High-resolution small field scans are suitable for detecting missed canals, secondary signs of root fracture and perforations
Strongly indicated for the detection of root perforations. A high level of certainty regarding a potential root perforation can be acheived via CBCT. Of course, if a metal post is present in the root canal, image quality will be lower.
Strongly indicated for the detection of missed canals, primarily by studying the profile (shape) of roots from an axial (occlusal) perspective. You can tell from the root shape whether an additional unfilled canal is present in the mesiobuccal root of maxillary first molars, for example.
Variable results for the detection of non-displaced root fractures. The most reliable radiographic finding is the present of a long narrow pocket along a root surface. Often, beam hardening artifacts can mimic fractures, resulting in an incorrect diagnosis of a fracture where one isn't present.
Cone beam CT offers an unparalleled means of evaluating internal and external root resorption
Strongly indicated for the detection of external resorption by adjacent pathologic entities or impacted teeth
CBCT provides a clear visualization of impacted maxillary canines, supernumerary teeth, and wisdom teeth
Strongly indicated for the localization of impacted maxillary canines and for the evaluation of their effects on the roots of adjacent teeth
The evaluation of the extents of bony pathologic lesions and maxillary sinus lesions are improved with CBCT. Note that soft tissue lesions cannot be effectively assessed (e.g: tongue lesions)
Lesions that are confined to or have an effect on bone can be visualized via CBCT. Often, the extent of the entity and its effects on surrounding structures can be determined, but definitive diagnoses are usually obtained via histopathology.
The TMJs can be evaluated for signs of degenerative joint disease, and when coupled with a clinical exam, can provide an indication of the state of the articular disc
TMJ diseases such as degenerative joint disease can be identified by cone beam CT. However, the articular discs of the joints cannot be visualized directly with CBCT. Disc position must be inferred by the position of the condylar head and by clinical findings. Only an MRI can visualize the discs directly.
CBCT-guided implant planning can be as involved or as minimal as you want it to be: From bone measurements to CAD/CAM guided surgeries to digital platforms for prosthetically driven planning, and everything in-between.
CBCT scans are dimensionally accurate, allowing measurements of bone architecture in putative implant sites to be made.
Tooth-supported guides based on computer assisted planning can be fabricated in-house by a lab with the CoDiagnostix system. This guide is preferred for tooth supported cases at Canaray because it can be reliably seated with little to no adjustment. The most economical system for computer-guided surgery.
Mucosa and Bone-supported guides based on computer assisted planning are fabricated in Materialise's centralized facility in the USA. This system is preferred for mucosa or bone-supported guides because a bone-supported guide can be fabricated without an impression of the bone. Software conversions are required.
For Nobel implants only. A specially constructed radiographic guide is necessary to use this system. The clinician receives the scan data and plans the case independently.
