Paper presents the detail study and results of the experimental investigation during fabrication of artificial teeth. In present study, explained the fabrication processes of artificial teeth prosthesis which includes design to establish geometry in orthocad software, selection of material and machining of artificial teeth. The Poly Methyl Methacrylate (PMMA) material is selected for artificial teeth because of its good modulus of elasticity, corrosion resistance, hardness and biocompatibility. Machining is done on CNC milling machine with glass ceramic tools. The machining of artificial teeth is very challenging due to the complex shape of teeth and the associated restrictive geometrical and dimensional requirements. To achieve the required surface finish, the input cutting parameters is optimized based on Taguchi design of experiment. In this study various machining challenges are described during machining of PMMA. The SEM images of artificial teeth were taken and analysed the surface texture of the fabricated teeth. The surface roughness heights, Ra (µm) and Rt (µm) of fabricated artificial teeth were measured and analysed in the paper.
