[The role of restorative oral rehabilitation in orthodontic treatment of cleft lip and palate patients].

The use of a proposed restorative appliance allows: to create the continuity of the upper dentition that harmonizes the distribution of forces from the active orthodontic arch; increases the stability of the teeth in the areas of the upper jaw adjacent to the cleft (incisors and canines) and prevents their unwanted displacement; promotes directional movement of the teeth; in the retention period, to maintain the achieved expansion of the dentition while maintaining space for the future fixed prosthesis; isolate the mouth of the anterior palate; hold the achieved position of the fragments of the upper jaw until bone grafting.
