Research methodology
Source priority
| Tier | Sources | Used for |
|---|---|---|
| 1 | Regulatory: FDA 510(k), recall database, AccessGUDID, EUDAMED | Regulatory status, device descriptions, labelled indications |
| 2 | Systematic reviews, consensus reports, guidelines | Clinical conclusions |
| 3 | Primary clinical studies | Specific outcomes, with limitations stated |
| 4 | Official Straumann documentation | Product specifications; labelled as manufacturer information |
| 5 | Secondary professional sources | Background only; never sole support |
Claim register
Important clinical statements are stored in a claim register with their sources, evidence level, whether they are manufacturer claims, and a verification date. Pages cannot be published if a referenced claim has no source.
Conflicts between sources
We show both. Example: Straumann describes Roxolid® as 85% titanium / 15% zirconium, while its FDA filings describe a Ti-13Zr alloy. Both are shown with their sources.
