Highlights
Pediatric dentists need to be aware of
the multidisciplinary work involved in
the treatment of anterior open bite as
a result of its multifactorial etiology.
This case report presents an
orthodontic treatment option based
on the elimination of confounding
factors during diagnosis of the
malocclusion.
This article seeks to delegate
competencies regarding the treatment
of anterior open bite since the dentist
is not able to fully intervene in some
circumstances.
Abstract
Open bite can be defined as an absence of occlusion, most frequently located in the anterior region of dental arches and its etiology is multifactorial. We present a clinical case of an 8 years and 10 months child presenting an anterior open bite (AOB) with transverse maxillary deficiency caused by tongue thrust during mixed dentition. The malocclusion was corrected by means of a McNamara expander with a palatal crib jointly with the association of speech therapy for tongue repositioning, and otolaryngology to treat adenoid hypertrophy due to its correlation with AOB. The multidisciplinary approach was effective in correcting the malocclusion with stable results after 2 years post-treatment.
