The Rehabilitation of Edentulous Mandible with the Use of All-on-Four Implants concept: a case report

Abstract

This case report presents a case of the "all-on-4" implant treatment concept of the highly resorbed mandible ridge. The use of 2 angled implants directed toward the midline of the mandible at 30 degree angle provided the advantage of increased implant length and adequate insertion torque for prosthestic rehabilitation. In this case, the Toronto bridge framework was prepared with cast metal alloy in conventional manner & PFM crown  were cemented onto the framework to enhance esthetic and to reduce cost factor.
