[Presurgical orthodontic preparation of skeletal Class II by means of a bone anchorage with an osteosynthesis wire: a clinical case].

Abstract

The aesthetic and functional success of mandibular advancement surgery often depends on the quality of the orthodontic preparation that preceded it. In order to be optimal, this preparation must try to reproduce a class II malocclusion equivalent to the sagittal skeletal discrepancy, to allow a surgical procedure of sufficient amplitude. The aim of this article is to present, thanks to a clinical case, a new mandibular posterior anchorage device, called Abalakov, used in the context of these preparations. The modalities of placement and use of this simple osteosynthesis wire, placed in the anterior part of the ramus, are exposed step by step, until the final result is obtained. The advantages and effectiveness of the technique are then discussed and compared with other treatment alternatives. It can be concluded that this new device is a simple, comfortable, inexpensive and above all reproducible and highly effective means of distalization of the mandibular arch, with clear uprighting of the incisors.
