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.
Celtra Duo is a lithium silicate, glass-ceramic restoration. Indicated for single unit crowns, 3 unit anterior bridges, inlay/onlay and veneers.
Bridges which include molars, Maryland style bridges, and bridges which have a short vertical height that does not allow for adequate connector height.
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.
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.
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.).
