What is denture hyperplasia most often attributed to?

Denture hyperplasia, also known as denture-induced fibrous hyperplasia, is most often attributed to denture movement. This condition arises when a denture does not adequately fit the contours of the oral tissues, leading to friction and irritation during normal functions such as speaking and chewing. As the denture shifts, it continuously rubs against the soft tissues of the mouth, causing chronic irritation and resulting in an inflammatory response that can promote the development of fibrous tissue.

A properly fitting denture should remain stable during use, minimizing movement and reducing the risk of irritation. While factors like poor oral hygiene, improper sizing, and excessive wear can contribute to discomfort and complications with dentures, the primary culprit in the case of denture hyperplasia is the lack of a secure fit that leads to excessive movement and trauma to the underlying tissues. Thus, addressing denture movement through proper fitting and adjustment is crucial in preventing this condition.
