Class I with Class III tendency - Crowding (SureSmile® Aligners)
Patient’s chief complaint(s): Doesn’t like her smile or her crowded teeth.
Patient presented with crowding in the upper and lower arches with the amount of crowding being more significant in the lower arch.
In this case shared by Dr. Ed Lin, see how doctors can use pre-submission techniques like placing elastomeric separating elastics between teeth prior to scanning them so that access for them to perform Interproximal Reduction (IPR) during the treatment period is much easier.
Dr. Lin is an orthodontist with a private practice in Green Bay, WI.
Diagnosis
• Slightly asymmetric upper and lower arches
• Upper: Mild crowding
• Lower: Moderate crowding
• Moderate deep bite
• Uneven incisal edges
Treatment Plan
• Move upper and lower first bicuspid to first bicuspid to resolve crowding (while maintaining posterior occlusion)
• Placed elastomeric spacers interproximally for lower anterior teeth prior to starting aligner therapy to enable easy access to perform IPR at the start of treatment
• Perform IPR in the first bicuspid to first bicuspid region
• Correct all rotations
• Parallel her crowns
•Level her incisal edges
Treatment Outcome and Follow-up
Modalities: SureSmile® Software, Aligners & Propel Orthodontics VPro ™
Duration: 4.25 months
# Aligners: U: 7+1 = 8 L: 9+2= 11
All main objectives were achieved:
• Resolved upper and lower crowding
• Achieved upper and lower arch symmetry
• Levelled the lower arch’s curve of spee
• Intruded lower anterior teeth to open her bite
• Levelled incisal edges of upper and lower teeth
Retention: Upper arch retained with a clear retainer. Lower arch retained with a lingual retainer bonded cuspid to cuspid and a clear retainer worn over it at night.
