Due to the rapid rate of post-extraction ridge resorption, low-density trabecular bone patterns (Type III and IV bone), and intimate proximity to critical landmarks—such as the incisive canal, the nasal floor, and the pneumatized maxillary sinus—relying on traditional two-dimensional radiography is no longer sufficient.
Achieving long-term osseointegration and predictable prosthetic outcomes demands a thorough, three-dimensional diagnostic evaluation prior to surgical intervention.
Published in Diagnostics (MDPI), this clinical update critically examines the role of Cone Beam Computed Tomography (CBCT) as the definitive imaging standard for maxillary implant surgery.
The review highlights CBCT's capability to deliver high-resolution volumetric imaging with optimized radiation doses, allowing clinicians to precisely evaluate alveolar bone dimensions, map out subclinical cortical defects, and assess bone quality using Hounsfield-equivalent density metrics and the Lekholm & Zarb classification.
Beyond structural bone mapping, the paper provides an updated synthesis on utilizing CBCT data to determine the necessity, timing, and design of hard-tissue grafting—ranging from horizontal ridge augmentation to transcrestal and lateral window sinus elevations.
Furthermore, the authors underscore how 3D radiographic assessment integrates into digital guided surgery workflows, mitigating surgical complications and ensuring prosthetically driven fixture placement.
For implantologists, periodontists, and oral maxillofacial surgeons, this update delivers an essential, evidence-based diagnostic framework to navigate maxillary anatomical challenges with maximum surgical safety and precision.
