Luke Kahng, CDT, explains his technique for matching a custom shade for a female patient in her mid-30s who needed a new crown for tooth #8 and was specifically concerned with the esthetics and color of her smile.

In order to provide patients with a good color match for their restorations, I’ve found I need to do more than work with traditional shade tabs and photos. Here is my step-by-step technique for a 60-year-old patient who needed endodontic treatment and crowns on #9 and #10.

Two years ago, it wasn’t like Luke Kahng was running out of space, or that his laboratory—LSK121 Oral Prosthetics—was particularly outdated. But when the office condo space right next to his 10,000-sq-ft facility in Naperville, IL went into foreclosure, he quickly bought it. This was his opportunity, he thought, to expand and build the laboratory of his dreams.
His vision: wide, open spaces…a striking entrance…an inviting employee lounge…top-of-the-line operatory and seminar space…a place technicians would love to work and dental professionals would want to visit.
But after working up potential designs, he realized that even the additional 6,000 square feet of space wasn’t enough to create his vision. “I wanted more space. Did I really need it? No, but without it, the new laboratory wouldn’t have been the one I imagined,” says Kahng. So last year, he went to the other tenant in the building and negotiated to purchase...

LMT's LAB DAY EAST—the largest dental laboratory trade show on the East Coast—was the place to be to research digital technology. This year, of the 93 exhibitors, over 40 companies offered the latest scanners, milling and rapid prototyping machines, wax printers, software, materials and services, allowing attendees to see products up close and personal and comparison shop.
"We're looking to invest in a scanner and milling system—we'll be 'newbies'. Since I own a one-person lab and want to expand, I've been doing a lot of reading and research on new systems but it's key to be able to come to LAB DAY East and see them in person," said David Soto, Accurate Dental, Middletown, NY.
The show—held April 6 at the Grand Hyatt in the heart of Manhattan—also attracted seasoned digital labs that are looking to expand their existing digital portfolio. "Over the past two years, we've switched our clients over to full contour zirconia and now it's 95% of our business,"...

Luke Kahng, CDT, shares the detailed study models he fabricated based on his study of hundreds of natural teeth.
For many years, I've been interested in learning to recreate truly natural teeth shape and contour and have studied the morphology of more than 1,000 extracted teeth. Using what I observed about cusps, fossa, marginal ridges, dissection grooves, secondary anatomy, occlusion table and buccal and lingual contour, I fabricated full contour waxups, stone study models and then final porcelain restorations. For proper occlusion and cusp-to-fossa relationship, I mounted the 28 restorations on a semi-adjustable articulator to eliminate interference.
By simulating natural teeth, with proper length from root to incisal edge, we can more easily see a patient's long axis and three dimensional aspects as well as the emergence profile. The multiple colors evident in the porcelain give teeth the natural appearance we technicians constantly strive to recreate.
I use the study models to...
