Maxillary transverse deficiency is a common problem in orthodontics. It could be skeletal and/or dental origin and is often manifested by unilateral or bilateral posterior cross bite. Clinically, the skeletal width of maxilla and mandible, the intermolar width and the buccolingual inclination of maxillary and mandibular posterior teeth (curve of Wilson) are the key factors on the diagnosis of transverse problems. For a growing patient, the transverse facial growth is usually completed before sagittal and vertical growth. In this lecture, the transverse growth of maxilla and mandible, and the transverse development of the dentitions will be discussed. Nowadays with the advent of cone beam CT, the skeletal width of maxilla and mandible, the buccolingual inclination of posterior teeth and their positions in the basal bone can be easily determined. In the treatment of transverse problems, rapid palatal expansion (RPE) is often used in children, and TADs supported RPE in young adult. However, for older adults, the surgically assisted rapid palatal expansion would be a better choice not only to expand the maxilla successfully but also provide good stability. In this lecture, the state-of-the-art diagnosis and treatment modalities on the transverse problems will be presented. For the last 30 years at the University of Pennsylvania, extensive clinical studies have been conducted on the effects of rapid palatal expansion on nasomaxillary complex, which will be also discussed.
