A female patient, approximately 65 years old, presented with tooth #10 fractured down to the root; it was extracted and an implant was seated. She had had a gold filling on tooth #9 for nearly 45 years, and couldn’t imagine her appearance without it.
Although the gap following implantation was not provisionally restored, the gingival situation was excellent (see Figure 1). During the intraoral try-in, the crown showed good results in the cervical gingiva as well as good fit and shade match.

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
When Massoudah Faiz opened her C&B laboratory in Atlanta a decade ago, she made working chairside a core part of her business model. Currently, she works chairside for 70% of her cases.
“In the U.S., dentists and labs tend to be divorced; they need to get remarried. We’re a team and we need to understand each other better,” said Gordon Christensen, DDS, MSD, PhD, during his keynote address at the Argen Corp.’s Future of Digital Dentistry event in November.

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.

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...

The challenging aspect of this case was that one of the implants was improperly placed between #7 and #8. Steve Lee explains how he made a screw-retained zirconia framework with pink gingiva tissue to recreate the lost gingiva and then cemented on four single crowns made from IPS e.max to the framework.

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...
