3D CAD Dentistry

3D CAD Dentistry

“When I went to Dental School I never thought I’d be a CAD programmer”

said Dr. Marxen smiling.

As someone involved in educational technology, who writes about disruptive technologies in schools and society, there was something fascinating about my trip to the dentist today..

Less than two hours start to finish I received a new crown, as new technologies turn an old 2 WEEK process into a routine office visit. Amazing.

My Visit- A brief overview:

They used a special camera/measuring tool to image the teeth–a small wand that clicked with an image of each tooth surface. Afterward, the computer displayed a three-dimensional build of the area that looked like a detailed topographic map.

The dentist then rotated the image to inspect all the adjoining surfaces, then aligned the top and bottom teeth which included the new, virtual crown.

The technician (thank you Carol) outlined the area for the new crown on the computer much like one would use the lasso tool on Photoshop, before using a blur-like tool to remove high spots that were clearly, brightly colored on the computer image of my new crown.

After adjustments were made on the computer, the tooth was sent to the 3D milling machine in the next room. (see video below)

Eight minutes later the tooth was made. Next, it was hardened and baked white in a small kiln at nearly 900 degrees. After it cooled, sealers were applied before being cemented into place.

Dr. Marxen feels really good about the exacting nature of the technology which creates 3D manipulable images that easily allow him to see the fit around all surfaces and match in biting surfaces, prior to “printing” the crown to his Sirona Cerec 3D milling machine.  He likes the ability to maximize the time in one appointment to minimize invasiveness, reduce repeated trauma in the area of the jaw, and the safety in securing a crown immediately for protecting the affected area.


Power, Potential, and New Learning

Consider the power and capabilities of 3D printing & milling as CAD capabilities become more cost-effective and extend to other industries & institutions. How will this technology change our world?

Consider these recent news highlights:

Implications for Education?

I find the realization of this once science-fiction technology–that is now a reality, to be fascinating:

  • What will students of the (very near) future need to learn?
  • What kinds of skills and trainings will future workers people need to have to be successful in their chosen careers? Dr. Marxen didn’t expect to be a CAD programmer and now this technology has increased the effectiveness and efficiency of his practice.
  • How will values be shaped when you can create anything you’re able to conceive?
  • And alas, how will we deal with the many lawsuits/patents/hacks that will occur as the ability to imitate and own items we ‘manufacture’ at home?



NOTE: The video was taken from my cell phone (Note 3) during my visit (that’s my crown in the machine!) and edited using AndroVid Pro while sitting in the dentist chair–prior to uploading to YouTube (which took longer than finalizing and securing the crown).

educational thought leadersThank you to eSparkLearning.com for including me in their recent blog post (August 5, 2013) titled 5 Questions for 5 EdTech Thought Leaders

The article contains answers from four other educational thought leaders:

Following are the questions that were posed to us and my answers:

In your opinion, what’s the most exciting thing happening right now in digital learning?

Individualized and personalized learning that is available 24 hours a day and 7 days a week from mobile devices.

Technology versus textbooks: will there ever be a winner?

I don’t believe published paper text books to be a sound investment when there are dynamic and interactive digital options that can always be easily updated. While I may personally prefer the freely-available openness of the Internet and its vast array of resources, I understand the need for grade-level appropriate, self-contained, subject-specific digital texts. That said, I worry about student families and institutions being beholden to expensive publisher costs for eTexts.

What’s going to be the next big thing in educational technology?


If you could give one piece of advice to teachers about to integrate technology in their classroom this fall, what would it be?

Don’t hesitate because you think you have to be the controlling expert. Start small and learn alongside your class. Most importantly: Have fun!

What’s your best kept EdTech secret?

If there is an “EdTech secret”, it’s that people are the most significant ‘technology’ and that learning occurs best when powerful connections are made. Technology is simply a tool to help teachers extend their reach and for students to access content, investigate, share, and produce demonstrations of their understandings.

I really like this Haiku ‘deck’ by @connectedtchr

I’ve been talking with a lot of educational leaders lately who have ideas of throwing technology (hardware) at students but, lack a vision or inability to articulate a mind set that encompasses the philosophical shift required to move from 19th Century education to 21st Century teaching and learning.

Educational Technology is only as good as A New Mind Set needed to implement it to its full potential.

BYOD: Bring Your Own Device

In the rush to acquire the latest and greatest cell phone, what do you do with your old technology items?

In 2009, it was estimated that 5 MILLION cell phones are thrown away each year (source). While there are many opportunities to put your old cell phones to good use (example), how about donating your old cell phones, lap tops, calculators, e-readers, chargers and more to your local school, or a teacher who could use them in their classroom?

