aceAI-assisted jaw and tooth segmentation and planning for maxillofacial fracture reconstruction
Source article: Artificial Intelligence in Occlusion-Oriented Digital Reconstruction of Maxillofacial Fractures: Current Applications and Translational Challenges
Abstract: Maxillofacial fractures require reconstruction of a functional craniofacial unit rather than isolated realignment of fractured bone. Stable occlusion, mandibular movement, temporomandibular joint position, facial contour, and fixation-device adaptation should be considered as interdependent treatment targets. Digital workflows incorporating CT or CBCT reconstruction, virtual surgical planning, CAD/CAM, 3-dimensional printing, patient-specific implants or plates, and navigation have improved visualization and sur…

This narrative review from August 2026 summarizes AI applications across occlusion-oriented digital reconstruction of maxillofacial fractures, where treatment must address stable occlusion, mandibular movement, temporomandibular joint position, facial contour, and fixation as interdependent targets. It evaluates tasks from CT/CBCT screening and segmentation to model repair, shape completion, planning assistance, and postoperative deviation analysis.
The review matters because it clarifies which AI tools are ready for supervised clinical support versus those that remain exploratory, helping avoid premature autonomous use in complex facial trauma. Uncertainty remains around generalizability, with authors calling for multicenter annotated datasets, external validation, uncertainty reporting, and auditable human-in-the-loop workflows tied to functional and patient-reported outcomes.
- Digital workflows incorporating CT or CBCT reconstruction, virtual surgical planning, CAD/CAM, 3-dimensional printing, patient-specific implants or plates, and navigation have improved visualization and surgical transfer.
- Review classified AI applications as near-term supervised clinical support, intermediate translational tools, exploratory research applications, or not ready for routine clinical use.
- A representative clinical workflow scenario is included to illustrate how these tasks can be integrated into surgeon-led planning without converting AI outputs into autonomous surgical decisions.
AI provides supervised decision support for fracture triage, preliminary jaw and tooth segmentation, planning preparation, and postoperative measurement in occlusion-oriented maxillofacial fracture reconstruction.
Labor-intensive segmentation and factors like comminution, bilateral injury, loss of anatomic references, and metal artifacts still restrict efficiency and reproducibility of digital reconstruction workflows.
The rundown
The review covers the full occlusion-oriented chain including image screening, craniofacial and dental segmentation, tooth numbering, model repair, 3-dimensional shape completion, planning assistance, intraoperative registration, and postoperative deviation analysis, evaluated by clinical task, evidence maturity, implementation risk, and translational feasibility.
Authors emphasize surgeon-led integration and propose outcome measures that link radiographic accuracy with occlusal contact, masticatory efficiency, temporomandibular function, patient-reported outcomes, and cost-effectiveness rather than autonomous surgical decisions.
Shape completion, automated reduction, fixation design, and real-time intraoperative feedback remain early translational and require stricter validation, with future work needing multicenter annotated datasets and external validation.
