摘要

牙种植体修复无牙患者的面部外观，改善咀嚼和说话能力。然而，实体种植体往往会造成应力屏蔽、种植体周围炎以及由于骨整合度低而导致骨整合不良，从而导致失败。为了解决这个问题，研究人员设计了三种多孔植入物——gyroroid、Schwarz Diamond （DI）和Schwarz primitive，并使用有限元分析（FEA）和计算流体动力学（CFD）对其进行了评估。FEA证实了机械稳定性，DI降低了骨应力，但增加了低密度骨的微运动。实验和计算结果表明，FEA对应力的预测略微过高，而CFD证实DI的渗透性与松质骨非常接近。

Biomechanical analysis of triply periodic minimal surfaces-based porous dental implants versus solid implants: impact of peri-implant bone density on micromotion.

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.
