A method for preparing a surgical guide for positioning of a dental implementation. The method includes positioning a positioning device relative to a model jawbone, translating the positioning device in a BL direction, adjusting a BL angle of the positioning device about a BL pivot axis corresponding to a desired position of a top of the dental implementation, and fixing the BL position, BL angle, and z-height of the positioning device. A mounting assembly mounts to the positioning device and includes a removable rotation block with a guide hole. The mounting assembly is movable in the MD direction while the BL position is fixed. A template fixes the mounting assembly for transferring the positioning information to a patient's mouth. Various aspects of the design process can be performed on a computer. The guide and a method of using the guide to perform an implant procedure are also disclosed.
