无托槽隐形矫治器治疗牙周炎致前牙扇形移位1例报告及文献复习

Treatment of anterior teeth fan-shaped displacement caused by periodontitis with invisible orthodontic appliance without brackers:A case report and literature review

目的:观察采用无托槽隐形矫治器治疗牙周炎致前牙扇形移位患者的正畸效果,为临床正畸医生治疗该类疾病提供临床依据。方法:1例因牙周炎致前牙扇形移位患者,经牙周基础治疗待牙周情况稳定后,使用无托槽隐形矫治器进行牙周-正畸联合治疗,收集正畸治疗前后患者的面像、口内像和影像学检查资料,分析对比并结合文献复习,讨论该类患者的诊疗方案和治疗要点。结果:患者,女性,43岁,安氏Ⅱ类错[牙合]畸形同时伴有牙周炎致前牙扇形移位,采用无托槽隐形矫治器进行牙周-正畸联合治疗。对比患者矫治前后面像和口内像,可见患者牙周情况良好,正畸治疗成功压低前牙并关闭散隙,建立正常覆[牙合]覆盖及尖牙和磨牙关系。对比矫治前后影像学检查,可见患者前牙内收明显,牙槽骨高度与矫治前基本一致。结论:牙周炎致前牙扇形移位的患者采用无托槽隐形矫治器行牙周-正畸联合治疗后治疗效果良好,有利于患者牙周情况的长期稳定。

Objective:To observe the effect of invisible orthodontic appliance without brackets in the treatment of the patient with anterior teeth fan-shaped displacement caused by periodontitis,and to provide the clinical basis for the clinical orthodontists in the treatment of these patients.Methods:One patient with anterior teeth fan-shaped displacement caused by periodontitis,received the periodontal-orthodontic combination treatment with the invisible orthodontic appliance without brackets.After the periodontal basic treatment,the patient's periodontal condition was stabilized,The extraoral photographs,intraoral photographs,and imagological examination data of the patient before and after treatment were collected,combined with the literature review,the diagnotic plans,treatment plans,and key points of treatment of the patient were discussed.Results:One 43-year-old female patient with Angle Class Ⅱ malocclusion complicated with anterior teeth fan-shaped displacement caused by periodontitis received the periodontal-orthodontic combination treatment with invisible orthodontic appliances without brackets.The extraoral and intraoral photographs before and after correction were compared,the patient's periodontal condition was stable,and the orthodontic treatment successfully decreased the anterior teeth and closed the gap;the normal overjet and overbite and normal canine and molar relationship were established.The imagological examination before and after correction were compared,the anterior teeth of the patient were significantly adducted,and the height of the alveolar bone was basically the same as that before correction.Conclusion:The periodontal-orthodontic combination treatment with invisible orthodontic appliance without brackets has a good effect in the patient with fan-shaped anterior teeth displacement caused by periodontitis,which is conducive to the long-term stability of periodontal condition of the patients.
