Survival rate and clinical evaluation of the implants in implant assisted removable partial dentures: 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%). [ J Adv

New Rehabilitation Concept for Maxillary Edentulism: A Clinical Retrospective Study of Implant Crown Retained Removable Partial Dentures

“…A previous study showed when the opposing dentitions were RPD or CD, there were no implant failures, resulting in a 100% survival rate [ 47 ]. In the present study, all opposing dentitions were natural teeth, fixed implant prostheses, or IOD, and overall implant survival rate was 84.1%.…”

Clinical Performance of Implant Crown Retained Removable Partial Dentures for Mandibular Edentulism—A Retrospective Study

“…Usually survival rates for fixed implants in edentulous patients are reported in the range of 92.1% [ 22 ] to 95.6% [ 23 ]. Kang et al showed that the survival rate of implants in IC-RPDs for partially edentulous mandible was 93.1% [ 24 ]. The 5-year prospective randomized study by Gotfredsen and Holm showed a success rate of 100% in IODs [ 25 ].…”

In Vitro Assessment of the Effect of Implant Position on Biomechanical Behaviors of Implant-Supported Removable Partial Dentures in Kennedy Class II Condition

“…IARPD or ISRPD can overcome the shortcomings of distal extension RPDs less invasively and more economically [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. An ISRPD in which implants provide support only, not retention, can be a simple method [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ] and can avoid subsequent complications [ 22 , 23 , 24 ].…”

“…However, some patients are note able to have a sufficient number of implants because of conditions such as residual bone volume and quality. To overcome these problems, the use of implants as source of support and retention for distal extension RPD was introduced and has since been evaluated [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. This type of prosthesis is generally called “implant-assisted RPD (IARPD)” [ 5 , 6 , 8 ].…”

“…Support by fewer implants can prevent movement towards the tissues and these adverse phenomena. Implant-supported RPDs (ISRPDs) have been defined as RPDs with implants that provide support only [ 8 ]. ISRPDs can work with healing abutments or caps onto implants, without any specific attachments [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ].…”
