Abstract
In order to determine how various materials and abutment connections react to the retightening effect of the abutment screw when saliva or blood enters the space between the abutment and the dental implant, this study used finite element techniques. Dental implant systems are created with polyether ether ketone-reinforced carbon utilizing a random sequential algorithm (RSA) that is modelled in ANSYS to understand the impact of internal-hex and conical abutment types. The abutment screw is tightened (stage 1), relaxed (stage 2), retightened (stage 3), and then relaxed (stage 4) to determine the preload value and removal torque. Internal hexagonal abutment connections and CFR-PEEK composite materials have been shown to be exceptionally good at preventing screw loosening. It is discovered that a conical connection is a poor abutment for preventing screw loosening.
