Method for produce digital tooth implantation planning auxiliary assembly

Abstract

The invention discloses a generating method for a digital tooth implantation planning aided component. The generating method is mainly as follows: the shape inside an disease oral cavity is copied and made into an oral cavity model, then the oral cavity model is scanned three-dimensionally to acquire a digital model of the oral cavity model, a digital model of the disease oral cavity, and a digital model of a hypodontia teeth model, and the digital model of the oral cavity model, the digital model of the disease oral cavity, and the digital model of the hypodontia teeth model are defined as a positioning object, a reference object and an adjoint positioning object respectively; then the positioning object and the adjoint positioning object are combined and a characteristic point is taken out, and the positioning object and the reference object are positioned by the characteristic point; and positioning data after the positioning of the adjoint positioning object and the adjoint positioning object are output together, and the output is the digital tooth implantation planning aided component.

Description

technical field [0001] The present invention relates to dental implant technology, in particular to a method for generating digital dental implant planning auxiliary components. Background technique [0002] According to, in the known dental implant technology, mostly emphasize on the assessment of bone environment, and ignore the situation of the quality of teeth butt bite. It is generally believed that the most important point is to consider the position of the implant in the jaw bone. If the axial deviation of the implant is too large after implantation, it can be corrected by using the angled abutment teeth. [0003] The above-mentioned practice is not the best practice. The reason is that the quality of the bone is important, but if the axial direction of the implant deviates from the occlusal reference plane, when the upper and lower teeth bite or bite the object, the impact on the implant will be reduced. It is not just an axial force, but also a bending moment. Exce...

Problems solved by technology

[0003] The above-mentioned practice is not the best practice. The reason is that the quality of the bone is important, but if the axial direction of the implant deviates from the occlusal reference plane, when the upper and lower teeth bite or bite the object, the impact on the implant will be reduced. It is not just an axial force, but also a bending moment. Excessive bending moment will easily destroy the bonding state between the implant and the alveolar bone, and will reduce the service life of the implant, or cause the implant to fail. Failure of osseointegration some time after surgery is done

[0004] Furthermore, if the axial deviation of the implant exceeds the range that the abutment teeth can correct after the implant is implanted, the occlusal surface will completely deviate after the denture is installed, and the occlusal function of the teeth will be completely lost.
