| Research Abstract |
Effects of initial loading time on stress distribution in bone around dental implant were assessed by finite element analysis. The stress values in the low-density cancellous bone models under early loading were greater than those under conventional loading. These findings suggest that implant placement at low-density cancellous bone under early loading could result in bone resorption due to an overload. In the animal experiment, peri-implant bone resorption due to an overload was observed.
