| Cone Beam CT Scan Basalt CO Cone Beam CT Scan provided by Dr. Marcus Blue in Basalt, CO at Blue Periodontics  When periodontal disease has damaged the bone supporting a tooth, saving that tooth often depends on more than removing infection. It depends on rebuilding what has been lost. At Blue Periodontics, we use cone beam CT (CBCT) imaging to evaluate bone defects in detail before recommending regenerative surgery, allowing our team to plan a procedure suited to the exact shape and severity of the defect rather than relying on assumptions made during a visual exam alone.Why Defect Shape MattersNot all bone loss from periodontal disease looks the same, even when the pocket depths measured during an exam appear similar from one tooth to the next. Bone can be lost in a shallow, wide pattern, or it can create a deep, narrow defect confined to one or two surfaces of the root. These different shapes respond very differently to treatment. A defect with several remaining bone walls tends to regenerate well with grafting material and a barrier membrane, while a shallow, wide defect with little surrounding bone structure may have a much more limited capacity to regenerate, regardless of the materials used. Traditional periodontal probing and two-dimensional X-rays give us a general sense of bone loss, but they cannot reliably show how many walls of bone remain around a defect or how the defect is shaped in three dimensions. A flat X-ray shows a shadow that suggests bone loss is present, but it cannot show whether that loss follows the front and back surfaces of the tooth, wraps around toward the tongue or cheek side, or forms a narrow, isolated pocket adjacent to the root. What a CBCT Scan Reveals Before SurgeryA cone beam scan allows our team to view a periodontal defect from any angle and slice through the bone at the precise location of concern. This makes it possible to identify how many bony walls surround the defect, measure its depth and width with accuracy, and see its relationship to the roots of adjacent teeth before a flap is ever raised. In cases involving multi-rooted molars, the scan also clarifies whether bone loss has progressed into the furcation, the area where the roots divide, which significantly changes the surgical approach and the likelihood of a successful outcome. This information shapes several key decisions before surgery begins. It helps determine whether a defect is a good candidate for regeneration at all, since some patterns of bone loss are simply not conducive to rebuilding regardless of technique. It also helps our team select the most appropriate combination of bone grafting material and barrier membrane for the defect's specific architecture, and it allows for a more accurate discussion with the patient about what outcome can realistically be expected. Reducing Surprises in the Surgical ChairOne of the most valuable aspects of three-dimensional imaging is what it removes from the surgical appointment: uncertainty. When a periodontal surgeon walks into a procedure already knowing the number of bone walls present, the defect's exact dimensions, and its proximity to adjacent roots or anatomical structures, the surgery itself becomes more efficient and more predictable. Decisions that might otherwise need to be made in real time, based on what is discovered once the tissue is reflected, can instead be planned in advance. This is particularly important when regenerative material and membrane selection need to be prepared before the appointment. Knowing the defect's dimensions ahead of time allows our team to have the appropriate materials on hand rather than adjusting the plan mid-procedure, which supports both surgical efficiency and a more comfortable experience for the patient. Coordinating With Restorative TreatmentRegenerative periodontal surgery rarely happens in isolation from the rest of a patient's dental care. A tooth being considered for regeneration may also need a crown replacement or may be under evaluation as a candidate for an implant if regeneration is not expected to succeed. Detailed three-dimensional imaging allows our team to coordinate more effectively with a patient's general dentist or prosthodontist, since everyone involved can review the same bone architecture and agree on a treatment sequence. This is particularly relevant when a tooth is borderline between saving through regeneration and planning for extraction and implant replacement. A favorable defect pattern supports a confident recommendation to proceed with regeneration, while a wide, shallow defect with minimal remaining bone support may instead point the conversation toward extraction and future implant planning, sparing the patient a procedure with a low likelihood of success. Evaluating Outcomes Over TimeCBCT imaging is also useful after regenerative treatment has been completed. Because the scan can be repeated and compared to the original pre-surgical images, our team can assess how much new bone has formed at the treated site and confirm that healing is progressing as expected. This is a level of objective, three-dimensional follow-up that pocket depth measurements and two-dimensional X-rays cannot fully replicate, and it allows us to identify early if a site is not responding as anticipated and adjust the maintenance plan accordingly. Setting Realistic ExpectationsRegenerative periodontal surgery can produce meaningful, lasting improvement, but outcomes depend heavily on the underlying anatomy of the defect being treated. Part of our responsibility as periodontal specialists is to set expectations that are grounded in an accurate understanding of what a given defect can realistically achieve, rather than a general promise of bone regrowth. Three-dimensional imaging gives us the diagnostic foundation to have that conversation honestly, before any decision about surgery has been made. This approach also helps patients understand why two teeth with seemingly similar symptoms may receive very different treatment recommendations. The difference often comes down to defect architecture that is only visible through three-dimensional imaging, and being able to show a patient their own scan helps make that distinction clear. A Foundation for Better Surgical Decisions
At Blue Periodontics, cone beam CT imaging has become a standard part of how we plan regenerative periodontal procedures. It allows our team to approach each case with a complete picture of the bone defect involved, select the treatment approach best suited to that specific anatomy, and set expectations that reflect what the tooth and surrounding bone can realistically support. If you have been told that a tooth may benefit from regenerative periodontal surgery, or if you would like to better understand what your own imaging shows, our dental team is happy to walk you through the findings and the reasoning behind our treatment recommendations.
