Abstract
The long-term success of implant-supported overdentures depends significantly on the mechanical durability of the attachment system and the compatibility of the denture base materials. Stud attachments like Locator, Ball, and ERA are commonly used, each interacting differently with acrylic resins and high-performance polymers.
Objective: This in vitro study aimed to evaluate and compare the fatigue resistance of various stud attachments—Locator, Ball, and ERA—when combined with different denture base materials: heat-cured polymethyl methacrylate (PMMA), injection-molded PMMA, and polyetheretherketone (PEEK).
