This randomized clinical study aims to evaluate the clinical performance and occlusal wear resistance of nano-zirconia reinforced glass ionomer restorations in comparison to Nano-hybrid resin composite in proximal cavities.
Statement of the problem: The glass ionomer restorations have a wide use in dental community. Proximal restoration is a challenge, due to the high forces present in this area that require more high fracture resistance restoration material which is not obtained in the most of the versions of glass ionomer restorations that are available in dental market.(Safy, 2019) Rationale for choice of intervention: Zirconomer improved, is a nano zirconia reinforced glass ionomer, which has improved the mechanical, esthetic and handling properties than its previous successor, zirconomer. Zirconomer is commercialized as a white amalgam as it features mechanical properties similar to amalgam restorations. In this generation also, translucency is improved to be similar to the tooth structure.(Shetty et al, 2017) As Zirconomer improved is reinforced material, it is expected that has high wear resistance than the conventional glass ionomer restorations.
