Clinical Impressions of Cadent iTero

I couldn't resist using the word impression in the title of this post. That's because the Cadent iTero is a digital imaging system that eliminates the need for impressions for fixed prosthetics. The penetration in dentistry of these types of devices is pretty low currently, but I can foresee big things for the iTero.

We just finished 2 days of training on the device and I have come away very impressed with what I have seen so far. The process is simple, much more simple than most doctors think, and the speed and ease of workflow are already changing things a bit in my office. When you add in the fact that you can tell people they will not have their mouths filled with multiple rounds of "goop" you've got one more reason to consider this device.

I pushed the envelope a bit during training, just to see what the device could do while the trainer was there. The ultimate was today with a distal margin on a lower first molar that had a 4-6mm subgingival finish. I sculpted the tissue back with a laser and was pleasantly surprised when the iTero easily captured the margin with no problems at all.

Patient acceptance? Outstanding. Not having to suffer through impressions is a big plus for patients.

Of course the real indication of the device's quality will be when I receive the crowns back from the lab. Cadent tells me they have over 90% of their restorations being seated with no adjustments. That is a huge advantage over traditional methodologies. If that proves to be the case, we will begin to shrink our impression material inventory.

I'll report back on the seating and cementing, but so far I've got to say that it's been an impressive two days with the Cadent iTero.
