Objective . To evaluate the influence of screw‐tightening methods on immediate and long‐term stability dental implant screw joints. Methodology A total 150 implants three different systems with diameters were used in this study. Each group was divided into subgroups ( n = 5), according to tightening (A—tightening recommended torque retorque after 10 min; B—tightening torque, then loosening retorque; C—tightening only once). The operating time assemblies recorded. Ten minutes later, removal...
