Abstract: Objective: To review the therapeutic methods of the displaced mandibular impacted wisdom teeth. Methods: 8 cases of displaced teeth during the extraction of third molars from January 2014 to April 2019 were reviewed. Bimanual palpation and image examination were used to locate the displaced teeth. Relaxation incisions were made distally and medially of the extraction sockets under local anesthesia, then mucoperiosteal flaps were raised to retrieve the teeth. Results: 8 displaced teeth were successfully managed. 3 months later, the wound healed well and the post-operative recovery was uneventful. Conclusion: Through bimanual palpation and image examination, relaxation incisions at the distal and mesial sides of the extraction sockets were useful to retrieve the displaced teeth
