Abstract

This study investigates the impact of tightening torque (preload) and the friction coefficient on stress generation and fatigue resistance of a Ti-6Al-4V abutment screw with an internal hexagonal connection under dynamic multi-axial masticatory loads in high-cycle fatigue (HCF) conditions. A three-dimensional model of the implant-abutment assembly was simulated using ANSYS Workbench 16.2 computer aided engineering software with chewing forces ranging from 300 N to 1000 N, evaluated over 1.35 × 10 cycles, simulating 15 years of service. Results indicate that the healthy range of normal to maximal mastication forces (300-550 N) preserved the screw's structural integrity, while higher loads (≥800 N) exceeded the Ti-6Al-4V alloy's yield strength, indicating a risk of plastic deformation under extreme conditions. Stress peaked near the end of the occluding phase (206.5 ms), marking a critical temporal point for fatigue accumulation. Optimizing the friction coefficient (0.5 µ) and preload management improved stress distribution, minimized fatigue damage, and ensured joint stability. Masticatory forces up to 550 N were well within the abutment screw's capacity to sustain extended service life and maintain its elastic behavior.

摘要

本研究调查了在高周疲劳（HCF）条件下，动态多轴咀嚼载荷作用下，拧紧扭矩（预紧力）和摩擦系数对具有内六角连接的Ti-6Al-4V基台螺钉应力产生和抗疲劳性能的影响。使用ANSYS Workbench 16.2计算机辅助工程软件对种植体-基台组件的三维模型进行了模拟，咀嚼力范围为300 N至1000 N，评估了1.35×10次循环，模拟15年的使用期限。结果表明，正常至最大咀嚼力的健康范围（300-550 N）保持了螺钉的结构完整性，而更高的载荷（≥800 N）超过了Ti-6Al-4V合金的屈服强度，表明在极端条件下存在塑性变形的风险。应力在咬合阶段结束时（206.5毫秒）达到峰值，这是疲劳积累的关键时间点。优化摩擦系数（0.5 µ）和预紧力管理可改善应力分布，将疲劳损伤降至最低，并确保关节稳定性。高达550 N的咀嚼力完全在基台螺钉维持延长使用寿命和保持其弹性行为的能力范围内。
