摘要/Abstract

摘要： 目的　研究咬合重建前后颞下颌关节症状及骨性结构的影像学变化。方法　选择２０１１年１月至１２月口腔修复门诊需咬合重建的患者２０例，分别在修复前及修复后３个月进行颞下颌关节临床症状及锥形束ＣＴ影像学检查，在垂直于髁状突横轴的矢状位重建影像，测得关节前、中、后间隙。结果进行卡方检验、配对样本均数ｔ检验以及直线相关分析。结果　经过３个月的咬合重建修复，患者咀嚼肌和关节区压痛有显著改善，关节弹响未见明显好转。ＣＢＣＴ结果显示咬合重建后关节前间隙减小、后间隙增大，直线相关和回归分析显示关节后间隙的改变与咬合增高距离相关，并推导出线性回归方程。结论　测量关节后间隙对确定咬合增高的距离有一定的参考价值。

Abstract: Objective：Using the technology of CBCT and the clinical observation, to research changes of symptoms and bone structure imagings of temporomandibular joint(TMJ) after occlusal reconstruction. Methods：Choose 20 patients who need occlusal reconstruction from January to December in 2011. Check the symptoms and bone structure by CBCT of TMJ before and after 3 months occlusal reconstruction. Measure the joint space by reconstructing image perpendicular to the long axis of condyle. Statistical analysis the results to find correlation and linear regression equation. Results：After 3 months occlusal reconstruction, masticatory muscle and joint pain were significantly reduced, but joint clicking doesn’t ameliorated obviously.The results of CBCT imaging showed the anterior joint space significantly decreased and the posterior space enlarged. There was significant correlation between posterior joint space variation and occlusal increased distance. Conclusions：There are reference value of measuring TMJ space for decising the amount of occlusal increased distance.
