Facial Convexity and Posterior Divergence: The Class II Deformity
There is little question that the Class II skeletal deformity is the most common developmental deformity that confronts surgeons. It is estimated by the United States Public Health Service that approximately 5% of North American Caucasians have some degree of mandibular deficiency. Not infrequently, underdevelopment of the lower jaw is seen in association with vertical dysplasia of the maxilla, the most common condition being vertical maxillary excess with or without anterior open bite.
