- Abstract
Introduction: Several types of implants are available on the market, including internal or external hexagonal connections and the Morse Taper connection. The latter provides better distribution and transmission of forces throughout the implant. Implant osseointegration can be measured and assessed by reverse torque. Objective: The objective of this study is to test, in Morse Taper implants installed in rabbits' tibia, the feasibility of a new reverse torque assessment method. Methods: Neodent Morse Taper WS implants were installed in rabbits' tibia. The animals were sacrificed at different periods of time. The bone blocks containing the implants were cut, and a corresponding mounting device was attached to the implant, forming a single pillar. Reverse torque was simulated using a universal testing machine EMIC DL 1000. Compressive force was applied to the arm of the ratchet. Results: The values obtained with the test were: Rabbit 1 (immediate) = 1.8 Kgf, Rabbit 2 (7 days) = 7.6 Kgf, Rabbit 3 (15 days) = 17 Kgf, Rabbit 4 (30 days)=27Kgf, and Rabbit 5 (45 days) = 36 Kgf. Conclusion: Results were promising as they indicated an increase in the value of reverse torque over time.
