Distribution (relative frequency in %, maxilla and mandible=100%, respectively) of the anterior space situation (positive values=space excess (spacing), negative values=space deficiency (crowding), separately for males and females (males: n=235 in maxilla and n=237 in the mandible; females: n=256 in both jaws)
