Orthodontic treatment process, any force applied to the treated teeth to make them move will inevitably produce a force in the opposite direction at the same time, the size of the same force, and support this movement of the orthodontic dentition caused by the reaction force of the situation is called “support resistance”. The most common clinical situation is anterior protrusion of the upper teeth, and commonly known as the “rabbit teeth” orthodontic process, the doctor will repeatedly mention the problem of support resistance with the patient. Traditional braces are categorized into mild, moderate and severe braces in terms of strength. Only with correct support design and good support control, “the teeth that should move move, the teeth that shouldn’t move don’t move”, can we achieve high-quality orthodontic results. Implant support is a technology that has just emerged in recent years, which is implanted into the bone with micro-implant titanium nails, using the bone as the support, which can meet the demand for support in the process of orthodontic treatment, and has become a hot spot of basic research for orthodontic scholars both at home and abroad. At present, the implant sites commonly used in the oral cavity are mainly in the posterior region of the molar teeth, and the implant to be used for repairing the gap between the missing teeth can be used as the implant support, but also as a denture restoration base, which is both economical and convenient, and the posterior region of the molar teeth and the palate can be selected as the implant site when the teeth are intact or the gap between the teeth to be extracted needs to be closed. This new type of intraoral support can accomplish various types of orthodontic movement such as tooth tilting, turning distance, rotation, pressing in, elongation, etc. It is very effective for cases that need strong support, open gum smile, and need to depress the molars before restoration, and has a great potential for clinical application. The implant implantation surgery is easy to operate, comfortable for the patient, and does not require the patient’s active cooperation, and its biggest advantage is that the support is sufficiently prepared to completely Its biggest advantage is that the support preparation is sufficient, which can completely utilize the extraction gap and make the front teeth maximally retracted, so as to improve the orthodontic effect, which is called “absolute support” in orthodontics. The disadvantage is that it will add an extra cost to the patient, and there is a certain risk of falling off, but with the continuous improvement of surgical technology, the rate of falling off has been extremely low.
