Limited Bone: O-Rings

For short bone, Neo Navi drills are longer than they are supposed to be.  Depth will be controlled by using O-rings.  For example use an O-ring at the first mark as a stopper so that we do not have to take a good look while drilling (Fig.6,7).  From that one, use 2 O-rings for the rest of way.  As mentioned earlier, remove surgical guide for sinus lift (Sinus Master Kit).  Replace the guide for implant placement.  Note that tap drill is not needed, because of the soft bone in the posterior maxilla.  Review Fig.1-5 for design, especially stopper for sinus lift at #2 and 3.
