Description

Technical Field

[0001] The utility model relates to the technical field of polymerization degree checkers, in particular to a polymerization degree checker for tooth preparation for oral cavity. Background Art

[0002] Oral fixed prosthesis treatment often requires the production of various artificial full crown restorations, which are worn on the natural teeth that have been prepared by grinding. After tooth preparation, the abutment teeth are required to meet the requirements of retention and resistance. In order to obtain a stronger retention force and eliminate the undercut of the abutment tooth axial surface, it is more appropriate to control the degree of convergence of the relative axial surfaces of the prepared tooth between 2-6°. If the degree of convergence of the axial surface is too small, it is difficult to eliminate the undercut of the natural tooth, and the denture is difficult to wear and put in place; if the degree of convergence of the axial surface is too large, the denture is poorly retained and easy to loosen and fall off. Therefore, when preparing teeth in clinical practice, it is necessary to check the teeth using an oral restoration tooth preparation axial surface convergence checker.

[0003] There are many types of such axial plane convergence checkers on the market today, which can basically meet people's needs. However, there are still certain problems. The existing axial plane convergence checkers are not flexible enough in checking the convergence degree, and the convergence degree is not enough to appear undercut.
