Систематический обзор: анализ цитотоксичности базисных материалов

Basic materials dentures can cause chemical irritation and allergic reactions when communicating with theoral cavity. The overview shows that all the polymers of acrylic origin exhibit cytotoxicity in varying degrees, regardless of the type of polymerization, although with some degree of reliability can be mentioned lower cytotoxicity thermoset materials in comparison with other type ofactivated polymers. Use in the manufacture ofprostheses solid lining materials leads to increased cytotoxicity. This leads us to the conclusion that reducing the side effects ofPMMA prostheses necessary to search for new ways to restrict the inflow discharge of substances into the oral cavity. The perspective in this case is the development ofprotective coatings. Among those highlights we have developed recently a coating of silicon carbide "Shell”, which in addition to barrier properties relative to the leaching of substances from acrylic plastic a number of additional benefits: high chemical inertness and resistance to biodegradation, homogeneity, durability, mechanical strength and good adhesion to a range of materials at high temperatures.
