Description
Dijana Popovic Grubac and seven co-authors stress-test the metal and ceramic frames behind full-arch implant teeth, in a 2026 computer study. The all-on-four method anchors a full upper set of teeth on just four implants, a lifeline for people who have lost all upper teeth. The frame material tying the implants together decides how chewing forces spread.
Six virtual models of a shrunken upper jaw were built with three frame materials: cobalt-chromium alloy, zirconia, and a high-grade plastic. Static loads up to 200 newtons and chewing-like dynamic loads were applied. Stress maps, fatigue estimates, and frame movement were compared. The results help dentists pick a frame that balances strength, weight, and cost for each patient’s bite.
