Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Digital Dentistry

Background:

  • Computer-assisted procedures are integral to modern mandibular reconstruction, particularly for complex defects from tumor surgery.
  • Virtual surgical planning (VSP) and additive manufacturing (AM) are key components of these digital workflows.
  • CAD/CAM tools, including surgical guides and patient-specific implants (PSIs), facilitate the transition from virtual planning to surgical execution.

Purpose of the Study:

  • To review the role and benefits of computer-assisted procedures in mandibular reconstruction.
  • To highlight the advantages of VSP, AM, and PSIs in complex cases.
  • To discuss current limitations and future potential of digital workflows in this field.

Main Methods:

  • Review of current literature and clinical practices in computer-assisted mandibular reconstruction.
  • Analysis of the application of VSP, AM, CAD/CAM tools, and PSIs.
  • Discussion of accuracy, efficiency, patient outcomes, and limitations.

Main Results:

  • Computer-assisted approaches, including VSP and AM, are effective for complex mandibular defects.
  • Patient-specific implants (PSIs) are valuable for osteosynthesis and bone element positioning.
  • These methods offer potential for improved accuracy, efficiency, and patient outcomes.

Conclusions:

  • Computer-assisted procedures significantly benefit complex mandibular reconstruction, especially after tumor resection.
  • While cost and availability are limitations, future advancements like automation and AR hold promise.
  • Digital workflows are transforming the field, enhancing surgical precision and patient results.
