Non-surgical treatment of anterior open bite and its assessment using the Dawjee Analysis: a case report
MetadataShow full item record
Anterior open bite (AOB) is a dentofacial problem occurring more commonly in race groups of African origin. Although multi-factorial, the aetiology exerts its influence in tandem with craniofacial development. Diagnosis is confirmed by a cephalometric assessment and points either to a skeletal origin, a dental source, or both. Depending on the time of diagnosis and severity of the condition, treatment can vary from interceptive procedures, orthodontics only, or a combination of orthodontic treatment and orthognathic surgery. A case study is presented of an adult female with AOB who was treated nonsurgically. The diagnosis, treatment technique and outcome are described, as well as a pre- and post-treatment evaluation of the cephalograms using the Dawjee analysis. Comparison of pre- and post-treatment cephalometric values show a definite dentofacial improvement, and identifies specific morphologic areas that have changed as a result of treatment. Transformations in anteroposterior maxillary and mandibular positions and orientation are readily detectable, as well as a repositioning of the alveolar processes. While pre and post treatment cephalometric values presented for this patient compare well, these values are case specific and cannot be implemented widely unless the analysis is applied to a larger and more representative population sample and standardised measurements have been established.
