3D facial universal inter-maxillary relationship recording device for fully edentulous jaws

Abstract

The invention discloses a complete edentulous jaw 3D face universal inter-jaw relation recording device. The complete edentulous jaw 3D face universal inter-jaw relation recording device is formed bya swinging plate, a first baseplate, a second baseplate, an upper jaw plate, a lower jaw plate, two universal components and a horizontal detector. Each universal component is formed by a ball socketcomponent with a ball socket part and a ball head component with a ball part. Each ball socket component is fixedly installed at the top surfaces of the first and second baseplates, each ball head component is fixedly installed on the bottom surfaces of the swinging plate and the upper jaw plate, so the ball part of each ball head component is accommodated and positioned in the ball socket part ofeach ball socket component, and the horizontal detector is installed on the connection part of the swinging plate. So, the horizontal adjustment and correction can be accurately and conveniently performed, the occlusal point distribution of false teeth and the relative relation of the upper and lower jaws and the positioning of an occlusion plane can be rapidly analyzed, and thereby complete reconstructed false teeth according with a physiological function are produced.

Description

【Technical field】 [0001] The present invention relates to a full edentulous 3D facial universal inter-maxillary relationship recording device, especially a time-saving and fast full edentulous 3D facial universal inter-maxillary relationship recording device in the process of restoring dentures. 【Background technique】 [0002] When people have lost all their teeth, or have to extract their teeth due to factors such as drug treatment, accidental atrophy, disease or old wear and tear, they generally need to install replaceable artificial teeth. The most common form of complete dentures is the form of removable dentures, which usually include a whole set of upper and lower teeth, and the size and shape of the complete denture are adjusted and then installed on the upper and lower jaws of the patient. On the soft tissue of the oral cavity, it is used for the reconstruction of oral and dental functions. [0003] Today, due to the advancement of materials, dentures are stronger, ...

AI Technical Summary

Problems solved by technology

[0004] Before recording the dynamic occlusal relationship path, the occlusal plane of the patient must be established first to obtain a reference path. However, the conventional technology is to take out the upper and lower jaw models and the vertical height of the occlusal position in the rest position, which cannot be accurately measured in the patient's mouth. Therefore, it is impossible to analyze the distribution of the occlusal points of the dentures, the relative relationship between the upper and lower jaws, and the positioning of the occlusal plane; obviously, there is a need for further improvement of the above-mentioned deficiencies.
