Direct Laser Metal Forming technique
The new laser technologies allow the fabrication of models with defined form and structure determined on the basis of virtual 3D models. These technologies today can be used to create different materials, among which also titanium and its alloys.
After years of researches in cooperation with several international Universities and Research Centers, LEADER ITALIA has developed and patented a new revolutionary surface, thanks to this new production process applied to Titanium.
The new technology DLMF (Direct Laser Metal Forming), presents several advantages and opens up a new future in implantology, allowing the manufacturing of implants with predetermined shapes, proportions, surface morphology and structural features, as previously computer designed in 3D.
Once the model has been projected, a computer-guided laser beam provides for the microfusion of the titanium powder by layers, as to obtain the desired implant.

The new LEADING surface
The surface resulting by this innovative production process is characterized by intercommunicating cavities that replicates the bone structure, structure that is impossible to obtain through the traditional treating surface processes.
The cavities geometry, with size 2 to 200 microns, and their interconnections are accurately determined during the project stage. The concavities penetrate deep inside the implant body down to 200 microns, creating pits and pores that are colonized by bone cells.

Another extraordinary feature, demonstrated by the studies carried out by Prof. R. Sammons at the University of Birmingham is the isoelasticity of the surface, that has a Young module which is quite the same as the bone one, while the implant core maintains the characteristic Young module of titanium, as for ASTM standards.
The isoelasticity gives the implant a structure very close to the natural tooth, more similar than any other implant on the market.
In vitro studies carried out by Prof. R. Sammons at the University of Birmingham (UK) and by Prof. G. Papaccio at the II University of Naples (Italy), the researches carried out by the Universities of Varese and Chieti (Italy) and clinical-histological trials carried out on animals and humans by Prof. J.A. Shibli at the University of Guarulhos, Sao Paulo (Brazil), have demonstrated the capability of these implants to accelerate bone healing, thus improving a faster osseointegration compared with the traditional surfaces on the market, and allowing bone formation (down to 200 microns) inside the isoelastic porous structure.
