  • Dental positioning stent, and manufacturing method, using method and components for the same
    Patent number: 9022782
    Abstract: A dental positioning stent for drilling an implant hole and a manufacturing method, a using method and components for the same are provided. The manufacturing method includes: slicing a tooth mold and a false tooth model along a preset slice plane; fixing two markers in the preset slice plane on two sides of the false tooth model respectively; covering the markers and the false tooth model with a shaping agent to form a positioning stent; putting the positioning stent on the teeth in a mouth to perform tomography imaging to acquire a slice image of the preset slice plane; mounting a positioning aid having a positioning hole in the positioning stent according to the slice image pasted up on the tooth mold to guide an initial drill. A dental positioning stent for tomography imaging, and a manufacturing method, a using method, and components thereof are provided.
