Abstract

ABSTRACTObjective To describe comprehensive orthodontic treatment, including periodontal surgery and prosthetic treatment, to manage severe disharmonious gingival margins.Case A 16-year-old man presented with chief complaints of multiple crooked teeth and a missing maxillary central incisor due to a traffic accident. He was diagnosed with Angle Class I malocclusion with severe anterior crowding and a missing upper right central incisor. We orthodontically treated him with an upper left lateral incisor, lower first premolar extractions, and transposition of the upper right lateral incisor to the central incisor using a pre-adjusted edgewise appliance. After 30 months of active orthodontic treatment, periodontal surgery, involving gingivectomy/gingivoplasty of the upper right lateral incisor, was performed for clinical crown lengthening, and a provisional restoration was fabricated. The final restoration was delivered after gingival healing. A stable occlusion with even gingival margins was obtained after 2 years of retention.Discussion and Summary This case revealed that orthodontic transposition of a lateral incisor to replace a missing central incisor could be a valid treatment option. Additionally, interdisciplinary orthodontic treatment combined with periodontal surgery and prosthetic treatment is effective to resolve severe anterior crowding with a successful esthetic and functional result.KEYWORDS: Missing toothperiodontal surgeryprosthetic treatmentinterdisciplinary orthodontic treatment AcknowledgmentsThe authors wish to thank Dr. Junya Kusumoto and Dr. Keita Yamagata for their scientific revision.Author contributionsYasuhiko Oga contributed to orthodontic treatment, conception, data acquisition, interpretation, and drafted and critically revised the manuscript.

上颌中切牙缺失和严重拥挤患者的侧切牙移位、假体治疗和牙周手术:一个跨学科的治疗策略
摘要目的介绍包括牙周手术和修复体治疗在内的综合正畸治疗方法,以治疗严重龈缘不和谐。病例一名16岁男子,主诉因交通事故导致多颗牙齿弯曲,上颌中门牙缺失。他被诊断为Angle I类错颌,前牙严重拥挤,右上中切牙缺失。我们对他进行了正畸治疗,左上侧切牙,下第一前磨牙拔出,并使用预调整的边缘器具将右上侧切牙转置到中切牙上。经过30个月的积极正畸治疗后,进行牙周手术,包括牙龈切除术/右上侧切牙牙龈成形术,用于临床冠延长,并制作临时修复。最终修复在牙龈愈合后进行。保留2年后,获得牙龈边缘均匀的稳定咬合。讨论与总结本病例提示用侧切牙置换缺失的中切牙是一种有效的治疗方法。此外,跨学科的正畸治疗结合牙周手术和假体治疗可以有效地解决严重的前牙拥挤问题,并取得成功的美学和功能结果。关键词:缺牙牙周手术;修复治疗;多学科正畸治疗作者感谢Junya Kusumoto博士和Keita Yamagata博士的科学修订。syasuhiko Oga对正畸治疗、构思、数据采集、解释做出了贡献,并起草和批判性地修改了手稿。Yoshinori Shirakata对牙周外科、数据采集、解释做出了贡献,并起草和批判性地修改了手稿。Hiroshi Tomonari对正畸治疗、概念、解释做出了贡献,并起草和批判性地修改了手稿。宫崎昭一参与了构思、数据采集、解释,并起草和批判性地修改了手稿。披露声明作者未报告潜在的利益冲突。伦理批准病人以书面形式同意发表该病例。本研究未获得任何资助。
