The aim of this case report was to introduce an appliance that can be used for correcting severe rotation of anterior teeth in pre-adolescent children.
This is a case report of an 11-year-old Iranian boy with a mixed dentition Class I malocclusion defined by a severe rotation of upper left central incisor and a mesiodens between the centrals. The supernumerary tooth was first extracted, and then a Whip device including removable appliance, a cantilever spring and bonded tube on rotated tooth was inserted into his mouth. After 8 months, the upper left central incisor was orthodontically brought into proper alignment. Circumferential supracrestal fibrotomy was done next to overcorrection of the tooth and one week after surgery, the device was removed and the retention was started.
The whip device, a removable appliance can be very effective for correcting severe rotation of anterior teeth.
本病例报告旨在介绍一种可用于矫正青春期前儿童上前牙严重扭转的矫治器。
这是一例关于一名11岁伊朗男孩的病例报告，该男孩处于混合牙列期，患有I类错牙合畸形，表现为左上中切牙严重扭转且两颗中切牙之间存在多生牙。首先拔除多生牙，然后将一种包括可摘矫治器、悬臂弹簧以及粘结在扭转牙上的管的Whip矫治器插入其口腔。8个月后，左上中切牙通过正畸治疗达到了正确的排列。在对牙齿进行过度矫正后，紧接着进行了环切龈上纤维切断术，术后一周拆除矫治器并开始保持。
Whip矫治器，一种可摘矫治器，对于矫正上前牙严重扭转可能非常有效。
