In collaboration with the MATEIS laboratory of INSA Lyon, three LMI research teams have demonstrated the value of a fibrous calcium phosphate coating to prevent the loosening of implants. Apart the convincing biological results, the article presents deposits of bioactive coatings on implants with a non-planar surface, such as dental implants. The study was funded by the French National Research Agency (project ANR-17-CE19-0004-03).
