Title Dental Implant-Retained Partial Removable Dental Prostheses (PRDP) Result in Greater Patient Satisfaction than Conventional PRDPs
Clinical Question Do dental implants and retentive abutments increase patient satisfaction with partial RDPs, as compared to conventional partial RDPs?
Clinical Bottom Line Implant-retained partial removable dental prostheses have greater patient satisfaction than conventional partial removable dental prostheses.

#1) 22882547de Freitas/201249 participants with 98 implants in 5 included studies Systematic review of non-randomized trials
Key resultsBased on the limited availability of scientific evidence, the four retrospective studies all yielded an increase in patient satisfaction with the implant-retained prosthesis. However, the grading scales for satisfaction were different between studies, making direct comparison impossible.

The Evidence
This systematic review supports the viewpoint that an implant-retained partial removable dental prosthesis is more satisfactory to a patient compared to a conventional partial removable dental prosthesis. However, more studies with a high level of evidence and similar metrics are needed. Perspective: There were not many studies in this systematic review nor did the pooled data contain a large number of subjects. Of those studies included, a majority were retrospective. Retrospective trials are based on observations taken in an uncontrolled manner. This results in outcomes that could be misunderstood. Also, in some of the included studies, the patients had both maxillary and mandibular rehabilitations, presenting another challenge in measuring outcomes because the bone differs so greatly in between arches. The studies should have standardized metrics to measure and quantify patient satisfaction of the implant-retained removable dental prosthesis compared to the conventional removable dental prosthesis.
Applicability Given the results of this systematic review, an implanted-retained partial removable dental prosthesis would be more satisfactory than a conventional removable dental prosthesis. This would yield a happier patient and a more predictable prosthesis. However, it is important to consider the additional costs associated with placing implants. The cost will be much higher than a conventional removable dental prosthesis resulting in a lower affordability. Also, not every patient will be a good candidate to have implants placed for the support of retentive anchors, further limiting the potential patient base for implant-retained partial removable dental prosthesis. Additionally, any adjustments needed involving the retentive abutments might have to be completed by a prosthodontist, which would require referral.
