Prevention of undesirable tooth movement in both arches is now possible through the use of orthodontic mini-implants. This relatively new treatment concept has expanded the envelope of orthodontic treatment, offering an alternative to orthognathic surgery (particularly in the vertical dimension) and allowing asymmetric tooth movement in three planes of space. This textbook describes precise conditions and techniques for clinical application of orthodontic mini-implants. The first half presents biologic principles, design, and function of mini-implants, and the second half addresses surgical procedures for placement and the mechanotherapy specific to various types of predictable tooth movement. Recommended for all orthodontists, periodontists, oral surgeons, and students who have been seeking better treatment results.
