第臼歯遠心移動のためのトランスパラタルバーを使用する口蓋ミニインプラント法
Implant anchorage (Mini-screw) may supplies reliable anchorage for orthodontic tooth movement. Palatal posterior region for mini-screw implantation could be regarded as inappropriate one. However, the author has used the palatal mini-screw anchorage with trans-palatal -bar for molars distalization. The author introduces the procedures that is visualized through a case class I crowding of 20 years female below. The period of tooth movement was 11 months.
