| 内容記述 | Lateral deviation of the mandible occuring during growth appears to cause asymmetrical growth of the dentofacial complex containing the mandible. In this study, a mandibular lateral shift was induced on a growing rat with a posterior inclined plane, and the influence to the growth of the mandible was discussed. As experimental animals, Wistar albino rats were used. For the experimental group, the posterior incliend plane made of silver alloy was worn to the maxilla, to shift the mandible laterally. The experimental periods were 3, 7, 21, and 42 days. After these periods, the animals were sacrificed and morphologically and histologically examined. Results were as follows. 1. With the dental change, the mandibular molars in the side with interference were inclined lingually. The degree increased gradually with time. The mandibular midline shifted to the uninterfered side and the incisal edge of the maxillary incisors were worn, inclining to the uninterfered upper side. 2. In the initial stage of this experiment, the mandibular shape showed transformation. In the 7, 21, and 42 days groups, the width of the condyle in the side with interference decreased, when compared with the uninterfered side. Ramus height at 21 and 42 days decreased and the gonial processes became smaller than in the control group. However, in the uninterfered side they showed few morphological changes. 3. In the histological examinations, the thickness of the condylar cartilage layer in the side with interference increased at 3 and 7 days, however, there were no differences at 21 and 42 days. In the uninterfered side, the thickness of the condylar cartilage layer decreased and the shape of the condyle was flattened in the lateral region. In conclusion: in the early period of growth, it is suggested that condylar cartilage changes with the mandibular lateral shift, then both this change and muscular functional changes inhibit the vertical growth of the ramus in the side with interference and causes asymmetrical changes to the mandible. | |||||
