A method and an orthodontic positioner for preventing or correcting overbite and/or overjet at a mixed dentition stage wherein a patient has permanent incisors and lost, unreplaced canine and deciduous molar teeth. A positioner essentially of a size for a person having incisors the same size as that of the patient but with a full set of permanent teeth (posteriorly to the permanent canine) is trimmed back posteriorly and along the gingival margins to fit in the patient's mouth without abrading the labial-buccal gum surfaces. This will concurrently provide depression of the incisors and guidance of eruption of the permanent canine and bicuspid teeth. |
