摘要:

目的研究应用无托槽隐形矫治技术患者矫治前与矫治过程中牙周指数的变化, 并与应用传统直丝弓矫治技术患者矫治过程中牙周指数的变化进行对比, 从而评价无托槽隐形矫治技术对患者牙周健康的影响。方法选取 20~40 岁正畸患者45 例, 按矫治器类型分为A、B 两组。A 组: 25 例患者采用传统直丝弓固定矫治器矫治; B 组: 20 例患者采用无托槽隐形矫治器矫治。由同一位牙周专科医生分别检测45 例患者治疗前和治疗过程中第1、3、6 个月的各项牙周指数, 比较和分析两种矫治系统对患者牙周健康的影响。结果与矫治前相比, A 组患者矫治过程中牙周指数明显升高, B 组患者牙周指数无明显升高; 治疗过程中两组患者之间除菌斑指数有明显差异以外, 其余牙周指数并无明显差异。结论无托槽隐形矫治技术不会对患者牙周健康造成明显不良影响; 无托槽隐形矫治器比传统直丝弓固定矫治器更有利于维护口腔卫生, 但二者对患者牙周健康的影响并无明显区别。

Abstract:

Objective To evaluate periodontal health in patients during treatment with invisalign, and to compare periodontal indices in patient with conventional brackets and a series of invisible aligners. Methods Forty-five cases were randomly selected. The range for the pre-treatment age was 20 to 40 years. Forty-five patients were divided into 2 groups according to the type of appliance, which were 25 patients with conventional pre-adjusted brackets in group A and 20 patients with invisible aligners in group B. Periodontal indices, including gingival index(GI), sulcus probing depth(SPD), sulcus bleeding index(SBI), plaque index(PLI), were examined in both groups at three control visits (1st, 3rd, 6th month respective) by the same periodontal specialist. Then, compared and analysed the impacts of two appliances on the periodontal health of the patients. Results Compared with pretreatment, there was significant difference in all periodontal indices in group A except SPD, while there was no significant difference in all periodontal indices in group B during the orthodontic treatment. There was no significant difference between group A and group B during the orthodontic treatment except PLI. Conclusion Invisalign appliance could not have obvious influence on the patient’s periodontal health. Although invisialign appliance is more beneficial for the patient to keep oral hygiene, there is no significant difference on the patient’s periodontal health.
