Enhancement the Biological Behavior of Titanium Dental Implants by Laser Pulses Treatment

Abstract

The long-term success of dental implants largely depends on rapid healing with safe integration into the jaw bone. Geometry and surface topography are crucial for the short and long-term success of dental implants. This work aim to enhancing clinical performance of titanium dental implants by laser Pulses treatment to provide bone in a faster and improved osseointegration process. The results show that using different manufacturing processes (machining and powder technology) produced topographical differences. The topographical change observed from powder technology method was more than the machined one. Also Strong titanium oxide layer was observed after laser pulsed resulted in improving surface roughness and topography and it was the method of choice for complex surface geometries providing energy focused on one spot especially in the inside of implant thread. The release of Ti ion rise in first three days and after that released of Ti ions begins to stabilize after laser treatment. Finally, the histological view of implant samples after 4weeks of implantation, showed active bone formation in all implant surface which give clear indication of tissue acceptance and the appearance of mature bone was observed after laser treatments at short implantation periods.
