Removable prostheses may enhance marginal bone loss around dental implants: a long-term retrospective analysis.

Background: The aim of the study was to retrospectively evaluate marginal bone loss (MBL) around rough-surface dental implants, placed in a private clinic, and to construct a multivariate model based on formerly proposed prognostic variables.

Methods: Records of patients who were treated previously with dental implants were reviewed. The patients' latest annual clinical examinations and radiograms were used for data collection and the calculation of MBL.
