Using Biogeneric Rules for Quadrant Planning
When the V3.80 software first came out, we made videos that discussed at length how the software algorithms worked to come up with your biogeneric proposal. Specifically, the software will look at the mesial 50 percent of the distal tooth (to the prep) first. If that isn't present, it will then look at the mesial tooth (50 percent of the mesial tooth to the prep). If neither is present, then the software will give you a 'generic' database proposal. These concepts are very important to understand when taking on biogeneric quadrants. You have to use these rules as a basis to which tooth should be designed first, and why. Once you understand these concepts, it will make designing biogeneric quadrants much more predictable and easy for you. The following video will illustrate this concept in detail.
