More than solid – Roxolid®

Did you know?

Roxolid® is a metal alloy composed of ~ 15 % zirconium and ~ 85 % titanium. The combination of these two metals leads to a material with

higher tensile and fatigue strength than comparable Titanium implants1.

1. Roxolid® is stronger than Titanium Grade 4

Results

-0.60 mm(± 0.69 mm)

Titanium Roxolid®

The majority of implant sites showed crestal bone loss between 0 and 1.0 mm, or crestal bone gain.

3. Straumann® extends their Roxolid® implant guarantee

Roxolid® implants provide a clinically validated safe and reliable alter native to Titanium Grade 4 implants. The improved mechanical properties of Roxolid® extend the indications in implant therapy to more challenging clinical situations and allow promoting a minimal invasive treatment approach.

Fatigue strength is the long-term capability of the implant to withstand normal mastificatory forces

Straumann® has so much confidence in the quality and durability of every Roxolid® implant, that we offer

an industry-leading guarantee. The Roxolid® Lifetime Plus Guarantee not only covers the implant, but also

part of the treatment cost in case of an implant fracture.
