Recently, orthodontic anchor mini-screws have been widely used in orthodontic treatment. Fractures of the implants, soft-tissue infections, and injuries of the roots of adjacent teeth are reported as complications of implantation. We report a case of fracture of an orthodontic anchor mini-screw during implantation in the palate. <br>An orthodontic anchor mini-screw was implanted for the patient at a dental clinic. During the procedure, the mini-screw fractured and remained under the mucosa, so she was referred to our hospital to remove the remaining mini-screw. The fractured mini-screw was impacted under the palatal mucosa. Computed tomography revealed a fractured screw in the midline of the palate. We removed the screw under general anesthesia using an ultrasonic bone cutting device. <br>Anchor screw fracture is considered to be caused by excessive torque at the time of implantation. To avoid this problem, it is essential to form the guide hole in advance and then to implant the anchor screw using a torque screwdriver.
