These parameters were compared between abutment teeth with direct and indirect retainers at baseline, and after 6 and 18 months.

Results showed that VPI and BOP decreased over time, and that VPI values were higher in abutment teeth with direct retainers (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001). There was a reduction in PD after 6 months, which was maintained up to 18 months. In general, abutment teeth with direct retainers had significantly higher values for PD, GR, and CAL (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.029). Data also indicated that the parameters for VPI, BOP, and PD improved; however, abutment teeth with direct retainers presented smaller improvements, compared with abutment teeth with indirect
