[An experimental validation of the transplantation of an orthotopic allograft together with tooth roots for the replacement of mandibular defects].

The results of transplantation of surface-demineralized, lyophilized, and formalin-treated orthotopic allotransplants, including dental roots, to 40 dogs [correction of rats] are analyzed. Clinical, x-ray, and morphologic studies have demonstrated that formalin-treated allotransplants are the optimal plastic material, providing restoration of bone intactness, preservation of dental roots, and the osteoid type of dental root join with the bone regenerate. Dental roots within surface-demineralized and lyophilized allotransplants are resolved in the course of their replacement with newly developing bone tissue.
