Embodiment 1

[0017] The guiding tooth preparation device is as follows: an angle indicating device is installed on the top of the mobile phone in a semi-embracing card-type manner. The angle indicating device is composed of a dial and a pointer. The dial can be circular, and there are scales indicating the angle on the upper and lower sides. The maximum includes plus or minus 20°. The angle of plus or minus 2° to 5° is marked in blue, and the line of plus or minus 10° is marked in red. The pointer It is connected with the dial by a shaft and a shaft sleeve (made of polytetrafluoroethylene).

[0018] Tooth preparation for the inlay repair of the patient's mandibular posterior tooth and surface defect: Prepare the cavity according to the requirements for the tooth preparation of the inlay restoration. On each side of the shaft wall, to observe the angle indicated by the scale of the guide plate, all the shaft walls should be parallel to each other or outward by 2°-5° (as shown in Figure 3)....

Embodiment 2

[0021] The guide tooth preparation device is: an angle indicating device (as shown in Figure 3) is installed on the top of the mobile phone and the two are all surrounded by a screw fastening type. The structure of the angle indicating device is the same as that of Embodiment 1 except that the joint between the pointer and the dial is a shaft made of polypropylene. The dial of the angle indicating device on the top of the mobile phone is circular; the dials of the two angle indicating devices are semicircular.

[0022] Tooth preparation for casting full crowns on the patient’s maxillary posterior teeth: follow the tooth preparation steps for casting full crowns, pay attention to guiding the use of tooth preparation devices when preparing the buccolingual and proximal surfaces, during the tooth preparation process, according to It is necessary to stop the preparation, and stick the mobile phone bur to all sides of the shaft wall to observe the angle indicated by the scale of th...

Embodiment 3

[0025] The tooth body preparation device for guiding is: an angle indicating device (as shown in accompanying drawing 2) is installed on the top and both sides of the mobile phone in a screw-fastened manner. The structure of the angle indicating device is the same as embodiment 1 except that the junction of the pointer and the dial is a shaft made of polyvinyl chloride. The dials of the angle indicators on the top and sides of the phone are circular.

[0026] Dental preparation steps for the restoration of the patient's maxillary anterior teeth with porcelain crowns:

[0027] Proceed according to the tooth preparation steps for the restoration of the maxillary anterior teeth with porcelain full crowns. During the preparation of the adjacent teeth, stop the preparation as needed, and stick the mobile phone bur to all sides of the adjacent axial wall to observe the scale indication of the guide plate Angle, so that the axial walls of the two adjacent faces are parallel to each ...

Abstract

The tooth preparation guiding device includes one dental hand piece and one angle indicator assembled on the dental hand piece. The angle indicator consists of one dial with angle scale, and one pointer connected to the dial in shaft-shaft box mode for rotating freely and gravitationally. When the tooth preparation guiding device is used in preparing tooth, the pointer indicated angle is adopted to guide the tooth repairing treatment accurately.

Description

technical field [0001] The present invention relates to dental tools, especially dental drills used in restoration treatments such as inlays, full crowns, and preparation of teeth in 3 / 4 crowns. Background technique [0002] At present, in the process of oral restorative treatment, such as: in full crown restoration, there are certain requirements for the axial wall of the tooth preparation. The axial walls are parallel to each other, which can increase the binding force and friction of the restoration, and is beneficial to the retention of the restoration. , but clinically, in order to facilitate the seating of the crown, the axial walls are required to converge slightly radially. Studies have shown that the retention force is inversely proportional to the degree of polymerization between the axial walls of the preparation, but the degree of polymerization between the axial walls is between 2° and 5°, which has relatively little effect on the retention force; if the degree ...
