Optimisation of Compressive Strength in Zirconia Nanoclusters of the Bis-GMA & TEGDMA based Dental Composites

The aim of this work is to present an analysis of the composites and furnish dentists with a basis that can provide criteria for choosing one or another to suit their therapeutic requirements. Mastication is a dynamic process and tooth is an important component of it. Restoration of lost tooth structure is a challenge to the dentist as well as scientists testing the restorative materials. One of the most commonly used restorative materials is composite resin. The mechanical properties of composite resins are mainly due to its filler content. Dental composites are using silica, quartz and glass as filler for long time. Zirconia is the latest addition as filler. Zirconia is super hard because of the peculiar arrangements of atoms. Mastication is a dynamic situation in which many forces are acting in all possible direction, the most important being the compressive force. We wish to study the contribution of Zirconia as filler in the mechanical properties of the dental composite. Our aim is to optimise the compressive strength in Zirconia nanoclusters of the Bis-GMA & TEGDMA based dental composites. The aim of this paper is to evaluate the important role of Zirconia as filler in the Compressive strength of Dental Composite. Contemporary dental composites are using either one or two fillers individually or in combination. Attempt is made to use Zirconia, glass and silica conglomerate. The optimum composition of hybrid fillers and the optimum compressive strength is obtained.
