The treatment of edentulous arches with fullarch fixed dental prosthetics is the oldest form of restorations placed on root form endosseous implants as presented by Branemark et al. in 1977. Many different techniques and philosophies of fixed full-arch restorations have been developed and described in the last 55 years which include but are not limited to different type of restorative materials, implant numbers and angulations, management of the restorative space, healing protocols, and analog or digital workflows. Even though some these variations of full arch therapy may be clinically simpler to perform than others, the final prostheses usually require final insertion with prosthetic screws than make the prosthetic material easier to fracture and create the necessity to utilize materials to seal screw access holes. These issues increase the maintenance times and the potential for prosthetic complications throughout the life of the prostheses. Imagine being able to design and build an FP-3 full-arch (fixed-detachable hybrid) prosthesis, utilizing the current techniques used to make a simple denture or overdenture. Imagine being able to deliver these prostheses with a single snap, and perform maintenance and repair appointments without having to drill screw access covers, removing screws, choosing new screws, and torquing the prosthesis, and resealing it after the required procedure.

Interim dentures were fabricated prior to the extractions. All remaining teeth were removed, alveoloplasty performed, and implants placed at the same appointment. The interim dentures were inserted immediately after surgery with a tissue conditioning reline material. The patient was allowed to heal for 4 months, then the implants were successfully tested for osseointegration. LOCATOR abutments were selected and torqued as recommended by the manufacturer prior to beginning the definitive prosthetic treatment. Maxillary and mandibular implant-retained overdentures were fabricated using traditional indirect techniques. Both prostheses included metal frameworks for strength and long-term survival, and the LOCATOR housing were pickedup chairside at the time of delivery. Our patient reported to be very happy and pleased with his new smile at the time of delivery. But after several adjustment appointments he reported constant problems with his maxillary overdenture causing gagging and nausea after 1 or 2 hours of wearing his prosthesis. For over 1 year he only wore his denture a few hours per day and at mealtimes and he felt his quality of life had not improved since the time of extractions.
