exocad GmbH is now integrated with 3M®/Steinbichler® and Renishaw® scanners; labs that own these systems can upgrade to an exocad-based system for only the cost of the software.
In addition, exocad has a new touch-enabled user interface, compatible with Windows 8 devices. An enhancement to the TruSmile® add-on module allows realistic per-tooth rendering for different metal alloys and ceramics, providing the dentist with a valuable tool to increase patient acceptance of a proposed restorative design.
Note to any Lab Day Chicago attendees who tried to attend exocad’s clinics,...
VITA Suprinity, a zirconia-reinforced lithium silicate ceramic, was displayed for the first time in the U.S. at Vident’s LAB DAY exhibit. The new-generation glass ceramic has a zirconium dioxide content around 10 times that of traditional CAD/CAM glass ceramic in combination with a fine-grained and homogeneous structure. Indicated for anterior and posterior crowns, implant restorations as well as veneers, inlays and onlays, the material will be available in the U.S. later this year for the CEREC/inLab MC XL, Amann Girrbach Ceramill Motion 2 and the KaVo Arctica 2 milling systems. Call 800-828-3839 or visit vident.com.
B&D introduced ORIGIN® LIVETM Multi Zirconia, pre-shaded, multi-layered discs; each layer mimics the inherent gradations of natural teeth, including chroma, value, incisal effects and translucency. Since there’s no dipping or drying involved, the pre-shaded disks streamline production and are less technique sensitive than the coloring liquid method, according to B&D.
The company also demonstrated its new ORIGIN-Haas 5HD milling machine with improved milling strategies (ORIGIN CAM Plus+ powered by hyperDENT) for fabricating custom abutments, implant bars and implant...
PEEK—poly-ether-ether-ke-tone—was the talk of the IDS in Cologne last year; now, it’s come to the U.S. in the form of the JUVORA Dental Disc made from PEEK sourced directly and exclusively from Invibio® Biomaterial Solutions, a global leader of PEEK biomaterials. Available from JUVORA Inc., the disc received FDA clearance for milling frameworks for complete and partial removable dentures and implant overdentures earlier this year.
“PEEK has had some use historically in dental applications such as abutments and healing caps. However, now with the JUVORA Dental Disc, dental...
In early February, LMT traveled to Panthera Dental in beautiful Quebec City to learn more about this new high-tech production center and its digital product offerings, including zirconia and PEEK double-structure bars.
The buzz at the Dental Laboratory Owners Association of California’s CAD/CAM Symposium in November 2005: rapid prototyping technology. First developed in the 1980s and used in the automotive and aerospace industries, the technology had laboratory owners enthusiastic about what was called the “next generation of CAD/CAM.” Advocates said the additive technology would result in increased efficiency and less material waste.
Those forecasts were spot on. The technology continues to revolutionize the way laboratories fabricate waxups and metal restorations. And, like CAD/CAM, it’s...
In the early 1980s, industry forecasters predicted a boon in implant placement, a prediction that was premature for a market still in its infancy. Inadequate education, inconsistent techniques and unpredictable results contributed to resistance on the part of many dentists and laboratories.
However, by the time we entered the new millennium, implant treatment became the first choice in tooth replacement thanks to technical advancements, long-term success rates, and the abundance of manufacturer-provided education.
The advent of CAD/CAM and cone beam technology further impacted the precision of...
After years of speculation, CAD/CAM came to fruition in the dental laboratory in 1998 with the official U.S. launch of the Procera® AllCeram Crown, featuring an aluminum oxide coping milled at Nobel Biocare’s production facility in Sweden. The success of Procera—and the introduction of a dozen new in-lab milling systems in the early 2000s—fueled intense interest among laboratory owners and made CAD/CAM the hot topic for the unforeseeable future.
The automated manufacturing process afforded an efficient, consistent method of production and also opened the door to using zirconia,...
October 1986, IECDT, New York City: Crowds of technicians attended Dr. Francois Duret’s lecture during which he demonstrated his chairside CAD/CAM system for the first time in the U.S. Based on micro-milling technology used to make titanium microchips for computers and missile parts, the system featured a laser scanner and milling machine that could fabricate crowns, inlays, onlays and up to three-unit bridges out of Dicor® material.
Touted as the system that “has the potential to change the way dentistry is done as we know it,” some attendees were concerned that chairside...
