ADS® surface treatment
To promote the adhesion and growth of bone cells, the outer surface of the implant has been treated with the exclusive ADS® treatment (Advanced Double-Grip Surface) which combines a white corundum micro-bubble treatment and acid etching, for a non-smooth roughness that maximizes the contact surface between implant and bone and therefore improves stability and adhesion between them.
The ADS® treatment is the result of a series of collaborations with institutes and universities, as well as our own research and tests, that allow us to monitor and validate the optimal biological response to the implant surface: chemical (X-ray scattering studies to find out the composition of the implant and its surface) and topography studies (roughness studies) have been carried out, as well as biological (in vivo response studies in animals) and clinical studies.
Composition studies
X-ray scattering studies show that the surface of the implants is only made up of titanium and oxygen, which are the basic components of the oxide layer that forms in the implant passivation process and that gives it its excellent corrosion resistance.
Surface topography studies
In order to control and identify the topography of the implant surface, roughness studies were performed with profilometer, as well as with techniques such as SEM (Scanning Electron Microscope) and CLSM (Confocal Laser Scanning Microscope), allowing to obtain and control the mean roughness (Ra) values within the parameters recommended in international publications.

Osseointegration studies
To determine the biological response of GMI implants, in vivo studies were conducted by inserting the implants on animals, leaving them without load during the healing process and performing a histological study to prove the excellent response of the bone cells and the complete osseointegration of the implant.
