A REVIEW ARTICLE: USE OF NEW METHODS AND MATERIALS TO INCREASE SOFT TISSUES OF GUM

INTRODUCTION: Gum plastic surgery is an integral part of surgical dentistry and modern dental implantology. The increasing of the gum soft tissue volume allows to eliminate the manifestations of some pathologies of the dental system (gum recession, exposure of the roots of teeth, etc.) and is carried out both in preparation for implantation and after the installation of dental implants, which is confirmed by a number of scientific studies. METHODS: In the review it is analyzed the basic surgical techniques and materials used for the increasing of keratinized gum, such as dermal and collagen matrix. The analysis of the literature highlights the main advantages and disadvantages of these methods and materials, the most significant and promising areas for further clinical research. CONCLUSION: analysis of the literature on the methods and materials used for increasing of the volume of gum showed that the use of collagen matrices is promising due to the imperfection of the classical technique using the "gold standard" - free connective tissue flaps - and good results of the studies obtained for the matrices in terms of the effectiveness and safety of the material.
