摘　　要：目的比较无托槽隐形矫治器与自锁托槽矫治器在口腔正畸中的应用效果及对牙周健康的影响。方法选取2020年1月至12月收治的84例行口腔正畸治疗的错颌畸形患者作为研究对象,通过随机数字表法将其分为隐形组及参照组,各42例。隐形组采取无托槽隐形矫治器治疗,参照组采取自锁托槽矫治器治疗。比较两组的临床疗效、牙周健康情况、牙根吸收分级及舒适程度。结果两组的治疗总有效率比较,差异无统计学意义(P>0.05)。矫治6个月后,两组的菌斑指数(PLI)、龈沟出血指数(SBI)评分均低于矫治前,且隐形组低于参照组(P<0.05)。隐形组的牙根吸收分级优于参照组,舒适程度评分高于参照组(P<0.05)。结论自锁托槽矫治器及无托槽隐形矫治器均为临床治疗错颌畸形的有效手段,但无托槽隐形矫治器更有利于维护患者的牙周健康,减轻牙根吸收,提升口腔舒适度。Objective To compare the application effect of bracketless invisible appliance and self-ligating bracket appliance in orthodontics and its influence on periodontal health.Methods A total of 84 patients with malocclusion who underwent orthodontics treatment from January to December 2020 were selected as the research objects.The patients were divided into invisible group and reference group by random number table method,with 42 cases in each group.The invisible group was treated with bracketless invisible appliance,and the reference group was treated with self-ligating bracket appliance.The clinical efficacy,periodontal health,root resorption grading and comfort were compared between the two groups.Results There was no significant difference in the total effective rate of treatment between the two groups(P>0.05).After 6 months of orthodontic treatment,the plaque index(PLI)and sulcus bleeding index(SBI)scores of the two groups were lower than those before treatment,and the invisible group were lower than those of the reference group(P<0.05).The root absorption grade of the invisible group was better than that of the reference group,and the comfort score was higher than that of the reference group(P<0.05).Conclusion The self-ligating bracket appliance and the bracketless invisible appliance are both effective means for clinical treatment of malocclusion,but the bracketless invisible appliance is more conducive to maintaining the patients'periodontal health,reducing root resorption,and improving oral comfort.
