Dynamic navigation-assisted implant placement for the jaw-in-a-day mandibular reconstruction.

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.
