Abstract
Introduction: Peri-implantitis represents a major issue in implant dentistry, often requiring surgical intervention, as non-surgical treatment does not always achieve clinical endpoints. Implantoplasty is a surgical technique aimed at smoothing the contaminated implant surface to reduce bacterial biofilm adhesion.
Methods: Five patients (eight implants) were included in this retrospective case series. Clinical and radiographical parameters—including probing depth (PD), bleeding on probing (BoP), mucosal recession (REC), visible plaque index (VPI), and marginal bone loss (MBL) were collected at baseline and after a minimum of 12 months of follow-up from medical records. Statistical analysis was conducted according to the results of the normality test.
Results: Improvement was observed in all clinical parameters except REC: mean PD (5.3 ± 1.8 mm to 2.8 ± 0.7 mm, p = 0.011), BoP (87.5% to 6.2%, p = 0.014), VPI (58.3% to 29.2%, p = 0.042), and REC (0.7 ± 1.3 mm to 2.3 ± 1.4 mm, p = 0.011), while variation in MBL was not statistically significant. No implant failure or loss was recorded during follow-up.
Conclusion: Implantoplasty provided stable, long-term clinical and radiographic outcomes in the treatment of peri-implantitis.
