Although periapical x-rays are daily used in dental clinics, their value is limited for diagnosisof ankylosed teeth Paris et denta. The hypodense image identified in the occlusal surface is a dental cavity affecting enamel and dentine Fig.
The ethics committee on human research exempted this study approval since only CBCT images would be disclosed without the possibility of patient identification.
Anquilosis del Primer Molar Permanente: Diagnóstico por Tomografía Computarizada con Haz Cónico
Use of dentomaxillofacial cone beam computed tomography in dentistry. Terminology and manifestations of eruption disturbances. Etiology Etiology remains uncertain but a genetic predisposition to ankylosis with autosomal dominant inheritance has been suggested. Therefore, depending on the level of infraocclusion, it may trigger several clinical implications during jaws development and growth, e.
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. However, in the primary failure, the treatment is dentxl complex, frequently involving all the teeth adjacent to the affected tooth, resulting in lateral opened bite Frazier-Bowers et al.
Bone morphology after delayed tooth replantation – case series. Articles Ankylosis of Permanent First Molar: Diagnosis by Cone Beam Computed Tomography. 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 In the initial stages, the primary failure of eruption and ankylosis may have similar clinical presentations Frazier-Bowers et al.
In order to be acknowledged with the subject, we made a research in the PubMed database, using the following key words: Orthodontic treatment of an ankylosed maxillary central incisor through single-tooth osteotomy by using interdental space regained from microimplant anchorage.

When he was referred, infraocclusion of the maxillary right first molar was reported and it did not respond to orthodontic forced eruption. Diagnostic methods Clinical examination and X-ray are the main diagnostic methods for detecting ankylosis. 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.

In this context, the CBCT imaging allows identified with high accuracy all root surfaces affected dentap 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.
In the present case report, the close anquilosix 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. Occasionally, dental ankylosis may be sental with fifth finger clinodactyly. The disorder may result in loss of the retained molar and anquilosls 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.
Although there is no cement union to the alveolar bone in these cases, they present clinical features very similar to ankylosis. Dental ankylosis is a rare disorder characterized by the fusion of the tooth to the bone, preventing both eruption and orthodontic movement.

Orthodontic treatment of severe anterior open bite and alveolar bone defect complicated by an ankylosed maxillary central incisor: In such cases, the tooth may erupt partially, becoming relatively submerged or may not erupt Frazier-Bowers et al. Diagnosis of ankylosis in permanent incisors by expert ratings, Periotest and digital sound wave analysis.
An atypical presentation of mechanical failure of eruption of a mandibular permanent molar: CBCT is therefore an important diagnostic tool for examination and treatment planning Balajisafe for professionals and patients as well.

Familial occurrence has been shown in several families. Management dentl 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.
Besides, percussion clinical tests and metallic sound produced are only reliable in about one-third of the cases Cohen-Levy et al. The primary failure of the eruption mainly affects the posterior teeth Rhoads 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.
Impaction and retention of second molars: Also, it is not possible to visualize the root bifurcation area Silva. A retrospective followup study.
