Abstract

The horizontally impacted unerupted canine is considered orthodontically difficult to treat. A treatment method using a modified Nance Palatal Arch with a vertical bar extending into the buccal vestibule area is used to alter the eruption path of the impacted canine crown, hence avoiding interference with the lateral incisor root. The anchorage is re-inforced by the palatal component of the Nance Arch. The results are highly predictable and undesirable side-effects can be minimized. The structure of the special appliance, the treatment mechanism and the sequence of the treatment are described in this article.
