Retention strengths of three cements using full crown preparations restored with amalgam.
The tensile bond strength of noble and non-noble castings luted with adhesive resin cements and zinc phosphate cement to prepared extracted teeth having received MOD amalgam restorations were compared. The crown preparations were standardized on the extracted teeth to produce axial wall length and taper consistent with that seen clinically. Results indicated the resin luting agents were significantly more retentive than the zinc phosphate cement and for each cement there was no difference in the casting alloy used.
