Orthodontic treatment--yes or no? A difficult decision in some cases. A contribution to the discussion

Reasons for orthodontic treatment are discussed on the basis of 1. evidence-based knowledge from the literature, 2. viewpoints based on clinical experience, 3. case presentations. Viewpoints regarding prophylactic aspects of orthodontic treatment in relation to oral health are critically evaluated. The clinically based experience that dentofacial esthetics is the main reason for most patients requesting orthodontic treatment is also well documented in the literature. Against this background, psychosocial aspects as an indication for orthodontic treatment deserve greater recognition.
