[Marginal fit changes in implant-supported prosthetic bars by electroerosive processing]

The aim of the study was to evaluate the marginal fit changes in implant supported prosthetic bars by electroerosive processing. The experimental model included 9 bars supported by 2, 4 and 6 implant analogues (3 bars for each number of supports). Marginal gap size was assessed by digital microscopy before and after electroerosive processing conducted in 3 stages (10, 8 and 5 minutes long). Electroerosive processing proved to be useful tool for marginal fit correction.
