The use of a gel based on a liposomal antioxidant-phospholipid complex in combination with low-intensity laser radiation in the complex treatment of patients with peri-implantitis

Relevance. Peri-implantitis is one of the common problems in modern dentistry. Methods of prevention and treatment of patients with implantitis do not provide high efficiency. Objective: to increase the efficiency of treatment of patients with peri-implantitis by developing a method of using a gel based on a liposomal antioxidant-phospholipid complex in combination with low-intensity laser radiation. Materials and methods. A retrospective and prospective study of 90 patients with peri-implantitis and 12 patients without inflammatory phenomena aged 25 to 55 years was conducted with control after treatment and after 1, 3, 6, 12 months. The hygiene index OHI-S, PI, PMA, bleeding indices and the Schiler – Pisarev test were assessed. Laser Doppler flowmetry (LDF), determination of implant stability (IS), laser fluorescence diagnostics (LFD) of the hygiene level were performed; radiographic examination. In group IA – application of a gel based on a liposomal antioxidant-phospholipid complex, in IB – exposure to low-intensity laser radiation in the infrared range with an output power of 25 mW, in IB – application of gel (similar to IA) in combination with exposure to low-intensity laser radiation (similar to IB); group II (control) without inflammation around the implant. Results. After 12 months, the greatest decrease in OHI-S, on average, by 80.8% (p
