Attritional Occlusion: Causes, Effects, and Orthodontic Management, Study notes of Orthodontics

Rajiv Gandhi University of Health SciencesOrthodontics

A comprehensive overview of attritional occlusion, a pattern of tooth wear caused by normal or excessive mechanical friction between the teeth. It discusses the key factors contributing to attritional occlusion, including bruxism, aging, diet, and malocclusion. The adverse effects of attritional occlusion, such as tooth sensitivity, discomfort, and problems with chewing and alignment, are also highlighted. The document delves into the role of orthodontics in managing attritional occlusion, focusing on the importance of correcting malocclusion, restoring occlusal function, preventing further attrition, and maintaining long-term retention. It emphasizes how orthodontic treatment can have a positive impact by addressing the underlying bite issues that contribute to attritional occlusion, ultimately helping patients preserve their teeth and improve their overall oral health.

ATTRITIONAL OCCLUSION
Attritional occlusion refers to the pattern of tooth wear that occurs as
a result of normal or excessive mechanical friction between the
teeth. This wear, or attrition, happens when the surfaces of the teeth
grind against each other, often during chewing or clenching. Over
time, the continuous grinding and friction can lead to the loss of
tooth enamel, changes in tooth shape, and may affect the occlusal
surfaces.
Key factors that contribute to attritional occlusion include:
1. Bruxism: Habitual grinding or clenching of teeth, especially
during sleep.
2. Aging: Natural tooth wear that occurs with aging due to years
of use.
3. Diet: Consumption of hard or abrasive foods can accelerate
tooth wear.
4. Malocclusion: Misalignment of teeth can lead to uneven or
excessive wear on certain areas of the teeth.
ADVERSE EFFECTS –
Tooth sensitivity
Discomfort
Problems with chewing and alignment
which may require restorative dental treatments like crowns or
dental bonding to rebuild the damaged teeth.

ATTRITIONAL OCCLUSION

Attritional occlusion refers to the pattern of tooth wear that occurs as a result of normal or excessive mechanical friction between the teeth. This wear, or attrition, happens when the surfaces of the teeth grind against each other, often during chewing or clenching. Over time, the continuous grinding and friction can lead to the loss of tooth enamel, changes in tooth shape, and may affect the occlusal surfaces. Key factors that contribute to attritional occlusion include:

  1. Bruxism : Habitual grinding or clenching of teeth, especially during sleep.
  2. Aging : Natural tooth wear that occurs with aging due to years of use.
  3. Diet : Consumption of hard or abrasive foods can accelerate tooth wear.
  4. Malocclusion : Misalignment of teeth can lead to uneven or excessive wear on certain areas of the teeth. ADVERSE EFFECTS –  Tooth sensitivity  Discomfort  Problems with chewing and alignment which may require restorative dental treatments like crowns or dental bonding to rebuild the damaged teeth.

In orthodontics, attritional occlusion refers to the wear and tear on teeth that occurs due to abnormal occlusal forces, often resulting from malocclusion or improper bite patterns. When teeth do not fit together correctly, excessive or uneven forces can be exerted on certain teeth during chewing or grinding, leading to accelerated tooth wear – attrition. Key Aspects of Attritional Occlusion in Orthodontics:

  1. Malocclusion : Misaligned teeth or improper jaw alignment can cause certain teeth to bear excessive pressure, leading to premature or uneven tooth wear. Examples: o Crossbite o Overbite o Underbite o Open bite
  2. Bruxism : Patients with malocclusion may also develop bruxism, further accelerating attrition. Bruxism is common in individuals with bite issues, especially during sleep.
  3. Orthodontic Treatment Goals : o Correcting Alignment : Achieving proper alignment and occlusion helps distribute biting forces evenly across all teeth - reducing the risk of excessive wear.
