上下颌前牙区三维牙槽骨厚度的锥形束CT分析
|
Abstract:
摘要 目的:利用锥形束CT测量上下颌前牙区的三维牙槽骨厚度,并分析其与性别的关系。方法:共纳入华北地区174例患者的锥形束CT图像(男71例,女103例)。选定釉牙骨质界根方2 mm(L1)、5 mm(L2)、8 mm(L3)处分别测量上下颌前牙区的唇舌侧及齿间牙槽骨厚度,分析其性别差异。结果:上颌前牙区唇侧L2水平处牙槽骨最厚。上颌前牙区的腭侧、下颌前牙区的唇舌侧随着与釉牙骨质界距离的增加,牙槽骨逐渐增厚。除下颌中切牙、侧切牙L1水平外,相同水平上唇侧牙槽骨均较舌侧薄。上下颌L1水平牙槽骨缺失较普遍。上颌前牙区舌侧男性牙槽骨较女性厚,而其他位置无性别差异。结论:牙槽骨三维厚度在前牙区具有部位特异性,为口腔治疗提供重要解剖学参考
