Objective: Evaluate the biomechanical behavior of three implant brands with different surfaces by comparing stability parameters during placement and removal. Materials and Methods: An experimental study was conducted with 8 rabbits, in which 21 implants from three different brands were placed: ML Implant System®, Roster Dent®, and Biomet 3i® Osseotite. Seven implants of each brand were placed in each femur, and resonance frequency analysis was performed to measure the initial stability coefficient (initial ISQ). At 60 days, the final stability coefficient of the implants was measured. To measure removal torque, the implants were fixed in a press, and a Mark-10 precision digital torque wrench was used. Implants were removed by reverse rotation, recording the peak removal torque value. Results: Regarding initial-stage stability, the Roster Dent® and ML Implant System® groups showed h...
