It is with great sadness that we must share news of the passing of Arlo King, CDT and Director of Technical Services for DENTSPLY Prosthetics. Arlo was well-known, -liked and -respected throughout the...See more dental industry as the face and leader of DENTSPLY's laboratory technical support services. Those who knew Arlo were acutely aware of his love of the trade and strong loyalty to DENTSPLY. It was Arlo's goal to get better so he could get back to work. As he stated it in a recent text message, "I just can't go to work, so I am going to work from home." Arlo joined DENTSPLY Ceramco in 1992 at the close of his 20-year U.S. Air Force military career. It was in the military where Arlo gained his training as a dental laboratory technician and launched his dental career. The influence of his military background was apparent in Arlo's can-do, get-it-done attitude. You could always count on his no-nonsense, honest opinion. Those who knew Arlo were familiar with his great sense of humor and infectious laugh. One of his favorite stories to share was the time he had to take full-body impressions of the Air Force pilots for special gear—and it included both male and female crew. Arlo's sense of humor and genuine caring for his team, co-workers and customers made working with him a pleasure. At the core of his being, Arlo was a teacher. He was the unequivocal, go-to person for all things DENTSPLY technical. As a matter of fact, he had his own DENTSPLY Ceramco web page - "Ask Arlo". He, not only possessed technical mastery and was very patient, but he also had the gift for being able to communicate his knowledge at a level which made details easy to understand and learning less intimidating. Surely his teaching ability stemmed from his passion for learning. Give him a technical hurdle, the next chance he had, he'd be doing his homework to figure out how to solve it. This ability helped Arlo lead DENTSPLY from a traditional materials manufacturer to an integrated digital service provider. During his 21-year career with DENTSPLY, Arlo was the technical lead for the Prosthetics product portfolio. In 2001, he played a key role in the launch of Ceramco® 3, which remains a leading global porcelain system. In 2009, he worked to develop the industry's first digital denture prescription, TruRx®, which bears a U.S. patent in his name. Arlo's accomplishments list is extensive. He has lectured extensively in the U.S. and abroad. He has published articles in the major dental technical trade journals. Arlo has provided technical consult to key dental thought leaders. He has received numerous awards. Though highly regarded throughout the industry, Arlo was humble and spoke little of his lofty accomplishments. One of the accolades that meant a great deal to him was the "Excellence in Education" award, presented to him in 2008 by the National Association of Dental Labs in recognition of his outstanding educational contributions to the Dental Laboratory profession. When not working, Arlo enjoyed creating, from carpentry/remodeling to gardening to photography. He was a natural craftsman, cultivating all that he could touch around him. He took great pride in sharing that his yard didn't have a blade of grass out-of-place. Arlo also enjoyed traveling, and on-the-road for DENTSPLY was where Arlo spent many hours. For a few years, his home-away-from home was an apartment in York, PA. During this time he used to joke that he didn't care what he ate, so long as it wasn't on a paper plate! Arlo loved his family, especially his grandbabies, who were the light of his life. He rarely took vacation, but made an exception when it came to visiting his children. On behalf of Arlo's DENTSPLY global family, we extend our heart-felt condolences to Arlo's wife, Archie, sons, Rickie and David, daughter-in-laws, Doris and Lilia and his six grandchildren. We are forever grateful for Arlo's leadership and friendship which have immeasurably enriched our lives and the dental industry.

In addition to bringing speakers in house eight times a year, managers create individualized training programs for technicians, sending them to courses both locally and across the country depending on what skills they need to acquire. Knight is also very supportive of technicians seeking a CDT designation. For instance, in addition to hosting CDT tests, the lab offers a CDT Study Group that meets during the workday for two hours once a week for five months. It also covers all expenses—projector, books, wax, porcelain, etc.—as well as all CDT fees, including the testing and annual fees. Once a technician passes the test, he is awarded $500 and a spot in the “walk of honor,” a hallway that contains the technicians’ framed CDT certificates. This supportive environment may be one of the reasons that last year alone, eight Knight technicians earned a CDT designation.
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....See more 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.

