Background: Die silicone is used for making dies for chair side fabrication of inlays and onlays. Die silicone material is user friendly and fast setting but undergoes shrinkage. Aim: To compare the dimensional stability between Die stone and Die Silicone. Methods: A metal die with known dimensions is made. Impressions of the metal die are made with Polyether impression material. Dies are made out of Die Stone and Die Silicone. The Dimensions of the reproduced details are measured and compared. Results: Both Die Stone and Die Silicone produce comparable results. Conclusion: As Die Silicone is made of Polymer, its dimensional stability is a query. But in the study it was found that, they had similar results. With the advantages of fast setting, chipping and abrasion resistance, it would make Die Silicone a more user friendly material of choice for die making.
