3D Printing Personalized Titanium Plate
The cutting guides were placed onto the planned position. The cutting guides also worked as the drilling guide. Several screw holes were drilled using the predetermined screw holes on the guides. The osteotomy / ostectomy then start. Next, the 3D printing personalized maxillary fixation plates were adapted to reposition the Le Fort I segment to the planned position. The screw holes on the bones prepared by the cutting guides were used as the bony reference. The personalized plate was first firmly installed on the maxilla above the osteotomy line by aligning the corresponding screw holes on the plate to the bone. Afterwards, the position of the osteotomized Le Fort I segment was adjusted till all the remaining corresponding screw holes on bone and plate were aligned.
