Abstract

Objectives: 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.

Materials and methods: 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.

Results: All three implant assemblies, i.e., GFR-PEEK, zirconia, and titanium, demonstrated similar stresses and deformation in bone without significant difference.

Conclusion: It was concluded that GFR-PEEK and zirconia implants can be used as a substitute to titanium implants.

用有限元分析评估玻璃纤维增强聚醚醚酮、氧化锆和钛植入物在骨中的应力和变形。

目的:近年来，氧化锆陶瓷和玻璃或碳纤维增强聚醚醚酮(PEEK)复合材料作为较新的植入生物材料被引入。本研究评估了玻璃纤维增强(GFR)-PEEK、氧化锆和钛植入物对骨的应力和变形。材料与方法:制作种植冠代替下颌磨牙的几何模型。种植体长度为12mm，直径为4.5 mm。建立了GFR-PEEK、锆、钛三种材料种植体组件的有限元分析模型。沿种植体长轴斜向和垂直方向施加150 N载荷。利用ANSYS Workbench 17.0和有限元软件对产生的Von Mises应力和变形进行比较。结果:GFR-PEEK、氧化锆和钛三种种植体组件在骨内的应力和变形相似，无显著差异。结论:GFR-PEEK和氧化锆种植体可作为钛种植体的替代材料。
