Normal 0 false false false EN-US X-NONE AR-SA The study's purpose was to estimate the value of symphysis morphology as a standard for anticipating direction of mandibular growth. 160 patients were sampled (80 f/80 m) and formed 8 groups based on gender,age and growth spurt. Mandibular growth direction was evaluated via 6 cephalometric indices: Mandibular Arc angeles, Lower facial Height, Facial Axis , Facial Angle ,Facial Taper and Mandibular Plane. Height, depth and their ratio and angle of symphisis were measured. The highest relation found among 13-16 yrs females as well as +20yrs males. Symphysis angle showed the highest relation in male patients. In 9-12 yrs females and 10-14 male patients in which anticipating the growth is highly needed, the relationship between symphysis morphology and mandibular groth indices was not significant.
