Introduction The hybrid prosthesis or implant-supported, implant-retained prosthesis utilizing acrylic prosthetic gingiva is an increasingly popular restorative design for complete or partially edentulous patients. The most common clinical mode of failure is a cohesive or adhesive failure between the denture tooth and the denture base. To improve success, lithium disilicate has been proposed as an alternative material for the prosthetic tooth. To date the restorative interface between lithium disilicate and polymethylmethacrylate PMMA is untested.
