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. | |||
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 | |||

}} 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. | |||
{{q2|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.<ref>{{cita libro | |||

}} Jan-Feb; 23(1) 71–78.</ref> 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: | |||

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. | ||

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. | |||
<blockquote>''Occlusal Dysmorphisms, not simply Malocclusion — an entirely different paradigm.''</blockquote> | |||
