Secondary Alveolar Bone Grafting: An Outcome Analysis
Bibliographic record
Abstract
OBJECTIVE: To review the outcome of secondary alveolar bone grafting in unilateral and bilateral cleft lip and palate. DESIGN: A surgeon's experience, by retrospective chart review, of 70 consecutive patients at a tertiary care centre. OUTCOME MEASURE: Periapical radiographs were taken at least six months after secondary alveolar bone grafting. The Enemark grading system was used to stratify graft-take. RESULTS: In unilateral clefts, 33% were level 1, 36% were level 2, 20% were level 3 and 11% were level 4. In bilateral clefts, 29% were level 1, 50% were level 2, 14% were level 3 and 7% were level 4. There was no statistically significant difference between the level of take and the type of cleft. Complications encountered were infection (n=3), fistula (n=3), pain (n=4) and bone graft exposure that led to failure (n=2). Two patients required reoperation for bone grafting. CONCLUSIONS: The iliac crest is a good donor site with excellent results and minimal morbidity.

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.
