Abstract
The aim of this in-vitro study was to evaluate the influence of different build
angles on the fracture resistance of implant retained, 3D- printed overdentures fabricated
with two different build angles will be used and compared in this study; a 1000
and a
1500
build angle.
Methodology: A ready-made resin full edentulous mandibular model will be used with
two implant inserted in interforaminal region. Optical scanning for the model with
implant was done in order to construct standard tessellation language (STL) file and
design an implant overdenture. Then 3D printing will be done using digital light
processing (DLP) printer with two different build angle(1000
and 1500
).The fracture
resistance will be measured in two groups; by applying vertical forces at different
points(one at anterior region and two at first molar region bilaterally) in the first group
with overdentures printed with a 1000
build angle while in the second group the
overdentures which fabricated with a 1500
build angle using Universal testing machine
after being subjected to cycling load for 240000 cycle in chewing simulator machine.
Results: There was no statistically significant difference between fracture resistance
values of 100º and 150º build angles.
