Técnicos de la Tecnología de NanoSPM junto a investigadores de odontología de la UB han colaborado en un estudio sobre implantes de Titanio (Ti) en el campo de la odontología, para evaluar el posible uso de diferentes métodos para tratar la pre-implantitis y modificar adecuadamente la superficie para la posterior re-osteointegración del hueso en el implante ya tratado. El estudio se ha realizado con el equipo de Microscopia óptica Avanzada DCM3D de la Tecnología de NanoSPM y se ha complementado con imágenes de AFM y SEM del mismo centro. El estudio ha sido publicado en el science lab de LEICA, siendo el primer artículo de metrología superficial que publican. El resumen del artículo es el siguiente: "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." | |
