A full-arch rehabilitation of the edentulous upper jaw without grafting procedures exploits the residual alveolar or the basal bone, with the necessity of long implants placed with a particular orientation. The precision in planning and placing the fixtures is fundamental to avoid clinical problems and to allow an acceptable connection with the prosthesis. The computer-aided implantology resulted in more accuracy than the traditional one, with a high standard of correspondence between the virtual project and the real outcome. This paper reports about the two different digital protocols, static and dynamic, as support to implant-borne prosthetic rehabilitation of edentulous maxillae. Two pterygoid and two/four anterior standard implants were seated in both cases by two different operators, without flap raising, and immediately loaded. This approach avoided the posterior cantilever by-passing the maxillary sinus and was adequately planned and realized without any surgical or prosthetic error. The two digital flow-charts were described step by step, underlining each other's advantages and drawbacks compared to a free-hand approach.
在上颌无牙颌的全牙弓修复中，不采用植骨手术而是利用残余牙槽骨或基骨，这就需要以特定方向植入长种植体。精确的种植体规划和植入对于避免临床问题以及实现与义齿的良好连接至关重要。计算机辅助种植技术比传统技术更精确，虚拟设计与实际效果之间具有高度的一致性。本文报告了两种不同的数字方案，即静态和动态方案，以支持上颌无牙颌的种植支持式修复。在两种情况下，均由两名不同的操作者在不掀起 flap 的情况下植入两个翼突种植体和两个/四个前牙标准种植体，并立即进行加载。这种方法通过绕过上颌窦避免了后部悬臂，并且经过充分规划和实施，没有任何手术或修复错误。逐步描述了这两种数字流程图，强调了它们与徒手操作方法相比各自的优缺点。 （注：原文中“flap”可能是“黏膜瓣”等医学专业术语，但不太明确其准确含义，这里按原样翻译）
