- The aim of this study was to test under thermo stress the effect of
- various adhesives on the bonding strength of brackets with a new
- retention mechanism in comparison to brackets with a conventional
- retentive basis. In the test 17 different adhesives and metal brackets
- with two different retention mechanisms were used. One group of metal
- brackets was coated by means of the Kulzer silane coating procedure
- and the other had a mesh basis. The latter served as the control
- group. Both were held in place by adhesives and their bonding strength
- tested. The following conclusions were drawn: 1. Both of the bracket
- types demonstrated the highest bonding strength with the mixed
- composites (paste/paste). 2. The silane coated bracket bases
- demonstrated altogether higher bonding strength than the mesh
- brackets, but the difference with the light-cured and the
- epoxy-adhesives was only statistically significant.
