At the office of The Local Dentist in Bellingham, WA, we use advanced imaging tools to build treatment plans that are precise, predictable, and tailored to each patient’s anatomy. Cone-beam computed tomography (CBCT) gives us high-resolution, three-dimensional information that traditional two-dimensional films cannot provide — helping us see the full picture before treatment begins.
Our goal with CBCT is simple: reduce uncertainty. By combining detailed 3D imaging with clinical examination and digital workflow, we can make more informed decisions, minimize surprises during procedures, and deliver care that’s both gentle and effective.
CBCT produces volumetric images that let clinicians view teeth, bone, nerve pathways, sinuses, and soft-tissue outlines from any angle. Instead of a flattened image, you get a stack of slices or a 3D model that reveals the true spatial relationships inside the jaws — essential when small differences matter.
This depth of information helps identify root positions, bone contours, and anatomical variations that might be invisible on standard periapical or panoramic radiographs. It also improves the detection of pathologies such as cysts, fractures, and unusual root anatomy that can affect treatment choices.
Clinically, that means fewer unknowns. Whether planning a restoration, evaluating post-traumatic changes, or investigating unexplained symptoms, CBCT provides context — showing how structures interact rather than presenting isolated shadows on film.
One of the most transformative uses of CBCT is in implant dentistry and oral surgery. The scans allow us to measure bone volume, evaluate quality, and locate vital structures like the inferior alveolar nerve or maxillary sinus with millimeter accuracy. That information is indispensable when determining the ideal implant size, angle, and position.
When combined with digital planning software, CBCT data supports virtual implant placement and the fabrication of surgical guides that transfer the plan from the computer to the mouth. This reduces intraoperative guesswork and enhances the predictability of outcomes.
For complex surgical cases — impacted teeth, grafting procedures, or reconstruction after trauma — 3D imaging helps the clinical team anticipate challenges, select appropriate approaches, and communicate the plan clearly with patients and specialists.
Modern CBCT systems are designed with dose optimization in mind. Unlike older volumetric scanners, contemporary machines allow clinicians to limit the field of view and adjust exposure settings so that only the necessary anatomy is captured, following the ALARA (As Low As Reasonably Achievable) principle.
In practice this means a targeted scan for a localized problem rather than a full-face exposure. Smaller fields and shorter scan times reduce radiation while still delivering diagnostic detail. Our team evaluates the clinical need for every scan and selects the protocol that balances information gained with patient safety.
Pediatric and medically complex patients receive special consideration. We tailor exposure parameters and positioning to minimize dose while ensuring diagnostic quality, and we only recommend CBCT when it will change the course of treatment or add important diagnostic value.
CBCT supports a broad range of dental disciplines. Endodontists use volumetric imaging to visualize complex root canal anatomy and to locate missed canals or periapical pathology. Orthodontists rely on 3D data to evaluate tooth eruption, skeletal relationships, and airway volume when planning treatment.
Sleep medicine and airway assessment also benefit from CBCT. The scans can reveal constrictions, tongue posture, and the relationship between the jaws and airway space — information that helps when considering oral appliance therapy for obstructive sleep apnea.
Additionally, CBCT aids TMJ evaluation, assessment of facial asymmetries, and preoperative mapping for bone grafting or sinus lifts, making it a true cross-disciplinary tool that improves diagnosis and streamlines referrals when specialist input is needed.
A CBCT appointment is brief and straightforward. Patients sit or stand while the scanner rotates around the head for a matter of seconds; the entire procedure typically takes under a minute from positioning to image capture. There is no enclosed tube — most systems feel open and non-intimidating.
Preparation is minimal: we ask patients to remove metal objects that could interfere with image quality and to follow any simple instructions from the technician. The resulting images are available quickly and integrate directly with digital treatment-planning tools we use in the office.
After the scan, your clinician will review the images, explain the findings in plain terms, and outline how the information influences your treatment options. If needed, we coordinate with specialists using the same detailed datasets so everyone involved is working from the same precise information.
CBCT is a powerful diagnostic resource that helps our team plan safer, more predictable treatments while keeping patient comfort and safety at the forefront.

Cone-beam computed tomography (CBCT) is a specialized three-dimensional imaging technology that captures detailed views of the teeth, jaws, sinuses and adjacent structures. Unlike standard two-dimensional dental x-rays, CBCT acquires volumetric data using a rotating cone-shaped x-ray beam and a digital detector. The resulting high-resolution cross-sectional images can be reformatted in multiple planes for comprehensive evaluation.
CBCT reduces distortion and superimposition that can limit conventional films, enabling more accurate measurements and assessment of complex anatomy. This improved visualization supports diagnosis and treatment planning for surgical, endodontic and restorative procedures. CBCT is used as a diagnostic adjunct and is selected when three-dimensional information will change patient care.
CBCT provides critical information for implant planning by allowing precise assessment of bone volume, density and the spatial relationship of anatomical structures such as the inferior alveolar nerve and maxillary sinuses. Three-dimensional measurements from CBCT scans help clinicians determine optimal implant length, diameter and angulation before surgery. When combined with digital planning software, CBCT data can be used to design guided-surgery templates that transfer the virtual plan to the clinical setting.
