Aims and objectives: The study was conducted to evaluate the biomechanical response of the bone, for the comparison of single vs double implants replacing the mandibular first molar via a three-dimensional finite element analysis (FEA). Materials and methods: Three-dimensional FEA model was generated to compare the induced displacements and stresses as a result of various loading conditions on a mandibular first molar crown supported by a regular 4.2-mm–diameter implant and two 3.5 mm–diameter implants. For each implant design, the loading process 70 N, on three locations (vertical to the long axis) was done and generated von Mises equivalent stress, and resultant displacements were recorded. Results: For single implant design, the von Mises stress was found to be 173.61 MPa at the distobuccal cusp tip, whereas for Double-implants (3.5 mm-implants), the maximum stress of 145.12 MPa was found at the distobuccal cusp tip. Conclusion: The use of double-diameter implants may be mechanically advantageous in restoring single molars, as they enhance the mechanical properties of the implant system through the increased surface area, stronger resistance to component fracture, increased abutment stability, and enhanced emergence profile.
