中文摘要

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青少年40例为研究对象,拍摄头颅侧位片,采用传统头影测量法和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相比,下颌后缩患者∠SNB、Co-Go、Co-Pog、U1-L1减小,∠ANB、∠SN-MP、L1-MP增大,∠SNA、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。

英文摘要

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-F1 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.
