From "bad bite" to a broader paradigm: Occlusal Dysmorphisms
</div>


<div class="landing-content">
The term "Malocclusion," derived from the Latin ''malum'' ("bad"), was first introduced by Edward Angle to define an improper “closure” of teeth.<ref>Attributed to [[:wpen:Edward Angle|Edward Angle]], the father of modern orthodontics.</ref> Yet, the notion of "bad closure" remains ambiguous in medical contexts.
'''In brief:''' many so-called "malocclusions" show functional symmetry at neurophysiological tests (MEP, jaw-jerk).
 
Purely occlusal targets risk ''relapse'' if neuromuscular factors are ignored.  
A PubMed search for "Malocclusion" yields over 33,000 articles,<ref>Pubmed, ''[https://www.ncbi.nlm.nih.gov/pubmed/?term=%22malocclusion%22 Malocclusion]''</ref> but without clear consensus on its definition. Smaglyuk et al. stress the importance of an interdisciplinary approach in diagnostics,<ref>{{cita libro
An interdisciplinary model improves long-term stability.

}} 72(5 cz 1):918-922.</ref> yet a query for "interdisciplinary diagnostics of malocclusions" returns only four articles,<ref>Pubmed, ''[https://www.ncbi.nlm.nih.gov/pubmed/?term=interdisciplinary+diagnostics+of+malocclusions Interdisciplinary diagnostics of malocclusions]''</ref> underscoring a major gap in the literature. This suggests a paradigmatic shift may be underway, as described in Kuhn’s phase 4 model.

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.<ref>{{cita libro

=== Why this matters ===
Electrophysiological testing revealed functional symmetry in the masticatory system despite occlusal discrepancies. Findings included:
* Electrophysiology can reveal balanced trigeminal dynamics even with occlusal issues.
<gallery mode="slideshow">
* A mechanistic-only view may miss neural drivers of orofacial dysfunction.
File:Occlusal Centric view in open and cross bite patient.jpg|'''Figure 1a:''' Malocclusion with open bite and right posterior crossbite.
* Integrating occlusion + neurophysiology reduces relapses and improves outcomes.
File:Bilateral Electric Transcranial Stimulation.jpg|'''Figure 1b:''' Motor-evoked potential symmetry in masseter muscles.
File:Jaw Jerk .jpg|'''Figure 1c:''' Jaw reflex test confirming functional balance.
File:Mechanic Silent Period.jpg|'''Figure 1d:''' Mechanical silent period indicating neuromuscular coherence.
</gallery>


=== What you’ll learn ===
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.
* How complexity science reframes occlusal stability. 
* Why “malocclusion” is often an insufficient label.
* The clinical role of Occlusal Dysmorphisms in rehabilitation.
