Clinical application of mandibular overdenture supported by a two-implant and interforaminal bar in an edentulous atrophic mandible

doi:10.7518/hxkq.2017.04.019

Abstract

Abstract:

Implant-overdenture supported by an interforaminal bar provides stability and is effective in an edentulous atro-phic mandible. However, using this attachment requires precise planning from the restorative and surgical aspects to ensure a satisfying outcome. Consdering the feature and space requirements for bar attachment, this article establishes a clinical pro-tocol for a two-implant-retained overdenture on the mandible. In this study, a case of mandibular edentulism was considered to illustrate this protocol and provide a reference for clinical practice.

Key words: edentulous jaw, overdenture, dental implantation, mandible
