In-Ceram® Crowns
In-Ceram® Spinell offers exceptional translucency and 350 MPa of strength for single anteriors, inlays, onlays and veneers.
In-Ceram® Alumina is perfect when a high degree of translucency is required along with a higher strength (500 MPa), as in single posterior crowns.
Both achieve natural three-dimensional color, translucency and vitality.
All layering and shading from within restoration as in natural dentition.
Negligible sintering shrinkage allows marginal fit of 20-25 microns.
Provides excellent gingival response, eliminating irritation and unsightly gum recession.

The first all-ceramic materials certainly offered improved esthetics when compared to conventional metal-ceramic restorations. Unfortunately, they also had inadequate physical properties which hampered their long-term clinical success. Glass ceramic materials, with a higher crystalline content, more even distribution of crystalline reinforcement and smaller crystal size resulted in higher strength and better physical properties. Unfortunately, these systems also had an inherent weakness. Glass is a naturally brittle material that allows fracturing through crack propagation at low critical strains.

Introduced by Vita in 1989, In-Ceram® Alumina signaled the beginning of a new era in esthetic all-ceramic restorations. The reinforcing component utilized with In-Ceram® formed a continuous sintered skeleton-like meshwork. This core meshwork was then infiltrated with a low viscosity lanthanum glass at a high temperature. Crack growth was all but eliminated.

In 1994, the system expanded with the introduction of In-Ceram® Spinell (a mixture of magnesia and alumina) - a framework material with increased translucency for anterior crowns, inlays, onlays and veneers. Both Alumina and Spinell are three to four times stronger than prior dental ceramics. Each results in different properties. The Alumina cores are stronger, but less translucent, than Spinell cores. Therefore, the Alumina cores are recommended for anterior and posterior crowns and anterior 3-unit fixed bridges. The Spinell cores are only recommended for anterior crowns.

All In-Ceram® system crowns and bridges allow you to provide an optimal shade match with Vitadur Alpha veneering porcelain in the new Vitapan® 3D-Master™ Shades as well as Vita Classical (previously called Lumin Vacuum) shades. Unlike manufactured copings, In-Ceram® is easy to adjust prior to glass infiltration, giving the technician complete control. Doctors can use their preferred luting method since the strength of In-Ceram® makes it compatible with conventional zinc phosphate as well as glass ionomer and composite adhesives.

The In-Ceram® system now offers an all-ceramic solution for every indication. Doctors can tailor their all-ceramic restorations to the esthetic need of their patients. Spinell offers exceptional translucency and 350 MPa of strength for single anteriors, inlays, onlays and veneers. Alumina is perfect when a high degree of translucency is required along with a higher strength (500 MPa), as in single posterior crowns.
