Denture bases have been fabricated using acrylic reins. Though acrylic resin has many advantages such as easy processing / curing, but has a limitation of final contraction during curing. This movement of teeth results in disturbed occlusion causing unstable dentures The movement of teeth may occur as a result of processing procedures and dimensional changes of acrylic denture base during curing, deflasking, finishing and polishing. This book compares two curing methods for acrylic to prevent minimum tooth movement in polymerised acrylic denture bases.
