Bonding of different soft lining materials has been widely investigated, but there is little work on the effect of using different denture base resins. This study investigates the bonding of Molloplast-B (a heat-cured, silicone soft lining material) and five commercial acrylic denture base materials of different types (Pacton, Lucitone, Meliodent, Ivocap and Compresin). The lining was processed against all the resins cured and Pacton, Lucitone and Meliodent uncured. In the cured specimens, Lucitone, Meliodent and Compresin demonstrated cohesive failure, whereas Pacton and Ivocap demonstrated part-adhesive and part-cohesive failure. All three sets of uncured specimens demonstrated adhesive failure. It was concluded that pre-curing, roughening and treating with Primo adhesive gives a better bond.

D003819 Denture Bases The part of a denture that overlies the soft tissue and supports the supplied teeth and is supported in turn by abutment teeth or the residual alveolar ridge. It is usually made of resins or metal or their combination. Base, Denture,Bases, Denture,Denture Base
D003822 Denture Liners Material applied to the tissue side of a denture to provide a soft lining to the parts of a denture coming in contact with soft tissue. It cushions contact of the denture with the tissues. Cushion Liners,Cushion Liner,Denture Liner,Liner, Cushion,Liner, Denture,Liners, Cushion,Liners, Denture
D004129 Dimethylpolysiloxanes Silicone polymers which consist of silicon atoms substituted with methyl groups and linked by oxygen atoms. They comprise a series of biocompatible materials used as liquids, gels or solids; as film for artificial membranes, gels for implants, and liquids for drug vehicles; and as antifoaming agents.

D012826 Silicone Elastomers Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.
