Nanotechnology in Dentistry: From Fiction to Reality Nanotechnology has garnered significant attention across various professions and industries and is now becoming more integrated in dentistry. This innovative technology, which involves the manipulation of matter on an atomic, molecular, and supramolecular scale, holds great potential for the future of dental care. Dr. Normand Bach, associate professor in orthodontics at the University of Montreal, provides an overview of how this technology is being integrated into dental practices, particularly within orthodontics. Nanotechnology refers to the branch of science and engineering devoted to designing, producing, and using structures, devices and systems by manipulating atoms and molecules at nanoscale. In the context of dentistry, nanotechnology has been described as the “synthesis of bioactive materials,” says Dr. Bach. These materials include glass ionomers, composite resins, and other biocompatible products that are engineered to release various ions, such as calcium and phosphorus, when used intraorally. According to Dr. Bach, nanotechnology’s potential uses in dentistry include remineralization, preventing demineralization, and antibacterial properties of nanoparticles. “Many applications can be used with this new generation of materials currently being synthesized and researched at the moment,” he says. Restorative materials are benefiting from the advancements in nanotechnology. Traditional dental restorations degrade over time due to wear, shrinkage, and bacterial infiltration. Nanotechnology can improve materials on a molecular scale. “Adding specific nanoparticles to certain restorative materials and adhesive systems may enhance their mechanical and physical properties like reducing polymerization shrinkage,” explains Dr. Bach. These improvements should result in more durable and esthetically pleasing restorations.
