A novel 3D printing technique creates custom splints for orthognathic surgery. This method integrates virtual planning with physical models for precise surgical outcomes.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Dental Technology

Background:

  • Orthognathic surgery corrects jaw deformities.
  • Traditional splint fabrication can be time-consuming and may lack precision.
  • Advancements in 3D imaging and printing offer new possibilities for surgical planning and device fabrication.

Purpose of the Study:

  • To present a new technique for producing patient-specific splints for orthognathic surgery using 3D printing.
  • To demonstrate the integration of 3D data acquisition, virtual planning, and 3D printing for splint fabrication.

Main Methods:

  • Acquire 3D data using computed tomography (CT) or cone-beam computed tomography (CBCT).
  • Perform virtual repositioning of jaws and combine with scanned plaster models to reduce artifacts.

  • Design a virtual splint, subtract tooth impressions, and 3D print the final splint.

    • Main Results:

    • The technique allows for precise virtual repositioning of the jaws based on patient-specific anatomy.
    • Artifact reduction is achieved by combining CT/CBCT data with surface scans of plaster models.
    • A definitive dental splint is successfully fabricated using a 3D printer.

    Conclusions:

    • The presented 3D printing technique offers a precise and efficient method for creating orthognathic surgery splints.
    • This approach combines the benefits of traditional plaster models with advanced virtual 3D planning.
    • The technique enables the direct transformation of virtual surgical plans into physical dental splints.
