Structured Abstract
This narrative review surveys current research demonstrating how oral dysfunction
can escalate into malocclusion, acquired craniofacial disorder and contribute to
generational dysfunction, disorder and disease.
Introduction: Baseline orthodontic consultations are generally recommended
beginning age seven. However, the dysmorphic changes that result in malocclusion
are often evident years earlier. Similarly, following orthodontic treatment, patients
require permanent retention when the bite is not stable, and without such retention,
the malocclusion can return.
Setting and Population: Narrative review article including research on infants,
children and adults.
Materials and Methods: This review is a brief survey of the symptomology of orofacial
myofunctional disorder and outlines 10 areas of oral function that impact occlusal
and facial development: breastfeeding, airway obstruction, soft tissue restriction,
mouth breathing, oral resting posture, oral habits, swallowing, chewing, the impact of
orofacial myofunctional disorder (OMD) over time and maternal oral dysfunction on
the developing foetus.
Conclusion: Malocclusions and their acquired craniofacial dysmorphology are the
result of chronic oral dysfunction and OMD. In order to achieve long-term
stability of
the face, it is critical to understand the underlying pathologies contributing to
malocclusion, open bite and hard palate collapse.
