4 Lava Zirconia A Broad Range of Indications Single Crown Tall Crown Splinted Crowns 1 3-unit Bridges 4-unit Bridges 5-unit Bridges 2 6-unit Bridges 2 Curved and long-span Bridges 2 (With the release of Lava Frame Multi XL) Cantilever Bridges 3 (excluded for patients with bruxism) Inlay & Onlay Bridges 3 (excluded for patients with bruxism) Anterior Adhesive Bridges 4 (excluded for patients with bruxism) Primary Crowns/Telescopes Lava Zirconia build-up for two-piece abutments Lava All Zirconia

5 Lava All Zirconia Lava Zirconia in occlusal contact for full flexibility From monolithic Lava All Zirconia restorations over partially to fully veneered restorations Cover all your esthetic and strength needs with Lava Zirconia!

6 Lava All Zirconia Your tooth-colored, biocompatible solution for challenging clinical cases Replace full-cast metal and metal occlusal restorations in cases with little inter-occlusal space for bruxists and grinders

9 Lava Zirconia - Patented Shading System Homogenous shading by optimized diffusion Maximized translucency even when shaded Shaded Lava Zirconia Competitor

10 Esthetics - Shading Lava All Zirconia restorations are available in different Shades according to Vita Classic Monochrome Shading Custom Shading

11 Esthetics Finishing Polish Individualization by Stains and Glaze Partial Veneering Stain and Glaze

12 Full flexibility Now you can cover all your strength and esthetic needs with Lava precision! Fully Veneered Lava DVS Partial Veneer with Zirconia Occlusal Partial Veneer on buccal Monolithic Lava All Zirconia

13 Esthetic Requirements Inter-occlusal Space and Esthetic Demands influence the degree of Veneering Framework with porcelain veneer NEW: Lava Zirconia stops (contact points on Zirconia) on porcelain veneered restoration NEW: Lava Zirconia occlusal with partial porcelain veneer (e.g. on buccal side of a premolar) NEW: Lava Zirconia without porcelain veneer Best esthetics Cases where top esthetics is demanded but there is limited occlusal space Cases with limited occlusal space but with demand for high esthetic Replacement of full metal or metal-occlusal PFM s for Bruxers or limited space or low cost cases

33 Bottom Line of In-vitro Wear Data Antagonist wear directly correlates to material smoothness Polished Lava Zirconia is wear resistant and stays smooth under wear - even after accelerated aging by autoclaving Polished Lava Zirconia is more gentle to the antagonist than state-ofthe-art veneering porcelains Under high wear loads polished Lava Zirconia is more gentle to the antagonist than lithium disilicate material Glazed Lava Zirconia behaves similar to state-of-the-art veneering porcelains in terms of wear

38 The messages to spread about Lava All Zirconia Polished Lava All Zirconia exhibits less wear at the antagonist than present State-of-the-Art veneered ceramic surfaces. Lava All Zirconia is especially suited in clinical cases with only little inter-occlusal space or bruxists. Lava All Zirconia delivers adequate esthetics for posterior restorations and expands your flexibility to cover special strength needs.
