Splinting and replantation after traumatic avulsion.

J C Kehoe

    Journal of the American Dental Association (1939)
    |February 1, 1986
    PubMed
    Summary

    Successful dental avulsion and replantation requires careful management of extraoral time, tooth transport, and root surface handling. Prompt endodontic treatment and appropriate splinting are crucial for optimal outcomes.

    Area of Science:

    • Dentistry
    • Endodontics
    • Oral Surgery

    Background:

    • Dental avulsion, or the complete displacement of a tooth from its socket, presents a significant clinical challenge.
    • Successful replantation depends heavily on timely and appropriate management of the avulsed tooth and its supporting structures.

    Purpose of the Study:

    • To outline a rational, evidence-based approach for managing dental avulsion and subsequent replantation in a dental office setting.
    • To emphasize critical factors influencing the prognosis of replanted teeth.

    Main Methods:

    • Review of established protocols for managing avulsed teeth, focusing on extraoral time, transport media, and root surface preservation.
    • Discussion of endodontic treatment timing based on root apex development (open vs. fully formed).
    • Consideration of alveolar process integrity, splinting techniques, and obturation materials.

    Main Results:

    • Minimizing extraoral time is paramount; longer durations significantly decrease prognosis.
    • Proper tooth transport (e.g., in the socket, milk) and gentle root surface management (avoiding handling or scraping) are vital.
    • Endodontic treatment timing varies: revitalization assessment for open apices, pulp extirpation within 7-14 days for fully formed apices.
    • Alveolar fractures may necessitate modified splinting; calcium hydroxide is used for obturation before permanent filling.

    Conclusions:

    • A systematic approach considering all factors from avulsion to final restoration is essential for successful dental replantation.
    • Clinical experience and judgment are key in selecting appropriate splinting methods and durations.
    • Adherence to best practices maximizes the chances of preserving tooth vitality and function.
