Using moderate to heavy pressure, the tips if the caliper are then applied through the dense soft tissue overlying the gonial angles until they sit on the bone. It is often helpful to start with the caliper's tips situated just behind/below the angle and then move the tips slowly forward/upward until they slip laterally onto the surface of the angle.
