All-on-X zirconia bridges are widely used for full-arch restorations due to their high strength and aesthetic performance. However, despite zirconia’s flexural strength often exceeding 900–1200 MPa, fractures still occur in clinical practice.
These failures are rarely caused by a single factor. Instead, they are typically the result of design, occlusion, fit, and long-term fatigue acting together.
