It was shown in the experimental condition on 80 female white rats using the model of the alimentary osteoporosis and periodontitis that operation of the jaw bone defect osteoplastic results in the temporary increase of the bone tissue destruction despite of the used material (hydroxiappatite, tricalciumphasphate, kollapan and collagenous membrane). The femoral bone mineral density decreasing as well as blood calcium content increasing 3 months after the operation proved this fact. Kollapan and complex using of hydroxiappatite with tricalciumphasphate were the most effective in their influences on the mineral balance.
