Abstract
Full veneer cast crowns were made from stone dies obtained from vinyl polysiloxane impressions using custom trays. The marginal discrepancies between the crowns and the stone dies or original metal die were measured. The inside discrepancies between the crowns and the original die were also obtained by measuring the thickness of silicone fit checking material. Although the crowns adjusted to the stone dies revealed small marginal discrepancies on the stone dies as compared to the crowns as cast, both crowns had the same marginal adaptation and thickness of the fit checking material on the original die. The vent holes on the tops of the crowns for the fit checking material revealed the almost same axial discrepancies as compared to the cement thickness reported in the other studies. Both measurements of marginal and inside discrepancies detailed the fit of cast crowns.
