    Autogenous bone grafts from the iliac crest and ribs effectively repaired partly resected mandibles in 23 patients. Solid block grafts yielded good jaw mobility and contours with minimal resorption, demonstrating successful mandibular reconstruction.

    Area of Science:

    • Oral and Maxillofacial Surgery
    • Reconstructive Surgery
    • Orthognathic Surgery

    Background:

    • Mandibular defects often require complex reconstruction.
    • Autogenous bone grafting is a common method for mandibular repair.
    • Evaluating graft success and long-term outcomes is crucial.

    Purpose of the Study:

    • To assess the efficacy of autogenous bone grafts (iliac crest and ribs) in reconstructing partly resected mandibles.
    • To evaluate graft healing, patient outcomes, and graft resorption.
    • To compare solid block grafts with other graft types.

    Main Methods:

    • Retrospective analysis of 23 patients undergoing mandibular reconstruction with iliac crest and rib bone grafts.
    • Graft fixation using plate osteosynthesis without intermaxillary fixation (IMF).

  • Follow-up duration ranged from 6 months to 11 years, including clinical and radiographic assessments.

    • Main Results:

    • Successful graft healing occurred in 21 out of 23 patients.
    • Good jaw mobility and satisfactory mandibular contours were achieved in most patients.
    • Radiographic evaluation showed slight to moderate graft resorption, even in cases with prosthesis loading.

    Conclusions:

    • Autogenous bone grafts, including solid block types, are effective for mandibular reconstruction.
    • Plate osteosynthesis without IMF can be a viable fixation method.
    • Satisfactory functional and aesthetic outcomes can be achieved with long-term graft stability.
