Laser microgrooving and resorbable blast texturing for enhanced surface function of titanium alloy for dental implant applications.

Long-term dental implant success is dependent on biocompatibility and osseointegration between the bone and the implant. Surface modifications such as laser-induced microgrooving which increase contact area can enhance osseointegration by establishing and directing a stable attachment between the implant surface and peri-implant bone. The objective of this study was to evaluate pre-osteoblast proliferation, morphology, and differentiation on titanium alloy (Ti64) surfaces-Laser-Lok (LL), resorbable blast textured (RBT), and machined (M)-compared to tissue culture plastic (TCP) control.
