In addition to infiltration in the buccal vestibule (Fig.2 white *), intra-ligamental injection is administered in the affected tooth with the anesthetic mentioned above (black *, for added hemostatic effect). It appears that these two measures have some measurable effect when initial osteotomy is being done with a 2 mm pilot drill (Fig.3). Hemorrhage from the extraction socket is less than usual. The trajectory of the initial osteotomy seem to be ideal.
