An original prosthetic planning involving CT scan is described; it provides the surgeon with a template for use during the surgical phase of osseointegrated implant treatment. The final prosthodontic reconstruction was planned in a preliminary in vitro study. The CT scan provided a three-dimensional study of the underlying bone, to determine the position, angulation, and depth of the fixture to be used. The specially developed "positioner" decreased the possibilities of error in perforating the mandible. A second CT scan verified whether there were errors in positioning the fixtures. The satisfactory results and the predictability of the final rehabilitation led to the adoption of this method in a clinical research program on human patients.
描述了一种涉及CT扫描的原始修复计划；它为外科医生提供了一个模板，以便在骨整合种植治疗的手术阶段使用。最终的修复重建是在初步的体外研究中规划的。CT扫描提供了对下方骨骼的三维研究，以确定要使用的种植体的位置、角度和深度。专门开发的“定位器”降低了下颌骨穿孔时出错的可能性。第二次CT扫描验证了种植体定位是否存在误差。最终修复的满意结果和可预测性导致该方法在一项针对人类患者的临床研究项目中被采用。
