The Construction of Finite Element Model of Invisible Appliance of Inhomogeneous Thickness by Reverse Engineering Technology

Abstract:

Reverse engineering technology and Laser scanning technology was used to obtain and establish the ideal digital dental mode and dental model with invisible appliance. To complete the Boolean subtraction between the dental model with invisible appliance and the ideal dental mode by the alignment marks designed in the guml, so that got the digital model of invisible appliance. Then the finite element model was established by the finite element analysis platform ANSYS. A more precise dentition finite element model of invisible appliance is established, which can reflect the real surface geometrical morphology of invisible appliance and its inhomogeneous thickness characteristics.
