Aetiology of Malocclusion: General and Local Factors

This course explores the diverse factors contributing to the development of malocclusion. It is structured into two primary categories: General Factors, which involve systemic, hereditary, and environmental influences, and Local Factors, which focus on dental anomalies such as tooth size, premature loss, and eruption paths. Understanding these aetiological factors is essential for accurate diagnosis and effective treatment planning.

About Course

This course provides a comprehensive introduction to the aetiology of malocclusion, focusing on both general and local factors that contribute to the development of malaligned teeth and abnormal occlusion. Learners will explore the genetic, systemic, environmental, and local influences affecting craniofacial growth and dental development. The course highlights the underlying causes of malocclusion to support accurate diagnosis, prevention, and early intervention. It is designed for dental and orthodontic learners seeking a strong foundation in the causes of malocclusion.

What You'll Learn

By the end of this course, you will be able to: 

  • Classify the aetiological factors.
  • Identify the hereditary and congenital general factors that influence dental development.
  • Explain how environmental influences and pressure habits act as general aetiological agents for malocclusion.
  • Assess the impact of local factors, such as anomalies in tooth number and shape, on occlusion.
  • Analyze how the premature loss or prolonged retention of primary teeth contributes to malocclusion.
  • Differentiate between systemic (general) and dental (local) causes during a clinical examination

Prerequisites

To be successful in this course, learner should be able to:

  • Identify the normal sequence of tooth eruption and the characteristics of a stable primary, mixed, and permanent dentition.
  • Classify dental relationships according to Angle’s system to distinguish between normal occlusion and malocclusion.
  • Recognize the morphological differences between teeth (e.g., supernumerary teeth or peg-shaped laterals) that serve as local aetiological factors.
  • Explain how premature tooth loss or abnormal pressure habits interfere with alveolar bone development.

Who Can Take This Course?

  • Dental Students: to recognize the clinical signs of developing malocclusion during routine exams.
  • Orthodontic Residents (PGs): Mastering the differential diagnosis between genetic (General) and environmental (Local) causes to predict treatment stability.
  • General Dentists: Focusing on the early detection of local factors to ensure timely orthodontic intervention and referral.
