正畸修复治疗牙周病所致前牙移位的临床研究

Clinical study of orthodontic treatment for displacement of anterior tooth caused by periodontal disease

目的观察正畸修复治疗牙周病所致前牙移位的临床疗效。方法47例牙周病所致前牙松动、移位患者按治疗方法不同分为研究组（26例）和对照组（21例），研究组采用牙周基础治疗联合正畸修复治疗，对照组仅采用牙周基础治疗，观察并比较两组治疗前后的牙周袋深度、出血指数、前牙覆盖、覆胎、牙槽骨高度的变化。结果研究组治疗后的牙周袋深度、出血指数、前牙覆盖和覆耠分别为（3．12±0．53）mm、（27．30±4．25）％、（2．53±0．76）mm和（2．18±0．53）mm，均较治疗前的（5．35±0．68）mm、（97．60±7．53）％、（6．22±1．43）mm、（4．53±2．25）mm显著降低，差异有统计学意义（P〈0．05），而且下降的幅度比对照组更为明显，差异亦有统计学意义（P〈0．05）；对照组上述指标治疗后虽亦有下降，但与治疗前比较差异无统计学意义（P〉0．05）；两组治疗前后牙槽骨高度均无明显变化。结论牙周基础治疗联合正畸修复治疗能够矫正牙周病导致错位的前牙，并能稳定地改善牙周健康，有较好的应用前景。

Objective To observe the clinical efficacy of orthodontic treatment for displacement of anterior tooth caused by periodontal disease. Methods Forty-seven patients with displacement of anterior tooth caused by periodontal disease were divided into study group （26 cases） and control group （21 cases） according to the therapy method, the study group received periodontal basic treatment combined with orthodontic treatment, while the control group only received periodontal basic treatment, the changes of periodontal pocket depth, bleeding index, anterior coverage, overbite, alveolar bone height in two groups before and after treatment were observed and compared. Results The periodontal pocket depth, bleeding index, anterior coverage and overbite of study group after treatment were （3.12 ±0.53 ） mm, （27.30 ± 4.25 ）%, （2.53± 0.76 ） mm and （ 2.18 ±0.53 ）mm respectively and which were significantly lower than those before treatment [ （5.35 ± 0.68 ） mm, （97.60 - 7.53 ）%, （6.22 ± 1.43 ） mm, （4.53 ± 2.25 ） mm ], the difference was statistically significant （P 〈 0.05 ）, and the decrease extent was more obvious than the control group, the difference betwoen two groups was statistically significant （P 〈 0.05 ）; the above indicators in control group after treatment also dropped, but compared with those before treatment there was no significant difference （P 〉0.05）; the alveolar bone height in both groups had no obvious change before and after treatment. Conclusion Periodontal basic treatment combined with orthodontic treatment can correct the malposed anterior teeth, improve the periodontal conditions, it has good application prospects.
