And there are no differences in bone absorption among different implant systems, or between mesial and distal regions of the same implant. After that, the measurement method is discussed, and it is concluded that the results of the research are consistent with the truth. And then, the possible causes and settlements of peri-implant bone absorption are discussed.

Results:When wide-diameter implant or two-implant were used to replace single mandibular molar, the stress of implant-bone interface was much lower than that of standard-diameter implant restoration. Comparison between wide-diameter implant and two-implant replacement showed that the former created lower stress. The difference was more obvious under oblique loads.
