Composites - Essay Examplel made by combining two or more distinct materials in order to fabricate a new product bearing sexually attractive combination of properties that a single materials cannot achieve (Noort & Barbour, 2013). These materials range from polymer, metallic to ceramic elements (Naseem, 2010). Dental composites are bump resistant including composite resins, glass monomer cement, compomers and giomersFor this case, I will design a composite that meant to replace amalgam as filler in dentistry. The composite moldiness have a pH change as well as the ability to form a carboxylate salt. The material also has to contain fluoro-aluminosilicate glass, piddle as well as a polymeric acid (Brantley, & Eliades, 2011). In addition, the material ought to have amend physical conditions compared to conventional glass ionomoer. Such improvements aid reduction in water sensitivity, less fluoride release, reversible fluoride besides increase in thermal expansion (Naseem, 2010). Most importantly, the material has to be light corned to achieve good bonding to dentine, which depends on surface conditioning (Brantley & Eliades, 2011).The composite used should be anisotropic since forces from different directions act on them.The forces acting on the other direction enhance materials properties in nonpareil direction (Brantley, & Eliades, 2011). Properties of strengths and stiffness depend on the direction of force applied. Transverse direction will be necessary for the composite because elastic constants are similar (Brantley, &Eliades, 2011).Physical properties of the material needed for matrix involve low solubility, high compressive strengths, as well as low flexural and sheer strengths. In addition, the material must have a thermal coefficient similar to dentin besides fluoride release and fluoride recharge. Glass monomer cement binds tooth and has various(a) dimensions such as slight shrinking and expansion when setting (Naseem, 2010). It is also britt le and lacks translucency characterized by a rough
