Visualizing Displacement and Deformation Behavior of the Periodontium under Dental Occlusion Using a Digital Image Correlation Method

抄録

In this study, we clarified dental occlusion functions by visualizing the displacement and deformation patterns of the periodontium under dental occlusion. A digital image correlation method served as a visualization and deformation analysis method using fresh porcine periodontium specimens. Also using dried periodontium specimens, we conducted the occlusion test to characterize the differences in displacement and deformation patterns between fresh and dried specimens. Results indicated that the periodontal ligaments deform first, followed by alveolar bones. Marked differences in displacement and deformation patterns were observed between the fresh and dried periodontium specimens.
