Maxillary implant-supported overdenture with mesostructure abut-ment: A case report

Abstract

Prosthesis that require and are connected to multiple internal implant fixtures, are often difficult to fabricate. Furthermore, if the angle is not appropriate, the implant may not be retrievable. In the current case, a bar implant overdenture was planned for a full-mouth restoration of a maxillary edentulous patient. However, the prosthesis was difficult to fabricate because of the improper buccolingual angulation of the implanted internal implant fixtures. Therefore, the internal implant fixture was replaced with an external implant prosthetic system, by connecting a `convertible abutment`, which is a type of mesostructure abutment. Following this, a bar attachment was made to fabricate the implant overdenture. In this paper, we report the results of this study by supplementing the limitation of the previous implant prosthesis system, and consequently obtaining functionally satisfactory results.
