Two treatment approaches for missing or peg-shaped maxillary lateral incisors: a case study on identical twins

Patients with missing or malformed maxillary lateral incisors can be successfully treated by either replacing or restoring the lateral incisor, or by positioning and reshaping the canine to simulate the lateral incisor. Identical twins were treated, one by restoring "peg laterals" to normal contours and the other by repositioning and recontouring the canines to simulate missing lateral incisors. Results of treatment would tend to indicate that considerations other than changes in facial esthetics should determine the treatment of choice.
