This study was undertaken to test the theory that different kind of metal alloys can influence the bond strength of the silane treated bracket bases. Seven different types of brackets, each with different metal properties, were tested. 20 brackets of each type were used, half of them were silanated with a special Silicoater treatment. The following conclusions can be made: 1. The silane coated plain bracket demonstrated a higher bond strength than all the tested untreated brackets; 2. the brackets of the company Dentaurum demonstrated a statistically significant higher bond strength than the brackets of all the other companies.
