评论

  • 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
