摘要
目的评价正畸正颌联合治疗对骨性Ⅲ类错[牙合]畸形患者治疗前后面容改善的效果,研究正畸医师和普通人群对其治疗前后面容改善的美学评分。方法选择45例正畸正颌联合治疗的骨性Ⅲ类错[牙合]畸形患者,采集治疗前、后的正面及右侧90°侧位照各一张,选择37位评价者分别对该45例患者的照片作视觉模拟评分(Visual analogue scale/score,VAS)。收集45例患者术前及术后的CBCT数据,使用Dolphin imaging 11.0软件重建头颅侧位片,根据Holdaway分析法定点并测量各项指标,比较术前术后各指标间差异。结果骨性Ⅲ类错[牙合]畸形患者正畸正颌联合治疗术前与术后VAS评分有统计学意义(P<0.05),正畸医生与普通人群对术前术后的VAS评分有统计学意义(P<0.05)。Holdaway分析法分析各项测量值,术前及术后部分指标间有显著性差异。结论正畸正颌联合治疗对于骨性Ⅲ类错[牙合]畸形患者正面及侧面软组织均有显著改善,正畸医生对于骨性Ⅲ类患者治疗前后面容的评分要求均高于普通人群。
Objective To analyze the facial changes and the esthetic scores among different groups of evaluators in patients with skeletal ClassⅢmalocclusion before and after orthodontic orthognathic surgical treatment.Methods The study included forty-five patients with skeletal ClassⅢmalocclusion who accepted orthodontic orthognathic treatment.Thirty-seven were selected by using visual analogy score(VAS)method to score these patients’frontal and 90-degree-right profile photos of presurgical and postsurgical orthodontic treatment.Cone Beam CTs(CBCT)were taken before and after treatment.The lateral cephalometric radiographs were rebuilt by Dolphin imaging 11.0 and measured with Holdaway analytical method.Then the differences between all the indexes were compared.Results Patients’VAS scores were greatly improved after orthodontic orthognathic treatment(P<0.05).There were significant differences between orthodontists and layperson(P<0.05).Part of values of Holdaway analytical method were statistically different before and after treatment.Conclusion Orthodontic orthognathic treatment can greatly improve the frontal and lateral faces of patients with skeletal ClassⅢmalocclusion.Orthodontists'aesthetic scores on these patients are generally lower than layperson.
