The aim of this report is to describe a technique, in which a severely resorbed edentulous mandible was restored with computer-aided design/computer-aided manufacturing (CAD/CAM) surgical guide and an implant-supported fixed dental prosthesis in two days.
The quality of life of edentulous patients is generally restricted due to functional and psychosocial problems associated with complete dentures. These issues become worse over time due to ongoing bone resorption. Implant-supported prostheses have been utilized to overcome these problems.
A 79-year-old patient with a severely resorbed edentulous maxilla and mandible presented to our clinic. After the cone beam computed tomography (CBCT) scans were performed, five implants were virtually placed via a 3-dimensional software. Then, a CAD/CAM surgical guide was fabricated with a stereolithographic method. Her mandible was restored with five implants by using the CAD/CAM surgical guide and the implant-supported prosthesis with CAD/CAM titanium framework in 2 days.
The severely resorbed edentulous mandible was successfully restored with five dental implants, and the implant-supported fixed dental prosthesis via the CAD/CAM milled titanium framework.
The technique using software and hardware portrayed in this report may be a feasible option to restore similar patients if it is executed by trained restorative dentists adhering to strict guidelines.
本报告旨在描述一种技术，即通过计算机辅助设计/计算机辅助制造（CAD/CAM）手术导板和种植体支持的固定义齿在两天内修复严重吸收的无牙下颌骨。
由于与全口义齿相关的功能和心理社会问题，无牙患者的生活质量通常受到限制。随着骨吸收的持续，这些问题会随着时间变得更糟。种植体支持的修复体已被用于克服这些问题。
一名79岁的患者，上颌骨和下颌骨严重吸收且无牙，前来我院就诊。在进行锥形束计算机断层扫描（CBCT）后，通过三维软件虚拟植入了五颗种植体。然后，采用立体光刻法制作了CAD/CAM手术导板。使用CAD/CAM手术导板和带有CAD/CAM钛框架的种植体支持义齿，在两天内用五颗种植体修复了她的下颌骨。
通过五颗牙种植体以及种植体支持的、经由CAD/CAM铣削钛框架的固定义齿，成功修复了严重吸收的无牙下颌骨。
如果由训练有素的修复牙医按照严格的指导方针执行，本报告中描述的使用软件和硬件的技术可能是修复类似患者的一种可行选择。
