This study introduces a simple, inexpensive method for creating custom titanium bone grafting trays for mandibular reconstruction after surgery. The technique offers excellent facial contour and functional results, overcoming limitations of existing methods.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomaterials Engineering
  • Reconstructive Surgery

Background:

  • Mandibular reconstruction after ablative surgery presents challenges with existing preformed or computer-assisted trays.
  • Preformed trays struggle with precise facial contour, jaw relationship, and condylar positioning.
  • Computer-assisted modeling systems are effective but prohibitively expensive.

Purpose of the Study:

  • To present a simple and cost-effective method for fabricating custom-made titanium bone grafting trays.
  • To provide an alternative to expensive or imprecise reconstruction methods.
  • To achieve excellent facial contour and functional outcomes in mandibular reconstruction.

Main Methods:

  • Clinical measurements of the patient's mandible are taken.

Related Experiment Videos

  • A mandibular replica is constructed using these measurements.
  • The replica is modified to create an ideal shape for the edentulous segment, and the tray is fabricated via casting or swaging.

    • Main Results:

    • Twenty-one custom-made titanium bone grafting trays were successfully fitted in patients.
    • The method demonstrated encouraging results in achieving desired outcomes.
    • The technique proved effective in addressing limitations of conventional methods.

    Conclusions:

    • The presented method offers a simple and inexpensive approach to fabricating custom titanium bone grafting trays.
    • This technique facilitates excellent facial contour and functional reconstruction after mandibulectomy.
    • It provides a viable and cost-effective solution for complex reconstructive challenges.
