不同牙周夹板联合正畸对牙周炎牙扇形移位患者面部美观的影响

Effects of different periodontal splints combined with orthodontic treatment on facial aesthetics in patients with sector displacement of periodontitis teeth

目的研究不同牙周夹板联合正畸治疗对牙周炎牙扇形移位患者的面部美观效果。方法前瞻性选取2018年4月至2020年4月湖南省第二人民医院收治的186例牙周炎牙扇形移位患者作为研究对象,采用随机数字表法将186例患者分为观察组和对照组,每组93例。两组均接受正畸治疗,观察组联合应用超强玻璃纤维牙周夹板,对照组联合应用常规牙周夹板。比较两组的治疗效果、治疗前后血清炎症因子指标(TNF-α、CRP、IL-6)及牙周袋深度、出血指数和菌斑指数,并比较两组患者满意度。结果治疗后半年和1年时,观察组的有效率达到91.40%(85/93)和100%(93/93),显著优于对照组[84.95%(79/93),95.70%(89/93),均P<0.05];两组患者治疗后半年和1年时的血清TNF-α、CRP及IL-6水平较治疗前显著降低,且观察组显著低于对照组,差异均有统计学意义(均P<0.05);两组患者治疗后的牙周袋深度、龈沟出血指数及菌斑指数亦显著低于治疗前,且观察组显著低于对照组,差异均有统计学意义(均P<0.05);治疗后半年和1年时,观察组的患者满意度分别达到91.40%(85/93)和94.62%(88/93),亦显著优于对照组[81.72%(76/93),89.25%(83/93),均P<0.05]。结论相比常规牙周夹板,联合超强玻璃纤维牙周夹板用于牙周炎牙扇形移位患者正畸治疗,能显著提高治疗效果和患者满意度。

Objective To study the facial aesthetic effect of different periodontal splints combined with orthodontic treatment for patients with sector displacement of periodontitis teeth.Methods A total of 186 patients with sector displacement of periodontitis teeth admitted to Hunan Second People′s Hospital from April 2018 to April 2020 were prospectively selected as the research objects.186 patients were divided into observation group and control group by random number table method,with 93 cases in each group.Both groups were treated with orthodontic correction.The observation group was treated with orthodontic combined with super fiberglass periodontal splint,while the control group was treated with orthodontic combined with conventional periodontal splint.The treatment effect,serum inflammatory factors[tumor necrosis factor-α(TNF-α),C-reactive protein(CRP),interleukin-6(IL-6)],periodontal pocket depth,bleeding index and plaque index before and after treatment were compared between the two groups,and the satisfaction of the two groups was compared.Results At half year and 1 year after treatment,the effective rate of the observation group was 91.40%(85/93)and 100%(93/93),which were significantly better than those of the control group[84.95%(79/93),95.70%(89/93),all P<0.05].The levels of serum TNF-α,CRP and IL-6 in the two groups at half year and 1 year after treatment were significantly lower than those before treatment(all P<0.05);the levels of serum TNF-α,CRP and IL-6 in the observation group was significantly lower than the control group,with statistically significant difference(all P<0.05).The periodontal pocket depth,bleeding index and plaque index of the two groups after treatment were also significantly lower than those before treatment(all P<0.05);the periodontal pocket depth,bleeding index and plaque index of the observation group was significantly lower than the control group,with statistically significant difference(all P<0.05).At half year and 1 year after treatment,the patients′satisfaction in the observation group reached 91.40%(85/93)and 94.62%(88/93),respectively,which was also significantly better than that in the control group[81.72%(76/93),89.25%(83/93),all P<0.05].Conclusions Compared with the conventional periodontal splint,the combination of super fiberglass periodontal splint can significantly improve the treatment effect and patient′s satisfaction.
