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.

RECRUITINGChange in clinical performance
Patients will be recalled every 3 months for one year follow up. The clinical evaluation and color measurement will be based on the modified California Dental Association (CDA)/Ryge criteria of evaluation as shown Examiners will evaluate the zirconia Veneers for the following: 1. Color match. 2. Zirconia surface. 3. Marginal discoloration. 4. Marginal integrity. 5. Clinical evaluation of the completed restorations will be performed using a double-blind assessment method
Time frame: Baseline, 3 months, 6 months, 9 months, 12 months
