peri-implant marginal bone loss in cement- and screw-retained prostheses.
Material and Methods: Electronic database and manual searches were undertaken
to identify trials, prospective or retrospective studies reporting on radiographic
marginal bone loss around dental implants restored with cement- and/or screwretained
prostheses. Two reviewers independently conducted the article selection
and data extraction. Random-effects models were used to obtain estimates of
peri-implant marginal bone loss [mean, 95% confidence intervals (CI)].
Results: Of the 1217 identified studies, nine finally met the inclusion criteria. Only
two studies included both cement- and screw-retained prostheses, three assessed
only screw-retained prostheses, and four evaluated only cement-retained prostheses.
Pooled mean marginal bone loss was 0.53 mm (CI 95%, 0.31–0.76 mm) for cementretained
prostheses and 0.89 mm (CI 95%, 0.45–1.33 mm) for screw-retained
prostheses.
Conclusion: There is no evidence to support differences in the marginal bone loss
through indirect comparison between cement and screw-retained restorations.
