摘要： 数字化技术的发展和临床应用,使复合树脂精准修复伴错畸形的前牙间隙成为可能。本文报告1例数字化技术辅助下复合树脂直接粘接修复上切牙间隙伴轴向、中线、排列异常的复杂病例。患者存在牙间隙宽度不均、上下颌中线不齐、前牙排列不一致等多种美学缺陷。通过数字化技术进行美学设计并结合3D模型进行效果预示,最终在腭侧硅橡胶导板的辅助下,成功解决了患者牙列间隙伴错畸形问题。本病例为伴错畸形的牙体美学缺陷患者的治疗提供了参考。

Abstract: The development and clinical application of digital technology have made it possible to accurately restore anterior diastema with malocclusion using composite resin. This paper reported a complex case of digital technology-assisted direct bonding restoration with composite resin for maxillary incisor diastema accompanied by abnormal axial inclination, midline deviation, and irregular alignment. In this case, the patient presented multiple dental aesthetic defects, including uneven diastema width, misaligned maxillary and mandibular midlines, and irregular anterior tooth arrangement. Through aesthetic design with digital technology and effect prediction using 3D models, the problems of excessive dental diastema and malocclusion in the patient were successfully solved with the assistance of a lingual silicone rubber guide. This case provides a reference for the treatment of patients with dental aesthetic defects accompanied by malocclusion.
