Clinical Performance of Composite Using Direct and Indirect Technique
AIM: This study aimed to evaluate and compare clinical performance of composite in regard to colour, marginal staining, surface roughness and chipping in anterior teeth using direct and indirect technique.
MATERIAL AND METHODS: 60 anterior teeth were selected for this study and were randomly divided into 2 groups. Facial reduction of 0.75-1 mm was done in both groups. In Group A (n=30), veneer preparation was done directly by incremental layering technique. In Group B (n=30), putty impression was taken, a cast was made and composite build up was performed on the cast. The prepared veneer was placed into visible light cure chamber for uniform curing. It was then loaded with the luting cement and gently seated on labial surface. Veneers were evaluated at baseline, 3, 6 months for colour stability, marginal staining, surface roughness and chipping according to modified USPHS criteria (Ryge’s criteria). Score of Alpha, Bravo and Charlie were assigned, and the results were statistically analysed using Chi square test.
RESULT: No statistical difference was found in Group A and B at 0, 3, 6 months in all parameters.
CONCLUSION: Clinical performance of direct and indirect technique for composite curing was found similar in the present study.