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 about zirconia’s increased wear on opposing dentition, although advocates say that maintaining a high polish reduces the problem. Manufacturers continue to introduce new zirconia materials to address the question of esthetics and laboratory owners are taking note. “The days of using 20 different porcelains to build up a tooth, as the first option, are long gone. You can get esthetics out of full contour,” said renowned ceramist Lee Culp, CDT, CTO at DTI-Dental Technologies, Inc., speaking in Chicago in 2013.

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...See more 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 them tested; one of them tested positive for lead (210ppm). The media coverage fueled objections to offshore outsourcing and even breathed new life into the debate about mandatory laboratory certification and registration. The ADA announced it would do its own independent testing and released its findings a year later: scientists analyzed 44 different porcelain powders and 102 finished PFM crowns from both domestic and foreign laboratories; results ranged from below detectable to 113ppm in the powders and an average of 46ppm in the crowns. The conclusion: there are naturally occurring trace amounts of lead in porcelain, but no evidence of leaching into the mouth. Visit LMTmag.com on Monday for another LMT Memorable Moment.
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...See more 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 time, cross-linking techniques were refined, resulting in more durable acrylic teeth. Improved opalescence, translucency and shade consistency—especially among the new generation of composite teeth—further contributed to the growing use of acrylic teeth.

Tim Tyndall, CDT · February 15, 2012
For the last three years, I've been involved in titanium research and development with Precision Milling Center in West Valley City, UT, and read with interest Luke Kahng's recent article on titanium (How...See more to Fabricate an Esthetic Porcelain to Titanium Restoration, LMT November/December 2011, Click here to Read). The piece is well written and supported with excellent photography. However, I'd like to add some technique recommendations that are critical to the success of processing porcelain-fused-to-titanium restorations: When designing the framework, follow your manufacturer's instructions regarding minimal thickness, usually .4mm for anteriors and .6mm for posteriors. Metal preparations should always be done with SHP burs designed just for titanium. As Khang says, always cut in one direction and also use a maximum speed of 15,000rpm. Never use more than 2-2.5 bars or 30-35 psi of pressure when sandblasting titanium. Also, sandblast at a 45o angle and never use a particle size less than 120-150 microns of pure aluminum oxide abrasive. The article instructs you to blast the inside of the frame but first blast the outer surface prior to porcelain application; the inner surface of the abutments will be sandblasted after firing cycles to remove the oxide that forms internally. To clean the inside of the abutments, use a 50-micron-grit abrasive and blast at 2 bars or less of pressure; a larger grit size can damage the margins. After sandblasting, bench set the titanium frame for 5-10 minutes (not to exceed 30 minutes) to undergo the passivation process. This step is critical to the success of bonding to titanium; during this time, titanium naturally develops a very fine oxide layer that prevents corrosion and is the contributing factor for biocompatibility of the material. Failure to implement this step will lead to failure of the restoration. Avoid ultrasonic cleaning after sandblasting; steam cleaning is recommended by most manufacturers. GC recommends that its GC Initial Porcelain Ti™ Bonder be applied in a thin enough layer that the coping shines through. When applying the bonder, brush out pooling and thick streaks of the bonder for a thin, uniform coating. Properly fired bonder surfaceis dark and has a slightly shiny appearance; gray patches of fired bonder indicate the use of too much bonder. GC also recommends that the first layer of opaque is applied as a very thin wash on the Ti Bonder treated surface; apply additional layers as needed along with appropriate modifiers. Complete the porcelain buildup, finish contours, set occlusion and glaze. When polishing and cleaning titanium after the glaze, use polish wheels and high-shine compounds specifically designed for titanium. Polish the exposed titanium finish lines, wait 10 minutes for the passivation process to occur, then steam clean the restoration. This passivation process seals the surface of the titanium and prevents corrosion that would discolor the metal later.
