In this research, a computer with integrated software connected to a Computer Numerical Control (CNC) milling machine was used to machine presintered Aconia zirconia samples as per the ASTMC1161-13 standard. The aim was to improve the surface characteristics and mechanical properties of presintered zirconia ceramic by varying cutting conditions such as depth of cut (0.1, 0.3, and 0.5 mm), rotational speed (6000, 9000, and 12000 rpm), and tool diameter (1.5 and 2.5 mm). Before sintering, using a bur diameter of 2.5 mm yielded the lowest roughness value of 0.76 µm at 9000 rpm with a depth of 0.1 mm. The surface roughness decreased as the cutting speed increased and cutting depth decreased. After sintering at 1500℃ for 2 hours at a rate of 8℃/min, the maximum hardness value of 1458.73 HV was obtained at 6000 rpm using a bur diameter of 2.5 mm. The highest flexural strength value of 566.67 MPa was obtained at a rotational speed of 6000 rpm, depth of cut of 0.1 mm, and tool diameter of 1.5 mm. The highest surface fracture toughness value of 414.94 MPa/mm 2 was obtained at a rotational speed of 12000 rpm, depth of cut of 0.5 mm, and tool diameter of 2.5 mm. Additionally, the use of high cutting speed during the milling processes reduced the mechanical properties of the Aconia zirconia, such as flexural strength and microhardness, when using a tool diameter of 1.5 mm. However, these mechanical properties increased when using a tool diameter of

Removable complete dentures are still a therapy of choice for a variety of medical professionals and patients even in an era of implant and fix prostheses. This article focuses on comparing complete dentures manufactured using various denture base materials. Heat-cured polymethylmethacrylate, used for prosthetic complete denture composites, was blended separately with Polyamide (PA) type 6 and Polyvinylpyrrolidone (PVP) type K30. These blends were prepared with various weight fractions (0%, 2%, 4%, and 6%) and reinforced with sisal and coconut powders, each added individually with varying weight fractions (2%, 4%, and 6%). The tensile test was carried out to achieve tensile strength, modulus of elasticity, and elongation percentage values. The numerical part depends on the Finite Element Method (FEM), conducted by using Ansys Workbench-2020 R2. According to the experimental data, the tensile strength, elastic modulus, and elongation of polymer blends increase at a 2% weight fraction of PA and PVP particles, and then decrease with higher PA and PVP particles' weight fraction. However, they decrease with increasing weight fraction of coconut and sisal particles. The highest tensile strength and elastic modulus are 86 MPa and 2.531 GPa, respectively, for PMMA-2% PA, and the greatest elongation percentage is 5.28% for PMMA-2% PVP. These findings lead to the conclusion that the addition of polymer blend materials to PMMA resin is a promising approach for improving tensile properties in applications such as complete or partial denture bases, addressing an ongoing challenge
