Orthognathic surgical technique of segmental osteogenesis distraction of the anterior mandible alveolar process (front-block) was introduced by Triaca and al. in 2001 [2Triaca A, Antonini M, Minoretti R, Merz BR Segmental distraction osteogenesis of the anterior alveolar process J Oral Maxillofac Surg 2001 ;  59 (1) : 26-34 [cross-ref]

A genioplasty plate was used as a bone-borne distractor. The main point here is that distraction depends on two distraction vectors, a dental one and an alveolar one. It provides good stability and controlled segmental osteogenesis translation and allows sufficient alveolar segmental transport without loading the teeth too heavily.
