Upper alveolar protrusion is generally divided into two cases: 1, there is simple alveolar protrusion, if the alveolar bone protrudes and the base bone does not protrude, it can be solved by simple orthodontic treatment, and it can be corrected by extracting the teeth.2, if the upper alveolar protrusion is accompanied by the anterior protrusion of the whole maxillary bone, the effect of the simple orthodontic treatment may not be very good, and it is necessary to cooperate with the surgical treatment, that is, the combination of orthodontics and orthoprosthetics, and it can bring the The combination of orthodontic and orthognathic treatment can set back the whole maxillary base bone, which can achieve a more ideal orthodontic treatment of alveolar protrusion. Therefore, for each patient’s different situation, it is necessary to do specific clinical examination such as CT, to make a treatment plan according to the bone situation, and decide whether it is purely orthodontic treatment or combined treatment through surgery. If the upper alveolar protrusion is purely orthodontic treatment, it may need to be combined with implant nailing to move the upper front teeth backward for more definitive results.
