Patients that suffer from allergic reactions to common dental materials have been using Valplast® restorations for more than fifty years with an amazingly low reaction rate. Valplast® is a thermoplastic nylon which contains no acrylic monomer and a completely metal free colouring agent, making it an excellent choice for patients who suffer allergic reactions to acrylic and metal dental materials. You contact RDT Technology Ltd on 01903 700037 if you would like a sample chip of Valplast® resin to test for reactivity.
