Abstract

Recently three-dimensional (3D) printed complete dentures are becoming more widely recognized as one of the treatment options for the edentulous patients. Korean National Healthcare, however, has not yet approved the application of the 3D printed dentures, and in the cases where the dentures should be refabricated, the conventional fabrication process needs to be entirely repeated. However, during the conventional process, the digital scan data of some key steps could be easily obtained. In this clinical case, using these data, a new pair of 3D printed dentures that improved the limitations of the first conventional dentures were successfully fabricated.
