中国山东地区正常成人颅面结构Tweed-Merrifield分析

Tweed-MerrifieId analysis for Chinese Shandong adults

目的建立山东地区正常形成Tweed—Merrifield分析法正常值。方法选择山东地区正常汉族成年人80例，男、女各40例，年龄范围为18—24岁．摄取定位侧位片，应用Tweed—Merrifield分析法进行测量并行统计学处理。结果不仅建立山东地区正常成人Tweed—Merrifield分析法各项指标正常值，并且发现FMA女性明显大于男性，后面高、前面高以及面高指数女性明显小于男性。结论建立的正常值可为山东地区成年正畸患者提供诊断依据，为矫治方案的制订作参考。
