Problems solved by technology

In the prior art, the method of indirectly constructing the connecting body by increasing the shape of the basal crown is used, in which the retainer needs to be enlarged in a certain direction, which itself modifies the shape of the tooth and will inevitably cause errors

Abstract

The invention discloses a false tooth bridge connecting body digital generating method, which comprises the following steps of outputting a connecting body model according to connecting body parameters; calculating the placing position of the connecting body; performing positioning processing on the connecting body model. The selection can be made according to the shape of the near distant and middle surface of a given tooth; an elliptic cylinder connecting body or a triangular prism connecting body can be selected; according to different shapes of the concrete tooth, the connecting body crosssection shape can be further changed; the operation is the second selection. For example, the elliptic cross section can be changed into the round cross section according to the conditions; the sizeof the vertex angle of an isosceles triangle can be changed in real time according to the sharp degree of the cuspid tooth; the cross section of the connecting body is completely controlled by the user; the cross section control is very flexible; errors can be effectively reduced; the connecting body model generation positioning realization is simple; the efficiency is higher. The method can be widely applied to false tooth modeling.

Description

technical field [0001] The invention relates to the technical field of denture digitalization, in particular to a digital generation method of a denture bridge connector. Background technique [0002] In the pontic repair module of the denture restoration CAD / CAM system software, the pontic model must be connected to the retainer through a connecting body in order to function. This is because the pontic model is just a single tooth model. Without a reliable support to connect it closely with the adjacent teeth on the left and right sides, the pontic model cannot be fixed in position, which is meaningless. In order to fix the bridge model, it is necessary to design a connecting body to connect the bridge body with the retainer. The design of the connecting body must first ensure its strength requirements. According to the standard of prosthodontics, when the cross-sectional area of ​​the connecting body is between 4 and 10mm2, the strength meets the requirements. When editi...
