Growing class III patients with maxillary deficiency may be treated with a maxillary protraction facemask. Because the force generated by this appliance is applied to the teeth, the inevitable mesial migration of the dentition can result in anterior crowding, incisor proclination and a possible need for subsequent extraction therapy. The Hybrid Hyrax appliance, anchored on mini-implants in the anterior palate, can be used to overcome these side-effects during the facemask therapy. In some class III cases, there is also a need for subsequent distalization after the orthopaedic treatment. In this paper, clinical application of the Hybrid Hyrax Distalizer is described, facilitating both orthopaedic advancement of the maxilla and simultaneous orthodontic distalization of the maxillary molars.
上颌骨发育不足的生长发育期III类患者可用上颌前牵引面罩进行治疗。由于该矫治器产生的力作用于牙齿，牙列不可避免地向近中移动会导致前牙拥挤、切牙前倾，可能还需要后续的拔牙治疗。Hybrid Hyrax矫治器固定于腭前部的微型种植体上，可用于在面罩治疗期间克服这些副作用。在一些III类病例中，正畸治疗后还需要进行后续的磨牙远移。本文描述了Hybrid Hyrax远移矫治器的临床应用，它有助于上颌骨的正畸前徙以及上颌磨牙的同步正畸远移。
