The center of resistance (CR) of a tooth is the point of concentrated resistance to movement. In free space, CR is the center of the tooth which happens to correspond to the center of gravity of the tooth.
When the tooth is in the mouth, the tooth is embedded in bone. The CR now shifts to the center of the portion of the tooth embedded in the bone.
