[Clinical use of BAS-O, a bioactive glass ceramic, for filling cystic cavities in stomatology].

The bioactive glass-ceramic material BAS-0 and results of clinical testing of this material in stomatology are described. The granules of bioactive glass-ceramic BAS-0 were chosen for implantation into cyst cavities in jaw-bones. Radiological evaluations were carried out after 3, 6 and 12 months. Altogether 37 radiographs of 23 patients were evaluated. The symptoms of ossification were proved in 28 cases (75.7%), 5 radiographs (13.5%) were without visible apposition of the bone and in 4 cases the loss of the BAS-0 granules from operation wound was observed (10.8%). The authors proved very good healing properties and tolerance of BAS-0 material, no significant changes in biochemical and haematology examinations were observed.
