Anterior Copy Crown With Medit i500 Direct Import Into CAD for Design and Mill with CEREC MCXL and CORiTEC ONE

In this article, we feature an upper left lateral crown that needed to be replaced due to recurrent decay.  While the patient was getting numb, we defined the job description in the Medit i500 software and imaged the pre-existing crown, the opposing and the bite.  We digitally cropped out the tooth to be prepared and proceeded with crown removal. Once the margins were refined and the tissue was displaced, we imaged the preparation in HD mode and processed the case.

Crown Replacement Due To Recurrent Decay with Medit i500

Once the digital models were rendered, we launched the integrated CAD software that automatically imported the pre-op, the opposing, the prep model, and the bite. Their relationship is preserved in the CAD software and no modifications were necessary.  You have two ways to copy the pre-op; one way is to program the CAD software so it replicates the pre-op perfectly while the other gives you a raw proposal that you can then choose to adapt to pre-existing situation.

Direct Import of Models into CAD Software for Design and Mill

Once the case is designed in the CAD software, you can then take it to any CAM and Milling Machine to produce a restoration. Here we milled an emax restoration with the CEREC MCXL and the imes icore CORiTEC ONE at the same time so we can compare the final results.  The CEREC milling machine produced a restoration faster by about 90 seconds but the final results of the margins by the CORiTEC Machine was far superior.  Also, the CAM software, Millbox in this situation, allows us to choose a third drill that is 0.6 mm in diameter.  This increases milling time but results in less overmilling than the 1.2 mm burrs that milll the intaglio of the CEREC Machine.
