Effect of Thermodynamic Cyclic Loading on Screw Loosening of Tightened Versus New Abutment Screw in Bone Level and Tissue Level Implants in DIO Implant Company (In‐Vitro Study)

Clinical and Experimental Dental Research, Volume 11, Issue 4, August 2025.
ABSTRACT Objectives The loosening of abutment screws is a common mechanical complication in dental implants, potentially leading to treatment failure. It is generally believed that dynamic forces may accelerate and facilitate screw loosening. Two approaches exist to address this issue: replacing the screw or re‐tightening the existing one.
