A method for repositioning bone portions in facial surgery, comprising: creating a pre-operative model of the bone; virtually resecting the bone to define the ideal position of the bone fragments; producing a custom-made implant and drilling guide based on the modified model; and using the guide to drill precise screw holes in the bone fragments, ensuring accurate alignment and repositioning of the bone portions.
