Leader Italia Tixos Line Dental Implant System

Tixos Implant by Leader Italia, is the result of 4 years research on new technology applied to Titanium. The structure and morphology of the implant surface are designed by a computer that, with a focused laser beam, produces the desired model by sintering the titanium powder layer after layer. This technology, also known as Laser Microfused Titanium Powder, allows the production of a porous surface characterized by open intercommunicating cavities that widen to an established depth.

Geometry of Implants Surfaces

Recent studies showed the importance of surface geometry in promoting bone formation also in extraskeletal sites. The implant topographic surface modification may optimize the interactions with host tissue during healing phase, in order to obtain the best tissue response in a shorter time.

The surface geometry constituted by a sequence of concavities that go continuing in an underlying porous network seems to be able to directly stimulate the cells to give complete expression of the osteogenic phenotype.

The osteoblasts together with growth factors and specific cytokines, that is, molecular signals that govern cellular activity, tend to preferentially concentrate into concavities.

This is the natural process taking place during the bone remodelling phase, a genetically regulated and coded phenomenon, which has been characterizing the life of all organisms with skeleton for millions of years. During bone remodelling, osteoclasts resorb bone, thus creating cavities that are immediately populated by vessels and osteoblasts able to form new bone. Cavities represent indeed a real “universal motive” of bone tissuE.”

The DLMF (Direct Laser Metal Forming) technique, a new Rapid Prototyping (RP) application, allows the manufacture of implants with controlled porosity, pore size, shape and interconnections.Using DLMF, it is now possible to fabricate dental implants with different shape and texture, by the laser fusion of titanium microparticles.

As proved by Anoticel Susej Method, DLMF allows the manufacturing of implants with graded isoelasticity values, which are similar to those of the surrounding bone, from the inner core to the outer surface. This new functionally graded material has the potential to transfer the loading stress more naturally.

    I’m afraid the surface will accumulate calculus. It will be too hard to clean because of roughness of its surface. Is this the actual implant body?
