This article describes a technique for fabricating a provisional fixed prosthesis, the conversion prosthesis, and is constructed immediately following the abutment connection. The conversion prosthesis provides a fixed prosthesis immediately following stage 2 surgery with improved function, stability, and distribution of load; it protects the sutured mucosa; serves as a prototype for the final prosthesis; can be used as a verification jig; preserves the original vertical dimension of occlusion; aids in obtaining and transferring the interocclusal record; assists long-term patient maintenance; and reduces treatment visits. The advantages of this technique are numerous for the patient, the restorative dentist, and the laboratory technician. Most important, however, the conversion prosthesis provides superior patient comfort and satisfaction and improves the quality of care provided.
