Abstract
In order to achieve success in the fabrication of fixed prostheses, an appropriate marginal fit is mandatory. Despite the
technological advancements in terms of the improvement of casting techniques, die fabrication, waxing pattern and
coping fabrication, a discrepancy remains between the restoration’s margin and the cervical edge of the prepared tooth.
The purpose of the study was to evaluate the casting accuracy by axial coverage of the die spacer 1.00 mm short from the
finish line. Efforts were made to select and utilize standard method. Increased casting accuracy with die spacer
application short by 1.00 mm from finish line could be due to the reason that unpainted area will ensure an area of close
adaptation at the margin. Irrespective of the method of the die spacer application, all the castings showed deficiency in
the marginal fit. application of die spacer 1.00 mm short from finish line on the die is beneficial to reduce the discrepancy
in marginal fit and also to reduce the exposure of the cement at the margins.
