Abstract
Acrylic resin denture base material has been available to the dental profession for over 60 years, and although materials with superior properties have been on the market for some time, it still remains the most popular choice of clinicians. The requirement of the simple processing equipment and low cost of the fabrication process are the reasons for its continued popularity. However, debonding of acrylic teeth from denture base resins remains a problem for both patients and clinicians. The failure rate of acrylic dentures resulting from fracture has been reported to be unacceptably high, with the most prevalent type of failure documented being debonding or fractures of the teeth A series of studies have attempted to determine the quality of denture tooth bonding produced by commonly employed dental laboratory conditions. The present study was under taken to evaluate and compare the effects of chemical and mechanical treatment of the ridge lap surface of acrylic teeth on the bond strength of acrylic resin teeth to denture base resins.
