Abstract
Statement of problem
A consensus on the clinical performance of implant-supported removable partial dentures
(ISRPDs) is lacking.
Purpose
The purpose of this systematic review and meta-analysis was to evaluate the clinical
performance of ISRPDs in terms of the implant survival rates, marginal bone loss,
and patient-reported outcome measures (PROMs).
Material and methods
Four electronic databases (MEDLINE/PubMed, EMBASE, Web of Science, and Cochrane Library)
were independently searched by 2 reviewers for articles published up to December 2020.
A single-arm meta-analysis was performed to evaluate the implant survival rates and
marginal bone loss by using the R program. The Cochrane collaboration tool was used
to evaluate the risk of bias of randomized controlled trials (RCTs), and the Newcastle-Ottawa
scale for non-RCT studies.
Results
Sixteen studies were included, with a total of 334 participants and a mean age of
58 years. The participants received a total of 581 dental implants, 475 conventional
and 106 mini-implants. All included studies reported implant survival rate above 90%
(range: 92% to 100%). Meta-analysis indicated a high proportion of implant survival
rates of 3% (95% confidence interval [CI]: 2% to 5%) and a low mean raw score of marginal
bone loss 0.98 mm (CI: 0.61 to 1.36 mm). Compared with conventional RPDs, improved
patient quality of life and satisfaction were reported by studies that evaluated ISRPDs.
RCT studies exhibited a low risk of bias for most domains, while most non-RCT studies
were classified as good quality.
Conclusions
ISRPDs exhibited high implant survival rates and acceptable bone loss with improvement
in the quality of life and satisfaction of patients when compared with conventional
RPDs. Therefore, they can be considered suitable for the rehabilitation of partially
edentulous patients.
