Why Passive Fit Matters in Full-Arch Restorations
Passive fit is not a marketing term — it is the mechanical condition that protects the implant interface over the years the restoration must perform.
A full-arch restoration is only as reliable as the fit between its framework and the implants that support it. When a framework seats without inducing stress on the implant interface, it is said to have passive fit — and it is the mechanical condition that protects implant longevity.
At ALL-ON-X ARTIFEX, every full-arch framework is designed and manufactured digitally and inspected against the digital model before delivery. Marginal fit and the interarch relationship are checked at quality control — the stage where our standards are measured, not estimated.
Passive fit is not achieved by luck or by hand-fitting at the chair. It is designed in — through virtual treatment planning, CAD design, and CAM manufacturing that hold tolerance consistently across cases. That consistency is what makes outcomes predictable.
