Roland offered attendees a preview of its new four-axis wet mill for glass ceramic and composite resins. Officially launched at the IDS show, DWX-4W will be available later this year. It features a 60,000-rpm Jaeger spindle that supports milling of crowns, small bridges, inlays, onlays and veneers. In addition to milling on X, Y and Z axes, the unit rotates the blocks 360° on a fourth axis to support undercuts.
“The multi-pin clamp enables you to load three blocks of different materials and mill them simultaneously,” said Brian Brooks, Dental Solutions Product Manager. “This is an open system that features single-push operation; four-position ATC; color-coded control panel; and compact, built-in water filtration.”

Zubler’s new pressable lithium disilicate, conceptPress, has a flexural strength of 420 MPa and is available in 2- and 3-gram pellets; the 2-gram ingot is ideal for one to two units, reducing waste and saving on material costs. Ideal for inlays, onlays, crowns, veneers and three-unit bridges, the biocompatible material offers natural translucency and fluorescence and comes in three levels of opacity:
conceptPress D Pellets are available in 16 VITA shades, three bleach shades and are ideal for the layering and staining technique.
conceptPress ID Pellets come in five colors and, because of their higher opacity, are ideal for frameworks.
conceptPress CT Pellets offer high translucency ideal for inlays and onlays.
Due to the low viscosity of the material, the formation of a reaction layer during pressing is minimized. This process is optimized by the patented Advanced PressTM technology in the Zubler Variopress 300.e press ceramic furnace.
The company also introduced DC Ceram™...
Ivoclar launched IPS e.max Press MT lithium disilicate ceramic ingots for pressing that are in the medium translucency range, closing the gap between the HT and LT ingots. The monochromatic MT ingots are intended for restorations requiring a significantly higher brightness level than HT restorations. Given their reduced chroma, these ingots offer room for creativity to individualize the cervical region of restorations and achieve a natural-looking transition between dentin and enamel.
The IPS e.max Press MT ingots are available in two sizes in selected Bleach BL and A-D shades; can be used with the staining or cut-back technique; and are recommended for veneers, crowns and three-unit bridges (up to the second premolar as the terminal abutment). The MT ingots replace the existing IPS e.max Press Impulse Value ingots; the IPS e.max Press Impulse Opal ingots are not affected by this change.

Step ToothMaster Bay, CDT, DTG, discusses his technique for restoring the six anterior teeth for a patient who wanted to replace discolored anterior teeth with crowns that matched her natural A1 shade.
The digital transition in labs is not just about fabrication processes; the operational side of the lab business is changing too. Speakers at the 2014 DLOAC Meeting look at the continuously evolving role of the technician. Also: new products announced at the show.

An approximately 50-year old patient presented with a fracture on tooth #9 (see Figure 1). Since the root was also fractured, the tooth was extracted and a clasp-retained provisional restoration was seated (see Figure 2).
The gingival papilla was prepared prior to placing the implant in order to ensure subsequent seamless progress of the case. After placing the implant, sufficient time was left for the gingiva to regenerate, which was in perfect condition after healing (see Figure 3).
The challenging aspect of this case was to match the transparency of tooth #8. During the first firing, the basis for the transparent appearance was created with VM 13 Base Dentine layering, first with a 1:1 mixture and then with a 1:2 mixture of Base Dentine and Neutral NT. To achieve a shade close to that of tooth #8, Interno shades were applied before the second firing, and fixed with intermediate firings.
Next, neutral powder in its pure state was applied, followed...

Once she arrived in Arizona last fall, LMT Publisher Judy Fishman visited Scott Atkin, Owner of Creative Milling Dental Laboratory and CEO of Dental Lab Milling Supplies, LLC, in Scottdale, AZ, just as Bentley, Atkin’s massive Bernese Mountain Dog, was headed out for a walk with one of the staff members. Atkin “struck gold” in 2007 by adding a retail component to his business model to stay ahead of what’s trending and increase his revenue base.
“The focus for labs these days needs to be on creating win-win opportunities for themselves and their clients,” says Scott Atkin, Owner, Creative Dental Laboratory, in Scottsdale, AZ. “We know we’re moving evermore toward automated—and more commoditized—processes so, to me, that means we need to expand our services.” That’s exactly what Atkin did; in his case, offering products not to dentist-clients but to other laboratories.
It happened in one of those “meant to be”...

Tra’ Chambers had no actual laboratory experience when he opened Express Dental Laboratory in Norman, OK in December 2012. Harnessing the efficiency of CAD/CAM technology, the lab touts a two- to three-day turnaround (or same-day for its mobile service) and generated over $300,000 in revenue during its first full year in business. Now, with a staff of seven, the lab serves 118 clients and 45% of its work is completely digital. Here’s more about the lab’s growth strategies:
LMT: What made you decide to open Express Dental Laboratory without any prior laboratory experience?
Tra' Chambers: After spending three years as the Chief Operating Officer of a multi-location dental practice, I had a good idea of what was important to a dentist’s success: for one thing, it’s cash flow. I realized that if a laboratory could provide crowns to dentists in three days or less, it would improve the doctors’ cash flow significantly because they would get insurance...

As the enormous marketing potential of laminate veneers became evident, patent infringement cases began. While DenMat held various material patents, two other companies—Jaff Investment Co., owned by brothers Al and Frank Faunce, and Deneer, Inc., owned by Tom Greggs—held patents on the fabrication process.
However, many laboratories were still producing laminates on their own and this fueled a number of lawsuits and out-of-court settlements. In 1992, the issue reared its head again when laboratories around the country received letters from Yukiyo Ltd.—which had purchased an existing patent for the refractory method of fabricating porcelain veneers—saying they were infringing on the patent. Nearly five years later, the patent was declared invalid.
It wasn’t unheard of before 1985, but at the Chicago MidWinter meeting that February, cosmetic dentistry became the hottest topic around.
The concept wasn’t new; Dr. Charlie Pincus was air-firing and glazing laminate veneers for Hollywood stars back in the 1930s. But for the dental community, the timing was right. Enlightened thinking about cosmetics and new products—like DenMat’s Cerinate Laminates, Myron’s Chameleon Veneers, and Cerestore and Dicor castable ceramics—afforded the industry an opportunity to embrace metal-free dentistry. As LMT pointed out, “Our industry is on the verge of an incredible opportunity to maximize its business potential and capture the 50% of the population that never frequents the dental office.”
Cosmetic dentistry required a different type of marketing and savvy laboratories and dentists learned to sell by appealing to emotions and not focusing solely on quality or price. By the 1990s, cosmetic dentistry truly...
