BACKGROUND
Achieving optimal marginal fit is essential for the success of Virgilite Based Lithium Disilicate Ceramic crowns.
MATERIALS AND METHODS
In this study, we compared the marginal fit of Virgilite Based Lithium Disilicate Ceramic crowns using two different CAD/CAM scanners, powder free (System A, Omnicam) and powder based (System B, Blue cam).
RESULTS
The mean marginal gap for System A was found to be 63.5 μm (standard deviation ± 10.2 μm), while for System B, it was 57.8 μm (standard deviation ± 9.8 μm). System B demonstrated a slightly superior marginal fit compared to System A, with a difference of 5.7 μm.
CONCLUSION
Within the limitations of this study, it can be concluded that both Omnicam and Blue cam produced clinically acceptable marginal fit of Virgilite Based Lithium Disilicate Ceramic crowns. However, Blue cam exhibited a slightly better marginal fit compared to Omnicam. Further clinical studies are warranted to validate these findings.
背景
实现最佳边缘适合度对于基于Virgilite的二硅酸锂陶瓷冠的成功至关重要。
材料与方法
在本研究中，我们使用两种不同的CAD/CAM扫描仪，即无粉（系统A，Omnicam）和基于粉末（系统B，Blue cam），比较了基于Virgilite的二硅酸锂陶瓷冠的边缘适合度。
结果
发现系统A的平均边缘间隙为63.5μm（标准差±10.2μm），而系统B的平均边缘间隙为57.8μm（标准差±9.8μm）。系统B的边缘适合度略优于系统A，相差5.7μm。
结论
在本研究的局限性内，可以得出结论，Omnicam和Blue cam都能产生临床上可接受的基于Virgilite的二硅酸锂陶瓷冠的边缘适合度。然而，Blue cam的边缘适合度略优于Omnicam。需要进一步的临床研究来验证这些发现。
