Properties of denture liners - A review

Abstract

Denture liners are the materials applied to the tissue side of a denture coming in contact with the soft tissue. It cushions the contact of the denture with the tissues. The usage of the denture liners is to alleviate the trauma associated with complete dentures. The failure in adhesion, changes in rough surfaces and hardness are the favourable factors for microbial accumulation and compromise the liner’s durability and causes the oral health conditions like denture stomatitis. The adhesion can be improved with the usage of different substances and surface treatments. The changes in the rough surface and hardness can compromise the material’s lifespan. This review deals about the properties of adhesion, roughness and hardness of the denture liners.
