Fig. 1

The method of determining a single implant cantilever (mesiodistal cantilever). If the difference between the length of “b” (distance from the midline to the longest part of the mesial) and the length of “a” (distance from the midline to the longest part of the distal) is greater than 2 mm, it is considered a mesiodistal cantilever. In this figure, fixture fracture occurred at the bottom of the prosthesis fixation screw and marginal bone loss were observed up to this site
