Effect of sintering temperature on the color of Bloomden 3D monolithic zirconia.
1. Experimental Sample,Avadanlıq,Parametr
Örnək:Bloomden Products 3D-pro-ml-A1,3D-pro-ml-A2,3D-pro-ml-A3
Avadanlıq:Bloomden Sintering Furnace Model#:B1700
Experiment comparison of sintering sistemi:
a. Bloomnden 3D series products recommended sintering temperature curve
b. 1530℃sintering temperature curve
2. Experiment result and conclusion

3D-pro-ml-A3
3D-pro-ml-A2
3D-pro-ml-A1
Conclusion:As experiment result, 1480℃ is more recommend sintering temperature than 1530℃.At the sintering temperature of 1530℃ ,all color of 3D-pro-ml-A1,3D-pro-ml-A2 and 3D-pro-ml-A3 are lighter than 1480℃.After sintered at 1530℃,the color of 3D-pro-ml-A3 tooth is more like A2, and 3D-pro-ml-A1 and 3D-pro-ml-A2 is lighter than A1 on color sheet.
3. Analysis and Suggestion
Analiz:As result of the material of 3D series products is a multi-powder mixture and it`s contain many high permeability UT powder.Considering the suggested sintering temperature range of UT powder is 1430°C——1480℃,which is much lower than 1530℃.Therefore,when sintered products at 1530℃ will cause abnormal growth of zirconia crystals in the product and affect the color of the product.
Sugesstion :We recommend 3D products are sintered at temperature of 1480℃,and the temperature range should not exceed 1450℃ - 1500℃.
