Abstract: Three adhesives formulated with Trimethylolpropane Trimethacrylate (TMPTMA) that do not contain BisGMA were developed, whereby the mutagenic and teratogenic risk by the release of bisphenol A is eliminated, and presented a better performance compared to the three commercial adhesives prepared with BisGMA (Adhesive A, Adhesive C and Adhesive B). The invention provides an adhesive used in one-step and provides a system which is formed by a primer and a slurry. The adhesives of the invention were compared with two commercial controls. They were physically characterized by assessing: hardening time, adhesion stress, elastic modulus, sorption and solubility at different pHs (6.8 and 7.7); by the obtained values premature detachments, white lesions below the appliance and microfiltration are avoided; its fluidity, film thickness were evaluated and were compared with those obtained from the three commercial adhesives. Storage stability and thermogravimetric analysis were assessed.
