2 Instructions for use i-motion Zirkon layering ceramic Acc. VITA * classical shade guide colors *VITA is a registered trade mark of the VITA- Zahnfabrik, Bad Säckingen Material and Indication, Contraindication The Audent layering ceramic Zirkon is based on silicate sintered glass ceramic and is colored according to the Vita classical shade guide A1-D4. The Zirkon layering ceramic is only intended for dental applications and for use by trained professionals. A matching transparency and fluorescence allows the reconstruction of natural looking teeth in the form of allceramic crowns or bridges made of tetragonal stabilized zirconia (Y-TZP) with a thermal expansion of K -1 ( C). Contraindications: - Combinations with ceramic materials outside of Audent s described range of product systems and/or material from another manufacturer. - Use of non-approved framework materials. - Sharp edges and corners on the framework or non-anatomically reduced frame shapes. - Dental ceramic and complete ceramic restorations made of glass ceramics are not recommended for patients with bruxism or parafunction. Fabrication of Framework The fabrication of zirconia framework (CAD, CAM, sintering, surface treatment, cleaning) must be performed according to the manufacturer s instructions. The framework must have a reduced anatomical shape and should provide enough space for an even coating of layering ceramic < 2 mm. Sharp edges and corners need to be rounded off. Accurately fitting zirconia framework - 2 -

3 Liner-Bake on zirconia The liners are offered as powder in cans. Mix the required liner with the special liner liquid to a creamy consistency and apply it on the zirconium oxide frame in a thin layer using a brush or glass instrument. Apply i-motion Zirkon Liner 1st Bake After the Dentin application the crown is placed on a firing tray at a starting temperature of 400 C. Subsequently the furnace is closed with a 4 minute closing time and then heated at 45 K/min with vacuum (vacuum starting at 450 C) to 780 C (bake temperature). Hold time: 1 minute without vacuum. For multiple unit prosthesis with bigger amount of porcelain increase the firing temperature about C. After the first Dentin/Incisal firing is complete, trim the crown or bridge and clean. Next, apply a second layer of Dentin and Incisal for the second Dentin firing. Burnt i-motion Zirkon Liner 2nd Bake Same procedure as by the first Dentin firing, except with a firing temperature of about 10 C lower than the previous bake

4 Margin-Bake on zirconia Apply a thin layer of Margin separator liquid to the shoulder of the die. Mix the margin powder with margin liquid to a creamy consistency. Apply margin shoulder ceramic mix in small portions and condense by tapping, suction any excess liquid and dry well. 1st Bake After the margin application, the crown or bridge is placed on a firing tray at a starting temperature of 400 C. Subsequently the furnace is closed with a 4 minute closing time and then heated at a rate of 45 K/min with vacuum (vacuum starting at 450 C) to 840 C (bake temperature). Hold time: 1 minute without vacuum. After the first bake, place the crown on the die and remove excess materials. A second margin application follows where necessary to optimize the fit. 2nd Bake See first Bake (830 C). Dentin-Bake on zirconia Mix ceramic powder (Dentin and/or Incisal) with modelling liquid to a creamy consistency. Apply Dentin or Incisal ceramic in small portions to the cervical and interdental area and compact by light vibration. Then more Dentin or Incisal is applied according to the tooth layering. Layering with i-motion zirtan Dentin And/or Incisal Drying before 1st bake - 4 -

5 1st Bake After the Dentin application the crown is placed on a firing tray at a starting temperature of 400 C. Subsequently the furnace is closed with a 4 minute closing time and then heated at 45 K/min with vacuum (vacuum starting at 450 C) to 780 C (bake temperature). Hold time: 1 minute without vacuum. For multiple unit prosthesis with bigger amount of porcelain increase the firing temperature about C. After the first Dentin/Incisal firing is complete, trim the crown or bridge and clean. Result after 1st bake 2nd Bake Next, apply a second layer of Dentin and Incisal for the second Dentin firing. Corrections before 2nd bake Corrections before 2nd bake Same procedure as by the first Dentin firing, except with a firing temperature of about 10 C lower than the previous bake.. Result after 2nd bake - 5 -

6 Glaze finish/glaze Bake on zirconia After completely finishing the surface with a diamond instrument, thoroughly clean the crown or bridge. Glaze bake of layered crowns and bridges without glaze ZT, stains ZT or shades ZT application is carried out at temperatures of about 740 C 760 C. Apply the glaze ZT paste or powder and liquid mix in thin layers. For the color characterization, all Audent stains ZT or shades ZT and glaze ZT can be applied and fired. Applying fluorescent stains/shades Bake After the glaze application, place the crown on a firing tray at a starting temperature of 400 C. Subsequently close the furnace with a 4 minute closing time and then heat at a rate of 55 K/min without vacuum to 750 C (bake temperature). Hold time: 1 minute without vacuum. For full-contour crowns and bridges made of Y-TZP the firing temperature may be increased up to 800 C, depending on the desired surface aspect. Restoration after bake Finished restoration - 6 -

7 Integrated Restoration Integrated restoration in patient mouth Clincal Case Work and documentation: Zahntechnisches Labor Franz H. Müller Anstalt Austrasse 13 Postfach Vaduz FL Principality of Liechtenstein Dr.med.dent. Kathrin Heidegger Müller Staatsexamen der Zahnmedizin, Universität Basel Erlangen der Doktorwürde, Universität Basel Zahnärztin, Praxis f. allg. Zahnheilkunde Franz H. Müller Vaduz Martin Grossberger ZTM (CMDT) Meisterschule/Meisterprüfung Freiburg i.br. Productmanager veneering materials ((Ivoclar) Technische Leitung Labor Franz H. Müller, Vaduz Conclusion i-motion zirconia veneering ceramic satisfy through its excellent stability during layering and modellation. The fine grained material is very good in handling and will result in an ideal baking result.a esthetic and precise shade reproduction of the natural teeth is easy to achieve with i-motion zirconia

8 Combinations and Firing table Note: The given firing temperatures were determined in a Zubler Vario 300 dental furnace and are approximate values. For other furnace types, corrections to the firing temperatures may be necessary. Firing data is in the firing table and possible material combinations are mentioned in the combination table below.

More units require up to C higher firing temperature. Please note: in case of layering on zirconia retarded opening of the furnace after each bake, beginning with Margin-Bake is required in general, especially in case of voluminous layering ceramic! - 8 -
