Scientists from the European project Laser4Surf are currently developing a multi-beam optical module to treat the metallic surfaces of dental implants to achieve the best cell adhesion and antibacterial properties. “Surface treatment allows either a bigger surface in contact between the implant and the bone or a better affinity regarding the chemical interaction between the cell and the implant,” explains Marilys Blanchy, a research & development manager at Rescoll, one of the project’s partners. Rescoll is a technology centre, specialised in polymer science, adhesive coating and medical devices, based in Bordeaux, on France’s Atlantic Coast.
