Atrophy of edentulous maxillary alveolar ridge

Last edited: 4/15/2026

Overview

Severe atrophy of the edentulous maxillary alveolar ridge limits implant placement options, necessitating advanced reconstructive techniques such as calvarial bone grafting to facilitate prosthetic rehabilitation 1.

Diagnosis

  • Clinical assessment reveals significant bone loss in the maxillary arch, often classified using the Cawood and Howell classification system 1.
  • Radiographic imaging (CT, CBCT) essential for assessing bone height and quality 1.
  • Sinus floor evaluation via imaging to plan for potential sinus lift procedures 1.

    • Management

  • Calvarial bone grafting: Utilized for severe cases to augment bone volume, enabling implant placement 1.
  • Sinus lifts: Often performed concurrently with bone grafting to increase bone height in the posterior maxilla 1.
  • Sedation: Preferred over general anesthesia for harvesting calvarial bone to minimize complications and enhance patient comfort 1.

    • Special Populations

  • No specific recommendations provided for pregnancy, pediatrics, or elderly patients in the given abstracts 1.

    • Key Recommendations

  • Consider calvarial bone grafting for severe maxillary atrophy to facilitate implant placement, particularly when intraoral bone is insufficient 1 (Evidence: Moderate).
  • Perform sinus lifts in conjunction with bone grafting to enhance bone volume in the maxillary arch 1 (Evidence: Moderate).
  • Opt for sedation over general anesthesia during calvarial bone harvesting to reduce complications and improve patient recovery 1 (Evidence: Expert opinion).
