Anterior Tooth 0.6MM Ceramic Veneer IPS. E.MAX Ceram Good
1.The thikness is 0.6 mm.
5.abrasion resistance and tissue compatibility.
6.chemically verystable and have a coefficient of expansion similar
to that of enamel.
More security firm, because adhesive technology is advanced,
7. improved aesthetics can be achieved with minimal tooth
reduction, and the palatal surface of the tooth is unchanged so
that incisal guidance is maintained.
♦ Normally restore aesthetics for anterior teeth.
♦ Enamel hypoplasia, tetracycline teeth, dental fluorosis,
deformity teeth, tooth clearance is too large, the decay and cut
side defect, etc.
