Premolar Anatomic Copy Case with Medit i500, exocad, and imes icore eMax Milled Restoration

August 27, 2019

In this article, we demonstrate how to manage a crown replacement on a second upper premolar with the Medit i500, exocad, and the imes icore CORiTEC ONE milling machine.  The pre-existing crown was over 2 decades old and the recession revealed a supra-gingival margin.  Furthermore, there was no room to improve the anatomy or its outline form as it was in occlusion with the opposing dentition.

A powerful design technique is the copy of the pre-existing crown. Images of the pre-op are taken while the patient is numb and its contours are copied onto the final design of the restoration.  This process usually takes a minute or so, after which we milled a size 12 emax block restoration.
