Accuracy, reproducibility, and dimensional stability of additively manufactured surgical templates

CAD-CAM cobalt-chromium surgical template for static computer-aided implant surgery: A dental technique

“…5,6 However, additional laboratory and clinical studies are required to validate the accuracy of the Co-Cr surgical template and its clinical usage. 8 Limitations associated with the technique include that the overall manufacturing cost for the CAD-CAM Co-Cr surgical template is higher than that for a template made of photopolymerizing resin. In addition, the required CAM technology (DMP or CNC metal milling) is typically only available in larger commercial dental laboratories or centralized production centers.…”

“…5 Although the conventional lost-wax casting technique can be used to fabricate Co-Cr dental prostheses, CAM technologies, including computer numerical control (CNC) milling and direct metal printing (DMP), have become popular alternatives because of improved manufacturing efficiency. [6][7][8] The purpose of this report was to describe an alternative technique by using a CAD-CAM Co-Cr surgical template for s-CAIS.…”

A Novel Method for Precise Guided Hole Fabrication of Dental Implant Surgical Guide Fabricated with 3D Printing Technology

“…The development of dental digital equipment has made computer-guided implant (CGI) surgery possible [1]. The implant can be positioned using a surgical guide that is designed according to the patient's surgical plan [2]. However, the accuracy of the surgical guide is affected by the manufacturing conditions [2].…”

“…The implant can be positioned using a surgical guide that is designed according to the patient's surgical plan [2]. However, the accuracy of the surgical guide is affected by the manufacturing conditions [2]. The fabrication method (3-dimensional (3D) printing or milling), the properties of the materials (shrinkage and deformation), and the accuracy of the equipment can affect the final surgical guide, which can lead to incorrect implant positioning [2][3][4].…”

“…Numerous studies have evaluated the accuracy of the surgical guides [2][3][4][5][6]. Previous studies reported that the inaccuracies in the guided hole of the surgical guide can affect the accuracy of implant positioning [3,7,8].…”
