Digital intraoral scanning, although developing rapidly, is rarely used in occlusal reconstruction. To compensate for the technical drawbacks of current occlusal reconstruction techniques, such as time consumption and high technical requirements, digital intraoral scanning can be used in clinics. This report aims to provide a way of selecting the most suitable maxillo-mandibular relationship (MMR) during recovery.
A 68-year-old man with severely worn posterior teeth underwent occlusal reconstruction with fixed prosthesis using digital intraoral scanning. A series of digital models in different stages of treatment were obtained, subsequently compared, and selected using digital intraoral scanning together with traditional measurements, such as cone beam computed tomography, joint imaging, and clinical examination. Using digital intraoral scanning, the MMR in different stages of treatment was accurately recorded, which provided feasibility for deciding the best occlusal reconstruction treatment, made the treatment process easier, and improved patient satisfaction.
This case report highlights the clarity, recordability, repeatability, and selectivity of digital intraoral scanning to replicate and transfer the MMR during occlusal reconstruction, expanding new perspectives for its design, fabrication, and postoperative evaluation.
数字口内扫描尽管发展迅速，但在咬合重建中很少使用。为弥补当前咬合重建技术的技术缺陷，如耗时和高技术要求，数字口内扫描可应用于临床。本报告旨在提供一种在恢复过程中选择最合适的上下颌关系（MMR）的方法。
一名68岁后牙严重磨损的男性患者采用数字口内扫描进行了固定修复体的咬合重建。获得了一系列不同治疗阶段的数字模型，随后进行比较，并结合数字口内扫描以及传统测量方法，如锥形束计算机断层扫描、关节成像和临床检查进行选择。通过数字口内扫描，准确记录了不同治疗阶段的MMR，这为确定最佳咬合重建治疗提供了可行性，使治疗过程更简便，并提高了患者满意度。
本病例报告强调了数字口内扫描在咬合重建过程中复制和转移MMR的清晰度、可记录性、可重复性和选择性，为其设计、制作和术后评估拓展了新的视角。
