The World's Longest Functioning Implant: A Verified Case Report

Abstract

Satisfactory function, esthetics, and phonetics together with long-term stability and minimal complications are all considered as metrics that define a successful outcome. The current case report is documentation of a mandibular subperiosteal implant with a successful follow-up of 56 years. Numerous issues can be credited for the long-term successful outcome including selection of the patient, heedfulness of basic anatomic and physiologic principles, design of the implant and superstructure, surgical execution, application of sound restorative principles, conscientious hygiene, and clockwork recare. The case demonstrates intense cooperation and coordination among the surgeon, restorative dentist, and laboratory technical staff, together with long-lasting patient compliance. Execution of the treatment with a mandibular subperiosteal implant helped this patient overcome the status of a dental cripple. The highlight of the case is that it is the longest success ever documented in the history of any type of implant treatment.
