Abstract

fetched live from OpenAlex

Objetivos: Describir y comparar los posibles efectos periodontales indeseados como consecuencia de la expansión maxilar en pacientes adultos usando expansores no quirúrgicos con anclaje esquelético y expansión maxilar asistida quirúrgicamente. Materiales y métodos: Se realizó una búsqueda exhaustiva en las bases de datos electrónicas PubMed, Medline, Cochrane y LILACS. Además, se realizaron búsquedas manuales en revistas y literatura gris sin ninguna restricción. Después del proceso de selección y extracción; el riesgo de sesgo se evaluó mediante la herramienta ROB-1 Cochrane y la escala Newcastle-Ottawa (NOS) para ensayos aleatorios y estudios de cohortes, respectivamente. Resultados: De 621 estudios recuperados de las búsquedas, seis finalmente se incluyeron en esta revisión. Uno presentó bajo riesgo de sesgo, mientras que cinco fueron excelentes en cuanto a selección, comparabilidad y resultados. Los resultados mostraron que la expansión maxilar en adultos utilizando expansores con anclaje en tejido esquelético o anclaje dentario-esquelético bicortical produce efectos periodontales menos dañinos, tales como: flexión alveolar con un rango promedio de 0.92º a 2.32º, en comparación a la expansión maxilar asistida quirúrgicamente con anclaje dentario de 6,4º; inclinación dentaria con un rango promedio de 0,07º a 2,4º, en comparación con la expansión maxilar quirúrgicamente asistida con anclaje dentario con un rango de 2,01º a 5,56º. Conclusiones: Aunque limitada, la evidencia actual parece mostrar que los la expansión en adultos no quirúrgica con anclaje esquelético o dentario esquelético bicortical producen menos efectos periodontales indeseables.

Not 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.
