Materials and Methods: 4 pesudo-realistic models were fabricated with two remaining canines as abutments. One canine was treated with lateral obturation technique and the other with vertical obturation. An over-denture was fabricated on the model. Then strain gauges were attached on the coronal one third of the root buccally and lingually. 50 N were applied on the middle of the model using universal testing machine and readings were collected. Results: From the collected data the lateral obturation showed 85.25±104.901 μ∈ and the vertical obturation showed 4.875±3.555 μ∈ with significance difference of P<0.05 between the groups. Conclusion: It can be concluded that the abutments treated with vertical obturation techniques reduced the stresses induced to the supporting structures when compared with the lateral condensation technique. © 2021 University Library System, University of Pittsburgh.
