| Abstract | ||||
| Purpose: This study was conducted to evaluate the influence of air born-particle abrasion using three sizes of AL2O3; (50 μm, 110 μm, 150μm) on translucency and flexure strength of resin nano-ceramic (Lava Ultimate) material. Materials andMethods Forty samples were divided into 4 groups (n=10) according to the type of surface treatment conducted: Group (1): Lava Ultimate samples with no surface treatment (control group), Group (2): Lava Ultimate samples air- abraded withAL2O3 particle size 50μm, Group (3): Lava Ultimate samples air- abraded with AL2O3 particle size 110μm and Group (4): Lava Ultimate samples air-abraded with AL2O3 particle size 150μm, Translucency was determined using a portable reflective spectrophotometer and biaxial flexure strength test with a ball on ring was conducted.Data were statistically analyzed. Results: Samples treated with 110 um particle size (group 3), recorded the highest mean translucency value, meanwhile the lowest mean value was recorded for 150 um particle size treated samples (group 4). Regarding biaxial flexural strength 150 um particle size treated samples (group 4), recorded the highest mean value, meanwhile the lowest mean value was recorded the control group. Conclusions: Air- abrasion can be done with different particle size without affecting translucency and biaxial flexural strength of Lava Ultimate. | ||||
