A Technique for Restoring Severely Resorbed Edentulous Mandible with a Computer-aided Design and Computer-aided Manufacturing Surgical Guide and an Implant-supported Fixed Dental Prosthesis in Two Days.

AIM: The aim of this report is to describe a technique, in which a severely resorbed edentulous mandible was restored with computer-aided design/computer-aided manufacturing (CAD/CAM) surgical guide and an implant-supported fixed dental prosthesis in two days. BACKGROUND: The quality of life of edentulous patients is generally restricted due to functional and psychosocial problems associated with complete dentures. These issues become worse over time due to ongoing bone resorption. Implant-supported prostheses have been utilized to overcome these problems. CASE DESCRIPTION: A 79-year-old patient with a severely resorbed edentulous maxilla and mandible presented to our clinic. After the cone beam computed tomography (CBCT) scans were performed, five implants were virtually placed via a 3-dimensional software. Then, a CAD/CAM surgical guide was fabricated with a stereolithographic method. Her mandible was restored with five implants by using the CAD/CAM surgical guide and the implant-supported prosthesis with CAD/CAM titanium framework in 2 days. CONCLUSION: The severely resorbed edentulous mandible was successfully restored with five dental implants, and the implant-supported fixed dental prosthesis via the CAD/CAM milled titanium framework. CLINICAL SIGNIFICANCE: The technique using software and hardware portrayed in this report may be a feasible option to restore similar patients if it is executed by trained restorative dentists adhering to strict guidelines.
