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 new uses of the material. Where the invention involves a lining over a void in an acrylic denture, the resultant mixture is applied over the underlying surface of the acrylic over the void to chemically and mechanically bond the mixture in a seamless bond to the underlying surface of acrylic. 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. Where the method is used to apply a liner around an implant cylinder or an implant healing cap anchored into a jaw bone the resultant mixture is applied around the surface of the implant or healing cap for forming a liner or gasket. The sealer component is then applied over the liner to create a nonabsorbent 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 toughening 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.
