Study Details

Study Description

Brief 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)

Condition or Disease	Intervention/Treatment	Phase
Retention, Color Match, Marginal Adaptation and Restoration Integrity	Procedure: Ultra-translucent multilayer zirconia; Procedure: Lithium disilicate	N/A

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

   assessment of restoration will be done for restoration integrity on the base of of modified USPHS criteria for assessment of dental restorations

Other Outcome Measures

1. Color match [12 months follow up period]

   assessment of restoration will be done for color match on the base of of modified USPHS criteria for assessment of dental restorations

2. Marginal adaptation [12 months follow up period]

   assessment of restoration will be done for Marginal adaptation on the base of of modified USPHS criteria for assessment of dental restorations
