Research on and Application of Digital Design Framework of Full-coverage Crowns and Bridges Denture

摘要

Digital restoration of the full-coverage crowns and bridges mainly consists of the connector generating and model fusion. Through defining the section template, the default connector can be generated under the guide of the idea of skin, whose curve can be edited by the control points. If the connector meets the requirements, the connector's boundary should be projected onto the adjacent full-coverage crowns or bridges. The inner regions are tailored by the projection curve, and finally the full-coverage crown, bridge and connector are fused by the mean of bidirectional sew algorithm. And the restoration of the full-coverage crowns and bridges denture can be obtained by smoothing the transition area. It's good quality, high efficiency and can meet the clinical demand.
