation guide plate, in particular to a method for designing and manufacturing a tooth preparation guide plate without a bur stopper. Background technique [0002] At present, the bur limiter in the existing tooth preparation guide has too high requirements on the opening and vertical operation space, which limits the use of the dental preparation guide and brings trouble to the dentist; at the same time, the tooth preparation guide needs to be specially made The special-purpose bur not only increases the cost, but also has problems in production. Therefore, the application of the existing tooth preparation guide plate is not convenient enough, which is not conducive to popularization and application. Contents of the invention [0003] In order to overcome the above deficiencies, the present invention provides a method for designing and manufacturing a tooth preparation guide without a bur stopper, which can great...
