【摘要】：目的 :研究上海地区青少年下颌骨的生长时机及生长量。方法 :选择上海地区480例(男、女各240例)青少年X线头颅侧位定位片,按性别和颈椎骨成熟度分期法(cervical vertebral maturation method,CVM)分组、测量,应用SPSS15.0软件包计算各测量项目的均数和标准差,采用独立样本t检验比较相邻2组测量结果的差异,并计算下颌骨各生长方向上相邻生长阶段的生长量。结果:男、女下颌综合长(Co-Gn)均在CVMS1-CVMS2及CVMS3-CVMS4期间显著增长(P0.05),男性CVMS3-CVMS4期间增长量最大(P0.01),平均增长9.54 mm,女性CVMS1-CVMS2期间增长量最大(P0.01),平均增长9.09 mm。男性下颌支高度(Co-Go)在CVMS2-CVMS5期均显著增长(P0.05),以CVMS2-CVMS3期间增长量最大(P0.01),平均增长8.80 mm,女性则在CVMS1-CVMS4期间显著增长(P0.05),而最大增长量出现在CVMS1-CVMS2期间(P0.01),平均增长6.51 mm。男性下颌体长(Go-Pog)在CVMS3-CVMS4期间生长最显著(P0.01),平均增长7.55 mm;女性则在CVMS1-CVMS2期间的增长量最大(P0.01),平均增长5.73 mm。结论:男、女下颌综合长(Co-Gn)、下颌支高度(Co-Go)及下颌体长(Go-Pog)在CVM各期生长量不同,可为临床诊断及治疗方案的选择提供参考。
[Abstract]:Objective: To study the growth time and growth of juvenile mandible in Shanghai. Methods: 480 cases (male and female 240 cases, 240 cases) were selected to be grouped by sex and cervical bone maturity (cervical vertebral maturation method, CVM), and the measuring items were measured by SPSS15.0 software package. The difference between the 2 groups of 2 groups of measurements was compared with the standard deviation, and the growth of adjacent growth stages in the growth direction of the mandible was calculated. Results: male and female mandible length (Co-Gn) increased significantly (P0.05) during the period of CVMS1-CVMS2 and CVMS3-CVMS4 (P0.05), and the average increase (P0.01) during the period of male CVMS3-CVMS4 increased (P0.01). In the period of 9.54 mm, the growth of female CVMS1-CVMS2 was the largest (P0.01). The average increase of 9.09 mm. male mandibular branch height (Co-Go) increased significantly in the CVMS2-CVMS5 period (P0.05), the largest increase (P0.01) during CVMS2-CVMS3 (P0.01), an average increase of 8.80 mm, and a significant increase in CVMS1-CVMS4 (P0.05) during the period of CVMS1-CVMS4. P0.01, the average growth of 6.51 mm. male mandibular body length (Go-Pog) was the most significant growth during CVMS3-CVMS4 (P0.01), an average increase of 7.55 mm, and the largest increase in CVMS1-CVMS2 (P0.01) in women (P0.01), with an average increase of 5.73 mm. conclusions: male, female mandible length (Co-Gn), mandibular branch height (Co-Go) and mandibular body length (Go-Pog) at various stages of growth It can provide a reference for clinical diagnosis and treatment options.
