| Outline of Final Research Achievements |
Periostin is the extracellular matrix protein that specifically localized at the periodontal ligament and the periosteum in the periodontal tissue. The expression of periostin is mediated by mechanical stress. Orthodontic force often causes the gingival recession in the occlusal hypofunctional teeth through impaired expression of extracellular matrix proteins. The aim of this research project was to clarify the influence of occlusal loss on the alveolar bone remodeling through periostin in rat maxillary occlusal hypofunctional molar moved by orthodontic wires. Data showed that occlusal hypofuctional causes impaired teeth movement with atrophic changes in alveolar bone in occlusal hypofunctional molars.
