About hard reline materials
Hard reline materials are typically based on PMMA chemistry and are used for long-term restoration of denture fit and function. Recent hard chairside reline resins contain methacrylate monomers of greater molecular weight than methyl methacrylate.
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
- Repair Acrylics — The acrylic used to mend a cracked or broken denture.
- Hard Reline Materials — A hard acrylic lining for the long term.
- Soft Reline Materials — Stays resilient; silicone liners, which have no plasticizer, keep their cushioning longer than acrylic ones.
- Tissue Conditioners — A soft liner for the short term, while the tissue heals.
- Reline & Repair Accessories — The jigs used for a laboratory reline, not the lining material.
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.
