<b><i>Purpose</i> : </b>This study evaluated the marginal fit of fixed bridges constructed using accelerated-type gypsum-bonded investment and compared them with fixed bridges constructed using conventional-type investment.<br><b><i>Materials and Methods</i> : </b>Four types of accelerated-type gypsum-bonded investment and one type of conventional-type investment were used. A three-unit fixed bridge was cast in 12% gold-silver-palladium alloy and Type III gold alloy using different types of investment. Each bridge was seated in the master die, and the margins were inspected via microscopy.<br><b><i>Results</i> : </b>The results failed to show any significant differences between the bridges constructed from either alloy using the accelerated gypsum-bonded investment and those constructed using the conventional investment. In most of the investments, the gold bridges had slightly smaller marginal gaps than the 12% gold-silver-palladium alloy bridges, but the differences were not significant.<br><b><i>Conclusion</i> : </b>The results obtained indicated that the fit of fixed bridges made in accelerated gypsum-bonded investment is similar to that of bridges made in conventional investment.
