Molar intrusion causes counter-clockwise mandibular rotation and anterior open bite closure. Many techniques have been used to intrude maxillary and mandibular teeth by various mechanisms, such as passive posterior bite-blocks, active vertical correctors, functional appliances, and multi-loop edgewise arch wire techniques. Anchorage systems have included high-pull head gear, and recently, miniscrew implants.
