METHOD OF PREVENTION OF ALVEOLAR BONE ATROPHY USING LITAR ALGINATE MATERIAL Russian patent published in 2023 - IPC A61C7/00 A61K31/136 A61P1/02 A61N5/67 

FIELD: medicine; surgical dentistry.

SUBSTANCE: invention is intended for use in the prevention of alveolar bone atrophy immediately after tooth extraction and in preparing the tissues of the prosthetic bed for prosthetics. Using elevators, burs and drills, atraumatic tooth extraction is performed. The socket of the extracted tooth is curetted and the socket is expected to be completely filled with blood. The resulting defect is filled with “LitAr” alginate material with 70% silver by volume. Then the socket of the extracted tooth is sutured with non-absorbable suture material 5/0 using two z-shaped sutures. Afterwards the seams are filled with a liquid-flowing light-curing composite material, completely blocking the entrance hole to the alveolus. The patient is prescribed to take 0.5 grams of LitAr alginate material without silver orally once a day for 14 days, starting from the day of removal. The patient takes the first dose of the material half an hour before tooth extraction. Subsequently, the patient orally takes “LitAr” alginate material without silver half an hour before breakfast. In parallel, the area of the extracted tooth is exposed to pulsed radiation with a wavelength of 905 nm from a semiconductor laser in the infrared spectral range of a high power level of 30 W, exposure for 2.5 minutes to two extraoral areas on the skin of the face — in the projection of the medial approximal wall of the extracted tooth and in the projection of the distal approximal wall of the extracted tooth. Course contains 6–8 daily procedures. First irradiation is performed on the day of tooth extraction.

EFFECT: due to the combined use of “LitAr” alginate material and pulsed radiation from a semiconductor laser, the method makes it possible to increase the effectiveness of preventing atrophy of the socket of an extracted tooth.
