Objective: The purpose of this study is to compare the craniofacial growth of individuals with skeletal class III and class I structure at different stages of growth periods. Methods: The study includes 266 untreated individuals with class I and class III malocclusion admitted for orthodontic treatment. The individuals were divided according to their genders— male and female—and growth periods based on the hand–wrist films. The differences between the growth periods and sex groups of class I and class III individuals were statistically evaluated. Results: In the study, there was no difference between class I and class III in terms of anterior and posterior cranial base length. The cranial base angle was shown to be lower in class III individuals than in class I individuals. Effective maxillary length (Co-A) is significantly lower in class III patients than in class I individuals. Mandibular growth dimensions of the class III and class I groups are similar in the early period however, differences between the two groups increase in later periods. Craniofacial and mandibular sizes were larger in class I and class III males than females. We found that protrusion of the maxillary incisor and retrusion of the mandibular incisor become increas-ingly evident as development progresses. Conclusion: In class III and class I individuals, the amount of maxillary and mandibular growth is similar in the early stages of development, whereas in class III individuals the skeletal discrepancy is intensified in the later stages of development.
