This study explores composite bone grafts for severe mandibular atrophy, showing promising functional and psychological improvements. Combined with osseointegrated implants, this technique offers a superior alternative to traditional grafting methods.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Severely atrophic mandibles pose significant reconstructive challenges.
  • Traditional intraoral grafting techniques can lead to resorption and require secondary procedures.
  • Patient acceptance and functional outcomes are critical considerations in mandibular reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of a composite cadaver-autogenous bone graft for treating severely atrophic mandibles.
  • To assess the benefits of combining this technique with osseointegrated implants.
  • To compare outcomes with previous intraoral grafting methods.

Main Methods:

  • A composite graft technique using cadaver and autogenous bone was applied to six patients.

  • Osseointegrated implants were used concomitantly with the bone graft.
  • Follow-up assessments focused on functional, aesthetic, and psychological outcomes.
  • Main Results:

    • The composite graft technique, especially with osseointegrated implants, showed encouraging early results.
    • This method helps avoid severe resorption associated with intraoral superior border grafting.
    • Patients experienced improved function, aesthetics, and psychological well-being, with easier prosthesis wear.

    Conclusions:

    • Composite cadaver-autogenous bone grafting is a viable and effective technique for severely atrophic mandibles.
    • Concomitant use of osseointegrated implants maximizes the benefits of this reconstructive approach.
    • The procedure offers functional, aesthetic, and psychological advantages over traditional methods, leading to higher patient satisfaction.
