Abstract:

PMMA, the most largely used material in acrylic denture fabrication, has many favorable characteristics, but also several disadvantages, regarding its physical, chemical, biological and mechanical properties. Extensive research has been done, in order to improve PMMA mechanical properties, by changes in the chemical structure, material reinforcement using fibers or fillers of different types, sizes, shapes, in different concentrations, or by obtaining hybrid materials. Progress in nanosciences and nanotechnologies led to the development of new nanomaterials with properties different from those of the original material, while their use, like additives for example, can improve the characteristics of the obtained materials. The area of nanosciences, yet insufficiently explored, opens new perspectives and possibilities in dentistry, dental materials and many other domains.
