Abstract :
This article describes a case report of a patient with knife edge alveolar ridge where orthodontic tooth movement was previously impossible into which rapid canine retraction for 8mm was done by use of a new technique of combining ridge split expansion with piezocision and thereby producing a regional acceleratory phenomenon and rapid canine retraction by custom made tooth borne distraction device.
