The term “geodesic” generally refers to a reverse jaw, and the ways to improve children’s reverse jaw include anterior teeth reverse jaw treatment or posterior teeth reverse jaw treatment, which needs to be customized according to the specific situation. Children with posterior antimandibularity can be treated during the period of milk teeth by using maxillary dentition cushion tongue and groove appliances, etc.; during the period of replacement teeth by using functional appliances, fixed appliances or removable appliances, etc.; and during the period of permanent teeth by using orthodontics-orthognathic combination treatment or masking orthodontic treatment, etc. Children with dental posterior antimandibulars can be treated with maxillary expanders, removable appliances, interactive traction, or subtractive designs, while patients with bony posterior antimandibulars require surgical treatment to assist with rapid palatal development of the upper jaw and compensatory orthodontic treatment with interactive traction.
