2. Anterior open bite associated with breathing problems in an adult patient: a case report
Introduction: Anterior open bite is multifactorial and can be caused by parafunctional
habits, dental or skeletal factors. Early diagnosis of skeletal problems is important as, unlike
dental, they do not regress but often worsen, and usually in adults, their resolution requires a
combination of orthodontic and orthognathic surgery. The aim of this study is to highlight the
association of respiratory problems with anterior open bite in an adult patient.
Aim/ Methods: A patient, aged 38, sought orthodontic treatment at the Orthodontic
Department of the National and Kapodistrian University of Athens, referring to her medical
history respiratory problems. The patient underwent clinical and radiographic examination
and evaluation.
Results: The clinical evaluation (figures 1,2,3,4) of the patient revealed the presence of
anterior open bite, while the radiographic evaluation (figure 4) revealed increased lower and
decreased upper anterior facial height, as well as hyperdivergent skeletal planes. The
patient's anterior open bite was attributed to skeletal etiology, caused and aggravated by the
continuous opening and counterclockwise rotation of the mandible to facilitate breathing.
The lower position of the tongue to facilitate breathing has also led to a narrow upper dental
arch and crowding of the upper teeth (figure 4).
Conclusions: This case report presents an adult patient who was experiencing breathing
problems that acted synergistically with her skeletal pattern in causing anterior openbite. It is
important to diagnose the etiological factors causing and deteriorating the anterior open bite
and to try treating them properly, in an attempt not only to have stable orthodontic results,
but also to improve the quality of patient’s life.
