科学领域:

  • 牙科植入物学 牙科植入物学
  • 生物材料科学 生物材料科学
  • 数字牙科数字牙科

背景情况:

  • 精确合适的磨砂假肢对于长期的牙植入成功至关重要.
  • 了解植入物间距离对假肢适配的影响对于数字工作流程至关重要.

研究的目的:

  • 评估不同的植入间距离如何影响磨-结构的真实性和适合性.
  • 为了比较扫描电子显微镜 (SEM) 和数字放射学用于不合适的评估.

主要方法:

  • 用 7,14 和 21 毫米的植入物间距离对类型体模型进行口腔内扫描.
  • 造的多单元结构的制造和SEM/数字放射分析.
  • 在植入物接口上进行三维 (3D) 的真实性评估和不合适分析.

主要成果:

  • 在不同植入物间距离之间没有观察到3D真实性或不合适的显著差异.
  • 在SEM和数字放射学不适合测量之间发现了强烈的相关性 (皮尔森r = 0.819,p = 0.045).
  • 所有造结构都表现出很好的适应植入物支柱.

结论:

  • 植入物间的距离不会显著影响磨砂植入物支持的修复的真实性或合适性.
  • 数字放射学是一种可靠和有效的方法,用于评估植入物假体的不适合性.
  • 这项研究验证了植入牙科中数字工作流程的精度.
