PMMA are polymerized by different methods such as autopolymerization
, photopolymerization, microwave polymerization and thermopolymerization but autopolymerization
technique is commonly used in dentistry due to clinical applications and fast setting.3
After the impression copings were screwed onto the implants and verified with radiographs for complete seating, the copings were joined together by lacing the floss across the copings in a figure of "8" and subsequently strengthened with autopolymerization
resin (GC Pattern Resin, Japan).
of methyl methacrylate during its preparation can cause thermal damage to the underlying brain due to its exothermic reaction.
Although the [Cu.sup.2+]-primary amine redox process is deemed as a monocenter initiation, chain transfer of primary radicals (-NH*) and propagating radicals (PMMA*) to DMSO/DMF or MMA, or thermally induced autopolymerization
of MMA may lead to free PMMA chains.
The contact between ED Primer and resin cement accelerates the autopolymerization
reaction of this material.
