Interdisciplinary management of an adult patient with significant restorative treatment needs and a complex malocclusion

Transverse maxillary deficiency may be associated with dental crowding, compromised aesthetics and impaired function. Non‐surgical correction of maxillary transverse deficiency through rapid maxillary expansion is routinely performed for young patients; however, surgical intervention is generally required for adults. An interdisciplinary treatment approach is necessary to achieve the desired treatment objectives for challenging cases. This case report demonstrates a pleasing treatment outcome for a patient with a severe maxillary transverse deficiency, significant crowding and extensive active caries.
