The macroscopic structure of bone has been traditionally studied through x-ray radiography or tomography. However, the resolution limits these techniques do not enable reconstruction composite architecture at nanometer level. Compared with histomorphometry, micro-CT shown its efficiency in providing nondestructive and rapid 3D images measurements on microstructure. Micro-CT higher achieved synchrotron radiation-based computed microtomography (SRμCT).The aim this study was a histological SRμCT analysis 2 porous titanium implants.Two direct laser metal forming implants were inserted posterior maxilla patient retrieved after months. One treated to obtain thin ground sections, whereas other underwent evaluation.The results, showing that implant surface presented superficial debris particle inclusions surrounding tissue close area, confirmed by investigations.SRμCT allowed high good sample penetration depth focus an evaluation relative arrangement structures cannot be determined 2D imaging.
