Anterior crossbite is a common orthodontic challenge that can result from skeletal, dental, or functional discrepancies. Traditional treatment approaches, such as removable appliances or intermaxillary elastics, often rely on patient compliance and may cause undesirable effects like anchorage loss or extrusion of adjacent teeth. The use of lower mini-implants as skeletal anchorage provides a reliable and predictable solution for anterior crossbite correction by facilitating controlled tooth movement without compromising posterior occlusion.

Mini-implants placed in the lower alveolar bone serve as absolute anchorage, allowing precise retraction or proclination of mandibular incisors, depending on the underlying etiology of the crossbite. In cases where the crossbite results from lingual positioning of the lower incisors, mini-implants can be used to apply labial forces, promoting proper incisor alignment without reciprocal movement of posterior teeth. Additionally, mini-implant-supported mechanics help prevent undesirable mandibular rotation and excessive bite opening, ensuring a balanced and stable occlusion.

Successful correction of anterior crossbite using lower mini-implant anchorage requires careful diagnosis, accurate placement of the anchorage device, and controlled force application. Studies have shown that mini-implant-assisted mechanics lead to stable and long-lasting results, particularly when combined with retention strategies that maintain the achieved occlusal relationships. As skeletal anchorage continues to evolve, lower mini-implants remain an invaluable tool for orthodontists, offering a minimally invasive, efficient, and patient-friendly approach to anterior crossbite correction.
