牙根彎曲的上顎門齒一定需要矯正治療嗎?

Is Necessary for the Dilacerated Maxillary Central Incisors Orthodontic Treatment?

摘要


一般牙根彎曲(dilacerations)的病例多是因為外傷造成,而現今治療方式常用矯正牽引來拉正,但本病例介紹一位八歲男童,上顎兩顆正中門齒均為牙根彎曲的埋伏齒,經過手術將牙冠露出,其中一顆尚未接受矯正治療,就成功地自然萌發到正常位置;另外一顆則非得用矯正牽引才定位。

Dilaceration is often caused by trauma and treated by orthodontic traction recently. However, an eight-year old boy suffered from dilacerations of both maxillary central incisors and developed differently after the surgery for crown exposure. In this report, one erupted normally without any further treatment but the other had to receive orthodontic treatment to get it move to the right track.
