Acid-etched, resin bonded cast metal prostheses: a retrospective study of 5- to 15-year-old restorations.
Eighty-five resin bonded prostheses were evaluated in a retrospective study over a 15-year period. All had been in function for at least 4.5 years. Multifactorial variables were studied to ascertain their effect on debonding and the health of the oral tissues. The results showed: (1) the caries rate of the retainer teeth was 6%, (2) the mean gingival indices for the prostheses were significantly higher (P > .0001) than those of the remaining dentition, (3) 61% of the restorations had not debonded (if failure resulting from trauma was not included, the incidence of debonding dropped to 19%), and (4) all patients liked their prostheses.
