This report describes the sequelae and subsequent management of a 7-year-old boy who failed to attend follow-up visits after a dental trauma and was initially managed with an active splint. The splint was maintained for 9 months, resulting in an anterior cross-bite, caused by retroclination of the upper incisors. The splint was removed and occlusal build-ups were placed on the molars. Nine months later, the form and shape of the upper dental arch were re-established and the cross-bite was corrected. Four years after the dental trauma, the injured teeth were asymptomatic and had continued root development.
