Abstract EN
The present investigation was done to measure fracture strength and microleakage of laminate veneers.
Thirty maxillary anterior teeth were selected and divided into three equal groups ( 10 teeth for each design ).
Design {A}; teeth were prepared with feather edge, Design {B}; teeth prepared with 2 mm incisal reduction without palatal chamfer and, Design {C} 2mm incisal reduction with 1mm palatal chamfer .In-ceram laminate veneers were constructed with three different preparation designs and cemented on its corresponding prepared teeth with resin cement, then the tested specimens were thermocycled for 48 hours then the fracture strength was measured using L loyed testing machine at cross-head speed of 0.5 mm/min.
The microleakage were measured using stereomicroscope for fifteen specimens.
The results were statistically analysed using ANOVA and student “t” test.
It was concluded that highest fracture strength was found in design {B} and microleakage was found to be higher in cervical margin than incisal in the three different designs and highest in palatal margin of design {C} than design {A} and design {B} .
