Intercortical alveoloplasty involves removal of the interseptal bone to allow collapse of both labial and palatal cortical plates. This creates a smooth and uniform alveolar ridge contour, facilitating better denture accommodation or implant placement. Simply removing one cortical plate or preserving all plates does not provide the desired ridge shaping. The technique reduces prominent interdental bone while maintaining ridge height by allowing controlled cortical plate repositioning. This enhances prosthetic fit and esthetics in post-extraction or pre-prosthetic surgery.
