Dilacerated incisors and congenitally displaced incisors: three case reports.

Three cases of dilacerated incisors and congenitally displaced incisors are reported. Dilaceration of central incisors occurs following trauma to the deciduous dentition. Generally these teeth are so severely malformed that they have to be extracted. Congenital displacement of the central incisors is an idiopathic condition with a generally favourable prognosis for orthodontic alignment.
