3M™ Lava™ Esthetic Zirconia

 

The first zirconia to offer inherent fluorescence features built-in color technology for the best shade matching in any light. A high level of translucency and a flexural strength of 800 MPa combine in this revolutionary material to provide astounding natural esthetics in a durable restoration.

Indications: Lava™ Esthetic zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges, Maryland type bridges and screw retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.
Contra-indications: When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics
Preparation: Shoulder preparation not needed. A mild champfer or a feather edge margin is good. 1mm buccal, lingual and occlusal reduction is ideal, but can go to .8mm in some areas, when reduction is limited. Minimum occlusal reduction of 0.8 mm; 1 mm is ideal.

Adjustments and polishing: Adjust Lava™ Esthetic zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid micro-fractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces. Polish Lava™ Esthetic zirconia restorations with the porcelain polishing system of your choice.
Tech Notes: Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
