| 摘要 目的：探讨与分析无托槽隐形矫治技术对重度牙周炎伴咬合紊乱患者临床牙周指标的影响。方法：选择2019年1月到2021年5月在本院诊治的重度牙周炎伴咬合紊乱患者90例作为研究对象，根据简单分配原则把患者分为隐形组与传统组各45例。传统组给予传统直丝弓固定矫治技术治疗，隐形组给予无托槽隐形矫治技术治疗，两组都治疗观察6个月。在矫治前及矫治6个月后观察牙周指标，并检测龈沟液中细胞因子含量。结果：治疗后隐形组的总有效率为97.8 %，与传统组的84.4 %相比显著提高（P<0.05）。治疗后两组的临床牙周指数都明显低于治疗前，隐形组与传统组相比也显著降低（P<0.05）。两组治疗后的血清IL-1β与TNF-α含量明显低于治疗前，隐形组与传统组相比也明显降低（P<0.05）。治疗期间隐形组的牙龈萎缩、牙周粘连、牙根吸收、牙釉脱矿等并发症发生率为6.7 %，明显低于传统组的24.4 %（P<0.05）。结论：无托槽隐形矫治技术早期矫治重度牙周炎伴咬合紊乱能抑制龈沟液炎症因子的表达，能改善牙龈指数与菌斑指数，提高疗效，减少并发症。 |

| ABSTRACT Objective: To explore and analyze the effect of invisible orthodontic treatment without brackets on clinical periodontal indexes in patients with severe periodontitis and occlusal disorder. Methods: A total of 90 patients with severe periodontitis and occlusal disorders who were diagnosed and treated in our hospital from January 2019 to May 2021 were selected as the research subjects. According to the simple allocation principle, the patients were divided into the invisible group and the traditional group with 45 cases each. The traditional group was treated with traditional straight wire fixation orthodontic technique, and the invisible group was treated with invisible orthodontic technique without brackets. Both groups were treated for 6 months. Periodontal indexes were observed before and 6 months after orthodontic treatment, and cytokine levels in gingival crevicular fluid were detected. Results: After treatment, the total effective rate of the invisible group was 97.8 %, which was higher than that of the traditional group (84.4 %)(P<0.05). The clinical periodontal index in both groups was lower than before treatment, and the invisible group was also lower compared to the conventional group (P<0.05). The levels of serum IL-1β and TNF-α in the two groups after treatment were lower than those before treatment(P<0.05), and the invisible group was also lower than that in the traditional group (P<0.05). During the treatment period, the incidence of complications such as gingival recession, periodontal adhesion, root resorption, and enamel demineralization in the invisible group was 6.7 %, which was lower than that in the traditional group(24.4 %)(P<0.05). Conclusion: Bracket-free invisible orthodontic treatment can inhibit the expression of inflammatory factors in gingival crevicular fluid, improve the gingival index and plaque index, promote the improvement of treatment effect and reduce complications in the early treatment of severe periodontitis with occlusal disorder. |
