Bone integration
Based on the success of Straumann's TPS surface, the ITI and
Straumann developed an improved surface called SLA
(sand-blasted, large grit, acid-etched). Both the TPS and SLA*
surface consist chemically of titanium oxide. However, the SLA*
surface does not have the semi porous structure of the TPS
surface and is not a coating but rather a surface treatment.
The SLA* surface is produced by a coarse sand-blasting process,
which leads to macro roughness on the titanium, and outstanding
bone fixation is achieved as a result. This process is followed
by etching in acid, which produces micropits that can be seen on
SEM images, which promote cell activity on the surface.
The new SLA* surface treatment leads to more intensive
bone-implant contact, confirmed by high release moments, which
allow earlier functional loading. In healthy patients with good
bone quality and quantity, this clinically tested surface
provides the possibility of placing the abutment and prosthesis
after only 6 weeks after the implant surgery.

Material titanium, grade 4
All ITI implants consist of commercially pure titanium (grade
4-ISO 5832/II).Titanium is biocompatible, i.e. this material is
integrated by the tissues of the body without complications, and
no allergic immune reactions have been identified. In air, water
and any electrolytes, an oxide forms on the surface of titanium,
which is one of the most resistant substances in the mineral
world. It protects the metal against chemical attack even in
aggressive body fluids. The bone grows into the rough surface of
the implant and thus sticks to the titanium.
This fixation provides the best possible conditions for the
function of a dental implant, as all of the forces that arise
are transmitted to the surrounding bone. The increased strength
of the ITI implants is achieved by cold distortion and heat
treatment. |
