Methods and devices for bone surgeries

A method of designing at least one of a patient-specific bone cutting guide, a patient-specific bone graft placement guide, a patient-specific bone plate placement guide, and a patient-specific bone plate, the method comprising:

• identifying a first abnormal aspect of a virtual, patient-specific 3D surface representation of a patient's craniomaxillofacial bone, to be replaced as part of a surgical procedure, using surface contours of the virtual, patient-specific 3D surface representation;
• comparing a virtual, patient-specific 3D surface representation of a donor bone with a virtual, patient-specific 3D surface representation of a craniomaxillofacial bone graft model to identify a virtual donor graft section of the donor bone;
• generating a tangible, patient-specific bone cutting guide using a virtual, patient-specific craniomaxillofacial bone graft placement guide that embodies surface contours matching surface contours of the virtual donor graft section.
