Growth changes in the soft tissue facial profile.

摘要: Longitudinal growth changes in the soft tissue profile of 40 caucasians between ages 7 and 18 were studied. The sample consisted 17 males 23 females who had Class I dentitions balanced faces at age years. None subjects received any orthodontic treatment. Cephalometric radiographs available, as a rule, on yearly basis. Soft thickness, measured nose, upper lip, lower lip chin, well length all increased by varying amounts over period study. Females acquired more percentage their adult size (at 18) than variables except angle inclination skeletal chin which males. largest increase relative was noted nose measurements. In males, not attained even 18. Upper growth, other hand, both complete 15th year. difference male female clinically significant; average aggregate lips combined 6.9 millimeters compared to 2.65 females. total gain thickness laberale superius four times much continued change pogonion large, an 2.4 1.5 major contribution anterior translatory, contributed largely from pterygomaxillary plane.
