Thepatient complain- edabout facialaesthetics and convexprofile, andhadboth lower first molars extracted about 2 years ago. There was agenitionof the right upper first premolar,deep bite and anterior crossbite. Clinicalexamination showed a Class I relationship forthe teeth and cephalometric measurementsshowed a Class IIskeletal tendency.The left upper first premolar was extracted for anterior crowding correction andoverbitecorrection. Thespace ofthe missing lower first molar was used for correction oflower crowd- ing.A two-step extraction technique was used to correct the patient's verticalplaneandprofile. It is concludedthat upper first premolar extraction is one of the options in the treatment of crowding. Unilateral extraction treatment can be performed to achieve an aesthetically pleasing and functionally stable occlusion.
