Due to an increasing interest in Esthetics, Patients and Dentists have been looking for Metal-Free

tooth-coloured Restorations.

Porcelain chiP off

Marginal discolouration

Whats wrong with our conventional PFM Crown&bridges??

Increased opacity

The development of new high Strength dental ceramics,has dominated &are highly attractive in prosthetic dentistry, where strength and esthetics are Paramount..

ALL CERAMIC RESTORATION.

• ALUMINA

• ZIRCONIA

What is Zirconia?

• Zirconia is a crystalline dioxide of zirconium.

Zirconium (ZrSiO4) belongs to the mineral group of silicates and was discovered in 1789 by the German chemist M. H. Klaproth.

Currently available zirconia-containing ceramicsystems are :

•yttrium cation-doped tetragonal zirconia polycrystals (3Y-TZP),

•magnesium cation-doped partially stabilized zirconia (Mg-PSZ) and

•Zirconia toughened alumina (ZTA).

Why Zirconia is superior??

• Adhesive luting – Resin cements with MDP primer .

• Sand blasting

• Silane coating

TAKE HOME MESSAGE..

• Zirconia+porcelain Veeneering –Anterior tooth replacement

• Full contour Zirconia –posterior tooth replacement

• Resin cement-excellent adhesion properties

RESTORE ESTHETICS NATURALLY…
