Controlling anchorage is one of the most important aspects of orthodontic treatment. Many traditional treatment protocols have incorporated both extraoral (headgear) and intraoral (elastics, TPA, etc,) approaches to maintain anchorage. Unfortunately, patient compliance is considered the "Achilles' heel" of facilitating tooth movement. In an effort to maximize anchorage while reducing patient dependence, microimplant has become a revolution in orthodontic anchorage preparation. Small diameter microimplant can increase the efficiency of treatment procedure when compared to the conventional orthodontic treatment.
Already, it has passed more than 2 decades since I applied microimplant in orthodontic treatment. The appearance of microimplant has brought about great changes in treatment planning, mechanics and treatment results. Many cases, difficult or even impossible with conventional mechanics, could be solved by use of microimplant. However, when microimplant is used, side effects such as inflammation, root damage, and fracture of microimplant still exist. Despite a few side effects, orthodontic microimplants are already a common tool to control anchorage without the need of patient compliance used in routine orthodontic practice.
In this presentation, I would like to exchange my knowledge and experience in orthodontics with using microimplants, including what has been changed during the last 20 years what has to be changed after using microimplant.
