DENTAL POSITIONING STENT, AND MANUFACTURING METHOD, USING METHOD AND COMPONENTS FOR THE SAME
First Claim
1. A manufacturing method for a dental positioning stent, used for positioning an implant to mount a false tooth on the implant, the method comprising:
- manufacturing a tooth mold according to teeth in a mouth of a patient, selecting a preset implant position of the implant on the tooth mold, and disposing a false tooth model in equal proportion to the false tooth on the tooth mold;
selecting a preset slice plane passing through the preset implant position, and slicing the tooth mold and the false tooth model along the preset slice plane;
fixing two markers in the preset slice plane on two sides of the tooth mold and the false tooth model respectively, wherein the markers are not penetrated by an X-ray;
covering the markers, the false tooth model, and a part of the tooth mold surrounding the markers and the false tooth model with a shaping agent to form a positioning stent, wherein the shaping agent comprises a resin polymer and a developer;
putting the positioning stent on the teeth in the mouth to perform tomography imaging, so as to acquire a slice image of the preset slice plane;
pasting up the slice image on a slice plane of the tooth mold in equal proportion;
selecting a diameter, a length, an implant depth, and an implant angle of the implant according to the slice image pasted up on the tooth mold and a profile of the false tooth model; and
mounting a positioning aid having a positioning hole in a corresponding position of the positioning stent to the implant, wherein when the positioning stent is placed in the mouth of the patient, a slider slides into the positioning hole to guide a drill.
