目的比较口腔专业人士与非专业人士对于开放式及闭合式手术暴露腭侧错位尖牙矫治后3个月的美容评估。方法选取单侧腭侧错位尖牙患者70例,分别应用开放式(36例)及闭合式(34例)手术暴露的方法,采用MBT固定矫治技术排齐牙列,矫治器拆除后3个月拍摄口内照,将手术暴露侧与非手术暴露侧口内照区分开来,随机交给口腔专业人士(正畸专家12名)及非专业人士(非口腔专业人士12名),完成有关问卷调查,通过等效性检验分析,对专业人士组与非专业人士组、开放式手术暴露与闭合式手术暴露之间腭侧错位尖牙矫治后的美容效果进行评估对比。结果70例患者矫治后3个月,专业人士比非专业人士更易于辨别手术暴露的尖牙[(61.8±7.6)%vs.(48.2±3.6)%,P<0.05];两组皆认为未经手术暴露的尖牙比经手术暴露的尖牙美观效果更好,而专业人士对经两种术式暴露后的尖牙之间美观效果的辨别率无统计学差异。结论腭侧错位尖牙的排列对于美观存在一定的影响,但并不与手术暴露的术式直接相关。
Objective To compare the cosmetic assessment of oral and non-professionals for 3 months after open and closed surgical exposure of palatal dislocation canines. Methods 70 patients with unilateral palatal dislocation canine were treated by open surgery (36 cases) and closed surgery (34 cases) .Mutation of dentition was performed by MBT fixation. Three months after the appliance was removed Take photos of the mouth and separate the exposed sides of the surgery from those of the non-surgical exposures. They are randomly assigned to oral professionals (12 orthodontics experts) and non-professionals (12 non-dental professionals) to complete the questionnaire survey, Through the equivalence test analysis, the cosmetic effect of the palatal dislocation canine between the open surgical exposure and the closed surgical exposure was evaluated and compared to the group of professionals and non-professionals. Results In 70 patients 3 months after treatment, the professionals were more likely to distinguish the canine exposed than the non-professionals (61.8 ± 7.6% vs 48.2 ± 3.6%, P <0.05) The surgically exposed canine was more aesthetically pleasing than the surgically exposed canine, whereas there was no statistically significant difference in the esthetic effect between professionals after exposure to the two surgeries. Conclusion The arrangement of palatal dislocation canines has a certain impact on the appearance, but it is not directly related to the operative procedure.
