 note = {application/pdf, Dentoalveolar bimaxillary protrusion is a quite common malocclusion in the Japanese population and has been accepted as a normal occlusion for a long time. Recently, not only correction of crowding teeth but also cosmetic concerns about protrusive lips due to dentoalveolar protrusion have increased under the circumstances of a more globally oriented Japanese society. The horizontal and vertical relationship between the upper incisors and lip is esthetically quite important, exclusively to young female patients. The frontal face may also be considered to require a good smile balance (line) on anterior teeth alignment, and a good upper lip contour, in orthodontic treatment outcomes. In this case report, four first bicuspid extractions were achieved and the results obtained satisfied the patients' main complaints of initial protrusive lips and difficulty in lip closing. The two cases were successfully treated with good posterior occlusion and an excellent profile, and are now in retention with removable retainers.},
