This study introduces a novel virtual reality planning method for mandibular distraction osteogenesis, crucial for complex facial deformities. This approach enhances predictability and reproducibility in treating pediatric mandibular deformities.

Area of Science:

  • Craniofacial surgery
  • Biomedical engineering
  • Orthodontics

Background:

  • Distraction osteogenesis is used for mandibular deformities, but planning three-dimensional mandibular distraction is complex.
  • Predictable outcomes in orthognathic surgery require careful presurgical planning, yet few methods exist for mandibular distraction planning.

Purpose of the Study:

  • To develop and present a novel method for planning mandibular distraction osteogenesis using three-dimensional modeling and virtual reality simulation.
  • To improve the predictability and reproducibility of surgical outcomes for complex mandibular deformities.

Main Methods:

  • Acquisition of a three-dimensional computerized scan of the facial skeleton.
  • Creation of a three-dimensional wire-mesh model and virtual distractor using animation software.

Related Experiment Videos

  • Simulation of osteotomies and the distraction process in virtual reality, followed by calculation of distractor sequencing.

    • Main Results:

    • The planning process was applied to seven pediatric patients (age 4-10) with unilateral or bilateral mandibular deformities.
    • The virtual reality planning method yielded predictable and reproducible results in all treated patients.

    Conclusions:

    • Virtual reality simulation using three-dimensional modeling offers a viable and effective method for planning complex mandibular distraction osteogenesis.
    • This advanced planning technique enhances surgical precision and patient outcomes for pediatric craniofacial reconstructions.
