Abstract
Dental implants restore facial appearance and improve chewing and speaking abilities in edentulous patients. However, solid implants often cause stress shielding, peri-implantitis, and poor bone integration due to low osteointegration, leading to failure. To address this, three porous implants-Gyroid, Schwarz Diamond (DI), and Schwarz Primitive-were designed and evaluated using Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD). FEA confirmed mechanical stability, with DI reducing bone stress but increasing micromotion in lower-density bone. Experimental and computational testing showed FEA slightly overpredicted stress, while CFD confirmed DI's permeability closely matches cancellous bone.
期刊介绍：
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
