Lang Flexacryl Hard Reline Acrylic Liquid Refill is an acrylic resin specifically formulated for hard denture reline procedures. This material is intended for professional application, providing a durable reline for existing dentures in both clinical and laboratory settings.
This 8oz liquid-only refill bottle is designed for dental professionals who require a separate supply of the liquid component for their Flexacryl Hard system. It suits practices and laboratories that manage their acrylic components independently, or need to replenish their liquid stock for ongoing reline work.

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.
- Heat-Cure Denture Resin — Acrylic powders, liquids and kits filed under the heat-cure name as well.
- Self-Cure Denture Resin — Self-curing acrylic powders, monomer liquids and kits.
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.
