SURFACE TREATMENT

Surface Treatment

“Quality is never casual: It is always the result of intelligent effort”

The IML Research and Development team, in partnership with prestigious chemistry laboratories which specialise in implantology, has formulated the optimum surface treatment for their implants: the SL treatment.
The performance monitoring has been entrusted to the Polytechnic of Turin and to the University of Turin, which also periodically check production lots.
IML SL treatment is technically comparable to the best SLA® treatments, the most documented in the literature, and it is carried out using a sand-blasting technique, with
different grain sizes, followed by etching of the surface using acid solutions.
The resulting surface has an appropriate structure for anchoring osteoblasts and promotes good integration of the implant with the bone tissue. In fact, this type of treatment suits any type of bone thanks to its ability to increase primary stability even in the presence of atrophic sites or compromised biological tissue.
Cell adhesion and roughness: laboratory analysis on IML SL treated implants
Aware of the key role played by the surface treatment in determining the speed and quality of osseointegration of a dental implant, IML has always invested considerable resources in designing surfaces that facilitate the cell adhesion.
The tests carried out by the University of Turin on implants with IML SL treatment confirm the effectiveness of the topography and of the surface chemistry developed by the IML Research and Development team.
According to reports of the University of Turin and in accordance with protocols of the international literature, 24 hours after cell seeding on Starfly, Universe and Power SL treated implants, it is possible to appreciate the uniformity of the growth and of the cell adhesion over the entire implant surface.
Furthermore, observing by microscope the nuclei (marked in blue) and the cytoskeleton (marked in red), it is evident that after 24 hours the cells not only have a very branched growth, with long filopodia and a complex morphology, but they are also multiplying in number. These are all indicators of the cellular behaviour on the IML SL treated surface.
Another fundamental factor, determined by the surface treatment and constantly monitored by laboratory analysis, is the roughness, that is the result of the unevenness on the surface.
During the surface analysis on Starfly, Universe and Power implants, the CNR (National Research Council) of Turin examines the average roughness (Ra/Sa), the Skewness parameter (Rsk/Ssk), representing the prevalent symmetry, and the Kurtosis parameter (Rku/ Sku), representing the indentation density.
The resulting values, in relation to the international literature, confirm that the IML SL treated surfaces have an optimal roughness, homogeneously distributed.
