At the office of Crowns Now Family Dentistry, we rely on modern imaging to make clearer, more confident clinical decisions. Cone-beam computed tomography (CBCT) gives our clinicians three-dimensional views of dental anatomy that conventional X-rays simply cannot provide. Those 3D images help us see relationships between teeth, bone, nerves, and sinuses with precision, which leads to more predictable treatment planning and better outcomes.
CBCT is not a replacement for routine X-rays; it’s a complementary diagnostic tool used when a higher level of detail is needed. Because the scan captures volumetric data in a single rotation, clinicians can examine exact dimensions, cross-sections, and spatial relationships without distortion. The result is a concise, information-rich dataset that supports procedures from implant placement to complex restorative and surgical planning.
Cone-beam computed tomography produces a three-dimensional image by rotating a cone-shaped X-ray beam around the patient’s head. Unlike traditional two-dimensional radiographs, CBCT renders depth and spatial orientation, allowing clinicians to visualize structures in axial, sagittal, and coronal planes. This means clinicians can assess bone height and width, root positions, and the proximity of anatomical landmarks with much greater accuracy.
The clarity of CBCT images is particularly valuable when anatomy is complex or when pathology may be hidden behind overlapping structures on a standard X-ray. Small cysts, root fractures, impacted teeth, and the course of the mandibular nerve are common findings that can change treatment strategy. Being able to examine these elements in 3D reduces uncertainty and supports decisions grounded in objective evidence.
Clinicians can also manipulate the data after the scan: measuring distances, evaluating bone quality, and creating cross-sectional slices at any angle. Those capabilities turn the CBCT dataset into a working map that informs diagnosis, risk assessment, and step-by-step treatment planning across a wide range of dental specialties.
CBCT has broad applications because it reveals relationships between hard tissues that are hard to appreciate otherwise. In endodontics, for example, CBCT can uncover hidden canals, apical pathology, or vertical root fractures that elude conventional radiographs. For periodontal or orthodontic assessment, it shows bone defects and tooth angulation in three dimensions, which helps determine the most appropriate therapeutic approach.
When evaluating oral pathology, CBCT helps localize lesions and assess their extent relative to adjacent structures. This information can be critical for timely referral, biopsy planning, or monitoring healing after treatment. The ability to identify anatomic variants — such as an extra canal, a bifid mandibular canal, or an unusual sinus anatomy — reduces intraoperative surprises and improves procedural safety.
Because the dataset is digital and shareable, multidisciplinary collaboration becomes easier. Specialists, lab technicians, and referring providers can review the same images to arrive at a coordinated plan. That shared access speeds communication and ensures everyone involved in a patient's care is working from the same objective information.
Implant dentistry relies on precise measurements and careful assessment of available bone. CBCT provides the dimensional accuracy needed to determine implant length, diameter, and ideal angulation while avoiding critical structures such as the inferior alveolar nerve and the maxillary sinus. This reduces the risk of complications and increases the likelihood of long-term implant success.
The volumetric data from a CBCT scan can be imported into implant planning software to simulate implant placement and fabricate surgical guides. These guides translate virtual plans to the clinical setting with high fidelity, allowing for controlled, minimally invasive placement and consistent prosthetic outcomes. In cases that require bone grafting or sinus lifts, CBCT also helps quantify the defect and plan graft dimensions precisely.
Surgeons and restorative teams benefit from being able to preview the final prosthetic outcome and ensure the implant position supports predictable esthetics and function. This anticipatory planning, supported by accurate 3D imaging, shortens procedure time and helps set realistic expectations for rehabilitation.
Patient safety is a core consideration with any imaging modality. Modern dental CBCT units are designed to provide clinically useful information with radiation doses that are generally lower than those associated with medical CT scans, especially when imaging fields are limited to the area of interest. Clinicians select the smallest field of view and the lowest exposure settings consistent with diagnostic needs to follow the ALARA principle — keeping exposure as low as reasonably achievable.
Not every dental situation requires CBCT. Its use is justified when the additional information will alter diagnosis or treatment. Before recommending a scan, the care team evaluates the clinical question and considers alternative imaging options. For routine restorative checks and simple screenings, traditional periapical or panoramic radiographs often remain the first step.
