Abstract
Purpose: To evaluate 2D and 3D of occulsal, mesial-occlusal and mesial-occlusal-distal cavity of composite resin inlay.
Methods: Abutment tooth 16, 36 of FDI system was selected for the study. Inlay prostheses classified as occlusal cavity (OC group), mesial-occlusal (MOC) and mesial-occlusal-distal cavity (MODC) were prepared using composite resin. Composite resin was injected with composite resin in prepared tooth cavity and then photopolymerized with UV light. Additional thermal polymerization was performed. Marginal gap of composite resin inlays were measured by digital microscope(x160) with silicone replica technique. The data was analyzed from statistical software for Kruskal-Wallis test (α=0.05). 3-dimensional analysis was analyzed through superimposition method.
Results: The smallest 2D marginal fit measure of the three groups was 47.0±21.6 μm in the MOC group. The largest 2D marginal was 69.1 ± 33.8 μm in the MODC group. In the trueness of the three groups, the most accurate figure was 14.4±2.3 μm for the MODC group. In Precision, the most accurate figure was 14.5±4.3 μm for the MODC group.
Conclusion : In this study, 2D marginal fit of OC, MOC, and MODC cavities fabricated with composite resin was applicable to all clinical applications. In the 3D inner surface accuracy evaluation, the MODC group showed the accuracy results.
