Abstract
Description
technical field
[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an axial-surface polymerization degree checker of an oral restorative tooth preparation. Background technique
[0002] Oral fixed restorative treatment often requires the production of various sleeve-like dentures, which are worn on the natural teeth prepared in the shape of a conical frustum. It is required that the degree of polymerization of the opposite axial surfaces of the frustum-shaped tooth preparation be controlled at six to eight degrees. In between, if the polymerization of the axial surface is too small, the denture is difficult to put in and put in place; if the polymerization of the axial surface is too large, the denture will be poorly retained and easy to loosen and fall off. Check the degree of polymerization of the axial surface of the oral restorative tooth preparation Usually, oral mirrors are used to check and wipe. Existing oral mirror...
