Clear Aligners | Localized Underbite _ Orthodontic Case

Orthodontic cases

Clear Aligner Orthodontics

Case Presentation:
The young man felt that his teeth differed from others. He experienced difficulty during chewing—particularly with incising/biting actions or when eating finer foods—and noticed that both masseter muscles felt fatigued. He also felt that his chin was deviated to one side, resulting in facial asymmetry. He wished to undergo orthodontic treatment.

Treatment Plan:
Clinical examination revealed loss of incising (cutting) function of the anterior teeth. The anterior crossbite had led to facial deviation with poor left-right symmetry, poorly matched narrow maxillary and mandibular arches, and compromised posterior masticatory function. The correction plan employed clear aligner orthodontics to retract the lower anterior teeth and distalize the mandibular molars, resolving the impaired anterior incising function and the facial deviation; the maxillary arch was expanded to enhance bilateral posterior masticatory function.

Treatment Outcome:
The teeth are well aligned, the anterior crossbite has been resolved, and incising function of the front teeth has been restored, benefiting masticatory efficiency. Following maxillary arch expansion, the patient's respiratory (airway) function has improved markedly. The face is also more symmetrical.
