Maxillary Protraction
"Maxillary protraction is an alternative non-surgical approach to correct the Cl III malocclusion. At ages 11- 14, the maxillary sutures have not fused and can be mobilized by alternating weekly expansion and constriction with a rapid palatal expander (RPE), thereby allowing the maxilla to be protracted in order to correct the underbite. This treatment is offered to the patients, age 11-14, who have the Cl III malocclusion with or without cleft lip and palate."
Orthognathic Surgery
The orthognathic surgery is the current standard of care for treating the Cl III malocclusion after pubertal growth. This treatment is offered to the patients, after pubertal growth, who have the Cl III malocclusion with or without cleft lip and palate.
