The importance of the facial profile in orthodontic diagnosis and treatment planning: a patient report.

Orthodontic treatment to improve not only tooth alignment but also facial esthetics is a given in modern society.

Maxillary expansion was followed by face mask therapy and orthodontic treatment, which significantly improved the soft tissue profile by projecting the upper lip.
