摘　　要：目的建立长春地区汉族青少年正常牙合Ricketts头影测量分析方法全部指标的正常值,并进行男女差异性的比较研究。方法在长春市各中小学进行汉族青少年个别正常牙合的普查,筛选出符合要求的个别正常牙合青少年120例:男,61例;女,59例。拍摄头颅定位侧位片,用Dolphin17.0软件测量Ricketts分析方法各项指标,SPSS17.0统计后,以均值±标准差的方法表示,并通过t检验比较各项测量指标间男、女差异性,P<0.05有统计学意义。结果得出长春地区汉族青少年正常牙合Ricketts分析法全部指标的正常值;除A点突度、上颌深度角、下颌体长度、前颅底长度性别差异有统计学意义外,其他各项指标性别差异均无统计学差异(P<0.05)。结论本研究所建立的长春地区汉族青少年正常牙合Ricketts分析方法各项测量指标的正常值可用于长春地区汉族青少年正畸患者的临床诊断、矫治设计和预后的分析。Objective To investigate the clinical normal values of the whole Ricketts analysis about cephalometry of the Han nation- ality adolescents with normal occlusion in Changchun area and to compare the craniofacial characteristics between males and females. Methods Students in elementary and middle schools of Changchun were extensively surveyed, and 120 adolescents ： 61 males, 59 females with normal occlusion were selected. Cephalometrieal films were gathered for each subject. The landmarks and cephalometric planes were determined, measurements for Ricketts were carried out with Dolphin 17.0 software. Data from 65 subjects were statistically analyzed by SPSS17.0 software with average±standard deviation. The differences between males and Females were statistically analyzed by t testing. A level of significance of 5% was assigned and P value was determined. Results The clinical normal values of the whole Ricketts analysis about cephalometry of the Han nationality adolescents with normal occlusion in Changchnn area were obtained. Ricketts analysis revealed that except for A-NPog,FH-NA ,Xi-Pm ,Anterior Cranial Length, there were no statistical differences in other values between male and female subjects （ P〈0.05 ）. Conclusion The investigation on the clinical normal values of the whole Ricketts analysis about cephalometry of the Han nationality adolescents with normal occlusion in Changehun area can be used to provide guideline for orthodontic diagnosis, treatment planning and prognosis.
