Face Adjustment Image System Using 3D Skeletal Superimposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual simulation programs for face correction operations, such as plastic surgery and orthodontic treatments, struggle to accurately predict the change in facial appearance due to their reliance on two-dimensional modifications, which can differ from the actual post-operation results, especially when osseous tissues are involved.
Innovation Solution
A method and system that superimpose a cephalometric image with a three-dimensional facial image to predict the transformation of soft skin tissues based on skeletal changes, allowing for precise display of the predicted facial image on a screen, enabling accurate planning and communication between medical staff and patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional image modification is used to predict facial appearance change, then the operation plan can be set up during surgery counseling, but the predicted facial image differs from the actual appearance after the operation
Solution Approach 1:
The patent transitions from two-dimensional image modification to three-dimensional facial image processing. By acquiring and processing 3D facial images, the system can accurately predict facial appearance changes after orthodontic treatment or surgery, resolving the inaccuracy inherent in 2D methods while maintaining operational feasibility through computer-based visualization.
2Adaptability or versatility
If two-dimensional image modification is used, then the virtual simulation program can be provided to medical staff, but it is difficult to set up the plan and method of the operation when osseous tissues are involved
Solution Approach 1:
The system uses three-dimensional facial images to create virtual simulations that accurately represent complex osseous tissue changes. This 3D approach allows medical staff to visualize and plan surgical or orthodontic procedures involving bone structures, making the operation planning process feasible and intuitive despite the complexity of osseous tissue involvement.
Solution Approach 2:
The patent introduces a computer-based virtual simulation system as an intermediary between the medical staff's planning intentions and the actual surgical outcomes. This intermediary process allows for accurate visualization and adjustment of treatment plans before actual surgery, facilitating better decision-making for complex osseous tissue corrections.
3Productivity
If prediction of facial change is performed simply based on two-dimensional modification, then the process can be completed, but the predicted appearance may differ from the actual appearance after orthodontic treatment
Solution Approach 1:
The patent employs three-dimensional facial image acquisition and processing to maintain both efficiency and accuracy in predicting facial appearance changes. The 3D digital modeling allows for rapid virtual manipulation and prediction while achieving high precision in representing actual post-treatment appearance, unlike 2D methods that sacrifice accuracy for speed.

AI summary
The present invention relates to a method and system for providing a face adjustment image, the method comprising the steps of: (a) generating a matched image by superimposing a cephalometric image having a cranium image of a patient whose face is to be corrected with a three-dimensional facial image of the patient; and (b) displaying a predicted facial image on a screen by transforming soft skin tissues of the face according to the skeletal change in the cephalometric image. According to the present invention, the change in the soft skin tissues and the predicted facial image are displayed on a screen of a computer, a terminal or the like based on the skeletal change in cranium, teeth, prosthesis or the like supporting the soft skin tissues. Therefore, the change in the soft skin tissues can be predicted, thereby increasing the accuracy of a face correction operation, making it more accurate and convenient to plan the operation, and enhancing communication between the patient and medical staff.
