INfuse™ Glass Ceramic

INfuse™ Glass Ceramic

This innovative restoration is fabricated out of a zirconia-reinforced lithium silicate and offers a wide variety of advantages over its restorative counterparts. INfuse™ Glass Ceramic offers exceptional strength and esthetics that matches and exceeds its alternatives fabricated out of lithium disilicate. INfuse™ has a flexural strength of more than 500 MPa. Zirconia-reinforced lithium silicate is carefully formulated to balance translucency and opalescence, which ensure lifelike beauty for every restoration. This all-ceramic option matches all 16 VITA® Classical Shades and an attractive chameleon effect for in-vivo blending.

Indications

Celtra Duo is a lithium silicate, glass-ceramic restoration. Indicated for single unit crowns, 3 unit anterior bridges, inlay/onlay and veneers.

Contraindications

Bridges which include molars, Maryland style bridges, and bridges which have a short vertical height that does not allow for adequate connector height.

Preparation

Anterior full-coverage crowns require a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Facial reduction is 1.5 – 2 mm; 1 – 1.5 mm lingual contact clearance. Incisal reduction is 1.5 – 2 mm with rounded internal line angles, and an incisal edge at least 1mm wide to permit optimum milling of the incisal edge during CAD/CAM processing. Posterior full-coverage crown requires a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Occlusal reduction is 1.5 – 2 mm: axial reduction (buccal, lingual, and interproximal) is 1.5 mm with rounded internal line angles.

Cementation

Celtra duo can be cemented using a resin reinforced glass ionimer such as RelyX Luting cement. Or bonded using a resin cement when extra strength is needed due to lack of retention on the prep, use a resin cement such as RelyX Unicem or RelyX Ultimate.

Tech Notes

If adjustments are needed, use fine diamonds with water and light pressure. Always remove the crown when adjusting or bond/cement crown before adjustments are made.).
