BACKGROUND
Researchers have generally focused on tissue reactions occurring within the periodontal ligament and bone to find possible explanation for various clinical phenomena, with less attention being paid to the inherent bone density. Recently, regional differences in jaw anatomy and bone structure including bone density have become important issue to explain some of the variation in clinical practice with respect to tooth movement, implant success rate, anchorage loss etc.
MATERIALS AND METHODS
The intent of this review is to discuss various methods and classification proposed to determine bone density in particular area and its importance in field of orthodontia. Various clinical studies and research done in relation to bone density were searched using PubMed.
RESULTS AND CONCLUSION
This review endeavours to compile the research of bone density in maxilla and mandible. Many clinical studies have demonstrated relation between bone density and various clinical phenomena in dentistry. Knowledge of bone density in particular area of oral cavity may help the clinician to plan proper site for implant placement and various anchorage augmentation techniques in order to increase success rate of the treatment.
背景
研究人员通常专注于牙周韧带和骨内发生的组织反应，以寻找各种临床现象的可能解释，而对固有骨密度的关注较少。最近，颌骨解剖结构和骨结构（包括骨密度）的区域差异已成为解释临床实践中牙齿移动、种植成功率、支抗丧失等方面某些差异的重要问题。
材料与方法
本综述的目的是讨论为确定特定区域骨密度而提出的各种方法和分类，以及其在正畸领域的重要性。使用PubMed搜索了与骨密度相关的各种临床研究。
结果与结论
本综述致力于汇编上颌骨和下颌骨骨密度的研究。许多临床研究已经证明了骨密度与牙科各种临床现象之间的关系。了解口腔特定区域的骨密度可能有助于临床医生规划种植体植入的合适部位以及各种支抗增强技术，以提高治疗成功率。
