Successful treatment of patients with multiple complex facial bone fractures is denpendent on the precise clinical and diagnostic image, well-established systematic principles of fracture repair. The oral and maxillofacial surgeon should appreciate the postoperative complications and minimize or manage adequately. Most of complications can be treated secondarily, but we should apprecite the fatal complications which are impossible to treat.

This study was undertaken to determine whether the addition of calcium sulfate to toothash material (Toothash: plaster of paris=2: 1) would improve its stabilizing property without adversely affecting its osteoconduction. The radiographic and histologic examinations of bone response of this composite material was performed after 1-, 3-, 5-, 8-, and 12-week implantation in calvria of rats. No sign of extensive inflammatory response was detected. No movement could be observed with this composite material. Creeping substitution was observed in the surgical site. The direct union between toothash and growing bone after 12 weeks of implantation was observed in the defect margin. We could observe this composite implant material is resorbing slowly as time is over.
