Anodizing Type II (DOTIZE®)
Technology
The DOTIZE® anodizing process replaces the thin natural oxide film present at the implant surface by a thick oxide layer. Micropores and cracks in the base material are reduced by the anodization. The DOTIZE® procedure conforms to the standard AMS 2488 (Aerospace Material Specification).

Range of Application
- Traumatological implants (bone screws, bone nails etc), which should be removed after a defined time and therefore should not be integrated into bone tissue
Advantages of the Procedure
- Easier removal of the implants after fracture healing
- Higher pre-loading of threaded connections is possible
- Increased resistance to wear compared with untreated titanium alloys
- Increase of up to 15 % in the fatigue strength compared with untreated base material
- No significant changes in implant dimensions
Properties
- Color: dark gray to anthracite
- Coating thickness: 1–2 µm
- Roughness Rz: ≤ 3 µm
- Adhesion strength: ≥ 22 MPa
- Hardness: Increase of ~25 %
- Hardened titanium surface
- Good biocompatibility
- Reduction in the risk of cold welding between titanium implants
