Abstract

Aim: This study aimed to investigate the biomechanical properties of 60 % carbon fiber-reinforced polyetheretherketone (Cfr-PEEK), which exhibits high mechanical strength and can address the limitations of titanium mini plates used in Le Fort I osteotomy.

Material and method: Models were created using the FEA method based on tomography images of adult individuals. A 5 mm maxillary advancement was applied to the models following Le Fort I osteotomy. Mini plates made of titanium and 60 % Cfr-PEEK were used. Support was provided by the nasomaxillary and zygomaticomaxillary buttresses to fix a total of four l-shaped mini plates. Oblique loads of 125 N, directed from palatal to buccal, and a total of 250 N compression loads were applied to the central fossa of the premolar and molar teeth in the maxillary model at a 30° angle relative to the long axis of the teeth. Displacement values at the osteotomy line, Von Mises stresses in the mini plate-screws, and principal stresses in the bone were compared.

Results: Examination of stress values in the fixation systems of the models revealed higher stress values in the Cfr-PEEK model compared to the titanium model. However, these stresses did not reach levels that would deform the Cfr-PEEK fixation systems. Stress and displacement values in the bone were lower in the Cfr-PEEK model compared to the titanium model.

Conclusion: According to the findings of our study, Cfr-PEEK represents a viable alternative to titanium for mini plate material in Le Fort I osteotomy, offering biomechanical advantages.

利用有限元分析评估钛和碳纤维增强聚醚醚酮迷你钢板在 Le Fort I 型推进截骨固定中的生物力学效应和稳定性。
目的:本研究旨在探讨60%碳纤维增强聚醚醚酮(Cfr-PEEK)的生物力学特性,该材料具有较高的机械强度,可解决勒堡I型截骨术中使用的钛迷你板的局限性:根据成人的断层扫描图像,使用有限元分析法创建模型。在 Le Fort I 型截骨术后,对模型进行 5 毫米的上颌骨前移。使用了由钛和 60% Cfr-PEEK 制成的迷你板。鼻颌托和颧颌托提供了支撑,共固定了四块 L 形迷你板。从腭侧到颊侧施加 125 牛顿的斜向载荷,并在上颌模型的前磨牙和磨牙中心窝施加总计 250 牛顿的压缩载荷,与牙齿长轴成 30° 角。比较了截骨线处的位移值、微型板状螺钉中的 Von Mises 应力和骨中的主应力:结果:对模型固定系统应力值的检查显示,Cfr-PEEK 模型的应力值高于钛模型。然而,这些应力并未达到导致 Cfr-PEEK 固定系统变形的水平。与钛模型相比,Cfr-PEEK 模型中骨骼的应力和位移值较低:根据我们的研究结果,在 Le Fort I 截骨术中,Cfr-PEEK 是钛迷你钢板材料的可行替代品,具有生物力学优势。
