IMPORTANCE OF CLINICAL PHOTOGRAPHY
• Photometric analysis serves as a powerful method to address orthodontic malocclusion, establish treatment planning, evaluate surgical results and orthodontic outcome, and also study the facial growth.
• Use of photograph as a diagnostic aid was also established by many workers when they studied the impact of buccal corridor, lip line, or smile arc on facial attractiveness.
• Especially in the field of orthognathic surgery, where surgery can change the appearance of a face, 3D assessment is becoming very essential. Digital photography not only allows the clinician to plan the surgical procedures, but also aids in predicting the outcome.
