ABSTRACT:
A known elastomeric non-methyl methacrylate soft material has been used as a soft denture liner material. The material includes powder and liquid components which are mixed together and cured. The invention involves lining an underlying surface of an acrylic overdenture, wherein the overdenture is applied over a crown coping over a tooth or over a post with a ball or hour-glass shaped abutment. A liner is formed having the characteristics of being flexible, resilient, shape retentive, hydrophobic, soft, spongy and cushiony. A known sealer component is then applied over the liner to create a non-absorbent exterior surface seal and glaze. By varying the powder to liquid ratio, the material can be made more dense thus hardening or softening it for various applications. By removing the exterior surface and roughening the material, it can easily be adjusted, repaired or refurbished. The material allows for a quick cure or a dental laboratory processed cure and is compatible for either chairside or laboratory use.
