Abstract

PEREIRA, Felipe Ladeira; IWAKI FILHO, Liogi; CAMARINI, Edevaldo Tadeu  and  PAVAN, Angelo José. Laboratorial study to test traction resistance of Fill Magic® light-cured resin intended for orthodontic traction of unerupted teeth. Rev. Dent. Press Ortodon. Ortop. Facial [online]. 2006, vol.11, n.1, pp.77-83. ISSN 1980-5500.  http://dx.doi.org/10.1590/S1415-54192006000100011.

AIM: comparisson of two composite adhesives used for orthodontic traction procedures. METHODS: this article compared the bonding capability and practice of two resins for direct orthodontic traction: the 3M®'s Concise®, been sold in the market for a few years and the reference for this kind of procedure; and Vigodent®'s Fill Magic®, which technique is much simpler according to the manufacturer. Forty third molars were included into acrylic resin and divided in two groups of 20, one for each resin. Once the brackets were bonded, the specimens were submitted to horizontal force (10 of each group) and vertical (10 of each group), till the bracket got lost. The score obtained in the universal testing machine were recorded and compared by the average to set the advantages and disadvantages of each one. RESULTS AND CONCLUSION: Despite the recorded values of the Fill Magic® were much lower than the Concise®'s, they were far enough for direct orthodontic traction.
