Thoughts From the Bench – Entry #7

With my increased use of MiYo® liquid ceramics, I was able to attend the first hands on advanced course on MiYo® offered in the United States, presented by James Choi on September 17th-19th, 2020.

Truly an amazing material, and changing how we can finish any ceramic!

Where has the time gone?!

I would like to discuss the PFM ceramics system I have been forced to acquire. When I say “forced”, I mean once again, the company supplying the system I have been using has stopped manufacturing that system without warning. At the beginning of my adventure into building my own dental lab, I chose a great porcelain system that was formulated very well, and the manufacturer offered great technical support. I was very excited about what I could do with that porcelain. In time though, this company decided to sell off its dental ceramics division to another large dental supply company, and the quality of the porcelain started to noticeably change. I ended up temporarily using three different porcelain systems, until I found satisfaction with the one that was recently discontinued.

I am able to state today, that the new system I am now using is GREAT! It handles similarly to that first system I began with and liked so much. I can even say that it has better formulations of some modifiers and shoulder porcelains, which makes it fun to create PFM restorations. There is still a place for the porcelain fused to metal restoration, and I am excited to say that I have a fantastic porcelain system to create them!

Have you heard of MiYO®? More and more, you will. It is the new material developed by Jensen to add texture, color, and translucency to monolithic zirconia. MiYO® also works great on lithium disilicate glass and PFM ceramic. I have been using this product since it was introduced 1 1/2 years ago. The results I am seeing are amazing! They are so different from the stains we have had to use up until now! Look for the restorations that are more lifelike. MiYO® may have a lot to do with their superior aesthetics!

We made LiSi Press veneers to close the space and remedy the situation. Color and characterizations were added with MiYo liquid ceramic.

In this edition of Thoughts From the Bench, I would like to explore with you the reason why I have three DEMCO Polisher/Grinders in the lab.

DEMCO Polisher/Grinder Model B-1

Each polisher/grinder is placed in different areas of the lab. In the model department, I use it to shape and bevel the model that was pulled from the impression, and ground down on the model trimmer. After pins are placed, and the base is poured, this polisher/grinder is used to refine the holes of the pins on the bottom of the base. A higher speed is used with a diamond separating disk to separate sections of the models. After sectioning, the individual dies begin the die-trimming process. I have found the DEMCO Polisher/Grinder is a wonderful tool, because no matter what part of the process I am currently involved with, I have the most control of the work piece. With the thumb and index finger of both hands, I am able to very carefully manipulate the die during the rough trim with an arbor band, followed by a secondary trim with a burr.

When using a hand-piece, one hand is holding the hand-piece; the die is held by only the thumb and possibly two fingers of the other hand. This is a not the firmest, or the most stable way of holding the work piece, and can result in an inaccurate trim. No longer do we ditch the dies in the process of trimming the margin. Especially, for those that are to be scanned.

The third phase of my die-trimming is done with a Bard-Parker scalpel with a #15 blade. During each one of these steps, I am wearing my 3.5 diopter loops.
