Mini-implant anchorage has been proven to be an effective therapeutic strategy in treating various kinds of malocclusions. The most common position for mini-implant anchorage is on the upper posterior area. It is not only because the clinical requirements in anchorage reinforcement in the upper arch but also because of the more favorable anatomical situations of attached gingiva and surrounding movable mucosa. The previous use of mini-implant anchorage in the lower posterior area are either interdental miniscrews or exo-dentitional miniplate. The interdental miniscrews are primarily for maximal anterior retraction and vertical control. It is more comfortable for the operator to insert the miniscrews in the attached gingival area, but it is not suitable for whole dentition distalization because of the possibility of interference of root movement on the miniscrews. The miniplates were fixed by 2 mini-screws in the exo-dentitional bone and were extended to the proper position for anchorage. The whole dentition movement is no longer restrained by the mini-implant itself. However, the need of flap operation makes the patients suffering from the postoperative swelling. The authors will illustrate the use of exo-dentitional miniscrews in the mandible for treating the Class III malocclusion by full lower dentition distalization in a nonextraction approach.
