GXCB-500™: Detailed 3-D Information for Informed Decisions
3-D cone beam imaging allows practitioners to gain the most radiographic knowledge about the patient’s anatomy to facilitate diagnostics and treatment-planning decisions.
The Gendex GXCB-500™ (Figure 1) digitally replicates mouth and jaw anatomy with distortion-free, 360°, 3-dimensional (3-D) scans that display vividly on a computer monitor. These images allow for full interactive investigation and planning, as well as excellent patient education.
This affordable system provides a medium field of view. Dentists can capture one or both arches (Figure 2)—the areas of interest for most general practitioners, periodontists, and prosthodontists—for tasks such as implant and surgical planning and endodontic evaluation. Additionally, the system features an Extended Diameter Scan mode (EDS) that expands to capture the condyle area for temporomandibular joint (TMJ) analysis (Figure 3).
The GXCB-500 offers a traditional 2-D (2-D) pan feature with its Amorphous Silicon single-sensor design that is activated by one selection within the software; no need for a sensor change-out. This additional 2-D option, along with the GXCB-500’s small footprint, allows the dentist to trade out his or her existing pan while still retaining the freedom to choose the best radiographic option for the patient.
The patient is seated for a natural jaw relation and for greater stability during scanning (Figure 4). Laser guides provide quick patient alignment. A preview feature, “Scout Shot,” offers even greater guidance that could save the patient additional radiation should the clinician seek a specific area that the operator must provide with additional positioning adjustments.
Although dentists have the ability to choose varying resolutions, the most commonly captured scan takes only 8.9 seconds. As with the seated position, less exposure translates into better image quality because of the reduced chance of movement.
Reconstruction takes less than 20 seconds, allowing the dentist to begin diagnosis and planning immediately.
The i-CATVision™ software offers many views, including panoramic, lateral, sagittal, coronal, axial, and more, along with 360º rotation and cross-sectional slicing (Figure 5; Figure 6; Figure 7; Figure 8). It also features a 3-D rendering of the selected anatomy. The software also provides specialized screens and tools devoted to implant planning, TMJ evaluation, and airway analysis. Scan image data is easily exported in DICOM format for use in 3-D implant treatment planning software.
The GXCB-500 can give dentists more confidence in their ability to choose which procedures they want to perform and, just as important, those that they would rather refer to a specialist. The clinician can gain a real “teamwork” approach to patient care by freely sharing the scan and the i-CATVision™ software with colleagues.
