The goal of this clinical trial is to learn whether using three dimensional (3D)-printed anatomical models improves the informed consent process for participants undergoing orthognathic surgery. The trial also explores how these models affect participants understanding, anxiety, satisfaction, and communication with the surgeon. The main questions it aims to answer are: * Do 3D-printed anatomical models improve participants understanding of their jaw condition and the surgical procedure? * Do they reduce participants anxiety before surgery? * Do they enhance overall participants satisfaction and the physician-patient relationship? Researchers compares participants who received standard two dimensional (2D) imaging and verbal explanations with those who received the same information plus 3D-printed jaw models. Participants: * Scheduled for double- or triple-jaw orthognathic surgery * Randomly assigned to receive either traditional 2D education or the 3D-printed model intervention * Complete a validated questionnaires assessing understanding, anxiety, satisfaction, and doctor-patient communication
