Orthodontic miniscrews are temporary anchorage devices that allow orthodontists to expand the scope of biomechanics. However, these miniscrews do not osteointegrate and are subject to failure. Various methods have been tried to decrease the failure rate: eg, increasing thread count or size, increasing the length of the miniscrew, and changing the geometry of the miniscrew. Studies have shown that failure rates are more closely related to the location of placement and the quality of bone. The aim of this randomized controlled trial was to compare torque recordings at insertion time and 1 week after placement between immediately loaded orthodontic miniscrews and an unloaded control group.
