[Intrusion of the definitive incisors]

Intrusive luxations make up about 5% of the dental traumata on permanent front teeth. Clinical and radiological findings are described. Practical guidelines are given for the treatment of intruded teeth, with or without completed root formation, based on literature findings and clinical experience. Much attention is given to the question whether one should prefer orthodontic extrusion or choose for surgical reposition followed by immobilisation in cases of intrusive luxation of teeth with closed apices. Clinical cases are presented.