When a CBCT scan is recommended, staff take steps to make the experience comfortable and efficient: proper positioning, clear instructions, and brief scanning times. The technology captures the necessary data in a matter of seconds, and because no contrast agents are required, the procedure is straightforward for most patients.
Preparation for a CBCT appointment is minimal. Patients are typically asked to remove metal accessories and wear a stable, comfortable posture during the scan. For some cases, specific bite positions or the use of a positioning device may be necessary to capture the area of interest accurately. The scan itself usually takes only a brief moment, after which the clinician reviews the images.
Interpreting CBCT data requires clinical training and familiarity with volumetric imaging. Our team examines multiple views and uses measurement tools to evaluate bone volumes, tooth relationships, and soft-tissue boundaries where visible. Findings that require further evaluation are documented and, when necessary, discussed with appropriate specialists to determine the optimal course of care.
The information gathered from CBCT is used directly in treatment planning and patient education. Clinicians can show cross-sectional views, highlight concerns, and explain how proposed treatments address specific anatomical features. This visual clarity helps patients understand the rationale behind recommendations and participate in informed decision-making.
In summary, CBCT is a powerful diagnostic tool that brings three-dimensional insight to complex dental problems. When used thoughtfully, it improves accuracy, informs safer treatment, and supports more predictable outcomes.

Cone-beam computed tomography, commonly called CBCT, is a three-dimensional imaging technique designed for dental and maxillofacial evaluation. It uses a cone-shaped X-ray beam that rotates around the head to capture volumetric data in a single scan. The resulting dataset can be reconstructed into axial, sagittal, and coronal views for detailed assessment.
Unlike standard two-dimensional radiographs, CBCT reveals depth and spatial relationships among teeth, bone, nerves, and sinuses that are often obscured on periapical or panoramic images. These advantages make CBCT especially useful when clinicians need precise measurements or to visualize complex anatomy. At the office of Crowns Now Family Dentistry, we use CBCT selectively to improve diagnostic confidence and treatment planning.
A CBCT scan is recommended when the expected imaging information will affect diagnosis or change treatment decisions. Typical indications include implant planning, evaluation of impacted or ectopic teeth, assessment of suspected root fractures, and investigation of persistent pain or pathology that is unclear on conventional films. Clinicians also use CBCT for complex endodontic cases, assessment of sinus anatomy, and pre-surgical planning for extractions or bone grafting.
CBCT is not a routine substitute for periapical or panoramic radiographs and is used when three-dimensional detail is necessary. Before ordering a scan, the dental team evaluates the clinical question and chooses the smallest field of view and exposure settings that meet diagnostic needs. This targeted approach ensures CBCT adds meaningful information without unnecessary imaging.
CBCT provides precise measurements of bone height, width, and angulation, allowing clinicians to select appropriate implant dimensions and ideal positioning. The scan visualizes critical structures such as the inferior alveolar nerve and maxillary sinus, helping to avoid intraoperative complications. Volumetric data also allows assessment of existing bone quality and the extent of defects that may require augmentation.
Imported CBCT datasets can be used with implant planning software to simulate placement and design surgical guides that translate virtual plans to the clinical setting. Guided surgery increases placement accuracy, supports minimally invasive approaches, and helps coordinate restorative and surgical teams for predictable outcomes. This anticipatory planning reduces surprises during surgery and improves long-term prosthetic function.
Preparation for a CBCT scan is minimal: patients remove metal accessories and follow brief positioning instructions to ensure stability during the scan. Most CBCT units capture the required volume in a single rotation that takes only a few seconds, so the procedure is quick and noninvasive. Staff will explain the process, confirm the field of view, and help the patient feel comfortable before starting.
No contrast agents or injections are required for routine dental CBCT imaging, and the patient remains fully awake throughout the brief scan. After acquisition, clinicians review multiplanar views and measurement tools to confirm that the images address the clinical question. If further interpretation is needed, the images can be shared with specialists for collaborative planning.
