Method for manufacturing guide plate for growing positioning and orientating of dental

Abstract

The invention relates to a fabrication method for a dental implanting positioning and orienting guide plate. The fabrication method has the detailed steps as follows: wax teeth in coincidence with the false tooth shape are modeled by wax at the missing tooth zone of the plaster modelIof a patient; the plaster with wax teeth are turnover into a total plaster model II; the insertion path of implanting screws are determined according to the positions of the teeth and the shapes of the alveolar bones; holes are bored downwards from the occlusal faces of the teeth needing to be repaired on the modelIIby a fissure bur to cause the holes to be communicated the whole model; the bored model IIis placed in a vacuum pressed film machine to be made into a vacuum pressed film denture base which forms a tubular channel in the hollow hole; the vacuum pressed film denture base is taken down from the modelIIto trim; the vacuum pressed film denture base is put on the modelI, the bottom part of the tubular channel is trimmed to cause the lowest point to be slightly higher than the modelI, and the trimmed vacuum pressed film denture base is the dental implanting positioning and orienting guide plate. The positions and the direction of the implanting screws can be determined before operation by the fabrication method, and the implanting screws can be accurately moved to the oral cavity of the patient in the operation.

Description

technical field [0001] The invention relates to a manufacturing method of a dental implant positioning and orientation guide plate. Background technique [0002] In dental implant surgery, the positioning guide plate made before the operation can help the doctor roughly determine the position of the implantation screw during the operation. However, this guide plate can only roughly determine the initial point of implantation, and cannot determine the insertion direction of the implantation nail. The direction of the implanted nails can only be roughly determined by the doctor through visual inspection, which increases the error of the operation and reduces the stability of the implanted nails during repeated insertion and adjustment. Contents of the invention [0003] The object of the present invention is to provide a method for making a dental implant positioning and orientation guide plate which is easy to manufacture and can not only determine the implant site but als...

Problems solved by technology

However, this guide plate can only roughly determine the initial point of implantation, and cannot determine the insertion direction of implantation nails.

The direction of the implanted nails can only be roughly determined by the doctor through visual inspection, which increases the error of the operation and reduces the stability of the implanted nails during repeated insertion and adjustment.
