CAPTEK is a non-oxidizing PFM system for copings and bridge frameworks. Captek can be fabricated in-house with simple web-based training or purchased complete through many certified regional outsource...See more centers. The Captek brand is appreciated by dentists and laboratories for the productâs excellent esthetics, biocompatibility, strength, versatility and cost control. It was voted by dentists as the "Townie Choice" for best PFM restoration for seven consecutive years and received a JDT "Wow" award in 2008 and 2010.
Known for its ceramic, veneering and framework materials, NORITAKE manufactures EX-3 for PFM restorations, CZR for zirconia, and CZR Press and EX-3 Press for pressable systems. Available exclusively through...See more Zahn Dental, these quality porcelains provide ease of handling, natural color matching, excellent translucency, and resistance to fracture and chipping.

Invented by Dr. Itzhak Shoher and Aharon Whiteman, CDT, first-generation Captek™ was introduced to the international dental community in 1993. The unique capillary technology took the PFM world by...See more storm because it produced a high noble metal coping right on the refractory die without casting. Dentists and technicians alike were taken by its resulting thin, gold-colored copings and ability to maximize soft tissue health; Captek remains an ideal option for patients with any type of predisposition to caries or perio concerns. In 2007, Captek Nano™—stronger and thinner than the original materials—was introduced. The technology was sold to Argen in 2011 and, soon after, the company introduced Digital Captek, a 3D-printing service. Visit LMTmag.com tomorrow for another LMT Memorable Moment.
Although PFMs were still considered by many to be the esthetic standard for clinical longevity, pressable ceramics—starting with IPS Empress and Optimal Pressable Glass (OPC)—began to drive...See more the metal-free dentistry movement in the late 1980s. The improved esthetics and biocompatibility—coupled with soaring precious metal prices—quickly made the pressable technique a successful and cost-effective way to fabricate metal-free restorations. Later, the technique was adapted to create press-to-metal and press-to-zirconia restorations. Visit LMTmag.com on Monday for another LMT Memorable Moment.
LMT took six impressions of the same prep and anonymously sent them to six different laboratories along with prescriptions for non-precious PFM crowns; one was made in the Philippines. In this ground-breaking...See more experiment in 1985—with LMT Publisher Judy Fishman as the patient—we wanted to know: could a dentist tell the difference between the $35 crown and the $75 crown? Among our panel of dentists, no one crown was rated head and shoulders above the rest. Although not uniform in their assessments, the dentists could not discern which was the most expensive and which was the least; in fact, several of them rated medium-priced crowns better than the higher-priced ones. The Crown Experiment—an LMT tradition repeated three more times in our history—demonstrated that when dentists choose a laboratory, perception is as much a factor as the quality of the crown itself, proving the value of laboratory positioning and marketing. In 2007, we kicked it up a notch and created The Crown Challenge, which invited readers to use a duplicate model to fabricate the same PFM unit as the one featured in LMT’s latest Crown Experiment. The response was overwhelming: 228 readers took us up on the challenge—LMT had to rent extra office space to accommodate the entries and the judging!—and a panel of evaluators chose sixteen finalists and four favorites based on a multitude of technical criteria.

DENTAL TEAM: Scott Atkin, Creative Dental Laboratory and Dr. Michael Foley, both in Scottsdale, AZ RESTORATIVE PROBLEM: A 79-year-old male patient with an existing PFM full mouth rehab needed a classic...See more A3 shade replacement bridge for teeth #11 through #15. TREATMENT PLAN: A five-unit Crystal Diamond full contour bridge was prescribed. Crystal Diamond was chosen for its excellent translucency and strength, ideal for highly esthetic anterior and posterior metal-free restorations. FABRICATION PROCESS: The case was scanned using a 3Shape D710 scanner and milled using Delcam software on a DentMill 4 milling machine from Digital Dental Lab. After milling, Atkin infiltrated the non-colored zirconia with a combination of Tanaka Zircolor and Zirkonzahn's Color Liquids Prettau® Aquarell shading liquids using green micro-brushes to ensure uniform application of the shading liquids. The technique, based on the instructional Shading Techniques DVD provided by Dental Laboratory Milling Supplies, allows for gradient transitional shading and high translucency. The sintering process must take into account the type of zirconia used and the number of restorations sintered at one time. Crystal Diamond is a high-heat zirconia, and generally the larger the mass and weight--like this five-unit bridge--the longer the heat-soak temperature. The accuracy and programmability of a sintering oven is key to achieving esthetic results for full contour zirconia; the laboratory used the high-temp Sintermax TI700 from Sintering Ovens.com and a custom ramp and heat-soak program specifically for long-span, full contour bridges. Zirkonzahn Zirconia Stains and Glaze were used post-sintering to endow natural tooth characteristics. Except for using different temperatures, the staining and glazing method was the same as those used with other ceramic restorations. Because of the underlying shades and gradients created using pre-sintering shading liquids, very little staining was needed on the final restoration. The patient and the doctor were pleased with the results and the fact that the color of the solid zirconia bridge matches the adjacent PFM restorations.
