Survival rate and clinical evaluation of the implants in implant assisted removable partialdentures: surveyed crown and overdenture

ABSTRACT

PURPOSE@#. The purpose of this study was to investigate survival rates of the implants used in implant assisted removable partial dentures (IARPDs). @*MATERIALS AND METHODS@#. The study was conducted on 21 patients who were treated with IARPDs. The mean follow-up period for IARPD patients ranged from 12 to 185 months (mean 47.9 months). A total of 58 implants were used for IARPDs in two different modalities: 41 for surveyed crowns and 17 for overdentures. The survival of implants was determined by clinical and radiographic evaluations considering relevant factors: location, RPD classification, opposing dentition, splinting, and implant diameter. @*RESULTS@#The survival rate of total 58 implants was 93.1%: 95.1% for implants supporting surveyed crowns and 88.2% for implants used in overdentures. Considering only the implants supporting surveyed crown, regular diameter implants showed a higher survival rate than narrow or wide diameter implants. @*CONCLUSION@#The survival rate of the implants used in IARPDs was 93.1% (surveyed crown: 95.1%, overdenture: 88.2%).
