EDOT™ incorporates these foundations.

Functional Occlusal Cusp (FOC)

Functional Occlusal Cusp harmony relationship of opposing teeth in all functional ranges and movements that will provide the greatest masticatory efficiency without causing undue strain or trauma on the supporting tissues. Prominent cusps on the masticating surfaces and are designed to articulate with the teeth of the opposing natural or prosthetic dentition. FOC are the lingual cusp of the upper posterior and the buccal cusp of the lower posterior teeth.

Centric Stops (Centric Landing Pads)

Centric stop: opposing cuspal/fossae contacts that maintain the occlusal vertical dimension between the opposing arches. The word fossae are an anatomical pit, groove, or depression.

The EDOT ™ system the centric stops do not contact into a fossae, but into a flat surface (pad) that does not hit on any inclined plane in diameter of about 1mm at the end of a prominent cusp curvature or a marginal ridge in a horizontal plane passing though a tooth at right angles to its long axis maintain the occlusal vertical dimension between the opposing arches. (Centric Landing Pads).

The Ideal Occlusion Patterns

There are three "Ideal Occlusion Patterns" Developed by Dr. James Carlson, the shape of the ideal anteroposterior curve (curve of Spee) of the plane of occlusion is directly correlated to the angle of the articular eminence. This gives us the compassed to give you the best occlusal plane for occlusal harmony for your patients.

Curve of Spee

The Anteroposterior Curve: The anatomic curve established by the occlusal alignment of the teeth, as projected onto the median plane, beginning with the cusp tip of the mandibular canine and following the buccal cusp tips of the premolar and molar teeth, continuing through the anterior border of the mandibular ramus, ending with the anterior-most portion of the mandibular condyle.

Curve of Wilson

The Mediolateral Curve: in the theory that occlusion should be spherical, the curvature of the cusps as projected on the frontal plane expressed in both arches; the curve in the lower arch being concave and the upper arch being convex. The curvature in the lower arch is affected by an equal lingual inclination of the right and left molars so that the tip points of the corresponding cross-aligned cusps can be placed into the circumferences of a circle. The transverse cuspal curvature of the upper teeth is affected by the equal buccal inclinations of their long axes.

'F' point

A three dimensional point in space located on the midline, at the incisal edge, in between the upper central incisors. It is a very important reference point which is needed to determine the relative position of the plane of occlusion and the alignment of the upper teeth. This gives DPI a starting a point to give you the best occlusal plane on the maxillary for occlusal harmony for your patients.

Golden Shimbashi

The Shimbashi measurements were named after Dr. Hank Shimbashi. Laying down a comprehensive program that was simple and straightforward for the Dental Profession and Auxiliaries to follow, including reasoning why the procedures were done in this particular pattern. "If You Can Measure It, It's A Fact Other Wise It's Just An Opinion"
- Dr. Bernard Jankelson Result from all there search and tabulation completed, was the establishment of the most sought after anterior vertical that happened to be universal in youth, middle age, seniors and In all races. Our standard measurement Is the distance from the normal crest of the gingival of the opposing mandibular incisor. The measurement averaged out to

****19mm plus or minus 10% ****

The Golden proportion for anteriors then was put together with the Shimbashi measurement. We are now able to give you the exact size, height, and length of the anteriors to go with the patents occlusal vertical dimension measurements. This gives us the compassed to give you the best anterior function and aesthetics for Functional Occlusal Harmony for your patients.
