[Morphology of the mandibular condyle in osteopetrotic (op/op) mouse].

Osteopetrosis is an inherited metabolic disease which produces an excessive accumulation of bone caused by deficiency of osteoclasts. It is characterized by systemic bone sclerosis, cranial deformation and failure of tooth eruption due to defective bone resorption. In this study, morphological change of the mandible was observed in growing osteopetrotic (op/op) mutant mice. Deformation of the condylar process, non-ossification of the condyle head and underdevelopment of the lateral pterygoid muscle were observed in the mutant mice. Although these phenomena were brought about by failure of the bone remodeling, it was simultaneously suggested that the ossification of the condyle head concerned with the mastication.

Comparison of absorbable self-reinforced poly-L-lactide screws and metallic screws in the fixation of mandibular condyle osteotomies: an experimental study in sheep.

Nine osteotomies of the neck of the mandibular condylar process in sheep were fixed with self-reinforced poly-L-lactide screws and nine with metallic screws; two osteotomies were left unfixed. Radiographic examination was carried out at 3 weeks. The animals were killed at 6, 12, and 24 weeks. Malalignment was detected at 3 and 12 weeks in both unfixed condyles. The consolidation of the fixed osteotomies seemed to be faster in the polylactide group than in the metallic group. There were no complications in the healing of the fixed osteotomies.
