The implant-prosthetic rehabilitation of edentulous upper jaws has always been complex for surgeons and dentists. The lack of bone in both vertical and horizontal dimension does not allow the correct insertion of dental implants. In addition, patients with edentulous upper and lower arch have a loss of vertical dimension of the face and an aged expression. Many surgical techniques have been proposed to increase the bone volume, height and thickness, such as the Le Fort I osteotomy, the bone grafts and the placement of dental implants. Planning these surgical procedures is difficult, because it is not possible to reproduce the movements of osteotomized bone segments in three planes of space. This article describes the treatment of severe atrophy maxilla with a new approach using a new instrument named "Surgiplanner". Surgiplanner is a method that, only using a computerized axial tomography (CAT), allows to obtain a totally predetermined therapeutic result from both an aesthetic and functional point of view, with surgery of severe resorbed jaws. Surgiplanner allows repositioning of segment of the skeleton of the patient's face in a predetermined and controlled way for the best implant-supported oral rehabilitation.
无牙上颌的种植修复对外科医生和牙医来说一直都很复杂。垂直和水平方向的骨量不足使得牙种植体无法正确植入。此外，上下颌无牙的患者面部垂直距离丧失且面容显老。已经提出了许多外科技术来增加骨量、高度和厚度，如勒福Ⅰ型截骨术、骨移植和牙种植体植入。规划这些外科手术很困难，因为无法在三维空间中重现截骨骨段的运动。本文介绍了一种使用名为“Surgiplanner”的新器械的新方法来治疗严重萎缩的上颌骨。Surgiplanner是一种仅使用计算机断层扫描（CAT），就能从美学和功能角度获得完全预先确定的治疗效果的方法，用于严重吸收颌骨的手术。Surgiplanner允许以预定和可控的方式重新定位患者面部骨骼的节段，以实现最佳的种植体支持的口腔修复。
