Objective: To evaluate the influence of the coating material on the dental implant abutment screw stability and to analyze the relationship between preload and opening torque.

The effects of the bearing eccentricity and the pads preload on the bearing load capacity,minimum gas-film thickness,maximum gas-film pressure and pads tilting angle were investigated.

The effect of preload does not be considered in an analytical model of the ball screw at other research.
