当上颌弓出现严重萎缩或畸形时，本文提出的方案旨在最大限度地减少对骨重建手术的干预。一名患者接受了使用钛网和微粒自体加牛脱钙骨来增强萎缩的上颌牙弓。在计算机断层扫描数据细化后，利用计算机辅助设计和计算机辅助加工来规划骨体积的增大，以改善支撑最终牙修复体所需的种植位置。增加的上颌骨在塑料中快速成型，钛网在手术干预前在该模型上进行测试。然后，将预制好的钛网植入上颌弓内，植骨。在最终的固定种植体支持的康复中，相对于种植体的位置增加了骨。本文提出的方案是一种可行的、可重复性的方法，可以为最终的种植体支持的假体康复确定正确的骨强化。
The protocol presented here is intended to minimise the intervention in bone reconstruction surgery when severe atrophy or deformity is present in the maxillary arches. A patient underwent augmentation of an atrophic maxillary arch using titanium mesh and particulate autogenous plus bovine demineralised bone. After computed tomography data elaboration, computer-aided design and computer-aided machining were used to plan the augmentation of bone volume to improve the implant position needed to support the final dental prosthesis. The augmented maxilla was rapidly prototyped in plastic, and the titanium mesh was tested on this model before the surgical intervention. Then, the preformed titanium mesh was implanted in the maxillary arch with bone grafting. The bone was augmented relative to the position of the implants for the definitive fixed implant-supported rehabilitation. The protocol presented here is a viable, reproducible way to determine the correct bone augmentation for the final implant-supported prosthetic rehabilitation.
