title: [Stress analysis with a laser microscope analyzer for acrylic base resin]
abstract: Acrylic resin are applied widely as a denture resin,its residual stress is closely related with aging and mechanical properties of denture resin.The authors tested the stress level of the base resin with a laser microscope stress analyzer in the study.The results indicated that there was not statistical differences between two curing methods is in water bath or under pressure.The residual stress in base resin can be concentrated at the area near to clasp wire which was embedded in base resin for reinforcing strength of denture base.The vibration caused by grind with stone wheel or impact in disc lasting with a hammer may increase the stress level in base.The authors pointed out some methods for reducing residual stress resin.
