Metal-free veneers represent the XXI. century's technology in dentistry and they fulfill the highest aesthetic requirements. Instead of metal we make the coverages, crowns and the bases of the bridges from aluminium-oxide or zirconium-oxide ceramic, which is tooth-colored, that's why it is maximally aesthetic.
Beside the high aesthetic outlook they are ultrapunctual, that's why they have a long lifespand and they don't cause allergy. The Zirconium frame are so strong that even bridges can be made from them.
