Abstract

The invention discloses a digitized metal gingival wall lifting guide plate and a manufacturing method thereof. The technical problems of low operation efficiency and inaccurate assistance of an auxiliary tool in an existing gingival wall lifting surgery are solved. The manufacturing method comprises the following steps that 1, dentition data are obtained through dental scanning equipment, and jawbone data are obtained through dental CBCT equipment; 2, the dentition data and jawbone data are fitted to obtain defective subgingival data, and an anatomical shape of a tooth root is obtained, so that complete data of a defective tooth are obtained; 3, a virtual wax pattern is designed according to the complete data of the defective tooth; 4, on the basis of the virtual wax pattern, a retentionstructure is designed at the defect tooth; 5, a lifting plate is designed at the lower edge of the defective gingiva according to the virtual wax pattern and the anatomical shape of the tooth root; 6,the retention structure is connected with the lifting plate to form the gingival wall lifting guide plate; and 7, 3D printing is carried out on the gingival wall lifting guide plate according to gingival wall lifting guide plate information. The manufacturing method has the advantages of high operation efficiency, good repair effect and the like.

Description

technical field

[0001] The invention relates to the technical field of gingival wall lifting surgery auxiliary tools, in particular to a digital metal gingival wall lifting guide plate and a manufacturing method thereof. Background technique

[0002] When performing indirect restoration of large-area tooth defects, subgingival margins are sometimes encountered, which will increase the difficulty of moisture isolation in the operation area, and are not conducive to the preparation of impressions and the finishing line of the cervical margin with polish.

[0003] Clinically, two methods are usually adopted to solve such problems: one is to expose the subgingival edge through crown lengthening, and the other is to lift the subgingival edge to the supragingival through gingival wall lifting.

[0004] To a certain extent, gingival wall lifting can be considered as a minimally invasive alternative to crown lengthening, which can effectively avoid attachment loss and restore the c...
