摘要: 目的 应用牙CT检测手段,对颧牙槽峭的宽度进行分析,为临床种植钉植入提供参考。方法 对21例正畸患者的41颗上颌第一恒磨牙根方的颧牙槽嵴宽度进行测量和分析,应用SPSS16.0软件包进行统计学分析,比较颧牙槽嵴厚度在性别、左右侧、近远中颊根方及牙根长度之间是否存在显著差异。结果 在第一恒磨牙近远中颊根的根方的颧牙槽嵴是一个解剖结构变异较大的骨组织结构,厚度存在较大的个体差异,在性别和左右侧不存在显著差异。随着测量部位向颅方移动,颧牙槽嵴宽度逐渐降低。第一恒磨牙的颊侧根长度存在性别差异,男性牙根较女性长。结论 颧牙槽嵴的宽度存在较大个体差异,在该区域植入正畸种植钉,需进行宽度的测量分析后进行。

Abstract: PURPOSE : Using dental 3D-CT to analyse the infrazygomatic crest width. METHODS : In 21 orthodontic patients, infrazygomatic crest width was measured and analyzed in 41 CT images of the maxillary first molar root. SPSS16.0 software package was used for statistical analysis. The infrazygomatic crest width and first molar root length were compared in gender, left and right side, in mesial and distal buccal root side, to determine of there was a significant difference. RESULTS : The anatomical structure of infrazygomatic crest was bone structure with great variation. Individual difference existed in the thickness of infrazygomatic crest. There was no significant difference between sex and right and left side. As the measurement moved cranially, infrazygomatic crest width decreased gradually. Significant difference existed in first molar root length between male and female, the root length was significantly longer in male than in female. CONCLUSIONS : Individual differences existed in the width of infrazygomatic crest. Measurement and analysis of the infrazygomatic crest width is needed in this region before inserting orthodontic miniscrews.
