Orthodontic examinations (MEQ-3)
Matthew is an 11-year old boy whose chief complaint is his irregular teeth. His
parents observed that he has a very persistent habit of biting his lower lip.
Clinical examination finds that Matthew has exposed and proclined upper front
teeth and, incompetent lips. Cephalometric analysis reveals a marked discrepancy
between upper and lower jaws in sagittal plane, with an apparent indication of
both protrusion mavilla and retrusive mandible.

1. Proclined upper frontal teeth
