Denture Base Materials Curing (Polymerization): After final closure, the flask is kept at room temperature for 30 to 60 minutes (bench curing). Bench Curing In Dentistry Purpose of Bench Curing: Permits an equalization of pressure throughout the mold. It allows time for more uniform dispersion of monomer throughout the mass of dough, since the last material … [Read more...] about Denture Base Materials & Curing Cycles

Porosity In Denture Resins, Tissue Conditioners The heating process used to control polymerization is called as curing or polymerizing cycle. This process should be well controlled to avoid effect of uncontrolled temperature rise, such as boiling of monomer and denture base porosity.' "Importance Of Reducing Porosity In Denture Materials" The curing cycle is the … [Read more...] about Porosity In Denture Resins,Tissue Conditioners

Soft Liners In Dentistry Soft liners are soft cushion like liners which are given to the denture base to absorb some of the energy produced by masticatory impact and to distribute the forces of mastication more evenly. Types Of Denture liners Short-term soft liners (ISO 10139 Part 1) Long-term soft liners (ISO 10139 Part 2) 1. Short-term Soft Liners: They are … [Read more...] about Soft Liners in Dentistry: Types, Composition, Uses, and Benefits

Tissue Conditioners Tissue conditioners are for the short time use only, i.e. for few days only. Most commonly PMMA soft lining materials are used on the tissue surface of dentures to act as tissue conditioner. Composition Of tissue conditioners Powder: Polymethyl methacrylate polymer beads Liquid: Ethyl alcohol—solvent; Butyl phthalate/butyl glyco- … [Read more...] about Tissue Conditioners in Dentistry

Heat Cure Versus Cold Cure Partials Composition Of acrylic resin: Heat Activated: Available as powder and liquid: The powder may be transparent or tooth-colored or pink (to stimulate the gums some even contain red fiers to duplicate blood vessels). The liquid is supplied in tightly sealed amber-colored bottoms (to prevent premature polymerization by light or UV … [Read more...] about Heat Cure Versus Cold Cure Partials
