Malocclusion Rethought
From “Malocclusion” to a broader paradigm: Occlusal Dysmorphisms.
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.
