implant news2 EAO Annual Scientific Congress 2015 · 24 September A research project on chronic oral infections, led by Prof. Gun- nel Svensäter from Malmö Uni- versity, has been recently awarded a grant of SEK12 million (€1.3 million) by the Swedish Knowledge Foundation. The re- searchers aim to develop new clinicaltoolstodiagnoseandtreat such infections. In a statement, the foundation acknowledged that research on chronic oral infections offers im- mense potential and could be of considerable benefit for patients, the dental care system, industry and society in general. To date, there are no reliable methods in dental care for identifying individ- uals with an increased risk of seri- ous tooth and implant infections. Therefore, the Malmö researchers are targeting the development of new clinical tools in order to en- hance diagnosis and treatment of such conditions. “We are searching for proteins that exist in biofilms around teeth and implants. The proteins can originate either from bacteria or fromhumancells.Iftheseproteins couldbefounditwouldbepossible to identify the site as a potential source of infection and treatment could be initiated at an early stage,”Svensäter,ProfessorofOral Biology at the university’s Faculty of Odontology, said. The lead researcher further- more foresees potential financial benefits from developing diagno- sis tools that could be used world- wide, for both the health care sys- tem and companies. “The problem we are endeav- ouring to solve is significant and exists on a global scale. Some 10 percentoftheSwedishpopulation could experience serious prob- lems involving chronic infections that could result in them losing their teeth. The scenario is much the same throughout the rest of the world,” she said. The four-year project, which brings together mi- crobiologists, cellular biologists, chemists and clinical experts, among others, will focus on first finding protein markers in labora- tory experiments and later pro- ceed to clinical studies with pa- tients. According to Svensäter, the re- search project has been in the planning for a number of years. “We now have the right research group and the right companies in place and we are extremely pleased.” Adding to donations of about SEK12millionbycompanies,aswell as the university’s contribution of SEK6 million (€0.6 million), the grant by the foundation brings the project’s total budget to SEK30 mil- lion(€3.2million). The Knowledge Foundation is a funding body for universities and servestostrengthenSweden’scom- petitiveness. Since its formation in 1994, the foundation has invested about SEK8.7 billion (€942 million) in more than 2,500 projects.

AD150087INT AD An examination of biologically failed dental implants conducted by researchers in Israel has found that more than 60 per cent of these implantsshowedsignsofmechani- calflaws,suchascrack-likedefects and full cracks. In publicising these results, they aim to encour- age dental implant manufacturers and dentists to find ways to reduce the structural damage that occurs whenametalissubjecttorepeated applied loads. In the study, the researchers from the Technion—Israel Institute of Technology in Haifa examined 100 discarded dental implants, which had been extracted owing to peri-implantitis, made of a tita- nium alloy and commercially pure titanium using energy disper- sive X-ray analysis and scanning electron mi- croscopy. They found mechanical defects in 62 per cent of the speci- mens. In addition, the inspection showed that the pure titanium im- plants had more cracks than did the titanium alloy implants. “Embedded parti- clesappeartobelinked to the generation of surface defects that evolve into full cracks,” explained Dr Keren Shemtov-Yona,whocon- ductedthestudyaspart ofherMasterofScience degree. Furthermore, the wear and tear of daily use also seem to contribute to- wards the potential of manu- facturing flaws to develop into cracks and subsequently lead to failure of the material, she said. It was also found that the width and length of the differ- entimplantsinthisstudywere not correlated with the ob- served defects. Shemtov-Yona is now aiming to conduct fur- ther studies to investigate the reasonsforthedevelopmentof cracks to determine whether the causes lie in manufactur- ing, use or both.
