AB  - The aim of the present study was to report the main topographical and chemical 
      changes of a failing 18-year in function retrieved acid-etching implant in the 
      micro- and nanoscales. A partially edentulous 45 year old rehabilitated with a 
      dental implant at 18 years of age exhibited mobility. After careful examination, 
      a 3.25 x 13-mm press-fit dental implant was retrieved. Scanning electron 
      microscope (SEM) analysis was carried out to study topographical changes of the 
      retrieved implant compared with an unused implant with similar topographical 
      characteristics. Moreover, X-ray photoelectron spectroscopy (XPS) analysis was 
      used to study the surface composition of the retrieved failing implant. Clear 
      changes related to the dual dioxide layer are present as visible in >/=x500 
      magnification. In addition, it was found that, for the retrieved implant, the 
      surface composition consisted mainly of Ti2p, O1s, C1s, and Al2p. Also, a 
      meaningful decrease of N and C was noticed, whereas the peaks of Ti2p, Al2p, and 
      O1s increased when analyzing deeper (up to x2000s) in the sample. It was shown 
      that the superficial surface of a retrieved press-fit dual acid-etched implant 18 
      years after placement is impaired. However, the causes and consequences for these 
      changes cannot be determined.
