RESUMEN
The soft tissues covering the face play an important role in facial aesthetics, speech and function. Detailed soft tissue analysis is an important component of comprehensive diagnosis and treatment planning. A balance between the dental and the perioral muscles must be achieved to attain stability of the treatment outcome. The aim of the study was to compare soft tissue facial profile between skeletal class I and class II subjects and to find out difference in soft tissues adaptation on the basis of gender. Non probability sampling technique was used. Eighty patients were selected with age ranging 14 to 18 years. For each patient a lateral cephalogram was taken and cephalometric analysis was performed. The study showed that patients with class II skeletal pattern have more convex profile. Both upper and lower lips are more protrusive than the normal and lower lip length in males is slightly greater than the normal
