[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.
