Having the most information possible is key to providing proper treatment for your patients. Cone beam computed tomography provides a detailed view of the mouth that includes precise tooth position, bone dimension and quality, TMJ disorders, and other dental conditions. Field of view (FOV) refers to the anatomical area that will be included in the 3D data volume. This is the area where the patient will receive radiation. Depending on the specific unit, the FOV may be small, medium, or large.
The ALARA Principles (As Low As Reasonably Achievable) are used to make decisions on which radiographic modality and field of view should be chosen for dental X-rays. This helps to limit the amount of radiation exposure for a patient to a level that is as low as possible while still obtaining high-quality images.
Area Captured by Medium Field of View Cone Beam
A medium FOV is typically used to capture one arch or both arches in an image that is 6-11 cm in height and up to 14 cm in width. This is the ideal size for evaluating the extent of a lesion or the status of the temporomandibular joint. Medium FOV cone beam systems are also ideal for implant planning cases, especially when using or creating surgical guides.
When both dental arches are scanned, extracted 2D panoramic renderings can often be derived from the data set in wider medium FOV cone beam systems. This enhances the dental diagnosis and streamlines the imaging process. Other medium FOV cone beam systems may include dedicated 2D panoramic capabilities.
Medium Field of View Cone Beam for Dental Implant Placement
Dental implant placement is one of the fastest-growing areas of dentistry. Typically, an 8 x 8 cm cone beam scan is used for this procedure, which makes medium field of view cone beam systems the ideal choice. When combined with implant planning software, implant cases can be planned faster and with more precision than ever before with dental cone beam imaging.
With using cone beam scans rather than 2D panoramic images, you can prevent implants that are non-parallel, too lingual, too buccal, too close together, or placed in sinuses or inadequate bone. CBCT scans can also allow you to see the details or an implant’s proximity to the nerve and sinus, as well as the width, depth, and height of the bone structure. This helps to prevent possible surgical complications and achieve better outcomes for your patients.
Medium Field of View Cone Beam for Third Molars and TMJ
Select medium FOV cone beam units can extend to a wider scan, such as 8 x 14 cm, so that you can view third molars and evaluate TMJ. When these scans are combined with 3D imaging software, you can view the anatomy from several different views, including sagittal, axial, or coronal planes. Oblique, curved-plane slicing or paging through the voxel layers will allow you to visualize the patient’s internal anatomy.
For TMJ cases, dentists can view the upper airway, mouth, and hyoid bone.
For impacted teeth, it’s important to evaluate the relationship between the dental structures, including adjacent teeth, the mandibular canal, fossae, sinuses, and alveolar ridge boundaries. With 2D imaging, the pathology of the impaction is not always visible. This includes supernumerary tooth or neoplasm, or pathology that is adjacent to or secondary to an impacted tooth, such as cysts, tumors, or inflammatory processes.
Limitations of Medium Field of View Cone Beam
Some medium FOV cone beam systems only extend to 8 cm wide, which may not capture the entire mandibular nerve path and all necessary TMJ structures. In these cases, a wider medium FOV may be a better choice for your practice. Renew Digital carries a wide variety of medium FOV cone beam units in varying widths to meet these needs.
No matter your practice needs or budget restrictions, Renew Digital can help you find the best medium field of view cone beam system to help with your dental implant and other treatment needs. Renew Digital has the widest selection of medium FOV cone beam units at the lowest possible price – often at a savings of 30-50% off the price of new dental cone beam machines.
