چکیده :

This study aimed to develop a connecting dental implant with a micro-motor mechanism that simulates the oral ligament’s biomechanical behavior to increase dental implants’ lifespan. A computer design software was used to design a connecting dental implant with a flexible internal component and micro-movement capability. The feasibility of the new system was investigated by finite element analysis. Then a prototype of the attached dental implant was made, and its mechanical behavior was evaluated. The mechanical tests and finite element analysis results confirm that the new connecting dental implant can predict micro-motion. In addition to the evident and nonlinear displacement behavior in this micro-motor mechanism, it simulates a natural tooth’s movement in the human body. The slope of this new implant’s force-displacement curve is about 38.5 N/mm before the 0.02 mm displacement and about 430 N/mm after the 0.03 mm displacement. This new dental implant with a micro-movement mechanism simulates and imitates a natural tooth’s biomechanical behavior and has elastic, micro-movement, non-detachable, and easy-to-use function.
