A technique for fabricating a provisional fixed prosthesis for an edentulous arch immediately following abutment connection, termed conversion prosthesis, is described in detail. Advantages of the restoration include the following: it provides a fixed prosthesis immediately following stage 2 surgery with improved function, stability, and distribution of load; it protects the sutured mucosa; it serves as a prototype for the final prosthesis; it can be used as a verification jig; it preserves the original vertical dimension of occlusion; it aids in obtaining and transferring the interocclusal record; it assists long-term patient maintenance; and it reduces treatment visits. The advantages of its use clearly outweigh the disadvantages.
