Problems solved by technology

Since the implant planning is completed based on 3D digital images, most of the data are virtual drawing data or digital data, which are difficult to accurately present on the guide plate 11, and can only be made more accurate and correct after repeated scanning and correction. The guide plate 11 makes the guide plate 11 made by the existing manufacturing method less accurate, and has the disadvantages of relatively poor manufacturing efficiency and high manufacturing cost

Embodiment Construction

[0041] Below in conjunction with embodiment the present invention is described in detail:

[0042] refer to image 3 A first preferred embodiment of the manufacturing method of the dental implant surgery guide plate of the present invention comprises the following steps:

[0043] Step 201 is implant planning, using the dentist to perform implant planning on the 3D stereoscopic model obtained after the patient's oral cavity tomography, and obtain and build a digital model with implant planning data, such as Figure 17 As shown, it is a schematic diagram of the digital model image with the dental implant planning data.

[0044] Step 202 is to obtain the oral cavity model, copy the shape of the patient's oral cavity, and make such Figure 7 A solid plaster model is shown2.

[0045] refer to Figure 8 , step 203 is the positioning of the solid plaster model, and the solid plaster model 2 obtained in step 202 is fixed to a solid processing jig 3 by a fixing method selected from...

Abstract

The invention relates to a method for producing a tooth implantation surgical guide stent, which comprises the following steps: performing a tooth implantation plan; obtaining an oral entity plaster model; positioning and scanning the entity plaster model; positioning information of the tooth implantation plan on a digital plaster model obtained by scanning; positioning the digital plaster model in a scheduled processing position by processing software; putting the entity plaster model in the processing position to perform drilling processing and present the information of the tooth implantation plan on the entity plaster model; installing an auxiliary implanting piece; and forming the surgical guide stent with a plurality of guide holes on the processed entity plaster model by thermoplastic materials in fit with a rollover forming method or a vacuum forming method. Thus, the method can be used for producing more precise surgical guide stents, and has the characteristics of time saving, labor saving and production cost reduction.

Description

technical field [0001] The invention relates to a method for manufacturing a guide plate, in particular to a method for manufacturing a guide plate for dental implant surgery. Background technique [0002] During the traditional artificial dental implant surgery, patients are prone to bleeding, swelling, pain and other phenomena. In order to avoid the occurrence of the above-mentioned phenomena, the current accurate head computerized tomography scan and computer software diagnosis can already be used. The three-dimensional model of the skeleton and the direction of important nerves can be viewed without surgery. At the same time, the dentist can evaluate the patient's bone environment and judge the quality of the tooth bite, so it can simulate surgery on the computer to implant artificial implants. , to ensure that important nerves and blood vessels are avoided during dental implant surgery, which greatly improves the safety of the operation and provides better protection fo...
