牙间隙是临床常见的美学缺陷。正畸治疗方案虽然微创，但耗时长，且存在复发风险。修复方式成为很好的替代治疗方案。随着数字化技术的发展，二维和三维的数字化设计可以结合口内和面部扫描图像，以及锥形束CT数据进行三维重建，实现修复效果的三维预测，使修复治疗各步骤更精确化。本文报道一例应用数字化技术助力上前牙散在间隙的患者重建微笑美学的病例，通过数字化技术指导治疗计划的制定、美学效果的预测及临床实施过程，完成瓷贴面和全冠的修复，术后6个月复查修复效果良好，改善了患者的前牙美观，获得满意的临床疗效。

Diastema is a common aesthetic defect. Orthodontic treatments, although minimally invasive, are time-consuming and carry the risk of recurrence. Prosthodontic treatment is a good alternative treatment. With the development of digital technology, 2D and 3D digital design can be combined with intraoral and facial scanning images, as well as CBCT data for 3D reconstruction, to achieve 3D prediction of restoration outcomes, and make each step more accurate. This article reported a case of scattered diastema in the anterior teeth, and being restored with digital technology to reconstruct the smile aesthetics. With the digital guidance of planning, aesthetic outcome prediction and clinical procedure, ceramic veneers and crown restorations were completed. The appearance of the patient′s anterior teeth was improved and the post-restorative outcome was satisfying at 6-month follow-up.
