Prosthetic replacement is often necessary to restore function and aesthetics in the periodontally compromised dentition.Fixed bridges can be placed and successfully maintained on a minimal number of abutment teeth with reduced periodontal support, provided the prosthodontic treatment is planned and performed in a proper way.Establishing an occlusion in such conditions are much more than designing the occlusal surfaces of posterior teeth.A favourable distribution of the masticatory load along the entire arch will prevent overloading of abutment teeth with reduced periodontal support.To a great extent the success of prosthesis depend on oral hygiene maintenance by the patient.
