Comparative Characteristics of the Chemical Structure of Barrier Membranes: A Review

Currently, due to the high frequency of dental implantation and targeted bone regeneration of periodontal tissues worldwide, it is particularly important to improve methods for restoring the original volume of alveolar bone tissue. To achieve this goal, various surgical procedures are used, which result in the formation of bone volume necessary to create a complete bone bed for both the tooth and the implant. The review aims to analyze the literature data on the use of barrier membranes in implantology and targeted periodontal tissue regeneration with special emphasis on their chemical structure, as well as to identify their main disadvantages and advantages. As a result of the search, 245 publications were extracted from the PubMed/MEDLINE, Google Scholar and eLibrary databases.EN, after the selection procedure, 30 articles were included in the review. The main task of targeted periodontal tissue regeneration in recent years has been to create a unique type of barrier materials that would be maximally biocompatible and combine the properties of non-absorbable (non-absorbable) and resorbable (absorbable) membranes. Alternatively, polylactide and polyglycolide can act as promising materials for this type of membrane.
