“…[9][10][11][12][13][14] Lack of details and superposition of images are the limitations associated with using conventional radiographs to determine the precise anatomic limits of the nasal cavity. 15 Moreover, the accuracy and quality of images obtained by cone-beam computed tomography have led the authors of recent research involving upper airway structures 5,15,16 to choose it as the preferred method.…”

Objective: Cone-beam computed tomography (CBCT) is a reliable method of assessing the oral cavity and upper airways. We conducted this study to examine the changes introduced by rapid maxillary expansion in the nasal cavity, nasopharynx, and oropharynx as seen with images obtained by CBCT. Materials and Methods: We evaluated 15 patients with maxillary width deficiency treated with RME. Patients were subjected to CBCT at the beginning of RME and after the retention period of 4 months. Results: The nasal cavity presented a significant transverse increase in the lower third, in the anterior (1.08 mm 6 0.15), medium (1.28 mm 6 0.15), and posterior regions (0.77 mm 6 0.12). No significant change occurred in the nasopharynx in volume (P 5 .11), median sagittal area (P 5 .33), or lower axial area (P 5 .29) resulting from the RME. A significant change was noted in the oropharynx in volume (P 5 .05), median sagittal area (P 5 .01), and lower axial area (P 5 .04) before and immediately after the RME. Conclusions: RME is able to increase the transverse width of the nasal cavity, but it does not have the same effect in the nasopharynx. Changes noted in the oropharynx may be due to the lack of a standardized position of the head and tongue at the time of image acquisition. (Angle Orthod. 2012;82:458-463.)

“…35,56 While all studies on rapid palatal expansion treatment demonstrated both dental and alveolar tipping, none found detrimental effects (such as dehiscences or fenestrations) to the alveolar bone supporting the posterior teeth. [57][58][59][60][61][62][63] CBCT images are clear enough to measure alveolar bone thickness to an accuracy of 0.6 mm. 64,65 In fact, one recent study suggested that CBCT images with a voxel size of 0.4 mm actually overestimate alveolar bone loss following rapid palatal expansion.…”

Cone beam computed tomography use in orthodontics

Cone beam computed tomography (CBCT) is widely used by orthodontists to obtain three‐dimensional (3‐D) images of their patients. This is of value as malocclusion results from discrepancies in three planes of space. This review tracks the use of CBCT in orthodontics, from its validation as an accurate and reliable tool, to its use in diagnosing and treatment planning, and in assessing treatment outcomes in orthodontics.
