Abstract

Conventionally dental crown manufacturing was done by investment casting. This work presents the Rapid Prototyping as a best tool for dental prosthesis and crown manufacturing. It also represents the static structural analysis of dental crown with FEM software, ANSYS 14.5. Crown Models are constructed with dental wings client software and mimics . FEM compatible models were constructed using Remeshing and Volume meshing tool of 3-matic software. Masticatory force 350 N was applied downward perpendicular to surface of molar crown with boundary conditions. Five materials such as Ti-6Al-4V, Stainless steel, Cobalt-Chromium, Zirconia and Titanium are selected for analysis. Zirconia and Cobalt-Chromium are found to be the best materials amongst the five. ANSYS results show that the optimum crown thickness ranges from 1.75 to 2.25 mm. Directional deformation is very less for the crown model developed with dental wings. Tooth preparation is the main parameter which affects the strength of crown 3D printing is the most promising tool for Dental Prosthesis manufacturing. It can be manufactured with selective laser sintering, ink-jet printing. This model is manufactured with Desktop CNC milling in Cobalt-Chromium metal.
