Abstract
Objective To investigate the effect of two orthodontic traction ways of inversely impacted maxillary central incisor-reverse pull headgear and intermaxillary traction. Methods 30 inversely impacted upper central incisors in 30 patients were selected.They were randomly divided into two groups according to the similar positions of the impacted upper central incisors in 3 dimensions.They were respectively treated with the two traction methods. The traction time and the success rate of the two groups was compared. SPSS17.0 software package was used for Chi-square and t test. Results The success rate among the reverse pull headgear objects was 60% compared with 100% among the intermaxillary traction ones. There was significant difference between the two groups(P<0.05). The reverse pull headgear objects showed significant increase in the duration of treating the impacted upper central incisors(P<0.01). Conclusion After flap operation, the success rate for orthodontic traction of an inversely impacted upper central incisor with reverse pull headgear is significantly higher, and the duration of treatment with reverse pull headgear is longer, compared to intermaxillary traction.关键词
