Transmaxillary osteogenesis distraction combined with orthopedics and orthodontics in the correction of a severe retrusion of the upper maxilla.
A patient having adequate records and diagnosed as having Binder syndrome is presented. Nasomaxillary hypoplasia requires a definitive treatment, use of bone grafts, upper maxillary osteotomies, and advancement or a combination of both. Bone grafts can be reabsorbed, and complete maxillary advance modifies normal occlusion in a certain way, because the posterior sector is not compromised. The aim of this case treatment is to create a new osseous surface that makes the eruption of the permanent dental pieces easier and gives the correct skeletal position to the upper maxilla with distraction osteogenesis combined with an orthopedic appliance, transmaxillary segment osteotomy, and subsequent orthodontics. The absence of the osseous surface in the upper maxilla and the presence of supernumeraries in the anterior region determined the permanence of most of the temporary dental pieces, resulting in the impossibility of making the exchange to permanent dental pieces. The technique and the devices are simple and easy to manipulate. After the treatment, an adequate dental relation is restored as well as effective advance of the upper maxillary bone; thus, an excellent functional and stable esthetic result is achieved, avoiding any complication of velopharingeal incompetence.
