Abstract

Accurately recording the deficiency of the three-dimensional position of dental implants and the predetermined occlusal relationship of edentulous jaws presents a significant challenge. This study aimed to achieve a truly digital workflow of immediate full-arch implant restoration by combinedcone-beam computed tomography (CBCT), photogrammetry (PG) devices, and intraoral scanners (IOS). This approach significantly reduces patient tooth loss time, minimizes the overall “chair time”, and provides precise, comfortable, and efficient implant restoration treatment. A total of 11 edentulous patients (mean age 64.72 ± 9.83 years) were treated, and outcomes such as implant survival, prosthesis survival rates, marginal bone resorption, and incidences of complications were evaluated. The results demonstrated that immediate full-arch rehabilitation of edentulous jaws on 4 or 6 implants using a PG system is an effective, safe, and efficient approach to rehabilitation.

使用摄影测量系统在4或6个种植体上立即全弓修复无牙颌：一项长达2年随访的回顾性研究。

准确记录种植体的三维位置缺陷和无牙颌的预定咬合关系是一项重大挑战。本研究旨在通过联合锥束计算机断层扫描（CBCT）、摄影测量（PG）设备和口内扫描仪（IOS）实现即时全弓种植体修复的真正数字化工作流程。该方法显著减少了患者的牙齿脱落时间，最大限度地减少了整体“椅子时间”，提供了精确、舒适、高效的种植体修复治疗。共治疗11例无牙患者（平均年龄64.72±9.83岁），评估种植体成活率、假体成活率、边缘骨吸收、并发症发生率。结果表明，使用PG系统在4或6个种植体上立即全弓修复无牙颌是一种有效、安全、高效的修复方法。
