英文摘要

Background: Tooth distalization is an effective approach for mandibular prognathism. In the current study, we sought to characterize and compare the static force distribution among the upper maxillary teeth after load application by a novel sliding rod microscrew implantation jig and by a direct traction method using a traction hook. Methods: The sliding rod microscrew implantation jig was used and the microscrew was implanted into the cancellous bone above the mucogingival junction and a traction force (F) of 1.5 N was applied. Static force at the upper canine, first and second premolar and first molar was analyzed. In addition, the entire maxillary arch was distalized by direct traction using a traction hook and the horizontal and vertical traction force on the upper incisor and canine was analyzed. Results: When the load by the jig was applied to anchorage site A, B, O, C, or D, the upper canine, the first and second premolar and first molar experienced no horizontal traction force. As the track force moved down the sliding rod, the horizontal traction force on the upper first molar showed a gradual decline. When the load was applied to anchorage site O, which is at the archwire palne, the upper second premolar and first molar experienced no vertical depressing force. In the direct traction method, the upper incisor and canine received an equivalent horizontal traction force regardless of the anchorage site. When the load was applied to anchorage site O, the distalization force was evenly distributed to the upper incisor and canine. Conclusion: Anchorage site close to the archwire plane provides maximal distalization force and minimal vertical traction force in both methods. The data provides guidance for further optimization of the jig for clinical use.
