A method and a device for the simplified inspection of the compatibility of the positions of master tubes in a surgical guides with respect to the positions in a predetermined plan in a computer model. For example, during virtual planning, the virtual surgical guide includes master tubes having an axis that is the axis (e.g., an installation axis) along which a dental implant will be installed. The virtual surgical guide can be manufactured, e.g., by substrative methods and additive methods. As discussed herein, the accuracy of the physical surgical guide can be checked physically or virtually.
