The malocclusion prevalence rate is a large problem in Indonesia, and malocclusion should be treated at the appropriate age. During puberty, the growth rate increases, which can be used to correct malocclusion. Knowledge of the growth of the skull and jaw, especially that of the maxilla and mandible, becomes very important to design a proper treatment plan. The aim of this study was to determine the average lengths of the maxilla and mandible in 10-16-year-old boys and girls. This study used a descriptive cross-sectional design. The subjects were 211 cephalometric radiograms of 10-16-year-old children. The highest growth rate of the maxilla occurred at the age of 14-15 years in boys. The highest growth rates of the maxilla and mandible in girls and the highest growth rate of the mandible in boys occurred at the age of 13-14 years. The differences in the average lengths of the maxilla and mandible were not significant in boys and girls 10-13 years old but were significant in those >13-16 years old. There were significant differences in the maxillary and mandibular lengths between boys and girls 10-13 years old and those >13-16 years old.
