Abstract
Polymethyl methacrylate (PMMA), widely used in prosthodontics, often fails under heavy masticatory forces due to low impact strength and fatigue resistance. Cobalt-chromium metal frameworks offer a durable alternative, particularly in complex cases. This case series highlights three examples: a patient with repeated PMMA denture fractures resolved with a cobalt-chromium design, a tongue-tie patient with opposing natural teeth stabilized by a metal framework, and an OSMF patient with limited oral access successfully rehabilitated using a metal-based denture. While metal frameworks may have aesthetic and weight limitations, their advantages in fracture resistance, longevity, and functionality make them invaluable for challenging clinical scenarios.
