Bilateral posterior open bite due to failure of primary eruption-a treatment approach

Abstract

Hariclea Morosan

Posterior open bite is a challengeable anomaly and the treatment outcome depends very much on its etiology. In the present case, we describe the therapeutic management of a bilateral posterior open bite due to failure of eruption of molars and premolars. Moreover, the patient had partially reincluded deciduous molars, all four second premolars anodontia, a biretrusive profile and high angle facial pattern. Before starting the orthodontic treatment, the patient was removed all deciduous molars, following MBT brackets bonding aiming for tractioning down to the occlusal plane the upper right molars, closing all the spaces, flatten the curve of Spee and protrude both arches. After the active treatment (2 years and 10 months), essix retainers were given to wear 12/24. Assessment of the medical and dental history, trauma or other clinical conditions resulted in a therapeutic diagnosis that could be addressed with the proper orthodontic treatment achieving satisfactory results.
