Developed almost half a century ago, dental composites, consisting of a polymeric resin matrix and silanised glass or ceramic fillers, presented opportunities never before equalled in modern dentistry. Compared to dental amalgams, the composites possess better aesthetic property, have fewer safety concerns, and show reasonably satisfactory clinical results. Consequently, the composites have been widely adopted by the dental profession as the restorative material of choice. This book presents research which states that innovative dental composites reinforced with nano-scaled fillers including polyhedral oligomeric silsesquioxane (POSS), fibrillar silicate, and electrospun glass nanofibres were prepared, characterised, and evaluated.
