GALLEGOS-SALAZAR, Aylin  and  VIDALON-CASTILLA, Jose. Treatment of malocclusion class II-1 with mini-implants: a case report. Rev. Estomatol. Herediana [online]. 2015, vol.25, n.1, pp.52-60. ISSN 1019-4355.

Over time different devices like the mini-implants have been designed to optimize the anchorage. The anchorage is essential for orthodontic treatment, as the correction of malocclusion Class II division 1. We present a 22 years old patient, midbrain, dolicofacial, convex, malocclusion Class II-1 by maxillary protrusion, maximum anterior retraction with mini-implants was performed using a medium pull vector, this is used when little or no alteration of the occlusal plane with a whole body motion of the upper front teeth is needed. The length of the hook was 8mm and the insertion of the mini implant was 8mm from the union cement enamel (UCA), so that the force vector passes through the center of rotation of the anterior segment (located between the lateral incisor and canine to approximately 7mm on the cervical area).

Keywords : Orthodontic; retraction; anchorage.
