Prosthetic maintenance of different mandibular implant overdentures: A systematic review.

Statement Of Problem: Different factors can affect prosthetic maintenance requirements for mandibular implant overdentures (IODs). However, the literature shows a high level of disagreement concerning the effect of each factor on maintenance needs.

Purpose: The purpose of this systematic review was to address the focus question: "In the clinical studies published since 2004 of adult patients with totally edentulous mandibles treated by IODs with a variable number of implants and different designs, what were the maintenance types, frequencies, and complications?"

Material And Methods: A search of MEDLINE and PubMed databases was performed targeting papers in English on prosthetic maintenance of mandibular IODs published between 2004 and June 2015, aiming at recognizing the needs for adjustment, repair, and renewal.

An implant impression technique using a plaster splinting index combined with a silicone impression.

This article describes a technique for making implant impressions designed to reduce framework misfit. The 2-stage impression technique combines the use of plaster and a silicone impression material. The method can be used for either completely or partially edentulous patients.
