Abstract

A method for digital filing and production of dental prosthesis and prosthesis and its teaching training, the method mainly includes the following steps: pre-operative scanning (110) establishing the first digital model file (121), optical positioning and turning treatment (130 ), and establish the second digital model file (122) during the turning process; the solid model calculation (140) reversely establishes the patient's autologous crown model file (150); and manufactures the fixed denture (200), combining the first Two digital model files (122) and autologous crown model files (150) to make fixed dentures that meet the patient's needs, so that the inner structure of the crown of the fixed dentures can be closely combined with the abutment body, and can be determined according to needs To preserve the original appearance of the crown. According to the above-mentioned method, the tooth model of the teaching digital model file can be used for the teaching and training of the trainee.

Description

technical field

[0001] The present invention relates to a digital file and production method of dental prosthesis and prosthesis, and a production method of dental prosthesis and prosthesis. Background technique

[0002] In the treatment of dental caries, when the permanent tooth is damaged, it will not be able to grow new teeth after extraction, so there is a treatment called prosthetic prosthetics, which use fixed dentures (commonly known as crowns and bridges) to The natural teeth are turned and ground as the abutment teeth, and then a metal or metal-combined ceramic fixed denture-crown or bridge is glued on the outside of the abutment teeth.

[0003] The crown is suitable for severe tooth decay or trauma and other reasons that cannot be repaired by traditional filling methods. The tooth is protected by a crown after an appropriate amount of turning and repairing, so that it can continue to be used without extraction. Root canal treated teeth are severely damaged, so in ...
