摘要
背景:本研究旨在探讨基台材料、牙槽骨密度和咬合力对上颌前牙种植体周围应力分布的影响:进行了一项体外研究。在 D2 和 D3 骨中使用三维有限元模型对上颌前牙种植体进行建模,并使用三种不同的基台材料:钛、氧化锆和聚醚醚酮(PEEK)。在施加 100 N、175 N 和 250 N 的垂直和倾斜载荷后,对 Von Mises 应力进行了评估。统计分析采用 Friedman-Wilcoxon 符号秩检验、Mann-Whitney U 检验和 Kruskal-Wallis 检验。概率值 结果在所有基台材料中,D3 骨周围的应力分布均高于 D2 骨,斜向载荷的应力值大于垂直载荷的应力值,但差异不显著(P > 0.05)。PEEK材料的应力值高于钛或氧化锆基台,但差异不显著(P > 0.05)。在 100 N 和 175 N 负荷之间观察到有统计学意义的差异(P < 0.05):结论:PEEK、氧化锆和钛作为前牙基台材料显示出相似的特性。在垂直和倾斜载荷作用下,牙槽骨上的应力成比例增加,这表明骨嵴骨质流失受机械载荷的影响,而不是基台材料的类型。
A comparative finite element analysis of titanium, poly-ether-etherketone, and zirconia abutment on stress distribution around maxillary anterior implants.
Background: The aim of this study was to investigate the influence of abutment material, alveolar bone density, and occlusal forces on stress distribution around maxillary anterior implants.
Materials and methods: An in-vitro study was conducted. The maxillary anterior implant was modeled using a three-dimensional finite element model in D2 and D3 bones with three different abutment materials: titanium, zirconia, and poly-ether-ether ketone (PEEK). Von Mises stress was evaluated after the application of vertical and oblique loads of 100 N, 175 N, and 250 N. Statistical analysis was done by Friedman-Wilcoxon signed-rank test, Mann-Whitney U test, and Kruskal-Wallis test. The probability value <0.05 is considered a significant level.
Results: Stress distribution around D3 bone was higher than D2 bone in all the abutment materials with greater values seen in oblique load than vertical load with insignificant difference (P > 0.05). Statistically insignificant stress values were seen greater in PEEK than titanium or zirconia abutment (P > 0.05). A statistically significant difference was observed between 100 N and 175 N of load (P < 0.05).
Conclusion: PEEK, zirconia, and titanium as abutment material in the anterior region showed similar properties. The stress on the bone was proportionately increased during the vertical and oblique loads suggesting the influence of mechanical load in crestal bone loss rather than the type of abutment material.
