Cosmetic dentistry does not just mean smile design. The materials and technologies developed for cosmetic dentistry also benefit other procedures in less visible areas. The best cosmetic dentists can only achieve predictable and permanent results by meticulous observation of technique, a thorough understanding of physical, chemical, and biological properties of dental materials, and "discipline." With "discipline" is meant that a dental practitioner should not just know how to establish an optimum operating field, but also do it. There is no way you will have long-lasting and beautiful treatment outcomes, if somewhere along the line a step was omitted, a "corner cut", or a material not properly applied, while observing the bigger picture, i.e. your oral health, facial proportions, and the condition of your TMJ.
Tooth-colored fillings consist of variations of polymethylmethacrylates (PMMA's). They commonly consist of a resin-based oligomer matrix and an inorganic filler such as silicon dioxide. There are large variations in the composition and application of composite materials.The inorganic filler gives it wear resistance and translucency. A coupling agent such as silane is used to enhance the bond between the filler and the matrix. The example above describes the use of one of such composites in combination with bonding agents. Due to the delicate timing of the chemical processes that take place during the procedure, strict adherence to the treatment protocol is necessary.
