PARKELL'€™s economical MucoSoft® reline system features a silicone elastomer that won'€™t stiffen with age, so the denture retains its cushioning resilience long-term. In addition, the material'€™s hydrophobic formula reduces water absorption, so there'€™s less discoloration and odor. Its resin additives reinforce it for enhanced tear-resistance. The proprietary MucoSoft® bonding liner is derived from a molecule synthesized in the company'€™s laboratory and chemically grafts the soft reline material to the old acrylic denture base to resist peeling and leakage.
