Abstract :
Post fiber, core, and crown restorations in
post-endodontic treatment using ferrules strengthen teeth
after post-restoration. To investigate the effect of
different ferrule height designs on the resistance of dental
fractures following endodontic treatment, using
AUTOCAD as the basis for non-linear finite element
analysis. Five models of 3D maxillary first incisors were
constructed using AutoCAD 2016 with five different
ferrule heights (mm) 0, 0.5, 1, 1.5, and 2, meshing and
input mechanical properties, followed by loading 25 N
and 170 N at an angle of 135° in the tooth palatal area
which was analyzed by Finite element analysis (FEA)
using ANSYS v 17.0 software. Von Mises analysis shows
the maximum and minimum deformation values,
equivalent elastic strain, and equivalent stress. The
ferrule's total deformation value in the 25 N simulation
was the highest at 0 mm (0.0093 mm) and the lowest at 2
mm (0.0091 mm). The simulation load was 170 N, the
highest at 0 mm (0.0632 mm) and the lowest at 2 mm
(0.0618 mm). The maximum equivalent elastic strain
value of ferulle is highest at 1 mm (0.034814 mm) and
lowest at 0 mm (0.03245 mm). The maximum equal stress
value decreases in models with ferrules. In the 25 N and
170 N simulations, the highest values on the 3D model are
at 0 mm (13,008 MPa and 88,452 MPa) and the lowest at
1 mm (11,567 MPa and 78,655 MPa). Conclusion.The
addition of ferrule height can increase dental fractures'
resistance after endodontic treatment by reducing
deformation. Ferrule decreases stress on the tooth's labial
cervical area and enlarges the strain on the cervical
palatal dentine by holding non-axial loads from the
palatal side
