 | | Distraction was introduced first by Codvilla nearly a hundred years ago and was subsequently popularized during the 1940s by Ilizarov, who developed a single-stage procedure to lengthen long bones without the use of grafting material. |
 | | Finally, appliance rigidity during distraction and consolidation is a critical element to ensure that bending or shearing forces do not result in microfractures of the immature columns of new bone within the regenerate, which lead to focal hemorrhage and cartilage interposition. |
 | | Preoperative considerations for mandibular distraction include (1) the preexisting shape of the lower jaw (eg, ramus height, body length, gonial angle), (2) its position relative to the maxilla and cranial base, (3) the presence of asymmetry and mandibular and occlusal plane angles, and (4) the occlusion (eg, anteroposterior relationships, transverse relationships, open bite deformities). |
