Research progress in the mandibular molar implant restoration with frontal resorption The most significant variable related to third molar impaction is inadequate space for tooth eruption. 种植修复下颌磨牙区牙槽骨吸收的研究与进展大多数阻生的下颌第三磨牙磨牙后间隙牙冠近远中径比值小于1。
Conclusion Flat bite plate can cause root resorption of mandibular permanent incisors, but the root resorption is slight. 结论平面导板会造成下前牙牙根的吸收,但根吸收程度轻微。
Mandibular desease is one of the commen desease in oral maxillofacial surgery. Mandibular function disorders caused by abnormal bone resorption and bone defection compose the main pathological changes. 颌骨疾病是口腔颌面外科常见病之一,其主要病理变化是各种原因引起的骨吸收或骨缺损而造成颌骨功能障碍。
Animal experiments with ovariectomized ( OVX) rats also demonstrated that estrogen deficiency may result in low mineral density of mandible, thin cortex of mandibular body, and resorption of alveolar bone. 动物实验研究发现大鼠去势(OVX,ovariectomy)诱导的雌激素缺乏可引起下颌骨密度降低、下颌骨骨皮质变薄及牙槽骨吸收。
