3D Cone Beam
Winston-Salem, NC
At Gibson & Bartholomew Restorative and Esthetic Dentistry, we use the most advanced diagnostic tools available to ensure accurate, personalized care for every patient. One of the most important technologies in modern dentistry is 3D cone beam computed tomography, commonly called CBCT or cone beam CT scanning. This imaging system gives our team a complete, three-dimensional view of your teeth, jaw, nerves, and surrounding bone, details that simply cannot be captured with a traditional flat X-ray. When we can see your full anatomy before beginning treatment, every decision we make is better informed, and every procedure we perform is more precise.
What Is a 3D Cone Beam CT Scanner?
A cone beam CT scanner is a specialized imaging device designed specifically for dental and maxillofacial use. Unlike the large CT scanners found in hospitals, a cone beam unit is compact, emits significantly less radiation, and is optimized to capture the structures of the head and neck in extraordinary detail. The scanner uses a cone-shaped beam of X-ray energy that rotates around the patient's head in a single pass, typically completing the full rotation in 20 to 40 seconds. During that brief window, it collects hundreds of individual images from multiple angles and combines them into a single, continuous three-dimensional model.
The result is a highly detailed digital rendering of your teeth, roots, jawbone, temporomandibular joints, sinuses, nerve canals, and surrounding tissue. Our team can rotate this model in any direction, zoom in on specific structures, isolate individual layers, and take precise measurements, all before a single instrument touches your mouth. This capability changes the nature of treatment planning entirely.
How Cone Beam Imaging Supports Diagnosis
Many dental conditions are difficult or impossible to detect using standard two-dimensional X-rays. Flat images compress overlapping structures onto a single plane, which means important details can be hidden behind other anatomy. Cone beam CT removes that limitation by giving us a view of each structure in full three-dimensional context.
Conditions we can evaluate more thoroughly with CBCT imaging include bone loss around teeth and implants, infections or abscesses that extend into the jaw, cysts or benign tumors developing within bone, early signs of pathology that would not yet appear on a standard radiograph, and structural abnormalities of the jaw joint. Detecting these issues earlier and with greater accuracy leads to faster treatment, less invasive intervention, and better long-term results for our patients.
Procedures and Treatments That Rely on Cone Beam Technology
Cone beam CT is not limited to diagnosis. It plays an active role in planning and executing a wide range of dental procedures at Gibson & Bartholomew Restorative and Esthetic Dentistry. Several procedures can benefit from this technology.
Dental Implant Placement
Before placing a dental implant, we use CBCT imaging to measure the exact height, width, and density of available bone, identify the location of the inferior alveolar nerve and sinus floor, and confirm that the proposed implant site can support a stable, long-term restoration. This level of planning reduces surgical risk and supports more predictable outcomes.
Bone Grafting
When a patient does not have sufficient bone volume to support an implant, grafting is often required first. Cone beam imaging allows us to assess the defect with precision and determine the appropriate volume and type of graft material needed before the procedure begins.
Wisdom Tooth and Complex Extractions
Impacted teeth, particularly lower wisdom teeth, often sit in close proximity to the inferior alveolar nerve. CBCT imaging shows us exactly how the roots are positioned relative to that nerve, allowing us to plan the extraction approach in a way that minimizes risk.
Orthodontic Treatment Planning
For patients beginning orthodontic treatment, cone beam imaging reveals unerupted teeth, skeletal asymmetries, root angulations, and jaw development patterns that influence how treatment is structured, whether that involves braces, clear aligners, or a combination approach.
Temporomandibular Joint (TMJ) Evaluation
Standard X-rays provide limited information about the jaw joint. CBCT gives us a detailed, three-dimensional view of the condyle and surrounding structures, which is critical when evaluating patients with chronic jaw pain, clicking, locking, or limited range of motion.
Endodontic Treatment
When a tooth requires a root canal, especially a complex one involving curved or unusually narrow canals, cone beam imaging helps us map the internal anatomy of the tooth in advance. This preparation reduces the risk of complications and improves the accuracy of treatment.
Sleep Apnea and Oral Appliance Therapy
For patients being evaluated for obstructive sleep apnea or snoring, cone beam CT provides a three-dimensional view of the upper airway, tongue position, and soft tissue volume, information that supports more accurate appliance design and positioning.
Surgical and Pre-Prosthetic Planning
Any procedure involving jaw surgery, bone recontouring, or preparation for a full-arch restoration benefits from the detailed anatomical data that cone beam imaging provides.
What to Expect During a CBCT Scan
The scanning process is simple and non-invasive. You will be positioned standing or seated within the unit, and the scanner will rotate around your head without making contact. There is nothing to bite down on, no discomfort, and no extended waiting. The entire scan is complete in under a minute, and the resulting images are available for review almost immediately. We will walk you through what the images show and explain how they inform your treatment plan.
A Clearer Picture Leads to Better Care
The value of cone beam CT imaging comes down to one thing: reducing uncertainty. When our team can see your anatomy in three dimensions before performing a procedure, we are not estimating, we are working from a complete and accurate picture. That translates to more precise treatment, fewer surprises during surgery, and outcomes you can count on.
At Gibson & Bartholomew Restorative and Esthetic Dentistry, our investment in this technology reflects our commitment to providing care that is thorough, safe, and built around your individual needs.
