Rotary ultrasonic-assisted tooth grinder

Abstract

The invention relates to a rotary ultrasonic-assisted tooth grinder. A grinding head assembly is connected with an ultrasonic vibration system to generate longitudinal vibration; the grinding head of the grinding head assembly is further driven by a flexible shaft to rotate. The rotary ultrasonic-assisted tooth grinder is integrated with the characteristics of an ultrasonic tooth cleaner and a traditional tooth grinder, and is capable of realizing either high-speed rotation or ultrasonic vibration; as a result, the tooth grinding and cleaning efficiency can be improved, and the tooth grinding and cleaning effect also can be improved; in other words, the teeth are low in surface roughness, high in surface finish and low in damage. The housing of the tooth grinder is designed into a handle shape and can be held and operated by a doctor conveniently.

Description

technical field [0001] The present invention relates to a medical device, more specifically, to a rotary ultrasonic assisted teeth grinding machine. Background technique [0002] With the improvement of people's living standards, the requirements for the quality of life are getting higher and higher, and the health of the teeth is also paid more attention to. Having a white and healthy tooth is the pursuit of many people. However, in daily life, bad habits such as not brushing teeth after meals and smoking will leave stains on the surface of the teeth, making the surface of the teeth yellow or even black. This not only seriously affects the appearance of the teeth, but also causes bad breath, and even breeds bacteria, which affects the health of the teeth and the body. [0003] With people's pursuit of beautiful teeth and the strengthening of awareness of dental health protection, in recent years, more and more people regularly go to dental clinics to wash and grind their t...

AI Technical Summary

Problems solved by technology

Teeth grinding machines use the main shaft to drive the molar burs to perform rotational motion to grind the tooth surface. Although the grinding head rotates at high speed, the linear speed of the grinding head surface is still very small due to the small diameter of the molar burs, and the enamel on the tooth surface The hardness of the layer is very high, and it is difficult to process. After processing, the surface roughness is large, and it is easy to produce large microscopic damage cracks, which will affect the health of teeth.
