Abstract
The present case report describes a technique to convert an interim mandibular complete dental prosthesis into a digitally designed and additively manufactured implant overdenture prosthesis. A patient had two dental implants placed, an interim complete denture, and a soft reline procedure completed. After implant osseointegration, existing healing abutments were removed, a functionally generated reline impression with polyvinyl siloxane impression material was made. Using an intraoral scanner, a 360-degree optical scan was obtained of the relined interim prosthesis. A new prosthesis was digitally designed using the optical scan, additively manufactured, and housings picked-up intraorally to create an implant-retained overdenture.
