An alternative conversion technique for fabricating an interim fixed implant-supported complete arch prosthesis.

The conversion technique enables the immediate loading of implants using an existing or a new complete denture. Acrylic resin is generally used directly intraorally when the conventional conversion technique is used. The technique described suggests picking-up the interim copings and capturing the soft tissue contour with the conversion prosthesis with a polyether impression material when 4 implants are placed with an angled implant protocol. A polyether impression was made to complete an autopolymerized reline jig reline. Acrylic resin was applied on the cast generated from this impression outside the oral cavity. This technique may minimize chair time and maximize the ability of the technician/clinician to adapt the prosthesis to the soft tissue contour.
