Absolute augmentation of the mandible.

K Lekkas

    International Journal of Oral Surgery
    |June 1, 1977
    PubMed
    Summary

    A novel surgical technique minimizes bone resorption after mandibular augmentation. This new method involves splitting the mandible and inserting bone, allowing for a normal prosthesis and virtually eliminating resorption over two years.

    Area of Science:

    • Oral and Maxillofacial Surgery
    • Regenerative Medicine
    • Biomaterials Science

    Background:

    • Mandibular augmentation aims to increase jaw size but faces challenges with bone graft resorption.
    • Current techniques often result in significant loss of grafted bone volume over time.
    • This limits functional and aesthetic outcomes for patients requiring mandibular reconstruction.

    Purpose of the Study:

    • To introduce and evaluate a novel surgical technique for mandibular augmentation.
    • To address the issue of significant bone resorption associated with traditional methods.
    • To improve long-term stability and functional outcomes in mandibular reconstruction.

    Main Methods:

    • A new technique was developed involving splitting the resorbed mandible into cranial and caudal portions.
    • Bone graft material is placed between these two mandibular fragments, rather than subperiosteally.
    • The procedure spans from the left to the right third molar region.

    Main Results:

    • The novel technique demonstrated minimal bone resorption over a two-year follow-up period.
    • Resorption was practically nil in the evaluated cases.
    • Patients were able to wear a normal prosthesis, indicating functional restoration.

    Conclusions:

    • This innovative mandibular augmentation technique significantly reduces bone resorption.
    • The method offers improved stability and functional recovery for patients.
    • It represents a promising advancement beyond experimental stages in mandibular reconstruction.