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...

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 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...
DENTAL TEAM: Ken Upright, Oxford Crown & Bridge, LLC and Dr. Shelley Olson, DDS, FICD, Granville Family Dentistry, both in Oxford, NC
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,...
DENTAL TEAM: Gyu Cho, CDT, 3D BioCAD Milling Center, Renton, WA and Dr. Ronald Bryant, Seattle
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,...
DENTAL TEAM: Cindy Vuong and Dr. Michael DiTolla, both of Glidewell Laboratories, Newport Beach, CA
RESTORATIVE PROBLEM: The patient presented with a pre-existing discolored PFM restoration on tooth #8.
TREATMENT PLAN: Dr. DiTolla prescribed a full contour BruxZir® crown, and decided to take the opportunity to test the translucency of Glidewell Laboratories' new BruxZir™ Shaded material, which offers complete color penetration all the way through the restoration for greater shade consistency. The new material also prevents shade changes or white "show-through" after occlusal adjustment....
DENTAL TEAM: Manfred Pörnbacher and Clemens Schwerin, Dentallabor Steger, Brunico, Italy and Dr. Lyndon Cooper, Professor and Chair at the University of North Carolina, School of Dentistry, Department of Prosthodontics
RESTORATIVE PROBLEM: A young female patient lost teeth #7 through #14 in a car accident and was already wearing a provisional restoration that had resulted in pronounced jawbone atrophy.
TREATMENT PLAN: The team opted for a fixed superstructure supported by six implants at sites #7 and #8 and #11 through #14. Due to inadequate bone structure, the restoration would be an occlusally...
DENTAL TEAM: Dr. William Roddy and in-house technician Steve Coles, Flow Laboratory, Fort Worth, TX
RESTORATIVE PROBLEM: A 62-year-old female presented with implants on teeth #3, #4 and #5 and a PFM bridge placed by another dentist. The implants had been placed too far buccally and the patient was unhappy with the esthetics and thickness of the bridge. The patient's occlusal planes were also uneven, and she had another large-span anterior bridge on teeth #6 through #11 that was starting to show signs of decay at the margins.
TREATMENT PLAN: The team opted to remove both bridges and the remaining...
DENTAL TEAM: Scott Gallacher, Precision Milling Center, West Valley City, UT, and Steven Barker, DDS, Salt Lake City, UT
RESTORATIVE PROBLEM: The patient was missing a second bicuspid (#12), didn't want an implant crown and was also concerned about the reduction of the adjacent healthy teeth.
TREATMENT PLAN: To address the patient's desire for the most minimally invasive solution, the team opted for a full contour bridge with minimal retention, using ORIGIN LIVE Plus zirconia since the case required both high strength (for minimal enamel removal) and high translucency (for full contour). Dr. Barker...
DENTAL TEAM: Sven Jesse, Jesse & Frichtel Dental Labs and Dr. Edward Narcisi, DMD, both of Pittsburgh, PA
RESTORATIVE PROBLEM: The patient—the wife of one of the laboratory owners--had an existing all-ceramic restoration on tooth #30 that cracked (she had previously had a PFM crown that also chipped).
TREATMENT PLAN: Since functionality and esthetics were a priority, a Zirlux FC2 full contour zirconia crown was chosen. The laboratory prefers to use Zirlux FC2 because of its flexural strength and low wear against opposing dentition. The Zirlux FC2 system consists of five pre-shaded...
DENTAL TEAM: Janet Jones, CDT, Technical Consultant, Ivoclar Vivadent and Jenny Sy-Munoz, DDS, MSD, University at Buffalo, Buffalo, NY
RESTORATIVE PROBLEM: A 36-year-old patient presented with a request to have teeth #30 and #31 restored as recommended by his general dentist. These molars had existing large pin-retained amalgam buildups that were starting to show signs of occlusal wear.
TREAMENT PLAN: Dr. Sy-Munoz prescribed monolithic crowns made from Zenostar full contour zirconia because of its strong physical properties, pleasing esthetics and optimal biocompatibility.
DENTAL TEAM: Kazunobu Yamada, RDT, Cusp Dental Supply Co., Ltd., Nagoya, Japan and Dr. Yoshihiko Mutobe, Mutobe Dental Clinic, Osaka, Japan
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.
The pre-colored multilayered shades...
