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.
