DISTRACTION APPARATUS FOR SUBAPICAL OSTEOTOMY AND VERTICAL SEGMENT DISTRACTION AND RIDGE AUGMENTATION

摘要

An apparatus (60) for use in dental base regeneration has a rotatable shaft (63) supported by tooth fixing members (61, 62) supporting ends of the shafts for rotatably supporting the shaft on teeth of the mandible or maxilla. A bone section engagement wire (170) is connected to the rotatable shaft and is inserted into a bone section resulting from osteotomy. Rotation of the shaft (63) thus allows the bone section to be gradually vertically distracted to allow tissue to regenerate and gradually augment the bone ridge of the maxilla or the mandible.
