Recently, zirconia ceramic and glass or carbon fiber-reinforced poly-ether-ether-ketone (PEEK) composites have been introduced as newer implant biomaterials. This study was done to evaluate stress and deformation in bone with glass fiber-reinforced (GFR)-PEEK, zirconia, and titanium implants.
A geometric model of mandibular molar replaced with implant-supported crown was generated. Implant of 12 mm length and 4.5 mm diameter was used in study. Finite element analysis models of implant assemblies of three materials GFR-PEEK, zirconium, and titanium were generated. 150 N loads were applied obliquely and vertically along the long axis of implant. Von Mises stresses and deformation generated were compared using ANSYS Workbench 17.0 and finite element software.
All three implant assemblies, i.e., GFR-PEEK, zirconia, and titanium, demonstrated similar stresses and deformation in bone without significant difference.
It was concluded that GFR-PEEK and zirconia implants can be used as a substitute to titanium implants.
最近，氧化锆陶瓷以及玻璃或碳纤维增强聚醚醚酮（PEEK）复合材料作为新型植入生物材料被引入。本研究旨在评估玻璃纤维增强（GFR）-PEEK、氧化锆和钛植入物在骨中的应力和变形情况。
建立了用种植体支持冠修复下颌磨牙的几何模型。研究中使用长度为12mm、直径为4.5mm的种植体。生成了三种材料（GFR-PEEK、锆和钛）的种植体组件的有限元分析模型。沿种植体长轴倾斜和垂直施加150N的载荷。使用ANSYS Workbench 17.0和有限元软件比较产生的冯·米塞斯应力和变形。
所有三种种植体组件，即GFR-PEEK、氧化锆和钛，在骨中表现出相似的应力和变形，无显著差异。
得出的结论是，GFR-PEEK和氧化锆植入物可作为钛植入物的替代品。
