The Development of Dental Implant-Controlled Surface Roughness: A Dental Technique

Introduction: the production of a dental implant with controlled surface roughness was thought to facilitate basic studies of the effects of laser groove dimensions and geometry on the adhesion of cells to titanium surfaces. Materials and methods: The proposed technique utilized pulsed ultraviolet laser to engrave 10 µm micro-grooves on machined surface of custom-made Ti-6Al-4V dental implants, and used a scanning electron microscope (SEM) for visual evaluation of the produced grooves using the linear measurement tool of the SEM software. Results: The technique presented provided a step-by-step procedure to produce dental implant surface with a controlled surface roughness of 10 µm micro-grooves. Conclusion: the proposed technique is thought to be a reliable method to produce uniform 10 µm micro-grooves on the machined surface of custom-made Ti-6Al-4V dental implants which are thought to improve the cellular adhesion to the implant and yield a stronger bone-implant interface than that provided with random implant surface roughness.
