Physical and mechanical evaluation at a new polymeric coating varnish to fixed dentures and improvement of bonding method in the system metal-polymer

Abstract

Since the beginning of polymers using for aesthetic facing fixed dentures, the main problem was creation secure fastening of facing material to metal framework surface. For many years, scientists have solved many issues such as: improvement of synthetic materials, equipment, mechanical retention to metal framework, chips facing restoration in the mouth and so on. Contemporary acrylic polymers have high physical, mechanical and technological properties, allowing to reduce the rate of complications in orthopedic treatment with combined fixed dentures. But it remains the basic condition – the creation of facing material secure fastening to metal frameworks surface, this adhesive bonding may be reproduced with mechanical, physical or chemical principle, but usually it is combination of these types of bonds
