The new DNA of high strength glass-ceramic - CELTRA
Hanau-Wolfgang, Germany - Is it possible for a dental lab material to be as esthetic as glass-ceramic yet have high strength reserves? From now on, yes: CELTRA, the zirconia-reinforced lithium silicate (ZLS). For the first time ever, the prosthetics specialist DeguDent, Hanau, Germany and its "sister company" DENTSPLY DETREY, Constance, Germany will be presenting the new class of high strength glass-ceramic materials at the International Dental Show.
CELTRA's secret is its special DNA, the microstructure. The zirconia is atomically dissolved into the lithium silicate glass matrix so that it increases the flexural strength yet still allows esthetic shade effects to be shown to their full advantage - inclusive of the typical chameleon effect. And in addition, finely graduated opalescence, translucency and fluorescence.
DeguDent, together with their distributor DENTSPLY, will present the CELTRA CAD version, designed specifically for in-laboratory use in the inLab MC XL (Sirona, Bensheim, Germany) wet-grinding machine and the new Brain MC XL (DeguDent, Hanau, Germany). CELTRA PRESS adds a press version to the range. The CELTRA DUO presented by DENTSPLY DETREY is the version for CEREC users.
CELTRA CAD has a large amount of strength in reserve. It is quickly milled and the crystallization firings are also fast. Thus, this new class is stronger, more attractive and faster to process than comparable materials on the market. CELTRA CAD and PRESS are real plus points for ceramics - and complement zirconia ideally. This provides laboratories with an extra portion of competency where all-ceramic material and treatment concepts are concerned.
Clean and digital: Crypton turns in-lab processing of non-precious alloys into an attractive proposition
Hanau-Wolfgang - Who wouldn't like to process cobalt chrome alloys digitally? Sure, industrial networking services have been available for some time, but the real issue is: "I want to fabricate non-precious frameworks in my own laboratory with CAD/CAM. How can I do that?" Crypton from DENTSPLY, the DeguDent distributor, is an innovative material which provides a new answer because it finally allows non-precious alloys to be integrated into in-laboratory CAD/CAM processing cleanly and digitally.
Crypton fulfills a desire which numerous dental technicians have had for a long time. This is proven by the following high number: Even today, in Germany alone at least 8 million units per year are cast in non-precious alloy. This represents a high percentage within the range of dental materials even though the risks are known (e.g. inhomogeneous material, distortion). That's why there's a high demand for a digital alternative to casting non-precious alloys. One of the options is to outsource the work to a larger laboratory or industrial network service but responsible dental technicians prefer to have both options: external or in-lab fabrication. Crypton meets this need. This new sinter metal material class makes laboratories more independent and economically effective.
Crypton frameworks are designed virtually. They are wet ground using the leading machine in this field, the inLab MC XL (Sirona, Bensheim, Germany) or the new Brain MC XL (DeguDent, Hanau, Germany). The framework is initially approx. ten percent oversize before sintering, during which it shrinks exactly to its definitive dimensions. Using this principle, DeguDent made zirconium oxide (Cercon) available for processing in dental laboratories more than ten years ago and to this very day it remains the state-of-the-art procedure for ZrO2. The sintering furnaces supplied for Crypton - the orange DENTSPLY Multimat2Sinter (DeguDent distributors) and the DeguDent blue heat DUO (sold direct) both feature a double function: they can be used for Crypton and zirconium oxide frameworks and are quickly converted from one material to the other. Conventional and speed sintering are feasible for zirconia. All non-precious restorations are then veneered with the usual non-precious metal-ceramics (e.g. Duceram Kiss, Duceram love, Ceramco iC, Interaction Antagon).
Crypton blocks are available in four sizes. The smallest accommodate one or two crowns and the largest more than twenty units. The new sinter metal material class can be used for fabricating up to four-unit bridges and is an attractive proposition for labs of all sizes. Smaller labs are able to utilize more of the capacity of their inLab MC XL wet-grinding machine. Larger labs can use this type of unit for the entire fabrication process for non-precious frameworks - clean, digital and easy.
