Summary Objectives: The aim of this study was to characterize facial and jaw morphology of children with Class III malocclusion in early mixed dentition. Methods: This study was conducted on 7- to 8-year-old Caucasian children, 48 children with Class III malocclusion and 91 children with normal occlusion. Surface images of faces and study casts were obtained using laser scanning.Two average facial templates were constructed for the males and females in the control group. The facial images were superimposed on the corresponding average templates. Facial parameters, palatal volumes, and gingival surface areas were measured and group differences were quantified.The analysis of variance was used for statistical evaluation of the measured parameters. Results: The results revealed shorter lower face height (P
