脊柱侧弯患者咬合特点的研究

The characteristics of occlusion in scoliotic patients

目的:通过分析脊柱侧弯患者错畸形的特点,探讨脊柱侧弯与错畸形的相关性。方法:以106例平均年龄16.2岁的脊柱侧弯患者和152例平均年龄15.3岁的身体姿势正常的人群为研究对象,通过口腔正畸专科检查,了解两组人群错畸形发生情况并分析其特点;用卡方检验来比较脊柱侧弯人群与正常人群错畸形有无差异性。结果:脊柱侧弯组磨牙关系不对称、尖牙关系不对称、上中线偏斜、下中线偏斜、单侧后牙反、前牙深覆、平面倾斜的发生率明显大于对照组,差异均有统计学意义(P<0.05)。脊柱侧弯组人群磨牙关系分布与对照组相比,安氏Ⅱ类亚类所占比例更大(P<0.05)。结论:脊柱侧弯患者左右不对称性的错畸形发病率较高,脊柱形态和身体姿势与颌位关系之间存在一定的内在联系。

AIM ： To investigate the characteristics of malocclusion in scoliotic patients. METHODS ： The occlusal features of 106 scoliotic patients with the mean age of 16.2 years and 152 healthy individuals with the mean age of 15.3 years were examined. Frequency distribution of malocclusion were compared by chi - square test. RE- SULTSi In scoliotic patients the frequencies of asymmetric molar relationship, asymmetric canine relationship, upper middle line deviation, lower middle line deviation, unilateral posterior crossbite, occlusal plane inclination, Angle Class ]I subgroup were higher than those in healthy individuals（P 〈 0.05 ）. CONCLUSION： Scoliosis patients have high frequency of asymmetric malocclusion. Scoliolosis is related to the malocclusion.
