If a Guide Right (TM) Surgical Template is made and guide sleeve placement is prosthetically driven, an X-Ray must be taken prior to use to verify that the angulation / position is correct and not violating the roots of the adjacent teeth (or other anatomical structures). If the angle of the guide sleeve is incorrect, the Protractor is used to indicate the difference between the existing angle and the correct angle. Set the protractor on the periapical X-Ray. Locate the guide sleeve in the X-Ray, and draw a line through the center of the existing guide sleeve. Now, draw another line through the desired placement of the guide sleeve and measure the angle between them. That difference is noted and is used to correct the guide post either by using the Guide Right Generation II Bending Tool or a pre-bent angled guide post, available in 2, 3, 4, 6, 8, 10, 12, 14, and 24 degrees.
