Denture Retention and Stability

Denture retention and stability are crucial for the success of any denture treatment. Retention refers to the ability of the denture to stay in place during normal activities, while stability refers to the denture’s resistance to movement or displacement. Understanding the factors that contribute to denture retention and stability is essential for dentists and patients alike.

Mechanisms of Denture Retention

Denture retention relies on a combination of physical and mechanical principles. The primary mechanisms include:

• Adhesion: This occurs due to the attraction between the denture base and the moist tissues of the mouth. The saliva acts as a lubricant, creating a thin film that helps the denture adhere to the tissues.
• Suction: When the denture is placed in the mouth, air is trapped between the denture base and the tissues. As the denture is seated, the air is displaced, creating a negative pressure that helps hold the denture in place.
• Mechanical Retention: This involves the use of physical structures, such as clasps or attachments, to secure the denture to the remaining teeth. These structures help prevent the denture from dislodging during chewing or speaking.

Denture Adhesives

Denture adhesives are topical products that can enhance denture retention by increasing adhesion between the denture base and the tissues. They work by filling in gaps between the denture and the tissues, creating a smoother surface that reduces friction and improves the seal. Denture adhesives can also help to cushion the denture, reducing discomfort and irritation.

Common Problems Related to Denture Retention

Several factors can contribute to poor denture retention, including:

• Loss of Bone: As we age, the jawbone can shrink, leading to a decrease in the area available for denture support. This can make it difficult for the denture to stay in place.
