Healing of Pathologic Bone Cavities of Jaws after Augmentation

Abstract

Pathologic bone cavities of jaws are related to occurrence of bone cysts and tumors. In an extensive bone cavity after cystectomy, the post-operative haematoma may disintegrate due to inflammation at the dehiscence of the mucosa suture. The cavity originated by the cyst is connected with the oral cavity; the healing is complicated and long-continuing. We endeavor to fill this cavity with some kind of material that would not only reduce the cavity extent but also stimulate the bone re-creation.Within the framework of our research activity, we applied three shares of human lyophilized bone mash and one share of tricalcium-phosphate, which were mixed with venous blood of the respective patient until consistent material for augmentation was made. No antibiotics were added. Stage of bone healing and possible complications were regularly followed both in patients after augmentation and in a control group of patients without implanted material.Hitherto results revealed non-complicated healing in 32 patients in whom the augmentation with mixture of the above materials had been carried out (21 bone cavities after cysts and 11 benign bone tumors).
