Passive Fit for Implant‑Supported Titanium Frameworks

Passive fit is a core requirement for SLM‑printed titanium implant frameworks. A misfitting prosthesis will generate extra stress, trigger bone resorption and even loosen implants. The tolerance target should stay below 20 microns. Technicians need to ensure abutments are fully tightened on implant analogs before scanning and printing. Never mix components from different implant systems, as platform shapes and anti‑rotation structures vary greatly. Double‑checking connections effectively avoids costly clinical failures.
