Aim: The aim of this study was to evaluate the effect of convergence angle 12{u00B0} and 18{u00B0} of tooth preparation on the internal fit and marginal accuracy of hybrid Enamic restoration . Results: Irrespective of occlusal taper angle, totally it was found that PFM group recorded statistically non-significant (P>0.05) higher vertical marginal gap mean value (53.66± 6.59æm) than Enamic group which recorded vertical marginal gap mean value (51.95 ±5.98 æm) as indicated by two wayANOVA followed by pair-wise Tukey's post-hoc tests. Conclusions: The vertical marginal gap of hybrid ceramic improved with increasing the convergence angle of the preparation to 18{u00B0}. The vertical marginal gap of PFM showed better result with decreasing convergence angle of the preparation to 12{u00B0}.
