A posture adjustment device for three-dimensional measurement of dental models

Abstract

The invention discloses a gesture regulating device for a three-dimensional measurement of a dental cast. The gesture regulating device comprises a clamp part, a platform part and a bracket part; the clamp part is arranged on the upper surface of the platform part; the bracket part is of a U-shaped frame supporting structure; the platform part is arranged on the upper surface of the bracket part; the clamp part comprises a calibrating clamp, an adapting clamp and multiple magnets; the calibrating clamp is used for clamping a planar side of a dental cast; the adapting clamp has a curve profile which is used for clamping a curve side of the dental cast; the magnets are arranged in a cavity body at the bottoms of the calibrating clamp and the adapting clamp, and surfaces of the magnets which are exposed outside the cavity body are horizontal with the bottom surfaces of the calibrating clamp and the adapting clamp; the platform part comprises a turning motor, a turning motor base, a pair of couplings, a left turning shaft, a left turning side plate, a carrying platform, a right turning side plate, a pair of turning shaft bases, a right turning shaft, a pair of turning fixing rings, and a pair of turning bearings. According to the gesture regulating device, a gesture of the dental cast is automatically regulated, thereby achieving three-dimensional measurement in multiple angles.

Description

technical field [0001] The invention belongs to the field of oral restoration, and more particularly relates to a posture adjustment device for three-dimensional measurement of dental molds. Background technique [0002] Today, 1 / 4-1 / 3 of my country's population suffers from oral diseases of varying degrees, and the development of oral restoration technology plays an extremely important role in promoting a healthy life. The traditional dental restoration technology adopts hand-made prosthesis technology, which mainly adopts methods such as engraving wax type, lost wax casting, and porcelain denture production. This method has cumbersome procedures, long processing time, and low precision of the prosthesis. After several times of follow-up visits and adjustments, he could adapt, prolonging the pain and treatment time of the patient. [0003] In the early 1970s, people began to try to introduce CAD / CAM technology into dental restoration technology. Today, the mature dental C...

Problems solved by technology

[0005] The inventor's patent "A Dental Model Measuring Device" with the application number of 201110088369.9 once involved a dental model attitude adjustment device, but the turning and rotating actions of the device need to be manually adjusted, and then locked with screws. The operation is cumbersome and the corner is not Continuous and imprecise, the flip angle is limited by the arc track, and there will still be angles that cannot be scanned during the scanning process

In addition, the dental model is fixed by locking screws, which is troublesome to clamp, and it is difficult to reliably clamp the irregular dental model
