A device for measuring the inclination of tooth cusps

Abstract

The invention discloses an apparatus for measuring the inclination of a tooth cusp. The apparatus comprises a model plate for fixing a tooth model, a position-adjustable clamping box is arranged above the model plate, a plurality of measuring sheets are arranged on the clamping box side by side, and the lower ends of the measuring sheets can move along a direction close to the tooth model, and contact with the tooth on the tooth model. The apparatus for measuring the inclination of the tooth cusp and a standardized measuring method have the advantages of simplicity, reliability, low cost, rapid data extraction speed, and visual property. The apparatus can measure the angle and scale of a sphere or a polyhedral angle, and realizes visual description by using a two-dimensional graph. The apparatus and the standard method established in the invention lay a foundation for subsequent researches of the form of the surface of the tooth.

Description

technical field [0001] The invention belongs to the field of oral clinical medicine and relates to a medical measuring instrument, in particular to a device for measuring the inclination of a tooth cusp. Background technique [0002] Cracked teeth, also known as the cracked tooth syndrome (CTS), are relatively common in clinical practice. Data show that cracked teeth rank third among the causes of tooth loss. Cracked teeth are not treated in time because they are not easy to be found in the early stage, which has become an important reason for the cracked teeth of middle-aged and elderly people. [0003] Teeth wear out from eruption to chewing food, and the wear continues to increase with age. The teeth of middle-aged and elderly people will have different degrees of wear and tear. Some teeth show the loss of enamel, the increase of the cusp slope, and the decrease of the angle between the cusp slope, which leads to the increase of the horizontal component force applied to ...

AI Technical Summary

Problems solved by technology

But the disadvantage is that there is no reliable measurement method, no corresponding measurement software, high cost and large radiation dose

Some scholars use CEREC3CAD / CAM to study the cusp slope of maxillary cleft molars. However, this method requires 3-DScanner professionals to operate, and there is no relevant software. meet clinical needs

[0006] The above-mentioned existing measurement methods are limited by the measurement points, have poor repeatability and large errors, so finding a simple measurement method has important clinical practical significance
