METHODS: We analyzed a sample of forty-eight young female adults, aged between 10, 19 and 40 years old, with a mean age of 30.9 years, who had balanced profile and passive lip seal. Cone beam computed tomographies were performed at rest and wide smile postures on the entire sample which was divided into three groups according to individual facial types. Soft tissue features analysis of the lips, nose, zygoma and chin were done in sagittal, axial and frontal axis tomographic views. RESULTS: No differences were observed in any of the facial type variables for the static analysis of facial structures at both rest and wide smile postures. Dynamic analysis showed that brachifacial types are more sensitive to movement, presenting greater sagittal lip contraction. However, the lip movement produced by this type of face results in a narrow smile, with smaller tooth exposure area when compared with other facial types. CONCLUSION: Findings pointed out that the position of the upper lip should be ahead of the lower lip, and the latter, ahead of the pogonion. It was also found that the facial type does not impact the positioning of these structures. Additionally, the use of cone beam computed tomography may be a valuable method to study craniofacial features.<\/jats:p>","DOI":"10.1590\/s2176-94512013000600007","type":"journal-article","created":{"date-parts":[[2014,1,15]],"date-time":"2014-01-15T13:37:44Z","timestamp":1389793064000},"page":"38-44","source":"Crossref","is-referenced-by-count":2,"title":["Cone
