In order to preserve health dental tissue as much as possible demand for non-invasive procedures increased over the last decade. In response to that use of porcelain veneers has become a common approach to treat worn, misaligned, fractured, discolored and malformed teeth. Furthermore, the clinical indications for such restorations have been progressively increased due to the development of new ceramic materials. With these new materials, we can achieve a greater reduction in thickness of final restoration and effective bonding to enamel, which directly affects the preservation of health dental tissue in harmony with the principles of minimally invasive dentistry. Porcelain veneers and porcelain no prep veneers offer the amazing smile makeover results, but the composition of, preparation for, and application of both these cosmetic restorations have some differences. It is difficult to compare these two types of restoration but we will try to compare the differences between them and the cases when they are really indicated.
