Prosthetic rehabilitation of a completely edentulous maxilla with a sectioned implant-supported screw-retained prosthesis in a multiamputee patient with microstomia: A clinical report.

Providing fixed implant-supported prostheses for edentulous patients with microstomia or limited mouth opening is challenging. The clinical treatment of a patient who was a multiple amputee with microstomia and a complete loss of lips elasticity is described. A custom half-sectioned prosthesis was fabricated to resolve numerous difficulties. A screw-retained complete implant-supported prosthesis was developed from a monolithic zirconia framework supported by 4 implants and with digital scanning and computer-aided design and computer-aided manufacturing of the prosthesis. The protocol achieved a complete screw-retained implant-supported prosthesis and offered a solution for a patient with microstomia and limited mouth opening, leading to improved quality of life.
