The Dental Arts

I may be a bridgetender, but like an onion, I have many layers. I also have a degree in Dental Laboratory Technology and Management. I am fascinated with dental appliances and their fabrication. I graduated with honors. I had big dreams.

Not that those dreams went anywhere. After applying to 200 different labs with no viable offers, and after seeing that dental appliance technology is outpacing the little mom and pop labs that I hoped to be a part of, and after having a wrist surgery that would have made it extremely painful to do the fine motor movements required on a day to day basis, I wised up and went back to bridgetending.

But the fascination remains. So when I needed a crown replaced, I was delighted to see it’s entire design and creation chairside. We’ve certainly come a long way from the days when you had to get a gloopy, bad-tasting mold taken of your teeth, then come back weeks later to have a crown fitted that had been fabricated in an offsite lab.

Instead, they popped off my old crown, and took photographs of my teeth from every possible angle, and then, voila! A three-dimensional image of my teeth appeared on the computer screen. It was fascinating.

From there, Mary, the technologist, created a crown for me on screen. Make no mistake, this was no flimsy endeavor. This takes skill in both science and art. She has to have knowledge of oral anatomy and how various teeth interact with one another. And she also must create a final product that will not only be functional but also aesthetically pleasing. That’s an admirable talent.

I watched her create this tooth and enjoyed imagining her thought process. It was like digital sculpting. Leonardo da Vinci would have been intrigued. And proud.

She consulted with my dentist (a big shout out to Dr. Steven Lockett in Renton, Washington, and his entire amazing staff!) and did a few tweaks based on his suggestions, and then sent the data off to the machine for fabrication. I wish I could have seen that. I know that the machine carves the crown out of little blocks of some mysterious substance that is probably trademarked by the company that created CEREC, the CAD/CAM (computer-aided design and computer-aided manufacturing) system that my dentist uses.

I could be wrong, but I think of it kind of like 3d printing in reverse. Instead of creating things from a bead-like substance, this machine carves it down from a cube. I mean, seriously, how cool is that?

In no time flat, my crown was hot off the presses, so to speak, and ready to go into my mouth. In it went, and off I went. Just another thing checked off my to-do list. And yet, when I think of the science and artistry that went into the whole endeavor, I still am filled with awe.

By the way, one of my favorite blog posts is the one I wrote entitled Cool Stuff You Never Knew about your Teeth.  Check it out! If you don’t learn at least one thing from it, I’ll eat my hat. With my brand new crown.
