As one of the most common dental filling materials, composites have been widely used in clinical application for nearly 50 years. There are many types of composite products available for clinical use by several different classification systems. However, challenges facing dental composites were: restoration fractures, secondary caries, biodegradation, and technique sensitivity. The growing interest in nanotechnology and its use in resin composites was based on the desire to utilize the ability of nanosized particles to alter the structure of the composite. This in turn may improve mechanical, chemical, and optical properties and develop a resin composite that can perform optimally in all parts of the mouth. Several nanotechnology-based strategies were developed to overcome composite challenges; were whether changes in fillers size and loading, self-healing composite, smart composite, degradation resistance matrix, bulk fill composite, self-adhesive composite, and universal shade composite. |
