[Osteoplasty of the lower jaw with composite grafts].

Experimentally on 32 white rats of Wistar line and on 15 outbred dogs the authors studied plastic properties and healing processes of composite transplants, employed for replacement of mandibular defects. It was found that the composite transplant consisting of an allogenic lower jaw, treated according to "os purum" type, and an autobone was more resistant to infection, showed no rejection response and possessed adequate plastic properties. This enable the authors to apply the mentioned combination clinically in 7 patients with mandibular defects from 3.5 to 15 cm. Favourable results were obtained in every patient: the anatomical shape of the jaw and its functioning was restored, a good cosmetic effect was gained.
