摘要
目的:分析成人上颌尖牙的阻生位置、治疗方法以及治疗效果,以期为治疗上颌尖牙埋伏阻生提供临床数据.方法:调查了2001-01/2007-12来浙江大学医学院附属第二医院口腔科就诊的错<牙合>畸形患者3390例,经全口曲面断层片和CT片确诊的上颌尖牙埋伏阻生成年患者64例(汉族),共有上颌阻生尖牙80颗.经x2检验分别比较患者性别、唇腭侧阻生以及相应治疗情况间的差异.结果:上颌尖牙阻生在正畸成年患者中约占1.89%,女性:男性为1.67:1,唇侧:腭侧为2.2:1."开隙十导萌"的方式在治疗中占主导地位."开隙+导萌"的治疗方式唇侧阻生多于腭侧阻生尖牙,而"外科手术拔除"的治疗方式腭侧阻生尖牙中的应用多于唇侧,其差异均具有统计学意义(P<0.05).结论:本次调查患者上颌尖牙埋伏阻生以女性、唇侧多见,治疗唇腭侧尖牙埋伏阻生的方法存在一定差异,治疗前准确定位,选择合适的治疗方法将取得满意、稳定的治疗效果.
Abstract
AIM: To evaluate the impaction position,frequency,sex difference and management of impacted upper canines in adult orthodontic patients. METHODS: Out of the 3390 cases with various malocclusion treated in Second Affiliated Hospital,College of Medicine,Zhejiang University from January 2001 to December 2007,64 adult patients (24 males and 40 females,80 impacted canines) with maxillary canine impaction were recruited in the present study. CT scan images and panoramic radiographies were taken before and after treatment. Chi-square test was employed to compare the difference of sex,location and treatment methods. RESULTS: The prevalence of maxillary canine impaction in Chinese adult patients in this investigation was 1.89%. The ratio between male and female was 1.67:1 and the ratio between buccal and palatal location was 2.2:1. Space-opening and surgical exposure with orthodontic alignment was the predominant treatment. Significantly more buccally impacted canines were found to have been treated by space-opening and surgical exposure while significantly more palatally impacted canines were found to have been extracted (P<0.05). CONCLUSION: This investigation shows that most buccally impacted canines are found in Chinese adult patients,especially in females. Favorable esthetic effects and good occlusion will be achieved by precise diagnosis together with well-controlled and appropriate treatment approaches.
