“Understanding the role of facial profile analysis in orthodontics”

Facial profile is examined by viewing the patient from the side.

• Facial profie helps in diagnosing gross deviations in the maxillomandibular relationship.
• The profie is assessed by two reference lines and three landmarks:
• Three landmarks are used which are soft tissue nasion, nasion and sof tissue pogonion.

“Importance of studying facial profile metrics for better treatment outcomes”

• Two reference lines are
  • First line is dropped from soft tissue nasion to subnasale
  • Second line is dropped from subnasale to sof tissue pogonion
• So, based on the relationship of two lines and the three landmarks the facial profile exists as:
  • Straight profile: Two lines form a nearly straight line.
  • Convex profile: Two lines form an angle with the concavity facing the tissue.
  • Concave profie: Two reference lines form an angle with the convexity towards the tissue.
