[Therapy of class II, division 1. Orthodontics or surgery?].
Concerning five observations of class II division 1, the authors justify therapies they used. Mandibular micrognathia is excluded. Proposed schedules are all based on a precise diagnosis and knowledge of abilities and limits of orthodontics. These limits depend upon orthodontical technics and also, individual factors, particularly if patient is an adult or a child. For a child, orthodontics are preferred and, according with prediction of mandibular growth and child's cooperation, non-extraction therapies are proposed. In adult, correction of deformity ignore such helpful factors as growth and cooperation; nevertheless, it can be successfully treated by orthodontics, using differential extractions, or, if orthodontics are impossible, by orthognathic surgery. Then, surgery will include orthodontical preparation and achievement of dental arches.
