The fixed bridge framework is an important part of prosthodontics. We design a fixed bridge framework in computer with our own original dental CAD software. The 3D data of the abutment teeth is measured by ATOS II 3D scanner. Then the coping crowns are designed based on the implicit surfaces. An algorithm is presented to deform the bridge based on the interactive mesh editing technique, so that the...
In this paper we present a novel approach to build the standard crown database based on the sketch of the standard tooth, and then deform the crown to fit the patient using an efficient volumetric approach. Take example for the mandibular first molar, some key lines are collected from standard tooth pictures. Then we edit these lines to build the skeleton of the digital tooth model, and convert the...
In this paper we develop an original dental CAD/CAM system for design and manufacture the framework of PFM (porcelain fused to metal) fixed bridge in computer. Take example for the missing of the mandibular first molar, firstly, we use ATOS II 3D scanner to measure the 3D data of the abutment teeth which is used to design the coping crowns. Secondly, a relevant standard bridge is selected from the...
