The use of dental implants for replacement of teeth has become a routine procedure also in the periodontally compromised patient .The presence of periodontal inflammation and periapical infection often delay the placement of bone grafts as well as dental implants. When transitioning from a failing dentition to complete-arch implant rehabilitation, significant treatment planning is required. In this report a patient with severe chronic periodontitis underwent a full mouth reconstruction with staged approach. The oral function and esthetics was restored with fixed screw retained implant supported prosthesis. However supportive periodontal therapy becomes the most important aspect for survival of complex prosthesis.
