目的 采用Delaire头影测量法分析重庆地区青少年下颌后缩患者颅颌面硬组织特征及其补偿机制,为进一步诊断、治疗设计及预后分析提供参考.方法 选取重庆地区11-14岁下颌后缩患者56例及正常(牙合)青少年40例为研究对象,拍摄头颅侧位片,采用传统头影测最法和Delaire头影测量法分析其颅颌面硬组织结构特征.结果 传统头影测量法分析发现,与正常(牙合)相比,下颌后缩患者∠SNB、Co-Go、Co-Pog、U1-L1减小,∠ANB、∠SN-MP、L1一MP增大,LSNA、Go-Pog无统计学差异.Delaire头影测量法分析发现,下颌后缩患者∠1、∠5、(Cp-Oi)/C2减小,∠2、(M-Cp)/C2、∠3、∠4增大,C3/C2、NP-F1无统计学差异;Me-F1为-8.70 mm±2.48 mm,Me-Met为5.74 mm±2.58 mm.结论 Delaire头影测量法可较直观地定量评估下颌后缩患者颅颌面骨骼结构特征及其补偿机制,下颌后缩畸形主要由下颌骨相对后移及下颌骨发育不足所致.
目的 採用Delaire頭影測量法分析重慶地區青少年下頜後縮患者顱頜麵硬組織特徵及其補償機製,為進一步診斷、治療設計及預後分析提供參攷.方法 選取重慶地區11-14歲下頜後縮患者56例及正常(牙閤)青少年40例為研究對象,拍攝頭顱側位片,採用傳統頭影測最法和Delaire頭影測量法分析其顱頜麵硬組織結構特徵.結果 傳統頭影測量法分析髮現,與正常(牙閤)相比,下頜後縮患者∠SNB、Co-Go、Co-Pog、U1-L1減小,∠ANB、∠SN-MP、L1一MP增大,LSNA、Go-Pog無統計學差異.Delaire頭影測量法分析髮現,下頜後縮患者∠1、∠5、(Cp-Oi)/C2減小,∠2、(M-Cp)/C2、∠3、∠4增大,C3/C2、NP-F1無統計學差異;Me-F1為-8.70 mm±2.48 mm,Me-Met為5.74 mm±2.58 mm.結論 Delaire頭影測量法可較直觀地定量評估下頜後縮患者顱頜麵骨骼結構特徵及其補償機製,下頜後縮畸形主要由下頜骨相對後移及下頜骨髮育不足所緻.

Objective To guide the orthodontic diagnosis,treatment planning and prognosis by analyzing the craniofacial morphology and reimbursement mechanism of young patients with mandibular retrusion in Chongqing territory by Delaire cephalometric analysis.Methods Both conventional cephalometric analysis and Delaire cephalometric analysis were conducted on the basis of the lateral cephalograms from 56 young mandibular retrusion patients and 40 teenagers with normal occlusion.Results Decreases in ∠SNB,Co-Go,Co-Pog,U1-L1 and increases in ∠ANB,∠SN -MP,L1 -MP were seen in mandibular retrusion group by conventional cephalometric analysis.Decreases in ∠1,∠5,(Cp-Oi)/C2 and increases in ∠2,(M-Cp)/C2,∠3,∠4 were seen in mandibular retrusion group by Delaire cephalometric analysis.Me-Fl and Me-Met were -8.70 mm±2.48 mm and 5.74 mm±2.58 mm respectively.Conclusion Delaire cephalometric analysis could evaluate cranio -maxillofacial architectural features of mandibular retrusion patients more visually and quantitatively,which suggests that mandibular retrusion is usually caused by the retrusion of mandibular position and the hypodevelopment of mandibule.
