What can excessive force lead to in periodontal tissues?

Excessive force applied during orthodontic treatment can significantly impact periodontal tissues, leading to a variety of detrimental effects. When too much force is exerted on teeth, it can result in tissue injury characterized by root resorption, inflammation, or necrosis.

Root resorption occurs when the external surface of the tooth root is dissolved, potentially leading to permanent loss of tooth structure. Inflammation may develop due to the trauma inflicted on the periodontal ligament and surrounding tissues, which can compromise their health and functionality. Necrosis refers to the death of tissue, which can occur if the blood supply is disrupted by excessive force, thus impairing the tissue's ability to heal and maintain its integrity.

In contrast, other options do not accurately reflect the consequences of excessive force. While one might think that excessive force could lead to improved stability or accelerated healing, the reality is that appropriate and controlled forces are necessary for gradual movement and healing without causing damage. Hence, understanding the balance of applied force is crucial in orthodontic practice to avoid these negative outcomes on periodontal health.
