Prosthodontics is the discipline of dentistry which emphasizes dental prostheses. It is generally for dental imperfections, tooth loss therapy such as crowns, and dentures. It also includes the utilization of imitated prostheses for periodontal disease. The foremost rationale of denture is to reinstate function of teeth and facial manifestation. Three varieties of dental materials are used, viz., resin, ceramic, and metal. As dentures are in direct contact with the oral mucosa, these materials must possess efficient biological properties with certain mechanical strength and hardness with low shrinkage deformation.
They are important to fabricate dental prosthesis, which directly contacts with the oral mucosa and is under long-term use in the oral environment, so the dental materials must have comprehensive properties and good biological activity to function properly. Dental materials should have certain mechanical strength, hardness, higher fatigue strength, high elastic modulus, low thermal and electrical conductivity, good castability, and less shrinkage deformation. Chemical stability is also required, such as corrosion resistance, being not easily broken, and aging. The colors of dental materials can be formulated and maintain long-term stability. As a good oral material, it should have good biocompatibility and safety and be biofunctional.
Nanomaterials can be divided into four categories of nanopowder, nanofiber, nanomembrane, and nanoblock, in which development of nanopowder is longest, and its technology is most mature. Nanomaterials have small size, large surface area, high surface energy, a large proportion of surface atoms, and four unique effects: small size effect, quantum size effect, quantum tunneling effect, and surface effect. Development of nanomaterials has greatly enriched the field of research in materials science including biomaterials. As people's understanding of natural biological material properties and microstructure at nanoscale is gradually deepening, the role of nanomaterials in biomedical material science is more important.
