and acid etching
on titanium

The combined-action process that reduces the risk of contamination and improves the osseointegration capability of objects.

The production cycles for the combined sandblasting and double acid etching process involve:

  • 01.

    Initial phase with pretreatment, washing and rinsing the implants received, to ensure they are all thoroughly clean, eliminating or minimising the presence of oils and grease coming from external mechanical processes.

  • 02.

    After the initial wash, sandblasting with aluminium oxide is carried out on the implants. The sandblasted part is then washed, which is followed by chemical pickling treatment and acid etching.

  • 03.

    Next step is the neutralisation process, washing and rinsing with water to eliminate chemical residue left behind by the pickling and etching process.

  • 04.

    After washing, the implants are dried and decontaminated with a plasma treatment.

    Treatment carried out in compliance with standard 13485:2016 and the new MDR 745/2017

Benefits of sandblasting
and acid etching

  • 01.

    Simultaneous, homogeneous treatment on material (sandblasting+double acid etching)

  • 02.

    Reduction in risk of surfaces being contaminated with extraneous microparticles

  • 03.

    Excellent osteointegration capability

Process of sandblasting and acid etching

The technique of sandblasting and double acid etching on titanium involves creating macro roughness followed by etching with acid, which puts micro roughness over the prior macro roughness.

This treatment is of considerable use and importance in the dental sector.

Since 1996, Alticolor has been the trusted point of reference for companies in need of treatments on titanium components.

Alticolor treatments undergo rigorous control procedures
resulting in certification to guarantee the quality
of the process management.
