Full-Arch Implant-Supported Rehabilitation Using Reverse Scan Technique: A Case Report.

Abstract

This was a case report successfully employing the reverse scan technique. A 72-year-old male patient desired to restore his teeth in both jaws. Clinical examination revealed the presence of several remaining teeth with poor prognosis due to significant bone loss and mobility. The treatment plan involved extracting these teeth, placing 4 implants in the maxilla and mandible, and fitting an interim immediate loading prosthesis. Full-thickness flaps were raised during surgery, and the remaining teeth were extracted. Implants and multiunit abutments were placed, followed by impressions and the recording of the interjaw relationship using index dentures. After 6 months of osseointegration, the reverse scan technique was employed, using light silicone, reverse scan bodies, and extraoral scanning to capture implant positions, soft tissue profiles, and prosthesis shapes. Titanium frames were machined for the final prostheses-monolithic zirconia for the maxilla and zirconia crowns with composite gingiva for the mandible. These were delivered after confirming the fit, aesthetics, and occlusion. The technique enhanced patient comfort, minimized chair time, and ensured the quality of the prosthetic outcome.
