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. |
