Abstract

Correction 11/11/2016 This invention involves the production of Self-Cured Orthodontic Poly-Methyl-Methacrylate PMMA Powder for use in orthodontic applications. Tacylate monomer deionized water Reactant And a stabilizer and where there is a production process with the introduction of methyl - methacrylate monomer to distill and dissolve Initiate a chemical reaction in methyl-methaclicate. Refined monomer And dissolve the stabilizer Into deionized water. The two parts of the resulting substance are mixed together in a stirrer. The polymer that has been washed with water and dried. A clear, self-curing acrylic resin powder is obtained. It is molded into teeth and has mechanical and physical properties that can be accepted in a clinic setting ------------------------- This involves the manufacture of self-cured orthodontic poly-methyl-methacrylate (PMMA powder) acrylic resin powder for use in orthodontic applications with Transparency by means of suspension polymerization To obtain resin particles between 10-1000 microns in size that can be molded into teeth and have mechanical properties as well as physical properties. Body that can be accepted in a clinic:
