Gingival morphology-controlled design of the complete denture baseplate

A removable complete denture is still the main selection for edentulous patients. Over the last 5 years, digital technologies for producing complete dentures have rapidly developed. Nevertheless, the design method for the baseplate has become the bottleneck of digital complete denture technology development. In this study, we report a novel method for the generation of esthetic gingiva and polished surfaces of complete dentures that are driven by the feature curve, which can be conveniently modified using the gingival shape factor. A solid modeling method based on Poisson surface reconstruction is used to generate a high-quality baseplate solid. This method can aid dentists to realize the rapid design process of personalized esthetic baseplate. Finally, the experimental results verify that the method of digital design for the baseplate proposed is efficient and accurate (standard deviation <0.01 mm).
