Dental positioning stent, and manufacturing method, using method and components for the same

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.

What is claimed is: 
     
         1 . A dental positioning stent, manufactured by the following method:
 manufacturing a tooth mold according to teeth in a mouth of a patient, selecting a preset implant position of an implant on the tooth mold, and disposing a false tooth model 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; and   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.   
     
     
         2 . The dental positioning stent according to  claim 1 , the manufactured method further comprises:
 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.   
     
     
         3 . Components used in a dental positioning stent, for using with a drill, the components comprising:
 a positioning aid, mounted in a positioning stent, wherein a center of the positioning aid has a positioning hole running through the positioning aid; and   a slider, sliding into the positioning hole to guide a drill.   
     
     
         4 . The components according to  claim 3 , wherein the drill is an initial drill, and the slider is a positioning sleeve in the shape of a hollow sleeve to guide the initial drill to drill a guide hole. 
     
     
         5 . The components according to  claim 3 , wherein the drill is an enlargement drill or a guide drill, and the slider is a reaming sleeve in the shape of a hollow sleeve to guide the enlargement drill or the guide drill to ream a guide hole. 
     
     
         6 . The components according to  claim 3 , wherein the drill is an enlargement drill or a guide drill, the enlargement drill and the guide drill respectively has a cutting portion and a shank portion, the slider is a positioning cap comprising a tube portion and a flat portion, the flat portion covers one end of the tube portion having a drill bit guide hole in a center of the flat portion, and the positioning cap guides the enlargement drill or the guide drill, such that the shank portion passes through the drill bit guide hole, and the cutting portion reams the guide hole. 
     
     
         7 . The components according to  claim 6 , further comprises:
 a shield, comprising a concave side and a convex side opposite to the concave side, the concave side faces the cutting portion of the drill, and the shield is disposed on the cutting portion to prevent the cutting portion from damaging the positioning cap.   
     
     
         8 . Components used in a dental positioning stent, comprising:
 a positioning aid, mounted in a positioning stent, wherein a center of the positioning aid has a positioning hole running through the positioning aid;   a drill, comprising a cutting portion and a shank portion; and   a slider, sliding into the positioning hole to guide a drill, wherein the sum of the heights of the slider and the positioning aid is essentially greater than or equal to the length of the cutting portion of the drill.   
     
     
         9 . Components used in a dental positioning stent, for reaming the upper end of a guide hole, the components comprising:
 a guide drill, comprising a cutting portion, a shank portion connected to the cutting portion and a cylindrical portion extending from the top of the cutting portion, and the top of the cutting portion is flat, such that after the cylindrical portion is placed in advance into the guide hole, the cutting portion reams the upper end of the guide hole.
