When is Passivity Plus™ the right choice, and when isn't it?

Passivity Plus™ is designed to compensate for minor misfits in full-arch implant restorations, not to correct major errors. Understanding when to use it, when to avoid it, and how it affects verification workflows is essential for predictable outcomes.

As the inventor states: "We can fix for sure normal errors, not crazy errors."

When to Use vs. When to Avoid

Use Passivity Plus™ When... Do NOT Use Passivity Plus™ When...
Fabricating new full-arch prostheses on multi-unit abutments Scan quality is poor (shadows, artifacts, overlapping scan bodies, data gaps)
Minor passive fit discrepancies are anticipated Prosthesis fit is grossly off (excessive rocking or wobbling)
Replacing existing prostheses with minor fit issues Model accuracy is significantly compromised
Cases use titanium bar substructures Major impression errors are present
Upgrading from conventional Ti-base systems Gross implant position discrepancies exist
Switching from direct-to-MUA Errors fall outside the minor range ("crazy errors")

Does It Eliminate the Need for Verification Jigs?

In many cases, yes. Passivity Plus™ compensates for the minor misfits that would otherwise require verification and correction, reducing the need for jigs in straightforward cases.

However, it is not a substitute for correcting major impression or model errors. Verification jigs remain valuable when:

  • Implant positions need to be confirmed in complex cases
  • Scan quality is questionable
  • There is reason to suspect the misfit may exceed the minor adjustment range

The Bottom Line

Passivity Plus™ handles the routine, inevitable discrepancies that accumulate from digital and analog workflows. It does not replace fundamental clinical judgment or the need for accurate records when the case demands them.
