Abstract

Objective: This study presents a novel digital interproximal enamel reduction (IER) clinical procedure, aiming to improve the effectiveness of IER processes in orthodontic treatment.

Methods: A malocclusion case of skeletal-class I and angle-class I was selected for the experimental investigation. A three-dimensional (3D) model of the dentition was constructed using scanning data from a plaster model. The IER volume was measured by the overlay area of two neighboring crowns on the arranged virtual teeth. For the upper dentition, a guide plate was innovatively designed based on the original surface of the dentition and the calculated IER volume. The guide plate was fabricated using stereolithography 3D printing (SLA), and was successfully employed during the IER operation. For the lower dentition, the IER procedure was performed using the free-hand method, guided by the predesigned IER volume. Preoperative and postoperative 3D models of the dentition were compared to assess the accuracy of both IER methods.

Results: The standard deviation of upper dentition IER with guide plate was calculated as 0.13 mm, while that of lower dentition IER by freehand was 0.24 mm.

Conclusion: Through the integration of laser scanning, 3D reconstruction, virtual arrangement, guide plate design, and 3D printing, this study not only explores a novel digital IER method, but also demonstrates its clinical applicability. The findings provide compelling evidence of the method's superior accuracy in clinical practice, offering a new approach for high-precision IER operations in orthodontic treatment.

正畸指指近端间牙釉质复位的准确性评价及临床实现:一个案例研究。
目的:提出一种新型的指指近端间牙釉质复位(IER)临床方法,旨在提高IER工艺在正畸治疗中的有效性。方法:选取1例骨类、角类错颌病例进行实验研究。利用石膏模型的扫描数据构建牙列的三维(3D)模型。通过排列的虚拟牙上相邻两个牙冠的覆盖面积来测量IER体积。对于上牙列,基于牙列的原始表面和计算出的IER体积,创新性地设计了导板。采用立体光刻3D打印(SLA)技术制备导板,并成功应用于IER手术。对于下牙列,在预先设计的IER体积指导下,使用徒手方法进行IER程序。比较术前和术后牙列的3D模型,以评估两种IER方法的准确性。结果:上牙列带导板IER的标准差为0.13 mm,下牙列徒手IER的标准差为0.24 mm。结论:本研究通过激光扫描、三维重建、虚拟排列、导板设计和3D打印的结合,探索了一种新型的数字化IER方法,并证明了其临床适用性。研究结果为该方法在临床实践中的优越准确性提供了令人信服的证据,为正畸治疗中的高精度IER操作提供了新的途径。
