Sažetak

This article reviews different types of membranes for guided tissue regeneration. They are used to cover defects and stimulate regeneration of osseous defects in periodontal pockets. A membrane should be biocompatible, enable cell exclusion separating the gingival flap from the fibrine clot and guard space for the new alveolar bone and the periodontal ligament.
Membrane can be non-resorbable and resorbable. When non resorbable membranes are used, another surgical procedure for their extraction is needed. They are therefore used less frequently today. The majority of these membranes are made of polytetrafluoretylene, e.g. Gore-Tex membrane.
Resorbable membranes shorten the treatment since there is no need for their removal. They can be made from natural materials like collagen, laminar bone, dura mater or connective tissue transplants and from synthetic resorbable materials, most frequently derivatives of organic aliphatic thermoplastic polymers. Polyglycolic and polylactic acids are mostly used. This group includes the Atrisorb membrane that has to be prepared intraoperatively. The use of polyurethane membranes is presently being tested.
So far the perfect membrane has not been discovered. Collagen membranes are most popular due to their optimal biocompatibility, although their rate of resorption is difficult to predict.
