The ethics committee on human research exempted this study approval since only CBCT images would be disclosed without the possibility of patient identification. In this context, the CBCT imaging allows identified with high accuracy all root surfaces affected by ankylosis and it may be requested for accurate diagnosis of the presence and location of ankylosis in molar teeth, showing anatomical details that could not be visualized in conventional radiographic techniques because of their two-dimensional nature and overlapping structures.

With the lack of accessibility of genetic tests in dental offices to confirm the occurrence of primary failure Rhoads et al. Bone morphology after delayed tooth replantation – case series.

Primary failure of eruption: Primary diagnosis of ankylosed teeth dentl made by clinical assessment through mobility and percussion tests, in these cases the tooth makes a metallic sound Campbell et al.

In the present case report, the close relationship of tooth 16 roots with the floor of the maxillary sinus may also hinder their surgical extraction and lead to complications such as oroantral communication.

In the present case, as in the primary eruption failure, a posterior tooth was affected. Dentoalveolar ankylosis is an anomaly of dental eruption, caused by mechanical failure of eruption Frazier-Bowers et al. Value of computed anquilosos CT in imaging the morbidity of submerged molars: Male patient, 16 years old was referred for clinic of the Oral Radiology to perform CBCT, in order to plan the next steps of the orthodontic treatment.


Clinical description The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone. Ankylosis is defined as the anatomical fusion of cementum with alveolar bone Loriato et al. Terminology and manifestations of eruption disturbances. Diagnosis of ankylosis in permanent incisors by expert ratings, Periotest and digital sound wave analysis.

Orthodontic treatment of a traumatically intruded tooth with ankylosis by traction after surgical luxation. Besides, percussion clinical tests and metallic sound produced are only reliable in about one-third of the cases Cohen-Levy et al.

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. Therefore, depending on the level of infraocclusion, it may trigger several clinical implications during jaws development and growth, e.

An atypical presentation of mechanical failure of eruption of a mandibular permanent molar: Dental ankylosis is a rare disorder characterized by the fusion of the tooth to the bone, preventing both eruption and orthodontic movement. In such cases, the tooth may erupt partially, becoming relatively submerged or may not erupt Frazier-Bowers et al. In a growing child, an dengal tooth appears to ‘submerge’ as adjacent unaffected teeth and alveolar bone continue their normal pattern of growth occlusally.

Thus, once the crown of the tooth was below the point of contact of teeth 17 and 15, it was suggested that the ankylosis occurred early in the phase of the eruption process during the patient’s childhood.


Moreover, radiographic examination is also inaccurate Kirziolu et al. A comparative study for image quality and radiation dose of a cone beam computed tomography scanner and a multislice computed tomography scanner for paranasal abquilosis imaging.

Additional information Further information on this disease Classification s 2 Gene s 0 Clinical signs and symptoms Other website s 0. Permanent molars are less frequently affected than deciduous molars. However, since only one third of the patients present these clinical signs Cohen-Levy et al. Ankylosis treatment depends on infraocclusion degree. Studies on diagnosis of ankylosis using CT are limited Kitai et al. Impaction and retention of second molars: The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone.

On the other hand, dehtal the infraocclusion is severe, the treatment is more complex and has the following options: With equal accuracy, cone beam computed tomography CBCT can also be used for the diagnosis of ankylosed teeth Balaji, ; Hashim et al.

Three-dimensional evaluation of a rare case with multiple impacted teeth using CT. 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.
