Traditional Workflow with CADCAM

Patient comes in with splinted crowns that were more than a decade old. After first consultation, we arranged a second appointment for endodontic treatment and provisional crowns. I split the treatment at #23 because I assumed that the entire 9-unit anterior bridge were splinted. It wasn’t, and I could’ve saved a

Another Suprinity Test

Been giving Suprinity some love in recent weeks. Not too much though, as I’m still trying to limit its use to safer posterior regions. Despite the zirconia additives, ZLS ceramics behave more like e.max than zirconia. Aesthetics is easier to manage, while flexural strengths are up, but not by a

One Year Anniversary

A year ago, a colleague and I started the Tooth Faerie Club in response to a general lack of resources and discussion on digital dentistry. The majority of young, technologically-inclined dentists could see the apparent advantages of a digital workflow, and yet here in Taiwan, the dentists of old are

Clinical Notes on Waterlase

The patient wanted to replace her splinted PFMs with full ceramic crowns. The goals: Centrals with better dimensions High-Low-High gingival profiles After crown removal, we have two discolored abutments with metal cores. Fortunately, her original crowns were slightly in retroclination, so we have some buccal space to work with on

The Ride Does Matter

A couple of days ago, I had an interesting conversation with another dentist about the attractiveness (or lack thereof) of intraoral scanners for prosthodontists. The gist of his argument was that because the focus of prosthodontic restorations is the planning prior to the actual treatment, the only tangible benefit of

Polarized Light Photography

I’ve always wondered how some textbooks are able to get those photos with beautifully-colored tooth sections. Using them in PowerPoint presentations have become something of a trend, and I came across another one of those a couple of weeks ago. The photos themselves look like false-color images, but I knew

Notes on Masking Abutments [Part 2]

In our clinic, there is no shortage of patients coming in to replace old anterior dental restorations. The most frequent reasons for replacement are exposed metal margins and unnatural color, although splinted crowns are pretty popular as well. When the underlying tooth have gone through root canal therapy, we can oftentimes

The Road Not Taken

In light of the recent news regarding the questionable marketing tactics used by a Korean dental clinic, we have witnessed the beginning of the deep chasm forming between the aspirations of the dentist, and the desires of the patients. Small altercations have grown to a full-blown virtual war and, ironically,

Biomimetic Crown Transfer

This is an extended version of the same article on CEREC Digest.   A while back, a member of the study club came across a case report by Pascal Magne, titled: An approach to biomimetics: the natural CAD/CAM restoration: a clinical report. The report outlined a method that transferred a

Virtual Articulation Trial One

To me, the virtual articulator in the CEREC software has always been an awkward feature. On one hand, its existence is necessary to “complete” the digital workflow when compared with tradition. And yet, it seems to be virtually useless in clinical settings, when acquiring the necessary parameters can be extremely

Notes on Masking Abutments [Part 1]

One of my earliest attempts to block a severely discolored abutment came back for a follow-up appointment today. The patient was a woman in her seventies, and had fractured her ceramic crown on tooth #11. She had visited Taipei VGH, and was referred to our clinic for one-visit restoration. After

Ghost Mode One

Ghost Mode is a procedure for the single-visit treatment of multiple restorations. It requires at least two CEREC Omnicam devices to work, and allows the dental technician’s workflow to run in parallel with that of the dentist. The base idea is that the Biocopy scan of each subsequent Omnicam would be
