Abstract
A method for performing an inferior lift in a sinus includes preparing an initial opening in a bone including a marrow section and a hard sinus floor, the initial opening being drilled through the marrow section to a depth just prior to reaching the hard floor of the sinus. A portion of the hard sinus floor is removed using a sonic drilling device. Subsequently any remaining doughnut shaped hard floor of the sinus is removed using a second tip on the sonic drilling device that has an active portion that is substantially limited to 360 degrees about the circumference of the forward direction of the tip but without any forward cutting surface, the second tip configured to remove bone only in the lateral direction of the second tip without substantial cutting contact with the marrow section of the bone clearing a widened opening in the hard sinus floor of the bone.
