Axial surface polymerization degree checker for dental prosthodontic tooth preparatory body

Abstract

The invention belongs to the technical field of medical equipment, and in particular, relates to an axial surface polymerization degree checker for a dental prosthodontic tooth preparatory body, wherein the checker comprises an adjusting assembly and a checking assembly. The adjusting assembly comprises a handle, a sliding block and a button; the sliding block is slidingly connected with the handle, and the button is located on the top surface of the sliding block; the top surface of a mobile arm is fixedly connected with the sliding block, and the sliding block is slidingly connected with thehandle; the mobile arm is adjusted by sliding the sliding block, and the distance between the mobile arm and a fixed arm can be adjusted according to the size of teeth of patients in different age groups; the mobile arm can be adjusted by controlling the button at any time when the patients are examined, so as to check different teeth of the patients. A spring is fixedly connected between the mobile arm and the fixed arm. The spring can apply tensile force on the mobile arm and the fixed arm, so that the mobile arm and the fixed arm always keep fit with the teeth of the patients, so as to beconvenient for doctors to observe and judge.

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. It is necessary to pass the inspection of the degree of polymerization of the axial surface of the oral restorative tooth preparation machine to examine the teeth. [...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing dental prosthetic tooth preparation axial surface polymerization degree checker has a simple structure. After the distance between the two inspection arms is adjusted, it needs to be fixed by bolts and nuts. When inspecting different teeth of the patient, it needs to be adjusted several times. Adapting the two inspection arms to the teeth is time-consuming and labor-intensive to use

[0005] 2. The structure of the existing dental prosthetic tooth preparation axial surface polymerization degree checker is inflexible. The two inspection arms need to be fixed by bolts and nuts after the distance is adjusted. In actual use, the shaking of the doctor's arm and the slight shaking of the patient It will cause the two inspection arms to be unable to keep fit with the teeth all the time, making the measurement accuracy lower
