A modified polyetheretherketone (PEEK) framework material in combination with heat-polymerized denture base acrylic resin was used for the fabrication of an overlay prosthesis for a patient sensitive to base metals. High noble metal was used for the fabrication of the post/coping/ball attachment assemblies to promote retention and stability. These protruding attachments into the acrylic resin could result in stress concentration; therefore, a framework is often used to strengthen the prosthesis. PEEK frameworks could be a treatment alternative to high noble or Ti frameworks since they combine good mechanical properties with biocompatibility, reduced cost, and common laboratory procedures.
一种改良的聚醚醚酮(PEEK)框架材料与热聚合义齿基托树脂结合,用于为对贱金属敏感的患者制作覆盖义齿。高贵金属用于制作桩/牙合/球附着体组件,以提高固位力和稳定性。这些突出的附着体进入丙烯酸树脂可能会导致应力集中;因此,通常使用框架来增强义齿。PEEK 框架可以替代高贵金属或 Ti 框架,因为它们结合了良好的机械性能、生物相容性、降低成本和常见的实验室程序。
