Full-arch implant cases can be highly rewarding, but small errors at any stage can lead to complications, misfit, and long-term failure. In this session, Kevin Armstrong will break down the most common reasons full-arch cases fail, from planning and component selection through to workflow and communication between clinic and lab. He will share practical insights on how to improve accuracy, achieve passive fit, and create predictable outcomes using modern digital and analogue techniques. Attendees will leave with clear, actionable steps to reduce complications and deliver more reliable full-arch restorations.
