Biomimesis, a bioengineering concept that means mimicking natural biologic essence, is the key factor of all healers in restoring lost natural substance.
As dentists, today more than ever, we have the ability to repair, replace, and restore lost natural structure in such a way that biologic form, function, and appearance are restored, as well as masking the fact that there ever was a defect.
Direct composite resin systems provide ultraconservative, long-lasting solutions to many dental aesthetic problems.1 Success with composite resin restorations depends on the combination of 3 factors: material selection, the type of adhesion used, and placement technique.2 Simplification and speed are emphasized with most of the newer materials and the equipment available today.
Research has now produced self-adhering restorative composite resin systems that successfully bond to tooth structure, and that has eliminated the need for the separate use of etchants or bonding agents. Collectively, this category of self-adhering, light-cured, resin-based composite dental restoratives are designed for direct placement. They are indicated for all cavity classes in the anterior and posterior teeth alike. They have incorporated adhesion technology, which eliminates the additional steps of etching/priming/bonding otherwise necessary to bond a resin composite to dentin and enamel.
Other systems, like the nanofilled composites, produce all of the positive characteristics of the microfilled resins, including polishing and handling, along with the better physical properties of the microhybrid systems. The formulations of these composites have been designed to combine dentin color and enamel value in relationship to the natural tissue anatomy. These composite restorative systems not only simplify the replication of the optical properties of the natural tooth, but have similar physical and mechanical properties to that of tooth structure and can easily be combined with the self-adhesive systems for sensitivity elimination. Therefore, composite resins have become simpler to use. The resin systems that have been available to dentists for more than 40 years now are not the same anymore.
