Clinical Trial Summary

The aim of the present study is to assess the clinical performance of multilayered translucent zirconia laminate veneers versus lithium disilicate laminate veneers in terms of modified USPHS criteria for assessment of dental restorations (retention, restoration integrity, color match and marginal adaptation)

Description:

inferior mechanical properties of glass ceramics necessities the continuous development and modification for materials suitable for all clinical situations

multilayered translucent zirconia provides the advantages of high mechanical properties than all glass ceramic in addition to the improved translucency in the new generations.

Therefore, the purpose of the present study is to evaluate the clinical performance of newly introduced multilayered translucent zirconia as a monolithic laminate veneer in comparison with lithium disilicate laminate veneer to determine the clinical functional and structural integrity of the restoration
