Clinical report -8 years follow-upPoster Presentation Background:tOral rehabilitation of edentulous distal areas with removable partial dentures (RPD) is a demanding clinical challenge. These oral rehabilitations have sometimes muco-dental support due to the absence of teeth in the posterior areas (Kennedy class I - bilateral free end and Kennedy class II -unilateral free end).Oral rehabilitation of such cases (Kennedy classes I and II) with RPD is generally associated with some problems, such as: lack of stability, minimal retention, discomfort when loading, pain on abutment teeth and frequent need of relining. There are several articles supporting that implants in such edentulous spaces are viable and should be an option under certain conditions Aim: tThe purpose of this clinical report is to present 8-years follow-up of a clinical case combining tooth, implants and removable partial denture. Material and Methods:tA 36 year old female patient, with a partially edentulous atrophic maxilla was submitted to a maxillofacial surgery to correct a skeletal class III malocclusion in June 2008 and 1 year after rehabilitated with implants and a RPD at the Faculty of Medicine, University of Coimbra, Portugal. In order to proceed with the treatment, the patient imposed some conditions: no bone grafting, sinus floor elevation or any kind of tissue graft. She also asked for a fixed rehabilitation at least in the aesthetic zone. Therefore a fixed anterior bridge on implant positions 12-22(FDI) and RPD supported by teeth 13, 23(FDI) and implants in positions 18 and 28 (FDI)tResults:tThis case with 8 years follow-up, had no problems with the implants (biological or technical), and only adverse event was the need to replace the removable partial denture after 2 years because the patient left it abroad when she went on vacations. Conclusions and clinical implications: tAfter reviewing the literature, a RPD supported by implants was the best treatment, regarding all limits imposed by the patient. tThis kind of treatment should be used in oral rehabilitation of Kennedy classes I and II in order to avoid some problems and discomfort during function.
