Abstract
This study investigated the effect of initially light and gradual increases in force on tooth movement using the attractive force of magnets in an experimental rat model. The distance between the magnets incrementally decreased from an initial light force in the experimental group, in contrast to no tooth displacement in the control group. There were significant differences in the number of osteoclasts and in the relative hyalinized area on the pressure side of the periodontal tissue between the control group and the experimental group. The application of gradual incremental increases in force induced effective tooth movement in rats, and recruitment of osteoclasts and inhibition of hyalinization.
