XENOGENIC COLLAGEN GEL AND LASER LIGHT IN PROPHYLAXIS AND MANAGEMENT OF PERIIMPLANTITIS: A PILOT STUDY

Abstract

Subject. The periimplantitis management and prophylaxis technique using xenogenic collagen gel and laser technique, analysis of their results. Aim. To evaluate the effect of periimplantitis management and prophylaxis with xenogenic collagen gel and laser technique. Methodology. The study was conducted on the basis of Sechenov University from 2020 to 2022. The study included ten patients with diagnosed peri-implantitis (age range 28–45 years, median is 35 years). All patients underwent professional hygiene followed by division into 2 groups by random sampling: patients of group 1 were injected with xenogenic collagen gel in the area of the peri-implant pocket and in the soft tissues around the dental implant in the area of alveolar bone resorption, patients of group 2 were subjected to laser bactericidal treatment of peri-implant pockets. The results were evaluated by the depth of probing of the peri-implant pocket and the clinical symptoms of the disease, the presence of adverse outcomes after the application of the techniques. Results. During 12 months of observation, a decrease in the depth of the peri-implant pocket during probing was noted by an average of 3 mm from the initial depth in both groups (p < 0.05), an increase in the volume of soft tissues around the implants, mainly when xenogenic gel was used (p < 0.05). Conclusions. Xenogenic collagen gel and laser microbiocidal treatment of peri-implant pockets may be an alternative treatment for peri-implantitis after full-fledged randomized clinical multicenter trials.
