To treat the patients with anterior spaces caused by periodontal diseases with aligners and evaluate the periodontal conditions before and after treatment.
Seven patients with anterior spaces ranged from 3.0 to 4.5 mm were randomly selected. All the patients were treated with aligner technique to close the spaces. Bleeding on probing (BOP) and probing depth (PD) were measured before treatment, 1 month, 3 months and 6 months after treatment. The CEJ-ABC distance was evaluated before treatment, 1 month, and 6 months after treatment.
No significant differences were found in periodontal evaluation and the CEJ-ABC distance between any two evaluated stages.
The aligners could be used in patients with anterior spaces caused by periodontal diseases. No periodontal tissue damages were found during the observation period.
使用矫治器治疗因牙周疾病导致前牙间隙的患者，并评估治疗前后的牙周状况。
随机选取7例前牙间隙在3.0至4.5毫米之间的患者。所有患者均采用矫治器技术关闭间隙。在治疗前、治疗后1个月、3个月和6个月测量探诊出血（BOP）和探诊深度（PD）。在治疗前、治疗后1个月和6个月评估釉牙骨质界 - 牙槽嵴顶（CEJ - ABC）距离。
在任何两个评估阶段之间，牙周评估和CEJ - ABC距离均未发现显著差异。
矫治器可用于因牙周疾病导致前牙间隙的患者。在观察期内未发现牙周组织损伤。
