A study on the effect of finishing line depth on the strength of Feldspathic ceramic in dental clinic

CAD/CAM dental restoration had become a sequence of digital tool and software to perform best esthetic with strong material. The effect of only three marginal thickness (0.5,1.0 and 1.5mm) on fracture strength of feldspathic ceramic (FSC) ceramic have been deal within present project Thirty-six (36) die model were tested in separate, fracture load has been carried out until catastrophic failure occurred using low speed video recorder. Range of variation at the values exceed 2000N for all the three sets whereas the mean value of fracture strength for 0.5,1.0,1.5 mm marginal thickness was 1873,2028 and 1296 N respectively. Standard deviation and coefficient of variance were calculated for the result. The influence of these three-finishing line depth on fracture strength of FSC was not so clear. Still applying FSC is promising for prosthodontic restoration as an alternative to the previous metal ceramic. Future studies could lead to more precise answer to the most suitable finishing line.
