An implant-supported overdenture may be practically advantageous over conventional complete denture and removable partial denture. They reduce bone resorption and has greater prosthesis stability, improved maintenance and better esthetics. Implant supported overdenture may reduce the amount of soft-tissue coverage and extension of the prosthesis. Hygiene condition and home maintenance procedures are improved with the overdenture compared with fixed prosthesis. Implant supported overdenture limits lateral movements and consequently minimize soft-tissue trauma. Greater stability of implant-supported overdenture drives from mechanical attachment of the implant support system retaining the restoration. In severe resorption cases, this is a better alternative than the fixed restoration.
