Biological Performance of Chemical Hydroxyapatite Coating Associated With Implant Surface Modification by Laser Beam: Biomechanical Study in Rabbit Tibias

Skeletal stem cell and bone implant interactions are enhanced by LASER titanium modification

“…LASER irradiation has been shown to be a promising method for Ti surface treatment, increasing the Ti surface area, wettability and, critically, offering a high degree of surface purity at relatively low cost [11,12,19]. Furthermore, studies with LASER-modified materials implanted in rabbit tibias and subsequently presenting high removal torques [11,12,19] and properties that favour cell adhesion and proliferation make this an attractive approach [10,20]. We have previously shown that the topography of a Ti LASERmodified surface displays distinct topographies including a surface roughness with an appearance comparable to a "cauliflower" morphology that provide enhanced wettability and surface area [6].…”

“…As recently detailed in a number of studies, LASER treatment appears to provide a promising method for Ti implant generation, resulting in enhance and rapid onset of osseointegration [6,10,11,12,13].…”

Reliability evaluation of alumina-blasted/acid-etched versus laser-sintered dental implants

“…These studies reported an increase in removal torque for the laser-treated titanium implants compared to implants that were fabricated by machining [35][36][37]. Such results are likely due to the higher surface roughness and thereby mechanical interlocking between bone and laser-sintered/ textured implants compared to implants that are first machined and then textured by a variety of methods (Coelho et al 2008).…”

Bacterial interactions with biomaterials metallic surfaces

“…The machined titanium was used as control. And, another one, considered rough surface, received a laser treatment that was carried out by means a pulsed Nd:YAG laser (DigiLaser, DML-100) 11 , as seen in optical images in Figures 1 and 2. Titanium discs were cleaned in ultrasonic bath with mild detergent solutions distilled-water, acetone, ethanol and ultra pure water and dried at room temperature.…”

“…The coupons surfaces were observed by scanning electron microscopy (JEOL-JSM, T330A-Japan), and the wettability of the surfaces was determined by means of goniometer OCA-20 Contact Angle System (DataPhysics Instruments) at room temperature. A profilometer (Mitutoyo SJ-301) was used to measure the surface roughness and results were expressed in µm as average roughness R a (arithmetic mean of sampling area roughness) 11 .
