Mandibular implant-retained overdentures with 2 different prosthetic designs: a retrospective pilot study on maintenance interventions.

Int J Prosthodont 2006 Nov-Dec;19(6):557-9

Faculty of Medicine and Surgery, School of Dentistry, University of Torino, Italy.

This retrospective study aimed to investigate whether a mandibular implant-retained overdenture designed to counteract the rotation of the denture might influence the clinical outcome, as evaluated through the prosthetic maintenance interventions. The amount of repairs and relines of the mandibular and maxillary dentures required in an experimental group (6 patients wearing an implant-retained overdenture with a metal frame counteracting the rotation) and a control group (6 patients wearing an implant-retained overdenture allowing the rotation) was compared. Both mandibular and maxillary dentures needed few repairs or relines. The 2 types of dentures showed a similar number of maintenance interventions.
