F. A vertical hole is place through the transport fragment to accommodate the threaded rod of the distraction device. A 2mm diameter drill is used. The crestal mucosa is not reflected. Drilling is performed transmucosally. An implant contra-angle drill revolving at slow speed is best for this operation. Drill lengths of 15 and 20 mm are often needed. Drill extensions may be needed if access is limited by the adjacent teeth.

F.

G. The components of the distraction device are assembled in situ. The threaded rod is pushed through the vertical hole until it becomes visible in the horizontal component of the osteotomy. The transport plate is introduced into the osteotomy and rod threaded through it. The stabilizing plate it then engaged into the end to the of threaded rod. If the bone on the stable side of the osteotomy is very dense, placement of a stabilizing plate may not be necessary. The stabilizing plate may be omitted if adequate stability of the device has been achieved by resistance of the bone alone. Usually this is only possible in the mandibular anterior region.

G.

H. After the components of the distraction device are positioned, they become essentially self-retaining. To prevent movement of the device during activation, the extensions of the transport and stabilizing plates are bent to the contour of the bone. In the example, the plates are being bent by pressure from a serrated amalgam plugger. Microscrews are then placed to secure the plates.
