摘要

背景和目的:本研究使用有限元分析评估基台角度、类型和框架材料对种植牙系统应力分布和疲劳性能的影响。材料与方法:对上颌三单元固定种植体支持修复体的三维模型进行分析。使用了不同角度和类型的基台。使用了两种不同的框架材料。在种植体上斜向施加 150 牛顿的力,从腭侧到颊侧,特定角度为 30 度。然后,考虑到所使用的修复框架类型和基台在三个不同位置的角度,对应力分布和疲劳性能进行了评估。研究的模拟方面采用了 Abaqus 软件(ABAQUS 2020,达索系统仿真公司,美国 RT 州约翰斯顿市)。研究结果在所有模型中,前磨牙区域的疲劳强度均高于磨牙区域。最大应力水平出现在带角度种植体的模型中。在几乎所有使用氧化锆框架的模型中,疲劳强度都略低。结论:根据这项研究的结果,可以得出结论:使用最小角度的金属框架多单位修复体对生物力学和种植治疗的长期成功有显著的积极影响。

Influence of Framework Material and Abutment Configuration on Fatigue Performance in Dental Implant Systems: A Finite Element Analysis
Background and Objectives: This study uses finite element analysis to evaluate the impact of abutment angulation, types, and framework materials on the stress distribution and fatigue performance of dental implant systems. Materials and Methods: Three-dimensional models of maxillary three-unit fixed implant-supported prostheses were analyzed. Abutments with different angles and types were used. Two different framework materials were used. Conducted on implants, a force of 150 N was applied obliquely, directed from the palatal to the buccal aspect, at a specific angle of 30 degrees. The distribution of stress and fatigue performance were then assessed, considering the types of restoration frameworks used and the angles of the abutments in three distinct locations. The simulation aspect of the research was carried out utilizing Abaqus Software (ABAQUS 2020, Dassault Systems Simulation Corp., Johnston, RT, USA). Results: In all models, fatigue strengths in the premolar region were higher than in the molar region. Maximum stress levels were seen in models with angled implants. In almost all models with the zirconia framework, fatigue performance was slightly lower. Conclusions: According to the findings of this study, it was concluded that the use of metal-framework multi-unit restorations with minimum angulation has significant positive effects on the biomechanics and long-term success of implant treatments.
