Patients tolerated the various insertion procedures equally well. However, there were differences with regard to the injection technique: The patients favored an injection immediately next to the mini-implant insertion area.

The patients tolerated the two removal procedures equally well. As the noise associated with the handpiece increased discomfort, manual removal of the mini-implants is preferable. As regards the injection technique, our results show that local anesthesia during removal does not provide a benefit. The most pain was caused by the injection, not by removal of the mini-implants.
