Introduction

Over the years, methacrylic polymer materials are widely used in the production of active and passive removable orthodontic appliance. These removable orthodontic Appliance orthodontic treatment mainly for children. There are some potential problems with the production method of orthodontic appliance polymer part by polymerizing Process and polymer/monomer ratio impact, removable orthodontic appliance of the polymer portion of the performance to be worse than the use of traditional boxing heating Aggregation made of denture base polymer. Compared with the heat-curable denture base polymer materials, orthodontic appliance residual monomer content And other impurities more and more dangerous. In addition, high monomer content of the polymer/monomer ratio may result in increased shrinkage of the polymer. ISO 20795 does not include qualitative and quantitative requirements for biological hazards, but it is strongly recommended to assess possible biological or When toxicological hazards, referring to GB/T 16886 and YY/T 0268. Dentistry denture base polymer Part 2. Orthodontic denture base polymer
