Abstract

The maxillary six anterior teeth play important roles in esthetics and oral function. Treatments for missing maxillary lateral incisors either by space closure or space preservation need multiple clinical considerations. This case report presents an orthodontic treatment of a 33-year-old female patient who had a convex profile with lip incompetence, missing lower molars and poor prognosis of bilateral maxillary lateral incisors. The atypical extraction in treatment plan consisted of removing lateral incisors instead of premolars to retract the anterior teeth. The improvement of facial profile and lip posture was achieved and the anterior teeth esthetics was further rehabilitated with prosthesis. After 28-month of treatment duration, the patient was satisfied with treatment results.
