Abstract
A screw for dental implants, used to fix dental prostheses to abutments combined with fixtures previously inserted in the alveolar bone, includes a screw portion and a screw-head portion. The screw-head portion includes a guide consisting of a pair of inclined planes and a tool-receiver, formed between the inclined planes along a center line crossing an upper face of the screw, for transmitting working torque exerted by a tool. A screw set for dental implants includes a plurality of dental-implant screws, each having a screw portion and a screw-head portion of varying height, and each screw-head portion includes the same combination of guide and tool-receiver. The improved screw facilitates tightening and untightening of the screw.
