METHOD FOR BARRIER MEMBRANE MANUFACTURE FOR PREVENTION OF MUCOUS TISSUES GROWTH INTO BONE FORMATION AREA AT ORAL SURGERIES Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: patient's blood is taken to the Plasmolifting tube. The Plasmolifting tube is then centrifuged in the 850-1250 g mode for 5 minutes. The plasma obtained from the Plasmolifting tube is collected in a 2 ml syringe and heated in a thermostat at a temperature of 95°C for 5 minutes. The resulting gel is spread on a foil, so that the resulting membrane size could overlap the closed defect 1.5-2 cm outside its limits. Then the gel is covered by another layer of foil. Then the foil with the gel on the inside is laid in the tray and thermostated at a temperature of 180°C for 20 minutes. Then the obtained membrane is separated from the foil, cooled and placed into the bone formation zone.

EFFECT: method allows to obtain a membrane for directed tissue regeneration, not toxic, not carcinogenic, not antigenic, biodegradable, easily controlled with high mechanical properties, preventing mucous tissues growth into the bone formation area.
