Abstract
Occlusal re-construction was non-prosthetically achieved in a case of bilateral cleft lip and palate with antero-lateral stenosis of the maxillary dentition, without performing lateral expansion. Changes in the maxillary dental arch width were evaluated. This paper reports on the treatment course and occlusal stability.
The patient was a female with bilateral cleft lip and palate showing skeletal mandibular protrusion due to maxillary hypo-growth with protrusion and inferior descent of the intermediate jaw. Although lateral expansion was performed in the growth period, relapse occurred thereafter. Therefore, at the final treatment, surgical orthodontic treatment with Le Fort type I osteotomy was performed to improve the overlap, without expanding the maxillary dental arch width. Furthermore, the canines were arranged in the bilateral alveolar cleft areas to establish occlusion. Serial evaluation confirmed that the maxillary dentition width at the time of the initiation of retention remained the same at the time of re-diagnosis, showing occlusal stability.
