The Power of 3D Imaging: How CBCT Enhances Your Dental Care

At Michael Colleran, DDS, precision and comfort are at the heart of every treatment plan. To support that commitment, Dr. Colleran uses an advanced 3D imaging technology called cone beam computed tomography, or CBCT. This innovative imaging system creates a detailed, three-dimensional view of your teeth, jawbone, and surrounding structures to offer a clearer picture than traditional X-rays alone. The result is more accurate diagnosis, more confident treatment planning, and a smoother patient experience from start to finish.

What Makes CBCT Different

CBCT is designed to capture a full 3D image of your oral and facial structures in a single scan. Unlike standard dental X-rays, which show only two-dimensional slices, CBCT imaging provides a complete view that can be rotated and analyzed from every angle. The technology uses a cone-shaped beam to take hundreds of digital images in seconds, compiling them into a precise 3D model.

This level of detail allows Dr. Colleran and his team to assess bone density, tooth position, nerve pathways, and sinus anatomy with remarkable clarity. The scan typically takes less than a minute, and because the system is digital, radiation exposure is generally lower than with conventional medical CT scans.

According to Dr. Colleran, “CBCT technology allows us to see the full picture of each patient’s oral health. It helps us plan procedures with accuracy and confidence, while keeping the patient’s safety and comfort in mind.”

How CBCT Is Used

CBCT is used for several surgical and non-surgical procedures that require clear imaging and especially accurate planning.

Dental Implants and Tooth Replacement

When planning for dental implants, precision is essential. CBCT imaging plays a crucial role in identifying the exact position, angle, and depth of the implant before surgery begins. By mapping the jawbone and neighboring structures in 3D, Dr. Colleran can evaluate bone quality and locate vital anatomical features such as nerves and sinus cavities.

This comprehensive view helps reduce the risk of complications and supports predictable, long-term outcomes for patients seeking to restore missing teeth. Whether replacing a single tooth or designing a full-arch restoration, CBCT imaging provides the insight needed to plan treatment with confidence and accuracy.

Root Canal Diagnosis and Endodontic Precision

CBCT imaging also supports advanced endodontic care by helping diagnose infections, cracks, and complex root canal anatomy that may be difficult to see on traditional X-rays. The ability to visualize the exact shape and length of each root canal can guide more precise treatment, which may support comfort and smoother healing for patients.

For patients who have persistent symptoms after a previous root canal or who present with challenging anatomy, CBCT offers a way to uncover hidden problems that might otherwise go unnoticed.

Wisdom Teeth and Surgical Planning

When wisdom teeth become impacted or crowd neighboring teeth, accurate imaging is key to safe surgical planning. CBCT imaging allows Dr. Colleran to visualize the position of each tooth in relation to the jawbone and nearby nerves. This helps determine whether removal is needed and allows for a more conservative, well-planned approach if surgery is required.

Because 3D imaging helps identify potential challenges before treatment begins, patients also benefit from a clear understanding of what to expect.

TMJ and Bite Analysis

For patients experiencing jaw discomfort, popping, or headaches related to temporomandibular joint (TMJ) concerns, CBCT imaging provides valuable insight into the structure and alignment of the joint. The technology captures detailed images of the bones and soft tissues that make up the TMJ, helping Dr. Colleran evaluate joint health and bite balance.

By identifying possible misalignments or joint changes, CBCT can support more targeted treatment planning for bite adjustments, oral appliances, or other therapies designed to reduce discomfort and support long-term joint function.

Orthodontics and Invisalign Planning

Precise imaging is also essential for orthodontic treatment, especially with clear aligners such as Invisalign®. CBCT scans help create accurate digital models of your teeth and bite, allowing for custom treatment plans that move teeth efficiently and predictably. The 3D images also show the relationship between the teeth, roots, and bone, giving a more complete view of how orthodontic forces will affect your smile.

With this data, Dr. Colleran can design a plan that supports both aesthetic and functional results while monitoring progress throughout treatment.

Sinus and Airway Evaluation

In addition to dental structures, CBCT scans can visualize the sinuses and airway spaces. This information can be particularly helpful for patients who experience chronic sinus issues, breathing difficulties, or symptoms related to sleep-disordered breathing. A clear view of these spaces can help guide referrals and coordinate care with medical professionals when needed.

By assessing how the airway relates to the jaw and palate, CBCT may help identify potential obstructions or anatomical factors that could influence oral health and overall well-being.

Bone Grafting and Oral Surgery

Detailed imaging supports precise planning when bone grafting or other surgical procedures are recommended. CBCT scans allow Dr. Colleran to measure bone volume and quality, evaluate potential graft sites, and determine the safest, most effective surgical approach. This is especially valuable when preparing for dental implants or other restorative treatments that depend on healthy bone structure for stability.

Before beginning any procedure, patients can review their 3D images with Dr. Colleran to better understand their treatment options and visualize the process ahead.

What Patients Can Expect With CBCT

A CBCT scan is quick, comfortable, and noninvasive. During the scan, you’ll stand or sit still while the machine rotates around your head. There’s no discomfort, and the process takes less than a minute. Once complete, Dr. Colleran will review the images in detail to plan or adjust your treatment.

Benefits of CBCT may include:

• More accurate diagnoses and treatment plans
• Fewer surprises during procedures
• Improved communication and patient education
• Reduced need for exploratory surgery or guesswork
