Introduction of a technique for fabrication of an implant-supported fixed temporary prosthesis

In fully edentulous patients, reconstruction with implant-supported fixed prosthesis is a complicated treatment. In conventional technique, after the placement of the implants, fixed temporary prosthesis is fabricated with no consideration of the removable prosthesis that the patient has used yet. Therefore, the logical relation of the phases of treatment is lost and the points such as vertical dimension occlusion and centric relation are not recorded exactly. The purpose of this article is to introduce a technique in which a fixed temporary prosthesis is fabricated by use of patient's full denture. Case Report: In this study, a 60-year-old patient with complete edentulous in the mandible was referred to Dental School. He has used a complete jaw denture in the mandible. The complete denture especially in the lower jaw has caused destructions to the remaining ridge. Due to the patient's condition and the existing circumstances, the treatment design of implant-supported fixed prosthesis was accepted by the treatment team. Prior to the surgery, assessments of the bone quality and quantity, force factors, the number of the implants, their lengths and angles were done and the complete denture was converted to implant-supported fixed temporary prosthesis. The fabrication of conversion prosthesis was introduced with implant-supported metal ceramic restoration.
