Thanks to a new distribution agreement, Zahn Dental now distributes 3D Systems’ micro-SLA ProJet® 1200...
Zahn Dental introduced seven new products to its Zirlux line:
Zirlux ST1 is an esthetic, strong, high-translucency zirconia that can be milled for full contour anterior and posterior crowns, bridges, frameworks and inlays; it’s available in multiple sizes and thicknesses.

Zirlux Temp is a pre-colored PMMA material for milling esthetic temporary crowns and bridges; it’s available in 98.5-mm discs and multiple thicknesses.
Zirlux Wax discs are used to create patterns for full contour cast or press ceramic restorations and diagnostic waxups.
Zirlux NP is a nickel- and beryllium-free, non-precious cobalt-based alloy available in 98.5-mm discs for milling.
Zirlux Ti is a titanium-grade material available in 98.5-mm discs for milling crowns, bridges, bars, implant applications...
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.
FABRICATION PROCESS: The teeth were prepared with minimal reductions (0.5mm axially, 1.0 occlusally, 0.5mm chamfer margins with rounded internal line angles), and impressions made. Provisional restorations were fabricated and cemented.
Casts were scanned using the 3Shape D810 scanner and the design was generated and approved. Jones chose the "Medium" shade of Zenostar Zr Translucent zirconia since the patient's shade...
At the show, Zimmer formally announced its partnership with Zfx GmbH. Zimmer now distributes Zfx products, including Zfx CAD software and scanners, and offers CAD/CAM services—including crown and bridge components, bars, and titanium and zirconia abutments—through its new Zfx milling center in Carlsbad, CA.

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 natural teeth in the arch. Additional implants were placed on teeth #6 and #11 through #14, and immediately loaded with a temporary bridge. After integration, the patient's final restoration would be a full contour, full arch, implant-supported bridge. KEROX ZircoStar zirconia in Extreme Translucent (ET) was chosen for its esthetics and ability to match natural teeth. Because of its small grain...
Zirkonzahn’s new Milling Unit Compact Line M1 includes the M1 Wet Heavy. The 5+1-axis unit features a four-fold orbit for extra stability, a necessity for milling hard metals, a six-fold tool changer as well as a wet processing function. It can process zirconia, titanium, chrome-cobalt, PMMA, wax, glass ceramics and prefabricated titanium abutments (Raw-Abutments©).

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 zirconia discs, 10 stains, six modifier pastes and a universal glaze. The pre-shaded discs allow you to produce all 16 VITA A-D shades as well as bleach shades with no dipping.
FABRICATION PROCESS: A custom shade was taken in the laboratory and Jesse completed a shade-mapping diagram, indicating the varying shades and characteristics in the occlusal, incisal, body and neck areas of the tooth. The...
Zubler USA launched its new milling wax designed for pressing and casting. The wax has the reproducibility of a sturdy milling wax while retaining the characteristics of hand wax; it’s strong enough to maintain marginal integrity during milling, but is also workable for melting, spruing or sculpting. Thanks to the material’s translucent and contrasting characteristics, design detail is more visible. Because resin can increase burnout time and cause damage to pressing ovens and contamination, the discs contain less resin and more high-quality wax for better final results.
The company also announced a new pressing course for technicians interested in applying new technology and strategies to their pressing processes.

Zubler’s new pressable lithium disilicate, conceptPress, has a flexural strength of 420 MPa and is available in 2- and 3-gram pellets; the 2-gram ingot is ideal for one to two units, reducing waste and saving on material costs. Ideal for inlays, onlays, crowns, veneers and three-unit bridges, the biocompatible material offers natural translucency and fluorescence and comes in three levels of opacity:
conceptPress D Pellets are available in 16 VITA shades, three bleach shades and are ideal for the layering and staining technique.
conceptPress ID Pellets come in five colors and, because of their higher opacity, are ideal for frameworks.
conceptPress CT Pellets offer high translucency ideal for inlays and onlays.
Due to the low viscosity of the material, the formation of a reaction layer during pressing is minimized. This process is optimized by the patented Advanced PressTM technology in the Zubler Variopress 300.e press ceramic furnace.
The company also introduced DC Ceram™...
