Method and system for production of anti-microbial orthodontic elastomeric ligatures

Abstract

A method for production of anti-microbial orthodontic elastomeric ligatures is disclosed. The elastomeric ligatures are coated with an anti-microbial solution layer by layer. The coating solution comprising an anti-bacterial agent, a polymer and a solvent in the following ratio: 2 g anti-microbial agent, 4 g polymer and 200 mL solvent. The hypo-allergic latex-free orthodontic elastomeric ligatures with an internal diameter of 0.045 inches and external diameter of 0.115 inches are rinsed in distilled water, dried at 60° C. and sprayed with the anti-bacterial solution two times and dried for five minute. This process is repeated for five times and the elastomeric ligatures are dried at room temperature for 1 h.