Using CBCT for implant planning reduces guesswork and supports predictable placement, especially in complex cases or areas with limited bone. The 3D data may also reveal pathology or variations in anatomy that affect treatment choices. When indicated, CBCT enables a fully digital workflow from diagnosis to guided placement and prosthetic design.
Before ordering a scan, dentists evaluate whether CBCT will meaningfully influence diagnosis or treatment and consider alternatives when two-dimensional imaging is sufficient. Protective measures such as thyroid shielding or limiting the scanned area are used when appropriate. For vulnerable groups, including pregnant patients, imaging is only performed when clearly justified and after discussing risks and benefits with the patient.
Preparation for a CBCT scan is minimal and noninvasive; patients are typically asked to remove metal objects such as earrings, necklaces and removable dental appliances that could create artifacts. It helps to wear comfortable clothing and to inform the office about pregnancy, recent medical imaging or any implanted medical devices. Providing an accurate medical and dental history ensures the clinician can tailor the imaging protocol appropriately.
There is no need to fast or alter medications for a routine dental CBCT. The procedure is performed with the patient seated or standing and requires only that the patient remain still for the short acquisition time. After the scan, images are processed and reviewed by the clinician as part of the treatment planning conversation.
CBCT is valuable for detecting and evaluating a wide range of dental and maxillofacial conditions, including impacted or ectopic teeth, root fractures, periapical pathology, cysts and tumors. It is also useful for assessing temporomandibular joint anatomy, sinus disease that impacts dental care, and complex orthodontic or surgical cases. The three-dimensional perspective improves the ability to localize lesions and understand relationships among structures.
In endodontics, CBCT can reveal root canal anatomy and identify vertical root fractures that are difficult to see on two-dimensional films. CBCT is also used for airway assessment in sleep-disordered breathing evaluations and for planning orthognathic surgery. Clinicians weigh the diagnostic benefits against limitations such as reduced soft-tissue contrast when determining the appropriateness of CBCT.
The actual image acquisition with modern CBCT equipment is very brief, often lasting only a few seconds to under a minute, though total appointment time may be longer due to positioning and image processing. Patients are positioned in the unit and asked to remain still while the scanner rotates around the head to collect volumetric data. The procedure is painless, and no injections or anesthesia are required for the scan itself.
Once the scan is complete, images are reconstructed into three-dimensional datasets that clinicians can review on-screen and manipulate in different planes. This rapid turnaround allows the dentist to discuss findings and next steps during the same visit when appropriate. If additional interpretation is needed, scans can be shared securely with specialists or an oral and maxillofacial radiologist for consultation.
CBCT can provide useful anatomical information about the upper airway, craniofacial skeleton and soft-tissue relationships that contribute to obstructive sleep apnea and snoring. Three-dimensional airway measurements and visualization of the palate, tongue space and bony structures help clinicians understand anatomic contributors to obstruction. This information can complement clinical evaluation and sleep-study data when considering oral appliance therapy or surgical options.
While CBCT contributes important structural detail, treatment planning for sleep-disordered breathing also relies on clinical examination, patient symptoms and formal sleep testing when indicated. CBCT is one component of a multidisciplinary approach and is used selectively to inform device design, predict therapeutic effects and monitor anatomical changes over time.
CBCT scans are interpreted by trained dental clinicians who understand three-dimensional radiographic anatomy, and in complex cases the images may be reviewed by or co-interpreted with an oral and maxillofacial radiologist. Dentists receive training in CBCT interpretation and use standardized approaches to evaluate bone, teeth and surrounding structures for pathology or treatment planning. When radiographic findings are outside the scope of the treating clinician, referral for specialist review is common practice to ensure accurate diagnosis.
The Local Dentist reviews CBCT results with patients as part of a shared decision-making process, explaining what the images show and how they affect treatment options. Patients can expect a clear discussion of findings, clinical implications and recommended next steps following the imaging study. If additional expert consultation is needed, the practice coordinates that review and communicates the results to the patient.
CBCT has limitations, including lower soft-tissue contrast compared with medical CT and susceptibility to artifacts from metal restorations or motion, which can obscure details. The technology provides excellent bony and dental detail but may not replace other imaging modalities when soft-tissue evaluation is required. As with any x-ray procedure, there is exposure to ionizing radiation, so clinicians apply selection criteria and dose-reduction strategies to limit unnecessary scans.
Certain situations—such as routine screening without a specific clinical indication—do not justify CBCT imaging, and special consideration is given to pregnant patients and children to minimize exposure. By following evidence-based guidelines and using targeted fields of view, clinicians balance diagnostic benefit against potential risks. Clear communication about indications and alternatives helps patients make informed decisions about imaging.
The Local Dentist employs a modern CBCT system to obtain targeted, high-resolution three-dimensional images that support accurate diagnosis and precise treatment planning. These images assist clinical decision making across many specialties, including implantology, endodontics, oral surgery and airway assessment, by revealing anatomy that cannot be fully appreciated on two-dimensional films. Integrating CBCT into the diagnostic process helps reduce uncertainty and tailor interventions to each patient’s unique anatomy.
CBCT data are used in conjunction with clinical examination and other diagnostic tools to develop comprehensive, individualized treatment plans focused on whole-health outcomes. The practice emphasizes evidence-based imaging protocols, minimizing radiation exposure while maximizing diagnostic value. Patients are informed about the purpose of imaging and how the results guide safe, effective care.
