Part‐Digitizing System of Impression and Interocclusal Record for Complete Denture Fabrication

Few studies have reported the application of digital technology to removable dentures, particularly for the process of impression and interocclusal recording for complete denture fabrication. This article describes a part‐digitizing system of impression and interocclusal records for complete denture fabrication. The denture foundation area in an edentulous mouth, including the border areas and residual ridge, is outlined by tracing the surfaces with a 3‐D pen‐type digitizer. Specialized trays for final impressions and interocclusal records were generated using computer‐aided design and manufactured using the digital data. Final impression and interocclusal records were carried out using these specialized trays. The computer‐aided method using preliminary digital impressions and specialized trays would be feasible for clinical use for complete denture fabrication.
