Technicians from NanoSPM Technology together with dental researchers from the UB have collaborated on a study on Titanium (Ti) implants in the dentistry field, to evaluate the possible use of different methods for treating pre-implantitis and modify properly the surface for the further re-osseointegration of the bone in the already treated implant. The study was conducted with the Advanced Optical Microscopy device DCM3D from the NanoSPM Technology and has been complemented with AFM and SEM images from the same center. The study has been published in the LEICA science lab and it will be the first real scientific contribution for Science Lab on Surface Metrology. The abstract of the article: "Titanium (Ti) alloys are biocompatible materials which are often used for human implants, especially in dentistry. For this study, different types of odontological (dental) treatments for peri-implantitis, an infection of the gum and dental tissue around the implant, were performed on a Ti-6Al-4V (TAV) alloy, typically used for implants, to study the effect on its surface roughness and chemistry. The motivation of this investigation is to better understand if these commonly exploited dental treatments can help improve the implants ability to re-osseointegrate, i.e. the tendency of bone to re-integrate into the implant material, during healing. The effects of various odontological treatments, such as ultrasonication, jet polishing, laser illumination, and biochemical and chemical exposure, on the Ti alloy surface roughness and chemistry were investigated. When applied strategically, these dental methods may prove useful in improving the chances for re-osseointegration of Ti alloy implants after successful treatment of peri-implantitis." | |
