Comparison

Straumann vs Osstem: what really differs?

Straumann and Osstem are often offered side by side at very different prices. Here is what differs in design and public record, and what doesn't follow from that.

What actually differs
  • Different materials (Ti-Zr vs CP titanium) and connections.12
  • Straumann has a longer FDA history.
  • A lower price does not by itself mean a worse outcome, and a higher price doesn't guarantee a better one.
