CAD of palatal metal plate of upper complete denture / 实用口腔医学杂志

ABSTRACT

Objective: To reconstruct 3D shape of upper edentulous jaw f or the design of a digital model of palatal metal plate of upper complete dentur e. Methods: Standard edentulous jaw models were measured with a numerical controlled miller and a new data collection system by cutting and sca nning layer-by-layer, the 3D shape of the models was reconstructed by image pr ocessing with special software. Based on these data, a palatal metal plate of u pper complete denture was designed by using SURFACER softerware.Results: Data of upper edentulous jaw models and a palatal metal plate of upper c omplete denture were obtained.The error between basal surface of the plate base and uper endentulous jaw was 0.0245 ?0.0267 mm. Conclusion:E dentulous jaw can be reconstructed by three-dimensional measurement, the design ed palatal metal plate of upper complete denture will be helpful to the further Laser Solid Forming.
