摘要
目的比较正畸牵引治疗不同年龄上颌埋伏阻生尖牙患者的疗效,分析年龄对正畸牵引治疗成功率的影响。方法选取135例上颌埋伏阻生尖牙患者为观察对象,根据年龄不同分为成年人组(60例)和青少年组(75例),对两组患者进行正畸牵引治疗,比较两组患者的治疗效果。结果成年组患者治疗所需要时间为(12.1±3.2)个月长于青少年组的(8.3±2.6)个月,二者比较差异有统计学意义(t=7.61,P<0.05)。成年组患者治疗总有效率(83.33%)低于青少年组(98.67%),二者比较差异有统计学意义(χ2=10.47,P<0.05)。治疗前所有患者上颌埋伏阻生尖牙未萌出到正常位置,间隙不足,牙槽嵴均未见吸收。治疗后,治疗有效患者上颌埋伏阻生尖牙萌出到位,牙体长轴正常,无明显牙根吸收,根尖周组织正常,但成年人组可见不同程度的牙龈退缩、形态不良;治疗无效患者上颌埋伏阻生尖牙萌出不到位,牙根发育异常。结论正畸牵引治疗上颌埋伏阻生尖牙,成人治疗效果低于青少年,且需要时间较长,早期发现、治疗对上颌埋伏阻生尖牙治疗具有重要意义。
Objective To compare the curative effect of orthodontic traction treatment for different age patients with maxillary embedded maxillary teeth ,and to analysis of the effect of age on orthodontic traction treatment success rate .Methods 135 cases of maxillary embedded maxillary teeth patients were selected as the observation objects ,and were divided into adult group （60 cases） and teenagers group（75 cases） according to age .The patients of the two group did orthodontic traction treatment ,then we compare the curative effect of two groups .Results The treatment time of the adult group was （12 .1 ± 3 .2）months ,which was longer than that of the teenagers group was （8 .3 ± 2 .6）months ,the comparative difference was statistically significant （t=7 .61 ,P〈0 .05） .The treatment total effective rate of the adult group was 83 .33% ,wich was less than that of the teenagers group was 98 .67% ,the com-parative difference was statistically significant （χ2 =10 .47 ,P〈0 .05） .Before treatment ,all of the patients ,the maxillary embedded maxillary teeth did not appear to its normal position ,clearance is not enough ,and alveolar ridge was no absorption .After treatment , the maxillary embedded maxillary teeth of patients with effective treatment eruption was in place ,the tooth length axis was normal , no obvious root absorption ,and periapical tissue was normal ,but the adults group patients had different level of gums shrink and bad morphology .The maxillary embedded maxillary teeth of the patients with Ineffective treatment did not reach the designated po-sition ,and root dentin dysplasia .Conclusion the orthodontic traction treatment for maxillary embedded maxillary teeth patients ,the treatment effect of the adult was less than the teenagers ,and the treatment time was longer than the teenagers .So the early detec-tion ,early treatment for maxillary embedded maxillary teeth treatment has great significance .
