Therefore, the root of the incision is the uniaxial tension state, and the maximum tensile stress is equal to the first principal stress. The theory of maximum tensile stress considers the main reason for the brittle fracture is that the maximum tensile stress reaches the ultimate tensile stress when the material is uniaxial stretched.

In all the models, the minimum principal stress (FRD: -2.025 MPa, screwed-FRD: -1.627 MPa, TFBC: -1.525 MPa, and screwed-TFBC: -1.074 MPa) in the buccal neck of the first upper molar is more active; hence, the compressive stress is observed in the buccal of the first upper molar teeth.
