    The revolutionary one-visit crown: CAD/CAM not required

    Same-day dentistry is becoming increasingly popular and easier than ever ­— and the Rhondium OVC3 is leading the way.

    No doubt many of you read my Top 5 Test Drives column in the December issue. In that column, one of my favorite new products from 2017 was the OVC3. While I got a chance in December to give you a rundown of the product and why I like it, I really felt that in order to do the product justice it needed a complete article. So sit back, prop up your feet, and see how OVC3 may just be a dramatic world changer for dentistry.

    CAD/CAM in dentistry has, believe it or not, been with us now for over 30 years. I remember being in a fixed prosthetics class in the spring of my fourth year, which was 1987. I can clearly recall one of the instructors talking about a new concept for crowns that relied on “Computer Assisted Design and Computer Assisted Manufacturing,” hence CAD/CAM. During the lecture the instructor told us that while the system was in its very early stages, he could envision a time in the future when impression materials would be limited in use… if they were needed at all.

    OVC3The OVC3 process is a simple four-step process for one-visit crowns.I remember this as if it were yesterday for the simple reason that I really, really disliked taking impressions. It wasn’t that I was terrible at it. I suppose my skills were “adequate”, but the whole process (especially in the late 80s) was complicated, messy and the patients hated it. I recall thinking during the lecture “if I don’t have to take impressions, I need to buy one of those things.” It’s funny now because the “thing” didn’t even seem to have a name back then, or if it did, my instructor didn’t know what it was.

    That device became CEREC and it sure changed our world. It ushered in the entire category of digital impressions and in-office milling.

    Of course, starting around 2004-2005 we started to see an increase in the entire category of digital impressions. Then the entire product category exploded somewhere around 2010 and now we continue to see new players enter the acquisition market. We are also seeing lots of companies enter the market with mills. This allows the doctor to mix and match their preferences and budgets with what they need to accomplish their tasks.

    However, let’s stop and take a breath in this discussion. There are lots or reasons why same-day fixed prosthetics are a game changer for both patients and providers. From patient satisfaction to increased hourly profitability for offices, most of us that have been in practice for even a year or two can clearly see the why of same-day dentistry. The why questions have all been answered for a long time.

    What we, as a profession, are asking now is not “why,” but “how.” And by that I mean:

    • Selecting the proper acquisition unit

    • Selecting the proper milling unit

    • Learning to use the acquisition unit

    • Learning to use the milling unit

    • Learning the design software

    • Deciding which material/block to purchase and use

    • Deciding (somewhat based on material/block selection) do we need to purchase an oven

    • How much chair time based again on material/block selection

    • Determining what bonding system to use
