    Area of Science:

    • Biomaterials Science
    • Oral and Maxillofacial Surgery
    • Histotechnology

    Background:

    • Studying bone regeneration around dental implants is crucial for improving prosthodontic outcomes.
    • Current methods for hard tissue preparation can be time-consuming and may lead to artifact.
    • The interaction between carbon implants and bone tissue requires high-quality sectioning for accurate analysis.

    Purpose of the Study:

    • To develop and validate a new embedding and sectioning procedure for hard tissues.
    • To facilitate the study of bone regeneration adjacent to carbon implants in dental applications.
    • To improve the efficiency of hard tissue sample preparation for microscopic examination.

    Main Methods:

    • Hard tissues from nonhuman primate maxillas and mandibles with carbon implants were fixed and dehydrated.
    • Tissues were embedded in a modified Spurr's low-viscosity medium.
    • Sectioning was performed using a low-speed saw to achieve 50-100 micron thin sections.

    Main Results:

    • High-quality, undistorted tissue sections were obtained.
    • The procedure eliminated the need for decalcification, saving experimental time.
    • Carbon implants remained intact without fragmentation during the sectioning process.

    Conclusions:

    • The developed procedure offers an efficient and effective method for preparing hard tissues for microscopic analysis.
    • This technique is particularly beneficial for studying bone regeneration around implants in dental and maxillofacial research.
    • The high-quality sections enable detailed examination of tissue-implant interfaces.
