Mandibular hypoplasia with curvilinear distraction.

Mandibular distraction with intraoral curvilinear distractor is an effective procedure for lengthening the mandibular corpus and ramus dimensions. Mandibular distractor is valuable for the treatment of hypoplastic mandible. The aim of this article was to describe the treatment of a patient with hypoplastic and severely retrognathic mandible resulting from isolated Pierre Robin sequence, by means of curvilinear distraction osteogenesis followed by fixed orthodontic treatment. As a result, the curvilinear path of distraction can form a new mandibular angle and bring the mandible significantly forward. Attention should be given for the stability of the treatment results.
