Abstract

Purpose: The microstructural characteristics of trabecular bone were identified using micro-computed tomography (micro-CT), in order to develop a potential strategy for implant surface improvement to facilitate osseointegration. Methods: Alveolar bone specimens from the cadavers of 30 humans were scanned by high-resolution micro-CT and reconstructed. Volumes of interest chosen within the jaw were classified according to Hounsfield units into 4 bone quality categories. Several structural parameters were measured and statistically analyzed. Results: Alveolar bone specimens with D1 bone quality had significantly higher values for all structural parameters than the other bone quality categories, except for trabecular thickness (Tb. Th). The percentage of bone volume, trabecular separation (Tb. Sp), and trabecular number (Tb. N) varied significantly among bone quality categories. Tb. Sp varied markedly across the bone quality categories (D1: 0.59±0.22 mm, D4: 1.20±0.48 mm), whereas Tb. Th had similar values (D1: 0.30±0.08 mm, D4: 0.22±0.05 mm). Conclusions: Bone quality depended on Tb. Sp and number-that is, endosteal space architecture-rather than bone surface and Tb. Th. Regardless of bone quality, Tb. Th showed little variation. These factors should be taken into account when developing individualized implant surface topographies.
