Application of barrier membranes made of acellular collagen matrix for alveolar ridge reconstruction with guided tissue regeneration method

The guided tissue regeneration (GTR) is one of the basic ways for alveolar ridge reconstruction in the implantology and periodontology. It has been using for more than 30 years and allows to get stable and predictable outcomes. However, quality and volume obtained tissues depends on a wide range the local, systemic and technological features which have to be taken into account. Only this approach let us achieve predictable and stable outcomes of the therapy. In the article two clinical cases of GTR are depicted in two different applications of the dermal matrix Collost usage as a collagen barrier membrane.
