: One of the main aspects of orthodontic treatments is hard and soft tissue changes and their effects on patients appearance.Fixed orthodontic treatment with extraction of upper first premolars to camulfalge of ci II malocclusion is very common,however there is not sufficient studies about lip and incisors changes after this procedure. For evaluating of vertical changes of upper, lip and incisors following retraction of upper incisors, fifteen adult Iranian patients aged 15 to 24 years who sought treatment for their CI II DI malocclusion were treated. Standard edgewise technique(0.018") following extraction of four first premolars were used.A cephaiometric study was undertaken to determine the vertical change in upper incisors and upper lip. For this evaluation, thirty linear and angular measurements were utilized.Results show that: 1- The upper incisors were intruded (X=0.83mm).2- The upper lip length was increased(X~1.2mm).3- The occlusal plane, rotated upward (Anteinclination).4- The palatal plane rotated downward and backward (Retroinclination).This study shows that the standard edgwise appliance has the capacity of reduction of incisor protrusion significantly without extruding them.
