Abstract
The overall prevalence of peg-shaped maxillary permanent lateral incisors was 1.8%. The occurrence rates were higher in Mongoloid (3.1%) than in black (1.5%) and white (1.3%) patients. The presence of peg lateral incisors was also a complicated esthetic issue for orthodontist. This case is a skeletal Class III malocclusion 20-years-old male. His problems were mild maxillary skeletal retrognathism combined with mandibular prognathism, anterior crossbite, peg lateral incisors, and upper arch crowding. Treatment involved extraction of two maxillary lateral incisors. Maxillary canine substituted for lateral incisors. Before orthognathic surgery, the extraction spaces were closed for crowding relief of upper arch and dental decompensate was also achieved. Finally, the orthognathic surgery was performed to correct the problem of severe skeletal Class III. After 30 months of treatment, the facial profile was improved and ideal occlusal relationship was achieved.
