Figure 3: Intraoral custom-made distraction osteogenesis device for mandible. Components: The various components of distraction assembly suggestive of functions they carry out (1) Sleeve for the distraction screw (2) Fixed block comprising of three-hole stainless steel triangular bone plate fixed to the medial fragment with the help of three 2mm monocortical screws (3) Movable block also comprising of three hole stainless steel triangular bone plate fixed to the distal fragment which moves along the threaded rod with the fragment at the time of distraction (4) Threaded central rod each thread of the rod has the pitch of 0.5mm, therefore one turn of 360degrees brings about distraction of 0.5mm. The appliance is designed in such a way that a maximum of 25mm distraction is achieved (5) Two guiding supporting rods one above and one below the central threaded rod in parallelism with the central threaded rod (6) Three hole stainless steel triangular bone-plate used for fixation of distraction appliance (7) Stabilizing plate holding the threaded rod and the two guiding plates together at the posterior end of the assembly (8) A special custom made screw driver is manufactured to fit in the slot of the distraction screw
