An anatomical study of the alveolar process in the human maxilla and its relation to the maxillary sinus using μ‐CT: to facilitate successful dental implants

Dental implants are a beneficial solution to restore a healthy and aesthetic smile for edentulous patients; however, implant placement in the posterior maxilla remains problematic due to morphological characteristics that can hinder proper osseointegration. Knowledge of height and width of the alveolar margin, thickness of cortical bone and location of the maxillary sinus remain preoperative concerns. Current imaging modalities do not allow accurate visualization of these bucco‐lingual dimensions. Micro‐CT is a recent development in imaging technology that enables fine details to be defined. This study will determine the accuracy of using μ‐CT for determining important measurements within posterior, edentulous maxillae. 16 cadaveric, edentulous, hemi‐maxillae were dissected and μ‐CT images taken at a slice thickness of 154 μm. Dimensions of alveolar bone height, width, and proximity to the sinus were measured in molar and premolar areas, using 3D visualization and modeling software (Amira). These measurements were then compared to standard calliper measurements. Results are currently pending but this study will verify the accuracy of using μ‐CT for morphological characterization of edentulous maxillae.
