Deep bite, characterized by excessive vertical overlap of the anterior teeth, is a common orthodontic challenge that can lead to functional and esthetic concerns. Traditional treatment methods, such as intrusion arches, have been widely used to correct deep bite by applying intrusive forces to the anterior teeth. These arches, often fabricated with stainless steel or nickel-titanium wires, work by applying light, continuous forces to intrude the incisors, thereby reducing the severity of the deep bite. While effective, intrusion arches can sometimes result in unwanted side effects, such as excessive flaring of the incisors or anchorage loss in the posterior region, which may compromise overall treatment outcomes

Temporary Anchorage Devices (TADs), have revolutionized deep bite correction by providing absolute anchorage for precise anterior intrusion. Unlike intrusion arches, which rely on reciprocal forces that may lead to unwanted molar extrusion, mini-implants allow for direct intrusion of the anterior teeth without affecting posterior occlusion. By placing mini-implants in strategic locations, such as the interradicular space or the palate, orthodontists can apply controlled forces to intrude the incisors efficiently while maintaining posterior stability. This method not only ensures greater control over tooth movement but also reduces treatment time and minimizes the risk of relapse.

Studies comparing intrusion arches and mini-implant systems have shown that while both methods are effective, mini-implants offer superior control over tooth movement with fewer unwanted side effects. Additionally, TADs eliminate the need for patient compliance with auxiliary appliances, making them a more predictable option for deep bite correction. The integration of digital treatment planning and 3D imaging has further enhanced the accuracy of mini-implant placement, leading to improved outcomes. As orthodontic techniques continue to evolve, the use of mini-implant systems is becoming increasingly favored for deep bite correction, offering patients a highly efficient and stable treatment solution.
