Good Initial Proposals in exocad Design Software

December 24, 2018

When imaging a preparation, all you really need for a restoration to “fit’ is the contact area of the adjacent teeth (above the height of contour) and the opposing occlusal surface.

But the more you feed the computer aided design software the less work you have to do in the design of the restoration. For example, in the video below, you can see how the software automatically recognizes the adjacent teeth and a great initial proposal is rendered.

However, if you don’t capture all the data in the adjacent teeth, you will have to manually plot the adjacent teeth and spend more time in the design steps.

With exocad, the first step is to align the orientation of the arch so that the occlusal surface is directly facing you. Once the prepped arch and the opposing models are imported, then you place the margins.
With the color OBJ files from the Medit i500 it is very easy to identify the margin based on color and geometry. Once the margins are placed, the next step in the wizard is to calculate the initial proposal.
