In 2007, CEREC Biogeneric, Sirona’s new biogeneric software tool for inlays and onlays, marked a major milestone in occlusal surface design. For the first time, a mathematical model extrapolated from natural tooth morphologies was deployed in order to generate patient-specific occlusal surfaces on the basis of residual tooth tissue. This significantly simplified the design of functional occlusal surfaces.

The new software version, 3.80, now available, takes biogeneric modeling a step further. It is now possible to design biogeneric occlusal surfaces for crowns, bridges and veneers. This is the result of pioneering research by Profs. Mehl and Blanz, who succeeded in identifying the genetic blueprint of morphology and occlusion and transferring their findings to an algorithmic tooth model.

In other words, the computation of the occlusal surfaces is no longer based on the residual tooth tissue. Instead, it is based on the occlusal and lateral surfaces of a morphologically and functionally intact reference tooth in the patient’s mouth — for example, the adjacent tooth, contralateral or antagonist. The software automatically analyzes the features of the reference tooth in comparison with those of an ‘average’ tooth of the same type.

The outcome is a patient-specific tooth morphology and occlusal surface design, both of which perfectly match the patient’s other teeth in terms of appearance and function. This eliminates the need for a tooth database containing standardized morphologies, which in many cases necessitates individual adjustment and milling.
