[The healing of osteotomies of the lower jaw and the adaptation of the masticatory muscles after miniplate osteosynthesis in rabbits. I. Radiologic and histological evaluation of the lower jaw].
Radiographic and histological investigations were carried out on a total of 15 rabbits after lower-jaw osteotomy and miniplate osteosynthesis. After the removal of the lower jaw (4, 8, 12 and 24 weeks) consolidation of the osteotomy surfaces without complications was observed in all animals. Radiographic examinations showed that callus formation in the operated area increased as the experiment proceeded. Histological observations made clear that only secondary bone-fracture healing resulted which must be attributed to the operation technique. These findings show that the lower jaw of the rabbit is very well suited to experimental research on miniplate osteosynthesis.
