The recommended management includes removing the ankylosed tooth to ensure development and eruption of the permanent teeth, and surgery to expose, protect, or reposition the emerging tooth. The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone. Therefore, depending on the level of infraocclusion, it may trigger several clinical implications during jaws development and growth, e. Effectiveness of decoronation technique in the treatment of ankylosis: Ankylosis can affect both sexes Silva and it is more frequent in deciduous teeth Dental ankylosis can affect both primary and permanent teeth, may occur at any time during eruption and can lead to submergence.

The importance of the early diagnosis of ankylosis should be highlighted, because the maxillomandibular growth turns the abquilosis and surgical treatments more complex, due to the worsening of occlusal problems and deficiencies of the alveolar bone. Etiology remains uncertain but a genetic predisposition to ankylosis with autosomal dominant inheritance has been suggested.
However, for identifying the root region extent and exact location where ankylosis is present, the examination by three-dimensional imaging is essential Paris et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License.
Whereas computed tomography CT is considered superior to radiography Kirziolu et al. Ankylosis is defined as the anatomical fusion of cementum with alveolar bone Loriato et al. Impaction and retention of second molars: In a growing child, an ankylosed anqjilosis appears to ‘submerge’ as adjacent unaffected teeth and alveolar bone continue their normal pattern of growth occlusally.
Radiographic testing enables assessing only proximal regions of possibly affected roots.
The primary failure of anquilossis eruption mainly affects the posterior teeth Rhoads et al. The hypodense image identified in the occlusal surface is a dental cavity affecting enamel and dentine Fig. A retrospective followup study.

Ankylosis of permanent first molars: Primary failure of eruption: Moreover, radiographic examination is also inaccurate Kirziolu et al. Orthodontic treatment of an ankylosed maxillary central incisor through single-tooth osteotomy by using interdental space regained from microimplant anchorage.
Late diagnosis of dentoalveolar ankylosis: When infraocclusion is less than 5 mm, it is possible to carry out restorative treatment with the use of restorative materials or prosthetic crowns for reestablishing dental occlusion Lim et al. Treatment of ankylosed mandibular first permanent molar. Comparing clinical signs, symptoms and CBCT image, the hypothesis of dental ankylosis was suggested, because infraocclusion of tooth 16 was below the contact area of the teeth 17 and 15 Fig.
In slight cases, follow up is recommended Lim et al.
Dental ankylosis is a rare disorder characterized by the fusion of the tooth to the bone, preventing both dentaal and orthodontic movement. Submerged mandibular deental deciduous second molar along with an impacted second premolar associated with an atypical inflammatory follicular cyst: Terminology and manifestations of eruption disturbances. Value of computed tomography CT in imaging the morbidity of submerged molars: Although the incisors teeth are more susceptible to ankylosis after a trauma Cohen-Levy et al.
Summary and related texts. On the other hand, if the infraocclusion is severe, the treatment is more complex and has the following options: In the present case, because the tooth was a molar tooth, radiographic diagnosis is even more challenging, for it is a multiradicular tooth due to overlapping structures. However, ankylosis early diagnosis is difficult, for in the beginning areas absence periodontal ligament are small and the tooth still presents mobility Cohen-Levy et al.
Although periapical x-rays are daily used in dental clinics, their value is limited for diagnosisof ankylosed teeth Paris et al. Other search option s Alphabetical list.
Infraocclusion of tooth 16 in contact with the maxillary sinus white arrow. After eruption, it halts any adaptive changes. The present study contains a case report of a male patient with ankylosis in tooth 16 diagnosed by CBCT, aiming at providing information for dentists about this anomaly, its characteristics and situations in which CBCT should be indicated.
