【摘要】 目的 :探讨影响上颌牙弓生长发育的因素。方法 :对 2 0例未手术腭裂患者的牙颌模型进行测量 ,并与 2 0名正常成人作对照分析。结果 :大年龄未手术腭裂患者与正常成人在尖牙区宽度存在显著性差异 (P <0 0 5 )。而上颌深度及后牙区的宽度无显著性差异 (P >0 0 5 )。结论 :在腭裂组 ,畸形的存在主要是在切牙区及尖牙区 ,对后牙区横向和垂直向的影响较小。更多还原

【Abstract】 Objective: Analysis of maxillary dental-arch development in adult unoperated cleft palate patients. Methods: Dental casts was studied in 20 cases of adult unoperated cleft palate (UCP) patients, and 20 cases of normal adults were as a control group. Results: the UCP group showed smaller dental-arch widths than a control group in the canine region (P<0 05) and these was no significant difference on upper-arch depth and posterior dental arch widths between the UCP group and a control group (P>0 05). Conclusion: In the UCP group major deformity were in incisor and canine region, and smaller interfere to posterior dental-arch widths and depth. Operation for cleft lip can interfere maxillary dental-arch development.更多还原
