Embodiment 1

[0027] Example 1: A denture scanning positioning fixture (see attached figure 1 , Attached figure 2 ), including the marking point frame 1. The marking point frame is an isosceles trapezoidal frame structure, and the clamping cavity 2 is formed in the marking point frame. The upper surface and the four outer sides of the marking point frame are provided with several marks for scanning splicing and positioning Point 3. The marking point can be convex or concave. Four connecting columns 4 are arranged on the lower surface of the marking point frame, and two connecting columns are arranged at the upper and lower bottom edges of the marking point frame of the isosceles trapezoidal frame structure. The two opposite sides of the marking point frame are provided with clamping holes 5 that penetrate into the clamping cavity. One clamping hole is arranged on one side of the upper bottom side of the isosceles trapezoidal marking point frame with a smaller width, and two clamping holes a...

Abstract

The invention discloses a scanning positioning clamp for a false tooth. The invention aims to overcome the defects of inconvenience in scanning, positioning and clamping the false tooth and low precision of a false tooth scanning three-dimensional model. The scanning positioning clamp for the false tooth comprises a mark point frame, wherein a clamping chamber is formed in the mark point frame; a plurality of mark points for scanning, splicing and positioning are formed on the upper surface and side walls of the mark point frame; a plurality of connecting columns are arranged on the lower surface of the mark point frame; clamping holes which penetrate through the clamping chamber are formed in two opposite sides of the mark point frame. The scanning positioning clamp for the false tooth is capable of bringing convenience to the operations of scanning, positioning and clamping the false tooth and increasing the precision of the false tooth scanning three-dimensional model.

Description

Technical field [0001] The invention relates to a denture scanning technology, more specifically, it relates to a denture scanning positioning fixture which is beneficial to improving the scanning accuracy. Background technique [0002] The automatic denture 3D scanner is a high-end 3D scanner specially developed for CAD / CAM applications in the dental industry. It is equipped with an automatic rotating platform and the latest surface scanning technology. It is easy to operate and can easily obtain single teeth, full teeth, and scanned implants. , Occlusal state, high-precision, high-definition three-dimensional data of plaster models or impressions. The data can be directly used in the field of CAD / CAM digital dentistry. It is widely used in professional fields such as fillings, tooth restoration and correction, and education. Among them, scanning implants and multiple bridge dentures requires higher scanning accuracy. At present, the plaster mold fixture supporting the denture ...
