Correction of upper impacted canines in vestibular position with segmental osteotomy advancing the incisal block. Apropos of 5 cases

The author reports on 5 cases of segmental osteotomy advancing the upper incisal block, in the treatment of vestibular retention of an upper canine associated with an upper retro-alveolitis and/or brachypremaxillitis. This surgery is proposed as an alternative to the extraction of the 4 pre-molars, which is usually done in these cases of apparent disharmony.
