Details and patient eligibility

About

A Minimally invasive esthetic restorative approach with the advancement of highly translucent multilayered monolithic zirconia ceramic can provide minimal thickness that affords high strength and esthetics without the need for layering porcelain. The effect of sintering conditions on yttria-partially stabilized zirconia is essential for the long-term success of such restorations.

The study aims to evaluate the clinical performance of speed and conventional sintering on ultra-thin, highly translucent, multilayered zirconia laminate restorations with minimum invasive tooth preparation.
