Abstract
The damage analysis of the titanium dental implant fracture was done with using electron microscopy. The fracture occured 33 months after the single crown prost hodontic reconstruction. The fissure of the fracture took place at the implant neck and shaft border. The shaft was also marked. Additionally the line of fracture overlapped the end of holding screw. It was pointed out that sandblasting procedere leads to the formation of sharp, cuneiform notches that can cause micro-cracks and subsequent fractures of the implant.
