Razdolsky developed a series of tooth-borne and hybrid ROD devices in which the anteriorly activated distraction mechanism can be attached to stainless steel crowns or mini plates by removable attachments (Razdolsky et al., 1998). In addition, he designed a special laboratory instrument allowing individually preprogrammed fabrication of the distraction frame along a predetermined axis of distraction based on preoperative records. After the appliance is cemented to the teeth and/or fixed to the bone, the distractor frame is removed and the corticotomy is performed, followed by replacement of the distractors.
