Splinting and replantation after traumatic avulsion

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.
