中文摘要
目的 比较骨性Ⅰ类和骨性Ⅱ类受试者的髁突位置，为临床诊断与治疗提供指导。方法 选择50例骨性Ⅰ类受试者（A组，男 27例，女 23例，年龄 18~30岁，平均年龄26岁）和50例骨性Ⅱ类受试者（B组，男 24例，女 26例，年龄 18~28岁，平均年龄 25岁）。两组均拍摄锥形束 CT（CBCT）并应用相应软件进行测量分析，测量髁突位置相关测量项目。所有数据采用 SPSS 19.0统计学软件进行统计分析。结果 A组和 B组双侧髁突位置测量值差异无统计学意义（P>0.05）； A组前后间隙与 B组相比较，差异有统计学意义（P结论 骨性Ⅱ类受试者相对骨性Ⅰ类受试者髁突位置为居中位偏后。
英文摘要
Objective To investigate the differences in the condylar position of subjects with skeletal class Ⅰ and skeletal class Ⅱ. To provide a basis of diagnosis and treatment.Methods Group A was composed of 50 subjects with skeletal class Ⅰ(27 males and 26 females;age range=18 years to 30 years;mean age=26 years). Group B comprised 50 subjects with skeletal class Ⅱ(24 males and 26 females; age range=18 years to 28 years; mean age=25 years). The condylar position and the shapes of the condyle and the glenoid fossa were linearly measured on the sagittal and coronal sections by cone-beam computed tomography (CBCT). Data were analyzed by SPSS 19.0.ResultsNo statistically significant differences were found in the measurements of the condylar position between the sides of each group on the sagittal plane and the coronal plane (P>0.05). There were significant differences on the anterior space and the posterior space between group A and B (PConclusionThe subjectsof skeletalclass Ⅰ show an anteriorcondyleposition. The subjectsof skeletal class Ⅱ show a posterior condyleposition.
