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 lmm palata chamfer .In-ceram laminate veneers were constructed with three different preparation design and cemented on its corresponding prepared teeth with resin cement,then the tested specimens were thermocylced for 48 hours then the frilcture strength was . measured using L loyed testing machine at cross-head speed of 0.5 mm/min. The microleakage were measured usinf stereomicroscope for fifteen specimens.The result were statistically analysed ysing ANOVA and "t" test.It was concluded that highest fracture strength was found 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 esign {C} than design {A} and Design{B}The present investigation was doneto measure fracture strength and microleakag of laminate veneers.
