Summary

A modified rib grafting technique effectively treated severe mandibular atrophy in eight patients. This approach showed satisfactory clinical results with minimal bone resorption over an eight-year follow-up period.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Severe mandibular atrophy presents significant challenges in reconstructive surgery.
  • Traditional grafting techniques may be limited by donor site morbidity and graft resorption.
  • The lower border rib grafting technique offers a potential solution for mandibular reconstruction.

Purpose of the Study:

  • To evaluate the efficacy and long-term outcomes of a modified lower border rib grafting technique for severe mandibular atrophy.
  • To assess the degree of graft resorption and clinical satisfaction following the surgical procedure.

Main Methods:

  • A cohort of eight patients with severe mandibular atrophy underwent reconstruction using a modified lower border rib grafting technique.

  • Patients were followed clinically for a period of two to eight years post-surgery.
  • Radiographic and clinical assessments were performed to evaluate graft integration and patient outcomes.

    • Main Results:

    • The modified lower border rib grafting technique yielded highly satisfactory clinical results in all eight patients.
    • Graft resorption was minimal, measuring less than 12% at the two-year follow-up.
    • Long-term follow-up (up to eight years) indicated sustained functional and aesthetic outcomes.

    Conclusions:

    • The modified lower rib grafting technique is a reliable and effective method for reconstructing severe mandibular atrophy.
    • This surgical approach demonstrates favorable long-term outcomes with predictable bone maintenance.
    • The technique offers a viable option for improving patient quality of life through mandibular restoration.
