Veneers are ceramic shells specially made for front teeth. These porcelain facets are very thin (about 0.5 mm), are glued over the tooth, matching the tooth color, they could be transparent, or opalescent to mask any undesirable natural tooth color. Veneer ceramics have positive qualities related to tension, resistance to chewing pressure and most importantly biocompatibility with the surrounding soft tissues.
The most common indications for veneers are:
- Broken teeth
- Unaesthetic fillings
- Dark (tetracycline) teeth
- Gaps between the front teeth
- Teeth with uneven size or malposition
Compared with regular teeth crowns, the use of laminates is very modest to dental tissues, because less tooth structure must be prepared, only about 0.5-0.8 mm.
Preserving flawless white teeth is not easy. Coffee, tea, nicotine, red wine and certain foods lead to a rapid staining of the teeth. The cure for it is a professional whitening done by modern methods, which leads to prolonged illumination color of teeth. The unwanted initial discoloration of the teeth caused solely by dental plaque, must be removed before starting the treatment.
While toothpastes with whitening features have only a temporary effect, professionally used concentrations of hydrogen peroxide or carbamide peroxide, reach the inside of the tooth and leave longterm effect on the color. They act on dentin level pigments, which are responsible for unwanted discoloration, and largely neutralized.

METAL- FREE CROWNS
Zirkoniumdioxide is an excellent material for metal-free restorations because of its biocompatibility, strength and durability. The feature of semi-translucency of the zirconium gives the possibility to reconcile the dentin, the cervical and the enamel colors with opaque colors, so these are decisive factors for ideal aesthetics of these crowns in any circumstances.
Metal-free ceramic today is a standard material for aesthetic reconstructions on natural teeth and implants in the form of veneers or laminates, metal-free ceramic crowns, ceramic bridges, inlays and onlays ceramic crowns and zirconium abutments over implants.
Due to the fact that metal- ceramic crowns and bridges have limited aesthetic characteristics with the occurrence of the gray edge in time, sometimes no vivid color, and possible allergy to metal, they are now slowly going into history.
Transparent ceramics enable the translucency of the natural tooth substance color and in reverse allow light to pass through ceramics to natural tooth. Prosthetic restorations made of this kind of material obtained optical properties similar to natural teeth. Designing the zirconium construction with CAD / CAM gives accurate fit in less than 100 microns.
