Abstract
Objective To compare the degree of tolerance.the periodontal health and the failure of brackets bonded between patients with self-ligating brackets and conventional straight wire brackets. Methods A total of 30 patients accepting orthodontic treatment in our department during 2006 to 2008,aging 12~16 years,including 15 patients bonded with self-ligating brackets and 15 patients bonded with conventional brackets.They were surveyed with questionnaire to record the degree of discomfort within the first 7 days after archwire placement.The gingival index (Gl),sulcus bleeding index (SBI),and plaque index (PLI) of mandibular incisor were recorded respectively at 1 month,3 months and 6 months. The times of rebonding were recorded within 1 year after first bonding. Results There was no significant difference in tolerance between the two groups of patients with self-ligating brackets and conventional straight wire brackets within 7 days after initial alignment (P>0.05).The periodontal index and the rate of rebonding were significantly lower in the group of self-ligating brackets. Conclusion There is no difference between conventional brackets and self-ligating brackets in the degree of discomfort. But self-ligating brackets have the advantage of keeping periodontal health and decreasing the rate of rebonding.关键词
