已经开发了一种使用机器数字化以及铣削和电火花腐蚀相结合的制造固定假体的替代方法。所用的数字转换器具有带球形尖端的接触探针。本研究评估了设备的准确性和从单个模具到计算机的数据传输。将机器读取的方形量规尺寸与计算机已知的物体尺寸进行比较，从而确定数字化的准确性。Procera加工和可靠的修复治疗的影响进行了讨论。
An alternative method for manufacturing fixed prostheses that uses machine digitalization and a combination of milling and spark erosion has been developed. The digitizer used has a contact probe with a ball-shaped tip. This study evaluated the accuracy of the device and the transfer of data from the individual die to the computer. The dimensions of a square gauge as read by the machine were compared with the known dimensions of the object with a computer, which allowed determination of the accuracy of the digitalization. Procera machining and the implications for reliable prosthodontic treatment are discussed.
