The term symptomatic classification in orthodontics primarily refers to categorizing malocclusions based on their functional implications rather than just anatomical or developmental causes. Functional malocclusions arise due to abnormal muscle function or habits that affect occlusion, distinguishing them from purely skeletal or dental issues. This classification helps in identifying the underlying functional disturbances impacting the occlusion, guiding appropriate therapeutic interventions focused on muscle and functional correction. Thus, it emphasizes the symptoms caused by altered function rather than structural anomalies.
