“…Studies have indicated that the optimal bond strength to ensure the required orthodontic movement and to meet the occlusal forces is between 6 and 10 MPa [1,6,[17][18][19]. However, it has also been demonstrated that bond strengths much higher than these values can lead to the formation of enamel cracks and fractures during debonding; some authors have reported that the maximum bond strength should be 20 MPa [20][21][22]. In the present study, any roughening method that provided a bond strength of less than 6 MPa was considered insufficient, based on these in vitro studies.…”

“…Debonding can also occur between the tube and the orthodontic resin, and although a number of treatments are described to improve adhesion to enamel [4][5][6] , only a few are proposed to increase bonding on the metal surface. Mechanical treatments designed to increase roughness, such as aluminum oxide blasting, the use of a diamond drill 9 , and chemical treatment with the use of silane 10 , are amid the reported alternative treatments for the metal surface.…”

“…Como resultado da grande valorização da estética e da consciência da necessidade de tratamento ortodôntico, o número de pacientes adultos que procuram por tratamento ortodôntico aumentou consideravelmente [1,2]. Contudo, neste grupo de pacientes, pode ser encontrada maior frequência de restaurações de amálgama, de resina ou de cerâmica [1,2].…”

“…Contudo, neste grupo de pacientes, pode ser encontrada maior frequência de restaurações de amálgama, de resina ou de cerâmica [1,2]. Esta situação está diretamente relacionada a problemas associados à função e à estética na dentição permanente que podem ocorrer como resultado de fratura ou de lesão cariosa extensa [3].…”
