Autocentric
(Posterior Teeth)
Linear / Planar Non-Interceptive Occlusion.
These porcelain posterior teeth originally designed by Dr. John
P. Frush can be used for all prosthetic restorations and were originally
developed to help patients with little or no lower ridge.
Non-Interceptive or Linear Occlusion uses a posterior tooth design
unlike any other in the industry. It is based on the idea that standard
cusp occlusion has a geometric classification of three-dimensions.
Geneva 2000™ linear occlusion has a one-dimensional contact between
two opposing posterior teeth. The contact occurs only in one dimension,
which is the length of a contacting blade (not a surface) of one
posterior set against the opposing flat plane posterior (see figure1).
This blade, being always in the form of a straight line, geometrically
constituting "length" in the occlusal contact without
either "width" or "depth".
The cutting blade or line is created on the lower when the posterior
are set, following the ridge, from the tuberasity to the first bicuspid
(see figure 2).
With this clinically proven technology, patients find the denture
more stable in the mouth with the elimination of the need for adhesives
and they are able to chew with more force since in any stage of
function the forces of contact are always exerted at a vertical
90° over the patient's lower ridge.
This occlusion is sometimes the only solution for problem cases
such as patients with a poor to negative ridge.
