[Osteoplasty of the lower jaw with demineralized allotransplants]

A five-year experimental and clinical experience is presented in this paper from the studies on the osteoplastic properties of demineralized ostetoransplants (DOT) in plastic surgery of the lower jaw. The comparative evaluation of the results from the experiments shows that the DOT as well as the frozen allotransplants are substitute for newly formed osseous tissue but the regeneration process in transplantation of DOT advances faster contrary to the frozen transplants. Twenty nine patients with defects of the lower jaw underwent operations under clinical conditions. Positive results were attained in 25 of them (86.7%) and negative--in 4 (13.3%). The saturation of DOT with antiseptics (dimexid, gentamycin, etc.) allows its use also in infected defects of the lower jaw.
