Abstract
OBJECTIVE: To evaluate the adaptive changes and the stability in tongue posture following rapid maxillary expansion (RME) in patients without any signs or symptoms of respiratory disturbances. MATERIALS AND METHODS: Growing subjects with maxillary constrictions and bilateral buccal crossbites were included in the treatment group (n = 20). A control group (n = 20) comprised subjects with normal dentoskeletal features. RME appliances were used in the treatment group, with an average active expansion of 15 +/- 2 days. Cephalometric radiographs were traced and digitized to evaluate static tongue posture before RME and 6.75 +/- 0.48 months after RME. Follow-up radiographic evaluations of 17 expansion cases were also performed after an average of 29.25 +/- 1.85 months. Independent and paired t-tests were conducted to evaluate changes in tongue posture within and between groups. RESULTS: Results revealed significant reductions of tongue-to-palate (P < .05) as well as hyoid bone-to-mandibular plane (P < .01) distances following RME. The new tongue posture was found to be stable during the follow-up period. CONCLUSIONS: A higher tongue posture can be obtained with RME in children with no reported respiratory disturbances.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
