Summary

Results achieved

• Class I relationship achieved
• Class I relationship maintained
• Functional canine guidance on both sides
• Normal  overjet and overbite achieved
• Deepbite improved
• Significant improvement of overbite
• Midlines coincident
• Proper axial inclination of incisors
• Curve of Spee leveled
• Arches aligned and coordinated
• Arch form improved
• All treatment goals were achieved case

Comments

• Moderate anchorage G6 First premolar extraction was used to close the extraction space in the upper arch
• In the lower arch, the mesialization of the lower posterior segment on the right side was required in order to achieve good interdigitation of the occlusion
• The intrusion of the lower anterior segment aided in improving the initial deep bite
• Increased palatal root torque was placed on both upper and lower incisors to prevent lingual tipping of these teeth as the extraction spaces were closed.
• Light intermaxillary Class II elastics were employed to help coordinate the arches
• At the end of orthodontic treatment, fractured enamel of the upper left central incisor was restored.
