Example Embodiment

[0042] Aiming at the problem that the existing tooth inclination measuring device and method are too complicated, this solution proposes a device for tooth inclination measurement, which can simply and effectively measure the tooth inclination, and can measure multiple positions and multiple Angle of inclination of teeth.

[0043] A device for measuring the inclination of tooth cusps, comprising a model plate 9 for fixing a tooth model 26, a clamping box 13 with an adjustable position is arranged above the model plate 9, and a plurality of clamping boxes 13 are arranged side by side The measuring plate 6 can move in a direction close to the tooth model 26 and contact the teeth on the tooth model 26 at the lower end of the measuring plate 6.

[0044] The design principle of the present invention is that since the occlusal surface of the tooth is composed of curved surfaces, the tooth surface can be regarded as composed of line segments connected by countless points. In this solutio...

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 the tooth tip. Background technique [0002] Cracked tooth, also known as the cracked tooth syndrome (CTS), is more common in clinical practice. Data shows that cracked tooth is the third cause of tooth loss. Cracked teeth cannot be treated in time because they are not easy to find in the early stage, which has become an important cause of tooth splitting in middle-aged and elderly people. [0003] Teeth wear and tear from the time they erupt and chew food, and wear and tear continues to increase with age. The teeth of middle-aged and elderly people will have different degrees of wear. Some teeth show loss of enamel, increase in cusp inclination, and decrease in cusp inclination angle, which leads to an increase in the horizontal component of force applied to the occlusal surface, which become...
