The Latest Progress On Robot Assisted Jaw-In-A-Day

Aim or purpose: Microvascularized bone tissue transplantation is an important milestone in reconstruction of jaws after resection of jaw tumors. It takes 6 to 18 months to restore the dentition even if the traditional free osteomyocutaneous flap transplantation immediately reconstructs the jaw. Dentition defects seriously affect the quality of life of patients and put a great psychological burden on edentulous patients. Materials and methods: With the advent of 4P/5P medicine era, surgery forwards higher requirements on predictability and personalization. Simultaneous reconstruction of jaw and dentition (jaw-in-a-day) is the state of art in complete jaw reconstruction at present, which can meet the above requirements. Jaw-in-a-day, supported by virtual surgery, CAD/CAM and robot, is the combination of jaw tumor resection, vascularized osteomyocutaneous free flap transplantation, dental implant placement and provisional denture restoration in one surgery. Results: The appearance and function of eight patients with tumor resection are reconstructed immediately in jaw-in-a-day, which reflects an “occlusion-driven reconstruction” notion. Conclusions: Jaw-in-a-day operation can be conducted as carefully planned. However, perioperative management and surgical process, and surgical skills and trouble-shooting need to be elucidated.
