Zirconia the Third

We’ve had the Katana STML zirconia for a while, but haven’t seen much of its use due to two reasons. One is that our version only comes in disc-form, so in order to mill it I’d have to break out the big MCX5 5-axis milling machine, instead of the much

Follow-Up on the Old Man

My oldest patient on came back for another routine check the other day, and our #21 is still holding strong! His restoration was showcased in a CEREC Digest article that I wrote early this year, and it is still one of my favorite. Here’s a photo I took this week.

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

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

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

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
