Based on dental insurance no waiting the tear go maxillary fissures of which we commonly call the ham Euler notches that tear go maxillary notches will give us a sense of the horizontal plane since we really had no opportunity to compare this to the patient’s pupils which is the more traditional doing it um dental insurance no waiting each tooth is hollow ground out on the back of it because.
I want you to be able to take that tooth and move it backwards if you need to without having to pop the tooth out and grind on it here’s an example if you look at the denture tooth on the left and our WIT tooth on the right you’ll see that it has its Hollow ground in the upper the lower is left intact so that if we need to position that tooth and labia version .
We have some anatomic anatomy there so that the truth can be turned and still have it look natural as I said the central incisors are set using the IP measurement we use that millimeter measurement that comes from from the literature to set the teeth in an anterior posterior direction and we positioned the lower third of the central incisors so that surface is perpendicular to.
The occlusion plane the canines are set in a similar way remember we measure the the width of the nose so we have the sense laterally where to position the teeth and we’ve developed the occlusion plane so we know where to put the incision tips that sent off the canines but there is also another thing we can use anatomically.
Which really helps us it’s been shown that % of canines are positioned where they’re incision tip is on a line that bisects the incisive papilla and is perpendicular to the midlife of the palate in other words now we’ve positioned those canines in three dimensions all on the computer remember the .
Width we use the width of the nose that gives us Sun sense they’re the arch form is shaped by by the shape of the maxillary cast or maxillary impression and the mandibular teeth are shaped to follow those maxillary teeth in other words the maxillary teeth.
