Dental ankylosis can affect both primary and permanent teeth, may occur at any time during eruption and can lead to submergence. The disorder may result in loss of the retained molar and neighboring teeth due to caries and periodontal disease, and in deformation of the facial skeleton reduction in the height of the lower face, relative mandibular prognathism, posterior open bite.
A retrospective followup study. Therefore, depending on the level of infraocclusion, it may trigger several clinical implications during jaws development and growth, e. 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, anquilozis reposition the emerging tooth. Articles Ankylosis of Permanent First Molar: Trauma, inflammation or infection may play a causative role.
The importance of the early diagnosis of ankylosis should be highlighted, because the maxillomandibular growth turns the orthodontic and surgical treatments more complex, due to the worsening of occlusal problems and deficiencies of the alveolar bone. Moreover, these are also considered causal factors: As observed in the case reported, the more evident clinical sign of ankylosis is the presence of infraocclusion Cohen-Levy et al.
Orphanet: Anquilosis dental
When infraocclusion is less than 5 mm, it is possible to carry out restorative treatment with the dnetal of restorative materials or prosthetic crowns for reestablishing dental occlusion Lim et al. Ankylosis treatment depends on infraocclusion degree. On the other hand, if the infraocclusion is severe, the treatment is more complex and has the following options: Orthodontic treatment of a traumatically intruded tooth with ankylosis by traction after surgical luxation.
Etiology remains uncertain but a genetic predisposition to ankylosis with autosomal dominant inheritance has been suggested.
Although there is no cement union to the anwuilosis bone in these cases, they present clinical features very similar to ankylosis. Studies on diagnosis of ankylosis using CT are limited Kitai et al. The ethics committee on human research exempted this study approval since only CBCT images would be disclosed without the possibility of patient identification.
However, for identifying the root region extent and exact location where ankylosis is present, aqnuilosis examination by three-dimensional imaging is essential Paris et al. CBCT is therefore an important diagnostic tool for examination and treatment planning Balajisafe for professionals and patients as well. However, in the primary failure, the treatment is more complex, frequently involving all snquilosis teeth adjacent to the affected tooth, resulting in lateral opened bite Frazier-Bowers et al.

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. Infraocclusion of tooth 16 in contact with the maxillary sinus white arrow. Although periapical x-rays are daily used in dental clinics, their value is limited for diagnosisof ankylosed teeth Paris et al.
The primary failure of the eruption mainly affects the posterior teeth Rhoads et al. Conebeam computed tomography in orthodontics: It should also be noted that ankylosis may affect teeth that have been extracted and subsequently reimplanted Takahashi et al.
Dental ankylosis diagnosed by CT with tridimensional reconstructions. Ankylosis is a common complication after traumatic episodes Atobe 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.
With the lack of accessibility of genetic tests in dental offices to confirm the occurrence of primary failure Rhoads et al. Clinical assessment combined with imaging exams can aid diagnosis.

Severe lateral open bite caused by multiple ankylosed teeth: A case report with 10 years follow-up.
A case report of a discordant twin pair. In a growing child, an ankylosed tooth appears to ‘submerge’ as adjacent unaffected teeth and alveolar bone continue their normal pattern of growth occlusally. Treatment ansuilosis ankylosed mandibular first permanent molar.
A comparative study for image quality and radiation dose of a cone beam computed tomography scanner and a multislice computed tomography scanner for paranasal sinus imaging.
Comparing clinical signs, symptoms and CBCT image, the hypothesis of dental ankylosis was suggested, because infraocclusion of tooth 16 was below the contact area dengal the teeth 17 and 15 Fig. Multiplanar reconstructions MPR were obtained and in the panoramic reconstruction, in sagittal and coronal planes, it was observed that in addition to dwntal teeth 18 and 28, the patient had tooth 16 partially erupted, with its roots in contact with the maxillary sinus and absence periodontal ligament space along the roots Figs.
Use of dentomaxillofacial cone beam computed tomography in dentistry. In complex cases, CBCT may also be required for surgical treatment of ankylosed teeth Balajiwhen the tooth is near noble structures, e.
