This study evaluated the efficacy of rapid molar intruder (RMI) in treating anterior open bite in the mixed dentition. The study sample consisted of 40 patients who had a skeletal anterior open bite. The sample was allocated randomly into two groups: the RMI group and the control group. The skeletal, dentoalveolar and soft tissue changes occurring after treatment were assessed by using lateral cephalometric images.
