J Orofac Orthop ; Does bone mineral density influence the primary stability of dental implants? Evaluating the mandible with cone-beam computed tomography. Clinical recommendations regarding use of cone beam computed tomography in orthodontics. Sufficient lead time allows the graft to mature and gives the orthodontist sufficient time for arch development to better support the canine as it erupts into the arch.

This enhanced information derived from CBCT scans compared with 2D images may be critical in changing treatment plans, including the option to extract a resorbed lateral incisor rather than a premolar in an extraction case. Craniofacial and upper airway morphology in pediatric sleep-disordered breathing: Limited opening or excursive movements, joint pain and joint sounds are indicators of various TMJ pathologies, including osteoarthritis, rheumatoid arthritis, idiopathic condylar resorption and other less common TMJ disorders. Nevertheless, it is now well accepted that CBCT in combination with computerized treatment planning and 3D printed wafers splints is a powerful tool for treating these cases. Alveolar bone thickness and lower incisor position in skeletal Class I and Class II malocclusions assessed with cone-beam computed tomography. The effects of sutural and cervical vertebral maturation on dentoalveolar versus skeletal responses to rapid maxillary expansion.
Skeletal effects to the maxilla after rapid maxillary expansion assessed with cone-beam computed tomography. Indeed, of the many types of clinical situations being presented to the orthodontist, impacted teeth are ones in which CBCT has been most shown to improve diagnosis and contribute to modifications in treatment planning in a significant number of subjects. While 3D CBCT images are most often used to assess skeletal contributions to malocclusion, researchers are now investigating the use of these images to assess dental relationships in orthodontic patients.
Ever since, several CBCT systems have evolved that have been extensively used in the field of medical clinical imaging. Kapila S, editor;ed.

Conclusions Since its introduction into dentistry inCBCT has become an increasingly important source of 3D volumetric information in clinical orthodontics. Several radiographic methods are used to assess the TMJ, an area that is difficult to be imaged due to factors like superimposition of adjacent structures and morphological variations.

Eur J Orthod ; Mandibular incisors, alveolar bone, and symphysis after orthodontic treatment. J Oral Rehabil ; One of the key advantages of CBCT over 2D radiography is its ability to provide 3D volumetric, surface and sectional information about the craniofacial structures.

Labio-lingual root control of lower anterior teeth and canines obtained by active and passive self-ligating cvct. The utilization of CBCT for these purposes toic been facilitated by the relative advantages of three-dimensional 3D over two-dimensional radiography. Community Dent Health ; Orthodontic research and findings using CBCT A large proportion of published original CBCT studies have focused on craniofacial and airway morphometric analyses in health and disease; CBCT use in analysing treatment outcomes; and evidence-based indications, uses and efficacy of CBCT in diagnosis and treatment planning, that are summarised below.
Sufficient lead time allows the graft to mature and gives the orthodontist sufficient time for arch development to better support the canine as it erupts into the arch. Quantification of condylar resorption in temporomandibular joint osteoarthritis. Assessment of root position and morphology by cone beam computed tomography. This finding highlights the efficacy of the 3D rendering capacity of CBCT for accurate diagnosis of both EARR and other previously uncharacterized types of root resorption.
Craniofacial and upper airway morphology in pediatric sleep-disordered breathing: Thess 3D craniofacial and dental morphometrics is important for defining normal and abnormal 3D anatomy of structures with a potential for longer-term utility in diagnosis and treatment planning. Complex etiologic factors like trauma, emotional stress, orthopaedic instability, muscular hyperactivity, inflammatory and degenerative diseases, which compromise the equilibrium thesiz the temporomandibular joint TMJhave been implicated in the development of temporomandibular joint disorders TMD.
Despite many suggested indications of CBCT, scientific evidence that its utilization improves diagnosis and treatment plans or outcomes has only recently begun to emerge for some of these applications.
