Abstract

Implant-assisted removable partial denture (Implant-assisted RPD, IARPD), posterior edentulous extension areas of which obtains additional support and retention from implants, is attracting increasing interest. This case report presents a successful treatment on a partially edentulous patient with a severely canted occlusal plane resulted from a long-term use of posterior extended RPD. The full mouth was rehabilitated through a fixed prosthesis on maxilla and IARPD with zirconia occlusal surface on mandible, which allowed to achieve an esthetic occlusal plane with long-term stability and, ultimately, functionally satisfying outcome.
