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 develop an original dental CAD/CAM system to 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...
