摘要
目的:比较个性化舌侧矫治与唇侧直丝弓矫治患者牙齿和骨骼关系的X线头影测量结果,为指导正畸临床选择矫治系统提供可靠的理论依据。方法:根据患者全身情况、错牙合畸形分类、牙列拥挤程度和矫治设计确定入选标准,选择临床上常见的成人错牙合畸形病例共30例。将所选患者随机分为个性化舌侧矫治组和唇侧直丝弓矫治组,每组15例。采用Steiner及Tweed头影测量分析方法进行X线头影测量,对2组患者治疗前及治疗后的头影测量数据进行对比分析,并对比2组患者的矫治疗程,评价2种不同矫治系统的治疗效果和疗程。结果:矫治结束后,2组患者磨牙及尖牙关系均为中性关系,前牙呈浅覆牙合浅覆盖,牙齿排列整齐,尖窝相对并且无余留间隙。Steiner头影测量分析,2组患者各项头影测量值比较差异均无统计学意义(P>0.05);Tweed头影测量分析,2组患者各项头影测量值比较差异均无统计学意义(P>0.05);2种分析法患者治疗前后差值比较差异亦均无统计学意义(P>0.05);2组患者临床矫治疗程比较差异无统计学意义(P>0.05)。结论:无论采用个性化舌侧矫治还是唇侧直丝弓矫治均可获得良好的牙齿排列及牙合关系,达到令人满意的临床矫治效果。
Objective To compare the X-ray cephalometric results of teeth and skeleton relationship between individual lingual orthodontic and labial straight wire orthodontics,and to provide reliable theoretical foundation for selecting orthodontic system in clinic.Methods The general conditions of the patients,classification of malocclusion,severity of denture crowding and orthodontic design were used as the selection criteria.Thirty familiar adult patients with malocclusion in clinic were divided into two groups randomly：individual lingual orthodontics group（A group）and labial straight wire orthodontics group（B group）,15cases in each group.X-ray cephalometrics were taken using Steiner and Tweed cephalometrics analysis,the results of analysis were compared between pre-treatment and post-treatment in two groups respectively,and the course of treatment in two groups was compared,too.The difference of treatment effect and course of treatment between two different orthodontic systems was evaluated.Results The relationship of first molar and canine of the patients in two groups was neutral relationship,overbite and overjet of anterior teeth was shallow,the teeth arrangement was orderly and no space was left after treatment.There was no statistically significant difference（P〉0.05）between two groups in each measured values detected by Steiner Analysis after orthodontic treatment;there was no statistically significant difference（P〉0.05）between two groups in each measured value detected by Tweed Analysis after orthodontic treatment;and there was no statistical significance（P〉0.05）in the D-values of Steiner Analysis and Tweed Analysis between two groups before and after treatment.The duration of treatment of the patients in two groups had no significant difference（P〉0.05）.Conclusion Both individual lingual orthodontics and labial straight wire orthodontics could obtain well teeth arrangement and occluding relationship and achieve satisfying clinical orthodontic outcome.
