Prosthodontic rehabilitation of resorbed mandibular ridges using guided all-on-four technique and implant retained overdentures-A case series.

Abstract

Continued residual ridge resorption in edentulous patients causes a great challenge in prosthetic rehabilitation by conventional denture. Retention and stability are greatly compromised in conventional dentures, especially if mandibular ridge is severely resorbed. Rehabilitation of such patients using dental implants has been proven as a successful treatment modality. With the evident of guided surgery, accurate and predictable implant placement can be achieved. This case series describes the prosthodontic rehabilitation of resorbed mandibular arches using guided all-on-four technique and implant retained overdentures.
