Two points, A and B, define a straight-line and, in this case, a drill trajectory. The top and bottom of a tube (or any other two points in the tube) define points A and B at the same time and keep a drill along its planned trajectory. In the ThinLayer® Guide system, the combination of our tube and ThinLayer® guides define points A and B in sequence. Initially an insertion point (Point A) is created on the gingiva (as a bleeding point) or bone (as a small pilot hole). If continuing with the tube guide, the outer diameter of each drill stop fits flush to the guide tube, creating Point B for each drill in the sequence.
But, when using the ThinLayer® Guide, the outer diameter of the disposable drill stop fits flush to the surgical guide hole, creating Point B for each drill in the sequence. When you connect these two points by putting the tip of the drill through the surgical guide hole (Point B) and into the insertion point (Point A), you now have a defined trajectory to drill and prepare the planned osteotomy.
To clarify: If there is no vertical space constraint and the insertion point is good, you may instead continue to use the tube guide through the entire sequence. The drill stops fit flush with the ThinLayer® Guide hole, as well as the tube guide.
