Modified ABO-OGS scores were calculated at the end of treatment. Bracket bonding failures, as well as bracket rebondings and finishing bends because of inaccurate bracket positioning were recorded at every visit. The primary outcome was bracket placement accuracy. The secondary outcome was bracket survival. Outcome assessment was blinded. To compare bracket placement accuracy, paired t-tests were used together with linear mixed models. For the survival analysis, a piecewise Cox model was used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirty-seven patients were randomized to group 1 or group 2. Twenty-seven patients were analyzed for bracket survival, and 26 for ABO-OGS scores. There was no significant difference (P = 0.76, 95% CI: \u22121.18, 0.87) in mean modified ABO-OGS scores between both methods. Among the brackets bonded with computer-aided indirect bonding, 66 brackets (27%) needed rebonding or finishing bends because of inaccurate positioning. Fifty-six brackets bonded with direct bonding (23%) were rebonded or required finishing bends because of inaccurate bracket positioning. The bonding method did not appear to significantly influence the proportion of teeth needing rebonding\/wire bending because of inaccurate bracket positioning. A total of 44 out of 532 brackets got debonded throughout treatment: 22 debonded brackets were totalized with each bonding method (8.3%). There was no statistically significant difference in survival between both bonding techniques. The hazard ratio (HR) computer-aided indirect bonding to direct bonding during the first year was estimated at 1.15 (P = 0.67, 95% CI: 0.61, 2.17). After the first year, the HR indirect to direct was estimated at 0.46 (P = 0.38, 95% CI: 0.09, 2.53).
