Background The aim of this randomized clinical trial was to evaluate the efficacy of Apically Positioned Flap with Fibre Retention Osseous Resective Surgery (FibReORS) or Osseous Resective Surgery (ORS) to treat periodontal pockets associated with infrabony defect ≤3 mm at posterior natural teeth. Material and methods Thirty patients with chronic periodontitis showing persistent periodontal pockets after cause‐related therapy were enrolled; 15 patients were randomly assigned to FibReORS (test group) and 15 to ORS (control group). Measurements were performed by a blind and calibrated examiner. Outcome measures included intra‐operative and post‐operative morbidity and root sensitivity, 1‐year probing depth (PD), gingival recession (Rec) and radiographic bone changes. Results No differences in clinical and bone defect parameters were observed at baseline. Marginal bone resection was reduced by 0.9–1.6 mm in the FibReORS group. ORS was associated with patient perception of greater surgical hardship ( p = 0.0264), higher 1‐week pain experience ( p = 0.0001) and greater dental hypersensitivity ( p = 0.0002). After 1 year, shallow, maintainable PD with no difference between the two procedures ( p = 0.3707) was obtained. FibReORS was associated with less final Rec ( p < 0.0001) and less radiographic bone loss ( p < 0.0001) than ORS. Dental hypersensitivity remained significantly higher in the ORS group ( p = 0.0024). Conclusion FibReORS was similarly effective as ORS for PD reduction with less final Rec and patient morbidity.
