Abstract

Background/purpose

Jaw-in-a-Day (JIAD) integrates oncologic resection, fibula free-flap reconstruction, and immediate implant-supported prosthetic rehabilitation in a single operation. This study aimed to use the dynamic navigation-assisted implant placement for the JIAD mandibular reconstruction.

Materials and methods

We reported a JIAD case employing a hybrid workflow that combined conventional static guides with intraoperative dynamic navigation to enhance implant placement accuracy. Comprehensive computer-aided surgical simulation and virtual surgical planning were performed using Mimics and 3Shape software, followed by the navigation-assisted implant placement during fibula preparation.

Results

The postoperative course was uneventful, and the patient was discharged three weeks after surgery. The 2-month postoperative cone-beam computed tomography demonstrated that angular deviation, platform depth deviation, and apical depth deviation were all within reported ranges for dynamic navigation–guided implant placement.

Conclusion

Incorporation of dynamic navigation into the JIAD workflow provides intraoperative adaptability and improve implant accuracy and reconstructive reliability in a complex mandibular reconstruction.
