Immediate complete denture rehabilitation using combined digital-functional impression technique and three-dimensional-printed occlusal templates

Abstract

Integration of digital technology in prosthodontics enables precise and predictable outcomes. A hybrid digital-conventional workflow combines the accuracy of digital protocols with the reliability of traditional techniques. A 46-year-old male with generalized aggressive periodontitis required full-mouth extraction and immediate dentures. Intraoral scans were captured at the existing vertical dimension and used to design custom trays in EXOCAD. The trays, three-dimensional-printed with windows for natural teeth, facilitated border molding and final impressions for soft tissue capture. These impressions were digitized, superimposed on intraoral scans, and used to create a virtual model, perform virtual extractions, and fabricate definitive dentures. The digital approach improved patient comfort, accelerated planning, and enhanced accuracy, while conventional steps ensured an optimal peripheral seal in scanner-inaccessible areas. The technique delivered a functionally stable and esthetically satisfactory outcome.
