Management of a severely submerged primary molar: An atypical presentation of mechanical failure of eruption of a mandibular permanent molar: Studies on diagnosis of ankylosis using CT are limited Kitai et al. Dentoalveolar ankylosis is an anomaly of dental eruption, caused by mechanical failure of eruption Frazier-Bowers et al. Ankylosis is defined as the anatomical fusion of cementum with alveolar bone Loriato et al. Indications of cone beam CT in head and neck imaging.
Diagnostic methods Clinical examination and X-ray are the main diagnostic methods for detecting ankylosis. On the other hand, if the infraocclusion is severe, the treatment is more complex and has the following options: Three-dimensional evaluation of a rare case with multiple impacted teeth using CT. Whereas computed tomography CT is considered superior to radiography Kirziolu et al.
It is worth mentioning that surgical extraction often causes bone defects in the alveolar area affected by ankylosis Lim et al. The major characteristic of a secondarily retained molar is infraocclusion that may result in malocclusion. 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. Check this box if you wish to receive a copy of your message. As observed in the case reported, the more evident clinical sign of ankylosis is the presence of infraocclusion Cohen-Levy et al.
Impaction and retention of second molars: Ankylosis of teeth Prevalence: In a growing child, an ankylosed tooth appears to ‘submerge’ as adjacent unaffected teeth and alveolar bone continue their normal pattern of growth occlusally. Moreover, radiographic examination is also inaccurate Kirziolu et al. Use of bone extraction tool. Use of dentomaxillofacial anquolosis beam computed tomography in dentistry. Also, it is not possible to visualize the root bifurcation area Silva.
Treatment of ankylosed mandibular first permanent molar. Besides, the CBCT exam confirmed the presence of ankylosis in the roots of the teeth.
aqnuilosis Treatment of ankylosis of the mandibular first molar with orthodontic traction immediately after surgical luxation. For all other comments, please send your remarks via contact us. 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 anquiilosis details that could not be visualized in conventional radiographic techniques because of their two-dimensional nature and overlapping structures.
In order to be acknowledged with the subject, we made a research in the PubMed database, using the following key words: After eruption, it halts any adaptive changes.
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. Anquilosis del Primer Molar Permanente: Specialised Social Services Eurordis directory. Permanent molars are less frequently affected than deciduous molars.

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.
Clinical description The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone.
The ethics committee on human research exempted this study approval since only CBCT images would be disclosed without the possibility of patient identification. 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. Health care resources for this disease Expert centres 51 Diagnostic tests 0 Patient organisations 15 Orphan drug s 0. Traumatic lesions are considered the main factor for development of ankylosis Atobe et al.
Varying numbers of teeth may be affected. Trauma, inflammation or infection may play a causative role.
Terminology and manifestations of eruption disturbances. The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Hence, ankylosis diagnosis may occur incidentally, when the patient undergoes an orthodontic treatment and the tooth does not respond to orthodontic movement Takahashi et al. Orthodontic treatment of an ankylosed maxillary central incisor through single-tooth osteotomy by using interdental space regained from microimplant anchorage.
Diagnosis by Cone Beam Computed Tomography. 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.
In the initial stages, the primary failure of eruption and ankylosis may have similar clinical presentations Frazier-Bowers et al. In the impaction, the eruption is impaired due to the presence of a physical barrier or due to the ectopic position of the tooth. However, unlike the primary failure, normal eruption of adjacent teeth was observed. Radiographic testing enables assessing only proximal regions of possibly affected roots.

With the lack of accessibility of genetic tests in dental offices to confirm the occurrence of primary failure Rhoads et al. 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, ankylosis early diagnosis is difficult, for in the beginning areas absence periodontal ligament are small and the tooth still presents mobility Dentak et al.
