title: Articulation before and after facial osteotomy.
abstract: We examined the articulation in 41 patients before and after facial osteotomies to correct occlusal defects. Both dental occlusion and articulation improved significantly after surgery. Before surgery there was a direct relationship between the degree of prognathia and the severity of the articulation defect; after surgery in the patients with retrognathia there was a direct relationship between the decrease in the occlusion defect. For other types of occlusal defect these relationship were not established.
