Digital model taking technology for tooth implantation

Abstract

The invention discloses a digital model taking technology for tooth implantation. The technology specifically comprises the following steps that firstly, oral cavity examination is performed on a patient; secondly, the oral cavity of the patient is cleaned; thirdly, a doctor embeds an implant into a position where the patient lacks a tooth, and an impression cap is placed at the cuff of the implant in the oral cavity of the patient; fourthly, an occlusal tray is placed in the oral cavity of the patient; fifthly, three-dimensional scanning is carried out through a three-dimensional scanner, a 3D model is printed, and finally a suitable denture is made. According to the invention, the special digital impression cap is fixed to the cuff of the implant in the mouth of the patient, and then thedoctor can take a model according to a conventional model taking method without a transfer rod, a substitution or a healing cap; after the model is taken, the tray is sent to a technician for scanning and printing the resin model, and then the resin model is machined according to a normal repair body manufacturing flow. The technology has the advantages that the operation is simple, the accuracyis high, the patient feels no pain, and particularly digital repairing can be carried out.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a digital impression-taking technique for dental implants. Background technique [0002] Dental implant is a kind of edentulous repair method based on the lower structure implanted in bone tissue to support and retain the upper tooth restoration, including the lower supporting implant and the upper restoration, which are used to treat tooth defects and Deletion is the best oral restoration technology at present, with the characteristics of strong function, no teeth grinding, and good retention; [0003] One of the traditional restoration methods is fixed teeth restoration, and the other is dental implant restoration. The restoration method of fixed teeth is to directly put the tray with silica gel into the mouth, and the teeth occlude. Dental implant restoration methods are further divided into general implant restoration methods and intraoral scanning impression restora...

AI Technical Summary

Problems solved by technology

The general process of implant impression taking is as follows: implant the implant into the edentulous part of the patient, and then put in the healing screw. After two to three months, take out the healing screw, put it into the healing cap, and let the gums follow the healing cap. After a week of growth, after the growth is complete, put the silicone tray with the transfer rod into the patient's mouth for occlusal, then the transfer rod is screwed into the implant, wait a few minutes, take out the tray, and then make a plaster denture model according to the sampling, and then For follow-up work, this method uses a transfer rod, which is very long, so it is very troublesome to operate. In addition, this process is carried out in the patient's mouth, so the patient is very painful durin
