Class I – Crowding, Shallow Overbite (SureSmile® Aligners)

Patient’s chief complaint(s): Doesn’t like the alignment of her “front” teeth. She had relapse after previous orthodontic treatment with fixed braces provided by another practitioner, but now wanted to have a perfect smile for her wedding day.

Dental crowding is a symptom of a tooth-size–arch-length discrepancy. Doctors can address crowding by increasing the size of the dental arch with expansion or they can decrease the size of the teeth or tooth mass with interproximal enamel reduction (IPR) or extraction to resolve the discrepancy. In some cases, doctors might address crowding with a combination of both expansion/proclination and IPR. Regardless, each method has an impact on the opposing arch, so when patients like this case, present with moderate crowding on the lower arch and very little crowding or alignment concerns on the upper arch, the challenge becomes focused on how to level and align the lower arch knowing proclining the lower incisors may have a negative consequence in minimising the overjet or creating negative overjet.
