FIELD: medicine.
SUBSTANCE: claimed invention relates to medicine, in particular to surgical dentistry, and is intended for use in dental implantology with insufficiency of bone tissue of the alveolar process in the distal upper jaw. Blood is sampled from the patient’s ulnar vein; then, an autogenous fibrin clot is obtained from the obtained blood by centrifugation. Further, the mucous membrane is incised along the alveolar crest with exfoliation of the mucoperiosteal flap with release of the bone bed surface. Further, the bone bed is drilled to form a hole for the implant installation. Then osteotome is used to break maxillary sinus floor wall. After mobilization of the bone fragment, its further elevation is performed by pushing the autogenous fibrin clot into the maxillary sinus cavity through the hole of the implantation bed. Further, an implant is introduced into the formed bone bed, after which the mucoperiosteal flap is placed in place and the wound is closed. An autogenous fibrin membrane is formed from the centrifuged autogenous fibrin clot by compressing the fibrin clot. Then the obtained fibrin clot is impregnated with liquid fibrinogen, having previously performed linear perforations of the surface of the autogenous fibrin membrane. Thereafter, the autogenous fibrin membrane is cone-shaped. Further, the autogenous fibrin membrane is cut into equal cylindrical parts, wherein lifting of mobilized bone fragment is carried out by uniform filling of maxillary sinus cavity with autogenous fibrin membranes cut into equal cylindrical parts, and as a final manipulation, the flaps are closed by common sutures with absorbable suture material.
EFFECT: method, by raising the bone fragment by uniform distribution of the autogenous fibrin material, allows reducing risk of maxillary sinus mucosa perforation, postoperative complications, stimulating bone tissue regeneration, restoring lost volume.
