| 摘 要： | 目的 应用无托槽隐形矫治技术治疗因牙周病导致前牙间隙的患者,评价矫治过程中患者牙周状况的变化,以期为临床提供参考.方法 选取7例因轻、中度牙周炎导致前牙间隙的患者,矫治前患者前牙间隙为3.0～4.5 nnn,平均3.4 mm.应用无托槽隐形矫治技术进行正畸治疗,关闭前牙散在间隙.观察矫治前和矫治1、3、6个月患者牙龈探诊出血(bleeding on probing,BOP)阳性位点百分比和平均探诊深度;评价矫治前和矫治1、6个月上前牙釉质牙骨质界至牙槽嵴顶的距离(CEJ-ABC距)的变化.结果 疗程4～6个月,矫治后所有患者牙间隙完全关闭,矫治3、6个月BOP阳性位点百分比分别为1.2%,1.8%,与矫治前(0%)相比,差异均无统计学意义(P>0.05);矫治1、3、6个月患者平均探诊深度分别为(1.49±0.13)、(1.58±0.11)、(1.57±0.15)mm,与矫治前[(1.50±0.12)mm]相比,差异均无统计学意义(P>0.05).矫治1、6个月上前牙间CEJ-ABC距与矫治前相比,差异均无统计学意义(P>0.05).结论 无托槽隐形矫治技术可用于轻、中度牙周病致前牙间隙的患者,短期观察未见牙周组织损伤.

| Abstract: | Objective To treat the patients with anterior spaces caused by periodontal diseases with aligners and evaluate the periodontal conditions before and after treatment.Methods 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.Results No significant differences were found in periodontal evaluation and the CEJ-ABC distance between any two evaluated stages.Conclusions The aligners could be used in patients with anterior spaces caused by periodontal diseases.No periodontal tissue damages were found during the observation period. |
