Abstract

Resinbased composites are central to contemporary restorative dentistry but remain constrained by polymerization shrinkage, wear and color instability, which compromise longterm restoration success. Nanoenabled resinbased composites (nanocomposites) have been developed to overcome these limitations by incorporating nanosized fillers and engineered nanostructures into conventional resin matrices, thereby enhancing mechanical properties and optical performance. This narrative Review summarises current evidence on the evolution, composition, and mechanisms of nanoenabled resinbased composites; compares their mechanical and aesthetic properties with traditional microhybrid materials; and examines clinical performance, regulatory pathways, and regional market trends with emphasis on India, the Indian subcontinent, Asia, and highincome countries. Nanocomposites generally demonstrate higher flexural strength, superior wear resistance, reduced polymerization shrinkage stress, improved polish retention, and better shade stability compared with many conventional composites, supporting universal use in both anterior and posterior regions. Regulatory authorities such as the US Food and Drug Administration (FDA) have cleared multiple nanoenhanced composites within existing device frameworks, and adoption is increasing globally, although cost and access remain uneven. Future directions include bioactive and “smart” nanocomposites with remineralising and antibacterial functionality, and more robust longterm clinical and healtheconomic data, particularly from low and middleincome settings.
