title: Orthodontic treatment of a stubborn palatally ectopic canine: a case report.
abstract: This is a case report that highlights a different treatment approach in dealing with palatally ectopic canines. The modified transpalatal arch with an 'active' arm was used to align a palatally ectopic canine with 'push' mechanics after the initial use of more conventional 'pull' mechanics (piggy-back archwire technique) had failed.
