GC Initial™ LiSi
This high-strength lithium disilicate solution offers superior esthetics and strength. It utilizes proprietary HDM (High Density Micronization) technology from GC America that equally distributes micro-crystals throughout the entire glass matrix. This dispersion ensures excellent physical properties, unlike its alternatives which utilize traditional larger-sized crystals.
- Biaxial Flexural Strength >500 MPa
- High Density Micronization Technology
- High Esthetics
GC Initial™ LiSi is the premium lithium disilicate, glass-ceramic restoration. Combining lifelike materials and fracture resistant properties, GC Initial™ LiSi is as durable as it is lifelike. The flexibility of GC Initial™ LiSi makes it an excellent restorative method for anterior esthetics or posterior function.
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.
GC Initial™ LiSi – 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.
