Laser Surface Structuring of Commercial Pure Titanium
Keywords:Laser surface structuring, commercial pure titanium, dental implant.
Aim This Study existent laser surface structuring of commercial pure titanium (Ti) grade II dental implant
,surface structuring of the titanium implant expected causing decrease the time of implant healing and
accelerated the periimplant bone formation. So the present study aimed was in vitro evaluation of commercial
pure titanium when subjected to two laser surface structuring (dot and groove) in different laser scans and
comparing with titanium surface that not subjected to any surface structuring (control) by using optical
microscope, scanning electron microscope (SEM) and X-ray Diffraction analysis (XRD) test.
Materials and Methods: CNC fiber laser machine laser was used for performing the structuring on the
surface of the commercial pure titanium (CP Ti) disks and then analyzed with the control group by optical
microscope, SEM and XRD test. The study groups are: polished CP Ti (control); (5, 15 and 25) CP Ti with
dot design laser scans; (5, 15 and 25) CP Ti with groove design laser scans.
Results the optical and SEM results showed a uniform homogenous structure on the surface of the CP Ti for
the two design of all tested laser scans (5, 15 and 25). The XRD results show an increasing in the titanium
oxide layer for the disks with laser structuring comparing to the control one which predicted to increase
titanium osseointegration while maintaining biocompatibility characteristics of the CP Ti.
Conclusions: CNC fiber laser machine are successful method for CP Ti surface structuring. For both laser
surfaces structuring design, the 25 laser scan showed more promising results follow by 15 laser scan then 5
laser scan and lastly the control group.
