• The stages of virtual surgical planning and fabrication of patient specific titanium eminoplasty will be designed my Mimics 15 program.
• Once designed, the virtual design and surgery will be planned on a computer model where vital anatomical structures could be identified and thus could be avoided during surgery.
• After obtaining all the dataset needed from the CT scan, the collected data will be sent to the Egyptian soil, water and environmental institution for manufacturing, packing and sterilization of the patient specific titanium eminence.
• The patient specific titanium eminence will be inserted and secured with two to three screws of individual lengths according to the virtual plan.
• Functional mandibular movements were reproduced to confirm absence of subluxation and checked for interference and any required adjustments made.
• A multilayer closure of the incisions will be accomplished using Vicryl sutures.

• A safety distance of 5 mm will be maintained from the apex of the mandibular incisor and inferior mandibular border, the mental foramen, and permanent canine follicle.
• One corticocancellous bone block with a maximum depth of 4 mm will be removed by mallet and chisel based on the recommendation that bone from the chin should be harvested at this maximum depth, compatible with the course of the mandibular incisive nerve canal on CT scans.
• After removal of bone from the chin, the intervening bone struts will be removed using rongeur forceps and used as an additional bone graft.
• The bone removed will be trimmed and contoured in a wedge form to be used as an inter-positional graft in the previously down fractured articular eminence to act as an obstacle in front of the mandibular condyle to prevent its hyper movement.
