"Malocclusion" (from Latin <i>malum</i> = bad) traditionally labels an improper “closure” of teeth. Yet modern clinical science shows that function cannot be reduced to mechanics alone. Electrophysiological findings (e.g., symmetry in motor-evoked potentials, jaw-jerk, and silent period) often reveal balanced trigeminal dynamics even in the presence of occlusal discrepancies. 


This challenges the conventional label “malocclusion” and supports a broader concept: <b>Occlusal Dysmorphisms</b>. Within a complex-systems view of mastication, neuromuscular coherence can coexist with occlusal asymmetries, urging interdisciplinary diagnostics that integrate occlusion with neurophysiology to achieve stable outcomes and reduce relapses.

Malocclusion Rethought

The term "Malocclusion," derived from the Latin malum ("bad"), was first introduced by Edward Angle to define an improper “closure” of teeth.[1] Yet, the notion of "bad closure" remains ambiguous in medical contexts.

A PubMed search for "Malocclusion" yields over 33,000 articles,[2] but without clear consensus on its definition. Smaglyuk et al. stress the importance of an interdisciplinary approach in diagnostics,[3] yet a query for "interdisciplinary diagnostics of malocclusions" returns only four articles,[4] underscoring a major gap in the literature. This suggests a paradigmatic shift may be underway, as described in Kuhn’s phase 4 model.

«Diagnosis, treatment strategies, and prevention of anomalies and dento-facial deformities should consider the organism as a whole, particularly in children whose structures are still developing.»

A clinical case illustrates this complexity: a patient presented with a unilateral posterior crossbite and anterior open bite. Literature suggests orthodontic appliances and sometimes orthognathic surgery are indicated.[5] Crossbite correction is equally important due to its functional link with open bite.[6] In this case, however, the patient refused treatment, claiming function was unaffected.

Electrophysiological testing revealed functional symmetry in the masticatory system despite occlusal discrepancies. Findings included:

  • Figure 1a: Malocclusion with open bite and right posterior crossbite.

  • Figure 1b: Motor-evoked potential symmetry in masseter muscles.

  • Figure 1c: Jaw reflex test confirming functional balance.

  • Figure 1d: Mechanical silent period indicating neuromuscular coherence.

These results challenge the reductionist view of malocclusion, showing that **neuromuscular balance may coexist with occlusal asymmetries**. Hence, diagnostic strategies must integrate occlusion with neurophysiology to avoid oversimplification.

Occlusal Dysmorphisms, not simply Malocclusion — an entirely different paradigm.
