    Human teeth proved effective for ossicular reconstruction in tympanoplasty, offering satisfactory and long-lasting hearing improvement. This study highlights teeth as a promising prosthetic material for middle ear surgery.

    Area of Science:

    • Otolaryngology
    • Biomaterials Science
    • Regenerative Medicine

    Background:

    • Ossicular reconstruction is crucial for restoring hearing in patients with middle ear disease.
    • Autografts and allografts have limitations, creating a need for ideal prosthetic materials.
    • Human teeth offer a readily available and biocompatible option.

    Purpose of the Study:

    • To evaluate the efficacy and long-term outcomes of using human teeth for ossicular reconstruction.
    • To assess the graft take rate and hearing improvement following tympanoplasty with tooth prostheses.
    • To determine if human teeth meet the criteria for an ideal prosthetic material in otologic surgery.

    Main Methods:

    • Human teeth were utilized as prosthetic materials in 20 cases of tympanoplasty.

  • The study involved a follow-up period exceeding 2 years for all patients.
  • Outcomes were assessed based on graft take and audiological improvements.

    • Main Results:

    • Satisfactory graft take was observed in the majority of cases.
    • Significant and long-lasting hearing improvement was achieved.
    • The use of human teeth demonstrated favorable functional outcomes.

    Conclusions:

    • Human teeth are a viable and effective material for ossicular reconstruction.
    • The tooth's properties make it a suitable candidate for an ideal prosthesis in tympanoplasty.
    • This preliminary report supports further investigation into dental materials for otologic applications.
