Aim: To evaluate and compare the marginal accuracy of multiple unit cast restorations fabricated by Conventional and Ringless casting technique. Method: A forty standardized wax patterns are fabricated on a type IV stone replica of a multiple unit stainless steel die with standardized pontic space. The wax patterns are divided into four groups. Group IA: Ringless casting with conventional wax elimination method. Group IB: Ringless casting with accelerated wax elimination method. Group IIA: Metal ring casting with conventional wax elimination method. Group IIB: Metal ring casting with accelerated wax elimination method. The vertical marginal gap was measured at six sites per sample, using a digital optical microscope at 6.25X magnification. Result: The mean vertical marginal gaps of castings fabricated using ringless groups IA and IB (274.9±131.6 µm) were signiﬁcantly less (p < .004) than those castings fabricated using the ring casting groups IIA and IIB (379.9± 106.9 µm). The conventional wax elimination groups (IA, IIA) showed higher vertical marginal discrepancies (393.8±116.6 µm) than the accelerated wax-elimination groups (IB, IIB) (215.9±73.02 µm); however, the difference was not statistically signiﬁcant (p < 0.05). Conclusion: The ringless casting technique can produce accurate and acceptable multiple-unit restorations in ﬁxed prosthodontics.
