About tissue conditioners

A tissue conditioner is a resilient liner placed in a removable prosthesis for a short time to allow the tissue to heal. Its plasticizers leach out in saliva or water, so its clinical life is often limited to a few weeks.

Relining resurfaces the tissue side of a removable denture with new base material so that it fits the mouth accurately again. Rebasing is the laboratory process of replacing the entire denture base on an existing prosthesis. A denture is relined in the laboratory or at the chairside, where a self-curing reline resin is used directly in the mouth.

The FDA regulates denture relining, repairing or rebasing resin as a Class II device that is not available over the counter (21 CFR 872.3760).

How reline materials, tissue conditioners and repair acrylics differ
What to look at when choosing a reline material

Where it is processed: liners are made as laboratory-processed and as chairside materials, hard and soft.

Bond to the base: adequate bond strength between the reline resin and the denture base is essential to prevent microbial growth at the junction, staining and delamination.

Softness over time: the main issue with acrylic soft liners was the gradual loss of softness caused by plasticizers.

Standard: ISO 10139-2 sets requirements for the softness, adhesion, water sorption and water solubility of soft liners for long-term use.
