With today’s focus on highly cosmetic restorations and appliances, patients want functional, natural-looking removable partial dentures. Proper material selection is a key part of ensuring patient satisfaction.

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...January 13 at 11:06 am in How to Use VITA VM 13 for Challenging Anterior Metal-Ceramic Restorations

After meeting at LAB DAY West 2013, Sully Samartzis invited LMT’s Judy Fishman to visit his laboratory when she arrived in Arizona later that year. The laboratory is a pristine addition to a gorgeously appointed home, designed by wife Debbie, a professional interior decorator.
In 1999, Sully Samartzis had a toothache on #13. Treatment meant a root canal procedure followed by a crown. Of Greek descent, he’d only been in the U.S. for three months, arriving here from Germany with a degree in electronics and $1,400 to his name.

Tra’ Chambers had no actual laboratory experience when he opened Express Dental Laboratory in Norman, OK in December 2012.

Since their introduction in the 1950s, PFM restorations have been the bread-and-butter of C&B and most full service laboratories. In fact, as recently as 2005, only 17% of C&B workloads were metal-free. However, with the proliferation of metal-free materials and technologies, we’re nearing the tipping point: 45% of C&B workloads are now comprised of metal-free restorations, according to LMT’s 2013 Porcelain Survey.
The full contour zirconia trend began in 2009, with the launch of Glidewell’s BruxZir® Solid Zirconia crowns and bridges, marketed as a “virtually unbreakable” option for bruxers and grinders. Other manufacturers began to follow suit and introduce their own solid zirconia options and “Full Z” has become the fastest growing restoration in laboratories across the country.
The restorations allow laboratories to offer a lower-cost solution, and the labor-saving digital process ensures better fits and fewer remakes. There remains concern among some laboratory owners...
Foreign Dental Work Put to Test, an investigative report about lead found in restorations made in China was the talk of the industry when it aired in February 2008 on Ohio’s WBNS 10TV. The story covered an Ohio woman who had experienced pain and infection in her jaw after her dentist placed an ill-fitting, three-unit PFM bridge the previous year. After learning the bridge was made in China, she had the bridge removed and tested for hazardous materials, and lead (160ppm) was found in the restoration.
In addition, the TV station ordered eight PFM crowns from four labs in China and also had...

For years, porcelain was the material of choice for denture teeth because of its ability to replicate the appearance of natural dentition. But as we entered the 1990s, acrylic denture teeth had replaced porcelain as the industry standard; in fact, the use of porcelain teeth had dropped 50% during the previous decade.
Acrylic teeth offered several functional advantages: they were kinder to opposing dentition with less trauma to the bone and offered easier occlusal adjustment. However, earlier materials tended to craze and check and weren’t as esthetic as the tried-and-true porcelain. Over...
Renfert’s Cim Ozyurt explains the R&D behind lay:art style brushes, designed to fulfill all the requirements of optimal porcelain buildup.
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...
In the 1970s, a buzzer on a porcelain furnace was considered a luxury gadget. Back then, many insisted that a true ceramist should be monitoring the progress of the bake by eye, not depending on a buzzer to tell you when the case is ready.However, by the end of 1984, an LMT survey found that two-thirds of porcelain furnaces used in dental laboratories were either partially or fully automatic. LMT then observed, “modern technology has brought us computerized furnaces with features not even thought of just a few years ago, but the prices for these units are considerable.” Many small labs...

How to Match Central Incisors Using a Jacket Crown and Laminate Veneer Made With Noritake EX-3 Porcelain
Mismatched central incisors are a relatively common scenario, and a source of distress to the patient. Despite the high occurrence of these cases, it remains technically challenging for the technician and dentist alike to restore two central incisors that are esthetically balanced while being true to form and function. In addition, the complexity of the case is magnified by the fact that very often, each incisor requires different treatment.

RESTORATIVE PROBLEM: A female patient fractured the entire facial surface and buccal cusp of tooth #4, which had an old MOD amalgam restoration. Due to a 2mm diastema, the entire mesial aspect of the crown would be exposed in the patient's smile, so shade quality was a foremost concern.
TREATMENT PLAN: Because of her positive experiences with the material, Dr. Olson prescribed a Delta Zirconia full contour crown to restore tooth #4. High Translucent Delta Zirconia,...

RESTORATIVE PROBLEM: The patient presented with severe occlusal wear on his natural teeth; the lower anterior teeth were also very crooked and discolored. The existing crowns also exhibited wear, tissue retraction, dark margins and uneven shades from one crown to the next. Teeth #5, #12 and #14 were missing, requiring implants.
TREATMENT PLAN: A full-mouth restoration with 28 units was proposed and had full compliance from the patient. The team opted to use gold-hue abutments to provide a very natural,...

RESTORATIVE PROBLEM: The patient had a full cast crown on tooth #30 but wanted a more esthetic appearance.
TREATMENT PLAN: The dental team opted for a full contour zirconia restoration using the new Katana Zirconia ML, a gradational multilayered zirconia disc with four layers of color--35% enamel, 15% of the first gradation layer, 15% of the second gradation layer and 35% dentin--that offers the look of layered porcelain.
