[The surgical treatment of jaw cysts using hydroxyapatite with an ultrahigh degree of dispersity].

Ultrahighly dispersed hydroxyapatite, a biochemically active form of hydroxyapatite, stimulates the repair osteogenesis at the early stages. Drugs with ultrahighly dispersed hydroxyapatite: 33% OSTIM-100 paste and its composition with lincomycin Lincogap, which ensures a prolonged release of the antibiotic at the site of implantation, were used for filling the bone cavity formed after cystectomy in 49 patients. In controls (n = 43) the postoperative cavity was filled with blood clot. The results of clinical, x-ray, and radiovisiographic studies indicate that use of the above preparations decreased the incidence of postoperative complications and created the optimal conditions for bone repair at the site of defects of different size. The therapeutic efficacy was the highest when the intervention was preceded by inflammatory symptoms at the site of the cyst.
