Titanium tends to seizure with other metals, so titanium unfits thread rolling for dental implant with φ3mm diameter or less. Therefore we lubricate the contact point and prevent the seizure by applying a textured surface on the die. We were examined for the textured surface for reducing the shear stress by plastically deformed analysis between titanium material and die, and fluid analysis of the oil around the textured surface. From this analysis, texture provides an effective of low-friction, and a dimple type texture reduces shear stress by 28%.
