| Abstract | ||
| Aims: This study was aimed to compare the effects of two different techniques on the position of maxillary incisors during the intrusive movement. Materials and Methods: The sample consisted of two groups, the utility intrusion arch and continuous intrusion arch groups. Upper typodont arch of class II division I was used and the arches were activated to deliver 60 gram of force. Pre and postoperative digital images were taken and analyzed using Autodesk AutoCAD software™. For each group six parameters were measured and compared. A significance value of 0.05 was predetermined. Results: Significant difference was found in vertical change of estimated midpoint of root position, axial inclination, anteroposterior position of incisal edge, relative contribution of torque and protrusion to the change in inclination and insignificant difference in vertical change of incisal edge position. Conclusions: Maxillary incisors intrusion with a minimal protrusion could be achieved with the continuous intrusion arch technique | ||
