    Abstract:
    Debonding of plastic teeth from its denture base has been frequently experienced in our prosthetic practice. Three of nine products investigated have fulfilled the requirements for bonding according to ISO test 3336. Loading forces necessary to produce fractures varied between 170-810 N within the tooth and 80-230 N at the tooth-denture base interface. Comparative significances were noted for the mean breaking force against fracture and debonding when comparing the resistance of "Acry Rock" to the other eight materials tested. Maximizing the extension of the polymerization surface through a larger surface area of individual teeth seemed to be a significant factor in the determination of the debonding force necessary to produce fracturing.
