Periodontal and implant CBCT applications — the use of three-dimensional bone assessment for implant site evaluation, bone grafting planning, periodontal defect characterization, and sinus augmentation planning — represent the commercially highest-value CBCT application category in dentistry, with the CBCT Dental Market reflecting implant dentistry as the strongest CBCT adoption driver.

Pre-implant CBCT assessment provides bone height, width, density, and proximity to vital structures (inferior alveolar nerve, sinus floor, adjacent roots) that cannot be reliably measured on panoramic radiography. The clinical consequence of placing implants without adequate 3D assessment — nerve damage, sinus perforation, adjacent root injury — creates the liability-driven clinical rationale that has made pre-implant CBCT standard of care at most implant-focused dental practices.

Sinus lift planning — the maxillary sinus augmentation procedure required when insufficient bone exists for posterior maxillary implants — requires precise measurement of sinus floor topography, membrane thickness, presence of septa, and available bone height only reliably obtained from CBCT. The complexity of sinus anatomy visible only in three dimensions creating the mandatory CBCT planning indication for this high-risk procedure.

Periodontal defect characterization — the three-dimensional assessment of infrabony defects, furcation involvement, and bone morphology critical for regenerative periodontal surgery planning — represents the periodontal specialty CBCT indication. Identifying three-wall intrabony defects (most favorable for regenerative treatment) requiring 3D assessment that two-dimensional periapical radiography cannot provide.

Do you think CBCT should be considered mandatory standard of care before any dental implant placement, or is clinical examination plus panoramic radiography sufficient for straightforward anterior implant cases?

FAQ

What implant-related assessments require CBCT? Bone height and width measurement, bone density assessment, inferior alveolar nerve localization, sinus floor position and anatomy, adjacent root proximity, fenestration/dehiscence risk assessment — all critical implant parameters measurable accurately only with CBCT 3D imaging.

What is the clinical standard for CBCT before sinus lift procedures? CBCT considered standard of care before sinus augmentation; provides: residual bone height measurement, sinus membrane thickness, septal anatomy, presence of pathology, sinus dimensions — all critical for surgical planning and risk assessment; panoramic radiography considered insufficient for complex sinus cases.
