The assertion that malocclusion has no relation to TMD acknowledges the complex interplay of various factors involved in the development of temporomandibular disorders. While some theories suggest a potential link between malocclusion and TMD, research indicates that TMD can arise from multiple etiological factors such as trauma, stress, and muscle dysfunction, rather than being directly caused by malocclusion alone.

The reason this understanding is crucial in orthodontics is that treating malocclusion does not automatically alleviate TMD symptoms. Therefore, it's important for practitioners to evaluate a broad range of contributing factors beyond just dental alignment when diagnosing and planning treatment for TMD. This perspective reinforces the need for a comprehensive approach to patient care, where multiple aspects of a patient's condition are taken into consideration. Additionally, the varying responses and subjective experiences of patients with TMD further underline the complexity of the relationship between malocclusion and these disorders.
