Interrami intraoral Kirschner wire fixation (IRIF) technique is presented as new conservative successful indirect rigid fixation utilized for the reduction and fixation of edentulous/atrophic mandible fractures. This technique is carried out under local anesthesia without the need for open reduction internal fixation, which can lead to a compromise in the blood supply of fracture region. It is also quicker, easier, requires fewer postoperative visits, and cheaper than small or large bone plate fixations.Five edentulous mandibular fractures, 2 of them atrophic, 2 non-atrophic, and 1 partial edentulous, were successfully treated. In all cases, the IRIF technique was utilized to establish an indirect rigid fixation using horseshoe-shaped Kirschner wire with a 2-mm diameter. No complication was reported during these cases. This technique prevails over the Gunning splint and external edentulous fracture fixation techniques as it provides adequate fracture site stability, is more comfortable, and is better tolerated for a longer period of time by the patient. In addition, there are fewer complications caused by malunions from direct intraoral or extraoral small and large plate fixation techniques. Other advantages of the IRIF technique are that it enables the mandible to function as a single unit and preserves its function and anatomical position immediately after surgery. In contrast, the Gunning splint acts only to preserve the balance of a single segment's position.
