But the diagnostic accuracy is greatly reduced due to the low sensitivity for bony changes of the condyle and also a low reliability and accuracy of the temporal component. Abstract Since its introduction into dentistry in , CBCT has become increasingly utilized for orthodontic diagnosis, treatment planning and research. Change in condylar and mandibula morphology in juvenile idiopathic arthritis: Orthod Craniofac Res ; 6: The clinical effects that increased pharyngeal airway volume from these procedures has on respiratory function have not yet been determined. It is likely that as the field advances and more evidence of the efficacy of CBCT emerges, its applications in orthodontics will increase or be modified, which will enable clinicians to realize the ultimate goal of increased treatment efficiency or outcomes or both in many more clinical scenarios than currently possible.

Orthod Craniofac Res ; 7: This thesis has assessed medical, technical and health-related aspects of otosclerosis from a long-term perspective. Several of these studies show that CBCT provides clinically relevant information and novel 3D research data. This suggests that the effects of palatal expansion do not extend far enough posteriorly to significantly improve breathing in OSA patients but may be beneficial for patients with mild respiratory problems owing to nasal constriction. Currently, there is no evidence that detection of moderate-to-severe EARR differs between 2D and CBCT radiography or that its discovery by CBCT during treatment would lead to a different treatment decision—typically entailing stopping the treatment at least temporarily—than if detected by 2D radiography.

These are, however, plagued by the numerous superimpositions of the adjacent structures which make visualization cumbersome.

CBCT offers important information and finer details in treatment planning of supernumerary teeth. Clin Oral Implants Res ; TADs are often used to provide a stable anchor for the application of orthodontic forces. Semin Orthod ; Vertical bone volume in the paramedian palate cbt adolescents: J Clin Pediatr Dent ; Alveolar boundary conditions Alveolar boundary conditions are the depth, height and morphology of alveolar bone relative to tooth root dimensions, angulation and spatial position.


Orthod Craniofac Res ; 7: Clin Oral Investig ; Clinical recommendations regarding use of cone beam computed tomography in orthodontics. Indeed the findings of the systematic reviews 13 — 15 suggest that these 2D radiographs should also only be taken when they are expected to provide additional information that could aid in diagnosis or treatment planning or for assessing progress or complications during treatment.

The second method, called iterative closest point analysis determines the shortest distances between structures in two superimposed 3D images.

TMJ imaging by CBCT: Current scenario

Cone beam computed tomography, temporomandibular joint disorder, temporomandibular joint imaging. This has enabled orthodontists and researchers in the field to overcome the substantial limitations of 2D radiographs, including magnification, geometric distortion, superimposed structures and inconsistent head position.

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. Three-dimensional 3D airway visualization in the lateral athree-quarter b and frontal c views.

Also a hierarchical model ropic the efficiency of an imaging technique has been described in six-levels by Fryback and Thornbury. Moreover, since orthognathic surgery and craniofacial surgery are outside the scope of this review, these topics are not discussed.


Three-dimensional interpretation of periodontal lesions and remodeling during orthodontic treatment.


Magnetic resonance imaging of the temporomandibular topiv in patients with skeletal open bite and subjects with no dentofacial abnormalities. All three levels of indicators require a careful consideration of the benefit-to-risk analyses prior to undertaking CBCT. From the perspective of utility of CBCT as a diagnostic and treatment planning tool for transverse corrections, recent attempts have been made to understand if sutural maturation could help predict the relative magnitudes of skeletal vs dental expansion expected in patients undergoing RME with inconclusive findings.

Specifically, CBCT has been used to address two questions related to RME treatment, namely how expansion forces affect different regions of the maxilla and the effect of age on the relative magnitude of skeletal expansion vs dental tipping.
