I 41 industry report _ Tizian system I CAD/CAM 1_2011 wishes and their individual requirements (Fig. 1). “Tizian CAD/CAM allows us to machine not only ZrO2 blanks, but also blanks made of wax, composite or PMMA.”Inaddition,Angerisabletohaverestorations produced from gold, non-precious alloys and tita- niumatanyspecialisedmillingcentre. _Simply a matter of greater choice The system’s procedure is easy. A saw-cut model made from plaster is fixed inside the scanner. Then, the customer’s data is entered and an outline scan is carried out. Subsequently, Tizian Scan scans the details. The scanner recognises even complicated geometries after determining separate points. “It takes only eight minutes to scan a three-unit bridge. The scan of a complete jaw takes no longer than 24 minutes, depending on the remaining dentition,” Angerdescribesandadds,“Atthesametime,themodel is displayed on screen so that the user can optionally create fully anatomic crowns and bridges, telescopes and conic crowns, inlays, onlays and veneers or even Maryland bridges and models for the overpressing technique.”Tomakethiseveneasier,Tizianusershave open access to tooth and pontic libraries (Fig. 2). “This way, the desired restoration is created in only a few work steps and the user can adjust the diameters of connectors, the wall thicknesses and the sizes of the cement gaps up to the very last step and determine themindividually,”accordingtoAnger. _Mill at low cost, offer at low cost As all data is created in the universal STL format, Angercansendittospecialisedproductioncentresof hischoice.However,asallTiziancomponentsareex- ceptionally well matched and give Anger the full choice of materials, he mills the restorations at his own laboratory. In addition, he does subcontractor jobsforotherlaboratories.Atthesametime,thepro- duction cost with Tizian Cut is so low that Anger can offerhigh-quality,biocompatibleZrO2 restorationsto his patients at competitive prices. He is even offering a special promotion on uncoloured ZrO2 as a white alternative to silver-coloured non-precious alloy frameworks. The vestibular surfaces of these un- coloured ZrO2 restorations are veneered at such a favourable price that this is fully covered by the pa- tient’s health insurance. Angercanmillbridgesofupto16unitswithTizian Cut and at the same time work economically with regard to raw material, as Tizian Cut uses the blanks optimally (Fig. 3). He has also had success with pin attachments, which he uses in cases in which the prosthetic insertion direction of a prepared stump is so divergent that it cannot be treated using conven- tional restoration techniques (Figs. 4 & 5). The dental technicians at Anger dental laboratory prefer to use ZrO2 for primary crowns in combination with sec- ondarypartsmadefromgalvanicgoldorinconjunc- tionwithimplantabutments. _Fascinating freedom ZrO2 istheperfectmaterialforalmostallformsof dentalrestoration.Itsphysicalandbiologicalproper- tiesaccountforthefactthatthematerialcanbeused almostwithoutlimitindentaltechnology.”TheTizian system offers a great basis for our work and a multi- tude of different scopes for design.“ Anger further states that the system’s easy menu navigation and free choice of all important parameters give him and his colleagues the necessary freedom of design they needanddesire(Fig.6).”Thisfinallygetsusoutofthe one-way street of the dependency of closed sys- tems.“_ Fig. 5_White alternative— Anger offers pure white ZrO2 as an alternative to silver non-precious alloy frameworks and integrates pin attachments in cases of divergent insertion directions.
