METHOD FOR ANGIOGENESIS INITIATION IN FREE CONNECTIVE-TISSUE AUTOGRAFTS WITH "LitAr" MATERIAL Russian patent published in 2020 - IPC A61C8/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry, and is applicable in treating patients with dental implants. After preparing the patient and performing anesthesia, an incision is made along the alveolar ridge, vestibular and palatine or tongue flaps are peeled off, plugs are unscrewed and gingival formers are placed on dental implants. A free connective-tissue autograft is sampled from one of the donor areas located on the upper jaw – palate, upper jawbone or toothless section of the alveolar process. That is followed by placing the free connective-tissue autograft into a dispersed solution of "LitAr" material for 10 minutes, and then placed between gingival shapers with a greater turn of its turn to bone tissue and fixed in the recipient area by the mattress sutures, first to the vestibular flap, then to palatine or lingual, and so that lateral end of free connective-tissue autograft is brought under vestibular flap, and medial – under palatine or lingual. It is then immobilized on the alveolar crest by three crosswise sutures mesial, distally and medially, each of which passes through a free connective-tissue autograft, and after wound closure is injected with a dispersed solution of "LitAr" material into a transient fold in the area of surgical intervention, thereby initiating angiogenesis.

EFFECT: method allows reducing the lifespan of the autograft and reducing its necrotising probability.
