Tècnics de la Tecnologia de NanoSPM juntament amb investigadors d'odontologia de la UB han col·laborat en un estudi sobre implants de Titani (Ti) en el camp de l'odontologia, per a avaluar el possible ús de diferents mètodes per tractar la pre-implantitis i modificar adequadament la superfície per a la posterior re-osteointegració de l'os en l'implant ja tractat. L'estudi s'ha realitzat amb l'equip de Microscòpia òptica avançada DCM3D de la Tecnologia de NanoSPM i s'ha complementat amb imatges de AFM i SEM del mateix centre. L'estudi ha estat publicat al science lab de LEICA, sent el primer article de metrologia superficial que s'hi publica. El resum de l'article és el següent: "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." | |
