Effect of the curing cycle on residual monomer levels of acrylic resin denture base polymers

Cytotoxicity of Two Autopolymerized Acrylic Resins Used in Orthodontics

“…Stafford and Brooks 10 verified that residual monomer content is usually around 1.5% to 4.5% in self-curing acrylic resins, but for heat curing it is only around 0.3% when submitted to the cycle proposed by Huggett et al 11 Davy and Braden 12 even found levels of residual monomer between 0.045% and 0.18%. Harrison and Huggett 13 referred to the British Standard Specifications for selfcuring orthodontic resins, which establishes 3.5% as a limit to residual monomer concentration. Yilmaz et al 14 mentioned the international patterns of ISO 1567 as a reference.…”

Various curing methods on transverse strength of acrylic resin

“…The residual monomer then can cause plasticizing effect, reduced acrylic resin strength, and cause many alteration because of pressure. 12 Similarly, another researcher also found that acrylic resin cured in water-bath for long period can cause acrylic resin to react as plasticizer, can reduced glass transition temperature (tg), and can make its mechanical character decreased. 13 Moreover, the cycle of curing process was successfully conducted for making the acrylic resin denture base in many sizes, forms, and depths when the curing process was conducted at 70° C for less than two hours and then continued at the temperature of 100° Celsius for more than one hour.…”

The Use of Microwave Energy to Polymerize Acrylic Resins

“…[29][30][31][32][33][34] Bunun yanısıra, artık monomer konsantrasyonu, protez kaidesi akrilik rezinlerinin mekanik özelliklerinin belirlenmesinde önemli bir parametredir. 35 De Clerk 2 mikrodalga enerjisi ile polimerizasyon yöntemi ile konvansiyonel su banyosu yöntemini kıyaslayarak mikrodalga polimerizasyonunda daha düşük seviyelerde artık monomer bulduklarını rapor etmiştir.…”
