[Clinical study of periocline on peri-implantitis treatment].

Objective: To evaluate the clinical outcome and the effects of treating peri-implantitis with periocline.

Methods: Thirty-two sites in 32 implants with peri-implantitis were treated with periocline. The parameters including plaque index, probing depth (PD) of pocket, sulcular bleeding index (SBI) were measured at baseline, 1, 3, 6 and 12 weeks after treatment and followed up for 6 months.

Results: Statistically significant decrease (P < 0.05) in SBI, and PD occurred at all time intervals compared to baseline. The treatment could last for at lest four weeks in peri-implantitis cases without fistula.

Conclusions: Periocline could be safely and effectively used in treating peri-implantitis in cases without peri-implant fistula. Peri-implantitis with fistula should be treated in combination with surgical methods, and periocline can also be used to control inflammation before surgery.
