Аннотация
Glass ionomer, polycarboxylate, zinc phosphate, and two resin cements were tested in vitro to cement base and noble metal crowns to prepared extracted teeth. The cements had different retentive characteristics. Among cements, statistically significant tensile resistance to dislodgment in order of decreasing strength was: (1) C & B Metabond (resin); (2) Panavia (resin); (3) Fuji I (glass ionomer); (4) Durelon (polycarboxylate); and (5) Fleck's (zinc phosphate). Tensile resistance to dislodgment did not differ statistically among base and noble metal crowns cemented with glass ionomer, polycarboxylate, or zinc phosphate cements. Tensile resistance to dislodgment differed statistically among base and noble crowns cemented with the resin cements (C & B Metabond and Panavia); the base metal crowns had the highest rate of retention.
