摘要
目的:研究自锁矫治器配合种植支抗矫治成人上颌前突的临床疗效。方法:对17例成人上颌前突患者,应用自锁矫治器及种植支抗钉治疗,对治疗前后的X线头颅侧位定位片进行分析,比较治疗前后软硬组织的变化。结果:矫治后上切牙唇倾度U1-SN由164.29°±6.40°减小为154.89°±4.09°,上切牙突距U1-NA(mm)由(6.36±2.16)mm减小为(4.06±2.47)mm,上唇突距UL-EP(mm)由(3.39±3.21)mm减小为(-0.12±1.65)mm,差异有显著性。上、下齿槽座角、上颌磨牙位置、下切牙位置及唇倾度无显著性变化。结论:对成人上颌前突患者,应用自锁矫治器配合种植支抗技术可有效控制磨牙支抗、内收前牙,达到软组织侧貌美观改善。
Objective To investigate the curative self-ligating appliance and implant anchorage used for adult patients of maxillary protrusion.Methods 17 adult patients of maxillary protrusion were treated by self-ligating appliance and implant anchorage.The cephalometric data before and after were analyzed to compare the alteration of the soft and hard tissue.Results After treatment,incisor inclination decreased from 164.29°±6.40° to 154.89°±4.09°,the maxillary incisors were retracted from （6.36±2.16）mm to （4.06±2.47） mm,the upper lip points were retracted from （3.39±3.21）mm to （-0.12± 1.65）mm.The changes were statistically significant.There were no significant changes of SNA and SNB.Neither of the location of maxillary molars or mandibular incisors has significant changes.Conclusion Self-ligating appliance with implant anchorage can both effectively provide anchorage control for the maxillary molars and retract the incisors in adult patients with much improved profiles after treatment.