OnlineColleges.net has developed a nice infographic and list of items your BYOD school could use. With the holiday gift giving fast approaching and a record number of technology purchases being estimated, consider putting your old stuff to good use and support your local school in their BYOD efforts!

BYOD- Devices Schools Desperately Need

  1. Smartphones

    Anyone who spends even a passing second on news sites knows that more uneventful days inspire headlines along the lines of “We can’t believe there are smartphones in the classroom!” Some of the more popular devices in today’s tech-oriented curriculum, Androids, iPhones, and Blackberries (to a lesser extent) do come at a considerable cost, making it particularly difficult for low-income students to afford them. Not to mention the fact that many of the downloadables aren’t free, either. Donating a spare smartphone means allowing these kids equal access to the educational applications, augmented reality experiments, mobile social media, high-res cameras, and other tech teachers want to start incorporating into daily lessons.

  2. Tablets

    For more fiscally blessed districts, tablet computers like the iPad (probably the most popular of the lot) provide access to interactive applications and books that engage students to a greater degree than traditional methods. Like their smaller smartphone predecessors, these gadgets teach through videos, games, audio, and other multimedia. And the digital generation thrives on immersing themselves in a wide range of mediums, particularly when they involve use of many different senses. Many of which, like tactile sketchbook apps, photo editors, and high-resolution cameras, also nurture creativity while simultaneously saving on clean-up time.

  3. Laptops and PCs

    Yes, tech enthusiasts tout the emergence of tablets and other mobile computing devices as the hot new thing that will eventually oust laptops, which eventually ousted PCs. But that doesn’t mean that many schools, especially those facing tightened budgets or the inability to afford iPads for every child, couldn’t use such contributions. For BYOD classrooms already equipped with laptops and PCs, though, donated equipment like this still equalizes students along economic lines. Before wiping everything, check to see if the school will need Office or other programs that might already be loaded.

  4. iPod Touches

    iPod Touches work just fine in classroom situations where a full smartphone either proves too much of a liability concern or too costly. Users more or less enjoy access to the very same apps as those with iPhones, only without calling and text messaging capabilities. Unless classroom projects involve either of these — and most do not — the iPod Touch has a place among tech-savvy students and teachers.

  5. Wireless Routers

    So they’re not technically “devices,” but wired schools increasingly require reliable Internet access the more they ask students to start plugging in and engaging with the online world. Low-income districts in particular could use solid connections to lower the risk of downtime that might very well exacerbate the achievement gap. If a router runs perfectly fine before committing to an upgrade, check and see if any nearby schools could use it in a classroom whose current connection bubbles in and out.

  6. Wall and USB Chargers

    Again, not exactly devices, but still necessary in classrooms where smartphones, cell phones, tablets, iPod touches, and laptops remain integral components of daily lessons. It’s not like their batteries last indefinitely, after all. Many fans of these devices often wind up with extra chargers in their care thanks to forgetting to pack them before vacation, temporary losses, leaving them at a friend’s place, and other everyday memory lapses. Students permitted to tote their devices to a home that might not possess a charger will greatly appreciate the gesture.

  7. Flash Drives

    Cloud computing may be The Wave Of The Future, but not every student hails from a household with Internet. Cleaned-up (and please clean them up before donating!) flash drives let them carry their assignments from school and to home or the library for completion. Plus, it helps when the Internet goes down, in the event of one of those aforementioned classrooms with unreliable WiFi.

  8. Graphing Calculators

    Even some of the most technologically adverse districts still require their high school students to buy graphing calculators, which aren’t exactly cheap. Relevant apps are available on smartphones and tablets, of course, but obviously not every classroom involves them in the lessons. Donating old graphing calculators is an especially kind, realistic gesture on the part of graduating seniors moving on to careers or colleges that will not require them.

  9. ebook Readers

    Thanks to the emergence of e-book readers like the Kindle, Nook, etc., the back-breaking days of heavy textbooks might eventually (and thankfully) die out completely. But the up-front costs still deter many schools and students alike from transitioning over to digital, though the long-term benefits on health and finances should be rather obvious right about now. Check and see if any teachers, schools, or even districts are currently switching their classrooms out of bound books and into their digital counterparts. Unlike smartphones, uniformity isn’t as much of an issue because there are no apps with which to contend and most readers display the most common e-book file formats.

  10. Cell Phones

    Smartphones might be displacing the beeps and bloops of old-timey cellular telephones, but the old fogies still have life in them yet. They may not be able to run those applications the kids are into these days, of course. What they can do, however, is send text messages and snap photos — both of which tech-loving teachers will sometimes require. So someone out there might still need that early-2000s Motorola with the flippy top!
