Resumen
Success in the orthodontic movement is directly related to the sliding ability of the arches in the brackets’ and tubes’ slot. The contact between the arch and the slot surface produces friction that is defi ned as a set of forces that act on the tooth opposing the tooth movement. Objective: To compare bracket and slot irregularities of four conventional ligation systems and one self-ligation system. Material and methods: Using a digital microscope 75 brackets, 15 of each commercial brand, were observed. An image capture was obtained and evaluated by 4 observers who registered the observed irregularities in the base and slot of each bracket, for later percentage comparison. Results: Self-ligating brackets showed the lower percentage of irregularities in the total number of their surfaces as well as in the slot.
