SARPE combines oral surgery and orthodontics to widen a fused adult palate-essential when skeletal expansion (not just dental tipping) is needed Adults with transverse maxillary deficiency (e.g., crossbites, crowding, breathing issues) can't use regular expanders. SARPE unlocks structural resistance, enabling predictable skeletal change and improved occlusion.After placing a palatal expander, surgeons perform osteotomies (cuts in the palate and buttress areas) and then gradually activate expansion, promoting new bone formation and stability.Provides reliable skeletal expansion, reduces dental side-effects, improves nasal airflow, and shows good long-term stability when correctly executed Understanding SARPE is crucial for informed decisions: it offers effective skeletal correction options beyond traditional orthodontics.
