COMPARATIVE IN VITRO EVALUATION OF FLEXURAL STRENGTH AND HARDNESS OF THREE FIXED PROSTHODONTICS PROVISIONAL CROWN MATERIALS
Dr. Shilpa. S. Dandekeri
Abstract :
Objectives: To evaluate and compare the flexural strength and hardness of three provisional crown after storing in artificial saliva and testing at intervals of 10 days.
Study design: A metal master mould was faicated to obtain samples of standard dimensions. The three provisional crown materials that will be tested in this study are Protemp™ IV (group PSC),Combo– LignTM (group CDC),and TempronTM (TSC). The specimens were tested for flexural tests were using universal testing and the micro hardness using microhardness tester. Statistically analysed by ANOVA test.
Results : Flexural test results showed that Group PSc (105.78 MPa) has the highest flexural strength followed by Group CDC (80.90 MPa), Group TSC (69.67 MPa). The hardness tests showed that Group CDC (95.40 KHN) has the highest hardness value followed by Group PSC (69.10 RHN), Group TSC (47.80 KHN) .
Conclusion: Group PSC showed the highest flexural strength compared to others,and Group PSC.
