MDS AIPGDEE preparations B-IDS : Mode of failure during dislodgement-of prosthesis cemented with zinc poly carboxylate cement

Mode of failure during dislodgement-of prosthesis cemented with zinc poly carboxylate cement is usually seen at the
a. Cement tooth interface
b. Cement prosthesis interface
c. Cleavage through the cement layer
d. Fracture of tooth or prosthesis

Ans 26 B Cement prosthesis interface                                 

Failure of Zinc phosphate cement occurs at cement -tooth interface

Failure of Zinc poly carboxylate cement occurs usually at cement-metal (prosthesis) interface.