Modern dental CBCT units are engineered to deliver clinically useful images with radiation doses that are generally lower than those of medical CT scans for similar anatomical regions. Clinicians adhere to the ALARA principle, selecting the smallest field of view and lowest exposure parameters that satisfy diagnostic requirements. Justification for a scan is based on the likelihood that the additional information will influence care, which helps limit unnecessary exposure.
Radiation risk is always considered in context, and for many dental indications the diagnostic benefit of CBCT outweighs its low risks when used appropriately. Children and pregnant patients require special consideration, and clinicians will discuss alternatives or defer imaging when appropriate. If a scan is recommended, staff take steps to optimize protection and minimize dose while ensuring sufficient image quality.
Interpreting CBCT data requires training in volumetric imaging and an understanding of anatomy across multiple planes. Clinicians examine axial, sagittal, and coronal reconstructions, create cross-sectional slices, and use measurement tools to quantify distances and volumes. This detailed analysis enables accurate diagnosis, risk assessment, and step-by-step treatment planning tailored to the patient’s anatomy.
Findings from CBCT can change clinical decisions by revealing pathology or anatomic relationships not visible on two-dimensional films. When unusual or complex findings are identified, the imaging dataset can be shared with specialists or used to plan biopsies, referrals, or additional interventions. Clear visualization also improves patient education by allowing clinicians to demonstrate concerns and explain recommended treatments using objective images.
Yes. CBCT often reveals issues that overlap or hide behind structures on conventional radiographs, such as small cysts, vertical root fractures, and accessory canals. Because CBCT captures volumetric information, clinicians can inspect anatomy from any angle and avoid misinterpretation caused by superimposition. This capability is particularly useful in endodontics, oral pathology, and cases with atypical symptoms.
Detecting these hidden problems can alter treatment pathways, from changing the approach to root canal therapy to identifying the need for surgical intervention. However, detection depends on image resolution and the selected field of view, so clinicians match imaging parameters to the diagnostic task. Appropriate use of CBCT maximizes diagnostic yield while minimizing unnecessary imaging.
CBCT has limitations including lower soft-tissue contrast compared with medical CT and variable resolution that depends on unit settings and field of view. It is not ideal for detailed evaluation of soft-tissue lesions or when higher contrast resolution is required for medical diagnosis. Metal artifacts from restorations can degrade image quality in the region of interest and must be considered when interpreting scans.
For routine screenings, periapical and panoramic radiographs remain appropriate first-line tools because they are quick, lower dose, and often sufficient for common assessments. When soft-tissue characterization or broader medical evaluation is necessary, referral for a medical CT or MRI may be indicated. Clinicians weigh these factors and choose the modality most likely to provide the information needed for safe, effective care.
CBCT datasets are digital and easily shareable, allowing surgeons, restorative dentists, orthodontists, and lab technicians to review the same objective images. Shared access to volumetric data promotes coordinated treatment plans, reduces miscommunication, and streamlines surgical and prosthetic workflows. Laboratories can use CBCT-derived measurements and digital files to fabricate custom guides, provisional restorations, or prosthetic components with greater precision.
This collaborative approach shortens treatment timelines by aligning surgical placement with restorative goals and by enabling preoperative fabrication of key components. When necessary, imaging can be discussed in multidisciplinary meetings or forwarded to outside specialists to ensure consensus on complex cases. The result is more predictable care and clearer expectations for both clinicians and patients.
At our offices, CBCT is integrated into diagnostic and treatment workflows when three-dimensional detail will influence patient care and improve safety. We select targeted fields of view and collaborate across specialties to plan implants, complex restorations, and surgical procedures with greater predictability. The imaging datasets also support patient education by allowing clinicians to illustrate findings and explain treatment options in a clear, visual way.
By combining volumetric imaging with clinical examination and specialist input when appropriate, we aim to reduce intraoperative surprises and enhance long-term results. CBCT helps the team anticipate anatomical challenges, plan conservative approaches, and deliver care that balances function, esthetics, and safety. Patients benefit from more informed decisions and transparent explanations grounded in objective imaging.
