[The state of microhemodynamics and oxygenation in the mucous membrane of the alveolar ridge after gingival contouring during dental implantation].

The results of a comparative assessment of the state of hemomicrocirculation and oxygen metabolism in the mucous membrane of the alveolar crest after contour plastics of the gums during dental implantation using a connective tissue graft from the upper jaw, a connective tissue transplant from the palate and the collagen matrix collagen matrix are presented. During contouring with the use of connective tissue graft (CTG) from the upper jaw and collagen matrix in the mucous membrane of the alveolar mandible, the level of tissue blood flow decreases, which characterizes the development of ischemia, which is stopped after 3 weeks, when using a connective tissue graft (CTG) from the palatine, the level of tissue blood flow rises, which indicates the development of hyperemia, which is stopped for more than 3 weeks. According to oximetry data after contouring with the use of various surgical techniques, the level of oxygenation and oxygen metabolism is reduced by 8-38%, which characterizes the development of hypoxia, which is stopped after 3 weeks when using CTG from the hillock of the upper jaw and collagen matrix for more than 3 weeks when applying CTG from the palatine.
