Dental restoration tooth preparation axial surface polymerization degree inspector

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a dental restoration tooth preparation axial surface polymerization degree inspector which comprises a connecting rod, a mouth mirror is rotatably connected to the top end of the connecting rod through a rotating shaft, an anti-atomization mechanism is arranged in the mouth mirror, and an angle adjustingmechanism is arranged at the joint of the connecting rod and the mouth mirror. A battery storage cavity is formed in the mouth mirror, the battery storage cavity is located at the bottom end of the anti-atomization mechanism, the bottom end of the mouth mirror is rotationally connected with a storage cavity cover, the storage cavity cover is of a T-shaped structure, the anti-atomization mechanismis installed in the mouth mirror, when the mouth mirror is used, fog is prevented from being generated on the surface to affect observation in the oral cavity. The angle adjusting mechanism is installed between the connecting rod and the stomatoscope to facilitate angle adjustment of the stomatoscope, and the heat preservation layer and the waterproof layer are installed on the back face of the stomatoscope to prevent saliva from entering the battery storage cavity to cause electric leakage.

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...

[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 for inspection and wiping. The existing oral mirrors are inconvenient to adjust the angle, which reduces the efficiency of inspection.
