Abstract
In the present work, the generation of Laser Induced Periodic Surface Structures (LIPSS) by using femtosecond laser source is investigated in the surface texturing of Ti grade 5 dental implants. The proposed procedure permits a fast treatment of dental implants characterized by complex shape through the combined and synchronous use of a galvo scanner and of workpiece movements. The obtained surface micro- and nanostructures are characterized from a morphological point of view while in-vitro essays are performed to evaluate cellular proliferation. The results indicate the effectiveness of the LIPSS as method to increase cell viability and the efficiency of the proposed procedure to treat complex geometries as dental implants.
Highlights
The manufacturing process of commercial titanium alloys based dental implant made use of advanced CNC single and multi-spindle turning centers (Swiss lathes)
Clinical studies indicates that early implant failures, commonly attributed to poor wound healing, inflammation and postoperative infections, are strongly reduced for implants with rough surface implants compared to smooth one [2]
Laser texturing [6] is a well-known and promising method and, in the last years, the use of ultrashort laser sources has offered new possibilities of treatment based on the generation of Laser Induced Periodic Surface Structures (LIPSS)
Summary
The manufacturing process of commercial titanium alloys based dental implant made use of advanced CNC single and multi-spindle turning centers (Swiss lathes). These manufacturing lines guarantee high repeatability, high throughput rate and, at the same time, high flexibility to produce dental implants with complex geometries [1]. When the laser operates with pulse duration from femtoseconds to few picoseconds and in regime of strong ablation, these structures appear as reliefs and grooves on metals, dielectric as well as on polymers They are marked by a periodicity L well below the dimension of the laser focal spot
