- Curve of Spee leveled
- Arches aligned and coordinated
- Alignment of both arches through derotation
- Aesthetic smile linewas achieved
- All treatment goals were achieved case
- Harmonic arches were achieved
Comments
- The premature contact between anterior teeth leading mandibular displacement was corrected by proclination of upper anterior teeth and upper and lower arch expansion
- Different patterns of elastics were used throughout the treatment to help arch coordination
- Extrusion with attachments worked great with leveling of curve of Spee and settling the bite
- Periodontal condition was maintained
- Root canal treatment was completed on the upper left canine (23).
- Prior to final refinement we did composite build up of upper anterior teeth after correction of the anterior crossbite
