Ankylosis of Teeth
Ankylosis of permanent teeth is a rare disorder characterized by fusion of the tooth to the bone
(‚bony bridge’), preventing both eruption and orthodontic treatment. Infraocclusion is known to be
an reliable sign of ankylosis. The severity of malocclusion related to ankylosis depends on the
developmental stage when ankylosis occurs and the amount of remaining growth. In the growing
child ankylosed teeth provide fixed points from which to study the migration of the teeth of the
affected and unaffected side during this period. 12 subjects with both anterior and posterior
unerupted permanent teeth are presented to focus attention on dental respectively on skeletal
changes in the sagittal, horizontal and vertical plane of space. Indications for operative
intervention and orthodontic management are discussed.
