In modern dentistry, one of the urgent problems is the problem of bone tissue regeneration, the development of methods of optimizing the impact on reparative osteogenesis. A significant advantage of tissue regeneration is the use of membrane technology for the formation of favorable conditions necessary for the creation of a new tooth-gingival connection. Membranes are divided into two main groups: resorbed and nonresorbed. The main advantage of resorbed membranes over non-resorbed membranes is that they can biodegrade in the body. Therefore, the second operation to remove them from the body is not necessary. Resorbed membranes in turn are divided into membranes made of natural or synthetic materials. From natural materials collagen is actively used, from synthetic polypeptides-aliphatic polyesters, in particular, polyglycolide (PGK) and polylactide (PLC). From the standpoint of biology, collagen has the best structure and properties. Most of the membranes that are used in NTR have a high cost, which initiates the search for new materials for resorbed membranes. Domestic materials for resorbable membranes have good clinical efficacy. In addition, they have a lower cost than imported counterparts and are therefore more accessible to patients. Recently, NTR with the use of membranes began to develop in the direction of synthesis of materials of a new class, which would combine the advantages of non-resorbed and resorbed membranes: mechanical strength and bio-inertness with a certain period of resorption (3-6 months). It is believed that such membranes are promising materials can be biocompatible polymers, in particular, polyglycolide, polylactide, and paleoclimatical and their various combinations. Thus, in modern conditions, the use of bioresorbable membranes for directed regeneration of bone tissue in defects of the mandible is one of the most common and effective methods in dental surgery.
