" Converting a removable prosthetic option into fixed by using custom made non rigid connector "

Statement of the problem Many partially edentulous situations are present whereby the choice between a removable and a fixed partial denture lies within the delicate balance of a single standing abutment. This abutment is called as a pier abutment. If and when a fixed fixed prosthesis is given in such a case, the retainer over the pier abutment acts as a fulcrum and invariably leads to cement failure of the weak retainer. Purpose To design, prosthesis that is fixed in nature, but provides small movements within the retainer over the pier abutment so that two separate units distribute the stresses independently. Materials and Methods A clinical case whose mandibular arch presents a Kennedy’s class III situation with modification one. The two edentulous areas being separated by a pier abutment. Results The prosthesis has been functional since more than three years and the clinical and radiographic condition of all the abutments including the pier abutment suggests a successful fixed movable prosthesis. Conclusion A fixed movable prosthesis design involving a semi precision non rigid connector can be used in clinical situations where two edentulous areas are separated by a single abutment.
