奈米多孔性牙科植體之應力分析
Stress Analysis on Dental Implant with Novel Nanoporous Surface Functionalization
並列摘要
The objective of this study was to investigate the stress distributions of a surface-treated dental implant and bone tissue under physiological loading. For ensuring success of dental implant treatment, one must examine the magnitude and location of the maximum stresses. Stress analysis models were constructed from computer tomography data. Although several studies have investigated finite element models of dental implants, none have used an implant model with a nano-porous layer in a biomimetic geometrical mandible model. The novel implant surface used in this study, comprised of a micro-level porous containing a nano-level porous structure, was complex and it was difficult to present due to the limitation of computer efficiency. However, this complex geometry was simplified using a film, to further investigate stresses resulting from 0 nm, 50 nm, 500 nm, 5 μm, and 50 μm surface treatment thicknesses. Results indicated that the stresses transferred more uniformly in implants with nano-porous surface treatments, and that the stresses decreased with increasing layer thickness
