2015年1月12日 · Cone-beam computed tomographic (CBCT) imaging is an advanced imaging modality that provides excellent visualization of the dental hard tissues and osseous structures in three dimensions. CBCT imaging has become widely used over the last decade because it has multiple applications in dentomaxillofacial diagnosis.

Objectives: The use of cone beam computed tomography (CBCT), to observe through retrospective study the alterations in the nasal airway following rapid maxillary expansion (RME) of...

Conventional CT equipment using a fan shaped X ray beam captures a series of axial plane slices or from a continuous spiral motion over the axial plane. A CBCT machine, on the other hand, uses a cone-shaped beam and a reciprocating solidstate flat panel detector, which rotates once around the patient , 180-360 degrees, covering the defined ...

2020年6月14日 · CBCT has applications in dentistry for endodontics, oral surgery, orthodontics, implants and more. It provides multiplanar views in the axial, sagittal, and coronal planes. Compared to medical CT, CBCT has a lower cost, lower radiation dose, faster scan time, and ability to image both jaws simultaneously.

2023年4月19日 · This technique allows dentists to obtain 2D reconstructed images in all planes and 3D reconstructions with minimal exposure to X-radiation. The dental CBCT technology is specifically designed to produce high-quality images of the teeth, jaws, and face by capturing tomographic images from different angles.

Cone beam computed tomography (CBCT) is a radiographic imaging method that allows accurate, three-dimensional (3D) imaging of hard tissue structures. CBCT is the most significant among the medical diagnostic imaging modalities that have emerged recently.

Objective This study aimed to evaluate the reproducibility of nine reference planes used in orientation of as-received cone-beam computed tomography (CBCT) images in all three dimensions. Materials and Methods The study was conducted on CBCT images of 15 adult sub-jects (mean age 21.2 ± 5.8 years).

The small field-of-view, high-resolution Cone Beam Computed volumetric Tomography (CBCT) unit produces three-dimensional radiographic images of the area in question. The Kodak 9000 3D system was designed to facilitate better patient care by providing more accurate and dependable treatment planning capabilities at a reduced patient dose.

Most dental CBCT systems use a fixed C-arm (i.e. a set-up in which X-ray tube and detector are connected using a rotatable, C-shaped arm), which usually rotates in the horizontal plane, allowing for seated and/or standing patient positioning . To position the FOV according to the region of interest (ROI), limited translation of the C-arm is ...

CBCT scan images were used to characterize the detailed bone thickness, absorbing height, and position of maxillary molar as well as their associated conditions.
