Customer voicesUserevaluationInternational field testfindings completed in 2016.“The material is very nice towork with, the veneeringis very homogeneous andexhibits little shrinkage.A very nice system yieldingwonderful results.”“Easy processing, excellent andreproducible results.”“Stain and glaze full contourworked very well.”“As far as product overall– very nice.”“The translucent appearanceincreases with the lustre!““Looks were pleasing.”“Stain and glaze full contourworked very well.”“The restorations look great.The entire ceramic restorationappears sturdy!”“A super investment.The best!”“Our expectationswere exceeded!“

EXPERTS CONCLUSIONSI think that Celtra is awesomebecause it simply fits; sprawlingand pressing are safe and simplebecause there is hardly any reactionlayer that has to be removed, andbecause you actually get the shadethat is written on the box.”Thomas BartschTRIODONT Zahntechnik GmbHEschweiler GermanyThe processing characteristics ofthe material are sensational: Itsexcellent flow properties simplifythe process and help save time.Sprueing is greatly simplified, asonly a single sprue is needed, andthere is only a minimal reactionlayer when using the new Celtrapress investment, resulting in a verysmooth surface. Rapid heating andextremely precise expansion controlprovide an excellent fit, which cutsdown significantly on the time tocompletion at the lab. In short:Significantly higher productivity inthe laboratory.Both the pressing and the veneeringceramics of Celtra Press were veryuser-friendly in their handling. Theeasy handling of both materials,the resulting time savings and theexcellent esthetic results are animportant factor in my decisionsto oft for using Celtra Press on apermanent basis.”Dental technicians no longerbelieve everything they are told.But Celtra Press, a truly impressivenew material, easily convincesand helps regain their confidencewith its incredible esthetics thatreflects the shade environment, itsunrivaled excellence of fit and highlyeconomical production methods.”Andreas KahlCreativ ZahntechnikDarmstadt GermanyWerner GotschDental Studio GotschMarktleuthen GermanyI have full confidence in Celtra Pressbecause it offers significantly morestrength – more than 500 MPa –than any otherwise comparablematerial. Its extremely high fractureresistance has been documentedin studies conducted by theuniversities of Heidelberg andRegensburg.Implementing Celtra Press in ourlaboratory was extremely easy – theuser manual is lucid and easyto understand and all the steps areeasy to follow.Anyone who has ever worked withpressable ceramic will be able tohandle this new material straightaway.Dr. Mischa KrebsAlzey GermanyMarkus GirardiGirardi ZahntechnikLudwigsburg Germany”””Markus StorkStork ZahntechnikBraunschweig Germany– 23 –

Celtra The structure makesthe differenceCeltra Duo is the first zirconiareinforced glass ceramic CAD/CAM block we developed andbrought to market. Here, thezirconium oxide is not presentin crystalline form, so the glassceramics does not appear opaque;rather, it brings out the optimumbalance of translucency andopalescence of the prostheticrestoration.This is a benefit that we wantedto replicate in a high-strengthpressable ceramic material for thedental laboratory. In fact, we evenmade it stronger.Having a number of patentsworldwide for our uniquecomposition of materials, wewere able to build on this with aninterdisciplinary team of scientistsand engineers to develop our newconcept of zirconia-reinforcedlithium silicate ceramics (ZLS).Dr. Markus VollmannDirector Research & Development,Dentsply Sirona ProstheticsCOMPARISON OF MICROSTRUCTURES ZLS versus LS2UNPRESSED INGOTSmaller crystal length in pelletresults in easier flow duringpressing of the restoration.Celtra Press ingot MT A2Etched surface(Lithium Silicate crystal 0.5 µm)Conventional LS₂ Press ingot HT A2Etched surface(Lithium Disilicate crystal 1.8 µm)PRESSED MATERIALSmaller crystals leads toeasier polishing.Celtra Press ingot MT A2Etched surface(Lithium Silicate crystal 1.4 µm, LithiumPhosphate 0.3 µm)Conventional LS₂ ingot HT A2Etched surface(Lithium Disilicate crystal 4.2 µm)

Celtra Press – The highest level of estheticsmimicking natural dentitionStrong chameleon effect(in-vivo blending)High shade coverage rateand seamless insertion ofthe restorationCeltra Press retains all the esthetic advantages of Celtra Duo, such asstrong opalescence regardless of shade paired with a level of translucencythat is adequate to exploit the chameleon effect in the mouth. The reducedcrystal size is designed within visible light wavelength to mimick lightscattering behavior of natural teeth.In other words: Just a few shades are sufficient to achieve a high coveragerate and seamless insertion of the restoration in the mouth. We evenmanaged to increase its strength significantly and to raise it to new levels.This is owed to the particular characteristics of zirconia-reinforced glassmatrix that you do not get with conventional lithium disilicate ceramics.Special featuresIn developing Celtra Press, we are extremely proud to deliver a newmaterial innovation that meets our stated goals. This is possible by a uniquemicrostructure.Smart portfolio saves timeand money Amazing esthetic properties that closely mimick a patient‘s naturalteeth Simplified system with fewer necessary components Optimized components eliminating conventional process steps Increased strength to provide confidence Exceptional flow characteristics improving pressing accuracy Incredibly robust, easy to use veneering and individualization systemsSimplify the daily work inthe labIt is these things that simplify the daily work at the laboratory, somethingthat should not be underestimated. With Celtra Press we have achievedall this, and we examined every factor in comprehensive testing includinga large-scale international field test with valuable feedback from theworkbenches of dental laboratories around the world.Special investment compoundWe have developed a new investment capable of high-speed investingthat reduces the difficult-to-remove reaction layer to almost zero thicknessin combination with the lower pressing temperature of Celtra Press of860 C. This has the advantage of better fit (no additional layer needs tobe removed) and faster processing. The formation of a reaction layer issuppressed during the pressing process, which in turn simplifies the labwork.Celtra veneering ceramicsHowever esthetic Celtra Press may be – a custom build-up may still bepreferred in the anterior region and accomplished with a veneer.With Celtra Ceram and its individual masses we can offer the rightcustomization tool, which is additionally compatible with all standardlithium disilicate ceramics. The low firing temperature of 760 C speedsup the process of making an individual crown. The developers primarilyconcentrated on: Simple shade reproduction Shade fidelity Robust processing behaviorDynamic aging testsThe range of different masses available ensures a high customizationpotential for both syst
