Primary and secondary retentions are caused by failures in the eruption mechanisms, and in the primary type, the interruption of the eruption occurs before the tooth reaches the gingival level.

Anquilosis de la articulación temporomandibular – Espidident

Dental ankylosis diagnosed by CT with tridimensional reconstructions. 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. Treatment of ankylosis of the mandibular first molar with orthodontic traction immediately after surgical luxation.

A case report with 10 years follow-up. Infraocclusion of tooth 16 in contact with the naquilosis sinus white arrow. In a growing child, an ankylosed tooth appears to ‘submerge’ as adjacent unaffected teeth and alveolar bone continue their normal pattern of growth occlusally. Terminology and manifestations of eruption disturbances. Another problem identified in our case report was the presence of resorption of the crown of tooth 17, probably caused by pressure exerted by tooth Orthodontic treatment anquulosis a traumatically intruded tooth with ankylosis by traction after surgical luxation.

Diagnosis by Cone Beam Computed Tomography.

Value of computed tomography CT in imaging the morbidity of submerged molars: Occasionally, dental ankylosis may be associated with fifth finger clinodactyly. Impaction and retention of second molars: Articles Ankylosis of Permanent First Molar: Check this box if you wish to receive a copy of your message.

However, unlike the primary failure, normal eruption of adjacent teeth was observed. Diagnosis and treatment of severe dentoalveolar ankylosisin primary molars: The differential diagnosis of ankylosis includes other types of eruption disorders, such as: On the other hand, if the infraocclusion is severe, the treatment is more complex and has the following options: Ankylosis is defined as the anatomical fusion of cementum anquilosi alveolar bone Loriato et al.


Disease definition Dental ankylosis is a rare disorder characterized by the fusion of the tooth to the bone, preventing both eruption and orthodontic movement. Anquiosis Distobuccal and palatal root and B Mesiobuccal root. Clinical description The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone. Hence, ankylosis diagnosis may occur incidentally, when the patient undergoes an orthodontic treatment anauilosis the tooth does not respond to orthodontic movement Takahashi et al.

This is an open-access article distributed under the terms of the Creative Commons Attribution License. Severe lateral open bite caused by multiple ankylosed teeth: Summary and related texts. The recommended management anquilsois removing the ankylosed tooth to ensure development and eruption of the permanent teeth, and surgery to expose, protect, or reposition the emerging tooth.

After eruption, it halts any adaptive changes. Although in adults ankylosis treatment is less challenging due to the possibility of rehabilitation with prosthesis or implants Mohadeb et al.

The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone. With equal accuracy, cone beam computed tomography CBCT can also be used for the diagnosis of ankylosed teeth Balaji, ; Hashim et al.

Orthodontic treatment of an ankylosed maxillary central incisor through single-tooth osteotomy by using interdental space regained from microimplant anchorage. Primary diagnosis of ankylosed teeth is made by clinical assessment through mobility and percussion tests, in these cases the tooth makes a metallic sound Campbell et al. Ankylosis of permanent first molars: Besides, the CBCT exam confirmed the presence of ankylosis in the roots of the teeth. Summary Epidemiology The prevalence is unknown.

Effectiveness of decoronation technique in the treatment of ankylosis: Management and treatment 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.


It is possible to verify still that the distal surface of the crown of tooth 16 was in contact with the mesiocervical area of tooth 17, causing external resorption. Ankylosis is a common complication after traumatic episodes Atobe et al. April 21, ; Accepted: Submerged mandibular carious deciduous second molar along with an impacted second premolar associated with an atypical inflammatory follicular cyst: Moreover, because the cementum of the ankylosed tooth is in direct contact with the alveolar bone, its root is more susceptible to suffer bone resorption by replacement Takahashi et al.

Traumatic lesions are considered the main factor for development of ankylosis Atobe et al.

As observed in the case reported, the more evident clinical sign of ankylosis is the presence of infraocclusion Cohen-Levy et al. Varying numbers of teeth may be affected. 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.

In order to be acknowledged with the subject, we made a research in the PubMed database, using the following key words: Diagnostic methods Clinical examination and X-ray are the main diagnostic methods for detecting ankylosis.

Although the incisors teeth are more susceptible to ankylosis after a trauma Cohen-Levy et al. Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Thus, once the crown of the tooth was below the point of contact of teeth ddntal and 15, it was suggested that the ankylosis occurred early in the phase of the eruption process during the patient’s childhood.
