Reconstruction of the temporomandibular joint after surgical ablation of a multiply recurrent ameloblastoma: a case report.
Bibliographic record
Abstract
Reconstruction of large mandibular defects, whether involving the temporomandibular joint (TMJ) or not, has historically been achieved with autogenous grafts, such as free costochondral grafts and vascularized bone grafts. Ensuring intact, functioning microcirculation is critical for graft survival in the face of postoperative radiation therapy secondary to malignant tumour ablation. However, in the case of benign tumours, such as ameloblastomas, postoperative radiation therapy is not required, thus increasing the options for reconstruction. Alloplastic components coupled with nonvascularized bone grafts have been used successfully to restore mandibular form, function and esthetics after extensive mandibular resection. In this article, we describe a case of a multiply recurrent ameloblastoma treated by left hemimandibulectomy and immediate reconstruction with a custom-fabricated alloplastic system in combination with an anterior iliac crest bone graft. The result was a high degree of mandibular function and facial cosmesis, minimal donor-site morbidity, and nearly immediate return to function.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
