Radiology image of porous corundum ceramic implants into bone

Radiographs of porous and compact-porous corundum ceramic implants into patients' bone were pointed out. Especially, the changing details of X-ray photographs were taken in accounts as the consequence of the period of time from date of the implant insertion. The ingrowth of the bone into the implant pores blurs its contours, on the radiograph, and in part of examined patients, the disappearance of the ceramic-bone boundary was observed. (author)
