%X Loss of anterior tooth causes aesthetic and functional disharmony. Although no restorative material can approach the appearance of intact tooth enamel, glass ceramic, at the increased risk of brittle fracture, can mimic original tooth color better than the other restorative options. The newest zirconia material comes with unparalleled individualization in aesthetics and optimal physical properties. One of the basic principles of tooth preparation is conservation of tooth structure. This clinical report describes the replacement of maxillary and mandibular incisor with latest generation zirconia adhesive fixed partial denture. The authors have achieved unmatched aesthetics with newer high translucency zirconia. 1. Article Proper In the field of indirect restorative materials, it has always been desirable to have the right blend of aesthetics and durability. The zirconia material conquers all domains of dental restorations where extreme precision, strength, and aesthetics are required. The recently introduced high performance zirconia adds to its appearance by having improved translucency, that is, although inferior to glass ceramic but of course without as much as two thirds reduction in flexure strength. With respect to dental restoration, aesthetics means color that is matched perfectly in lightness to its adjacent teeth and translucency. Translucency refers to having the appearance between complete opacity and complete transparency. In order to produce lifelike restoration, the light must be transmitted and reflected as it does with the natural tooth and it¡¯s done. Lava plus high translucency zirconia is recently introduced by 3M ESPE (3M ESPE, St Paul, MN). It is an after comer of original Lava zirconia, which is considered as one of the most successful ceramic systems. The newer version can be fabricated with hand layered, pressed, or monolithic options. This material is available with the widest range of dyeing liquids and Lava plus effect shades for excellent color match with VITA classical shade guide and unprecedented customization. It is claimed to have the only zirconia system with direct conversion to VITA system 3D-MASTER shades. The translucency of zirconia material is determined by impurities and structural defects as it causes light absorption and scattering, respectively. The high quality processing of Lava plus minimizes the effects of impurities and structural defects. The translucency of zirconia material is reduced by different refractory index and segregation nature of the alumina which is added into zirconia for aging stability. In
