Digitally guided interocclusal record technique utilizing a relined interim denture for complete arch implant-supported prostheses

Abstract

A straightforward and digitally integrated technique is described for registering the interocclusal relationship in edentulous patients treated with complete arch implant-supported prostheses. This approach utilizes the patient’s interim denture, adapted over the healing period, as a clinical reference base for transferring occlusal records. The prosthesis preserves the established vertical and centric relationships by selectively relieving the intaglio surface to allow passive seating over healing abutments, followed by intraoral relining. Further modification of the premaxillary region enables clear visualization of the anterior scan bodies during scanning. The relined and digitally modified prosthesis, referred to as the digital interocclusal capture appliance (DICA), is then scanned and incorporated into a digital workflow. This method provides a time-efficient, accurate, and patient-centered solution for transferring occlusal information from the interim removable prosthesis to a refined interim or definitive fixed restoration. It reduces chairside time, minimizes procedural steps, and enhances precision within a digitally guided complete arch workflow.
