Assessment of Anterior Teeth Restored With Ultra-translucent Multilayer Zirconia vs Lithium Disilicate Laminate Veneers

October 21, 2020 updated by: Mahmoud abd alkarim ahmed, Cairo University

Clinical Assessment of Anterior Teeth Restored With Ultra-translucent Multilayer Zirconia Versus Lithium Disilicate Laminate Veneers (Randomized Clinical Trial)

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)

Detailed 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
