---|---|---|---|---|
Primary | Bracket failure rate | Patients with repeated bond failures caused by habits or trauma would be excluded from further analysis.only counting the number of brackets that broken . | 6 months | |
Secondary | Adhesive remenant index | Assessment of the amount of remnant adhesive left post bracket failure (for both methods).This index system was developed on the basis of a pilot study of 20 extracted teeth and the criteria were as follows: score 0 = no adhesive left on the tooth; score 1 = less than half of the adhesive left on the tooth; score 2 = more than half of the adhesive left on the tooth; and score 3 = all adhesive left on the tooth with a distinct impression of the bracket mesh. | 6 months |
