FEATURES OF PREVENTIVE MEASURES FOR DENTAL PROSTHETICS SUPPORTED BY DENTAL IMPLANTS

Abstract

Main goal increasing the effectiveness of orthopedic treatment and prolonging the period of use of fixed dental prostheses based on dental implants through the use of supportive therapy of peri-implant tissues. Material and methods. The research was carried out at the Department of Stomatology of the Institute of Postgraduate Education of the Bogomolets National Medical University and at the Department of Dentistry of the Shupyk National Healthcare University of Ukraine. We observed 55 people aged from 30 to 59 years, of which 22 men and 33 women with included defects of the lateral areas of the tooth rows, who were made artificial crowns supported by dental implants. 27 persons (group I) underwent dental implantation after traditional sanitation of the oral cavity and professional oral hygiene. Individuals of the II group, in the number of 28, were additionally prescribed a treatmentprophylactic complex, which included professional oral hygiene, photodynamic therapy of peri-implant tissues, which was applied before the application and during the use of orthopedic structures based on dental implants, and prescribed quertin and quercitin. The control group (III group) included 12 people of the same age group with intact dentitions and physiological forms of bite, who had intact dentitions without clinically diagnosed periodontal tissue diseases and teeth affected by the carious process. Results. Prosthetics of a group of patients with the appointment of sessions of supportive photodynamic therapy, which is applied before application and during the use of orthopedic structures with support on dental implants, in comparison with the results of prosthetics without any supportive therapy of peri-implant tissues, indicate an improvement in the hygienic state of the oral cavity, a decrease in inflammatory dystrophic changes of peri-implant tissues, the period of use of orthopedic structures, which allows to avoid recession of the gingival margin in the peri-implant area, reduce the risks of bone tissue dehiscence and, accordingly, prolong the period of use of non-removable orthopedic structures. Conclusions. The use of dental prostheses based on dental implants, due to the retention properties of the design, contributes to the deterioration of oral hygiene and, accordingly, the formation of a biofilm with the phenomenon of "Quorum Sensing", which requires the use of professional oral hygiene and photodynamic maintenance therapy. Prescribing sessions of photodynamic maintenance therapy, before applying and during the period of use of orthopedic structures, helps to improve the hygienic condition of the oral cavity, reduce inflammatory and dystrophic changes of periapical tissues during the period of use of orthopedic structures, which makes it possible to extend the period of use of orthopedic structures.
