Abstract: Provided are related to implant abutments. The implant abutment that is coupled to a fixture that becomes an artificial tooth root by being implanted to an alveolar bone, the implant abutment includes: a main body; a first rotating member that is coupled to the main body to be able to rotate with respect to a first rotational axis, includes a first gear portion on an end portion thereof, and includes a male screw portion that is formed on the other end portion thereof to be screw coupled to the fixture; and a second rotating member that is coupled to the main body to be able to rotate with respect to a second rotational axis which crosses the first rotational axis, and includes a second gear portion that is formed on the other end portion thereof to form a bevel gear structure by being coupled to the first gear portion.

Abstract: A mold for producing a coping used in a dental implant includes a male component having a protrusion and a female screw forming part. The mold further includes a female component having a recess and a male screw forming part having a different rotation direction from that of the female screw forming part. A cavity for producing the coping is formed by combining the male and female components. Since the mold includes a male component having a female screw forming part, and a female component having a male screw forming part with a different rotation direction than the female screw forming part, a produced coping may be easily separated from the male and female components.

Abstract: A guide block for a dental implant procedure, a guide block assembly, and a dental implant procedural technique using the guide block, which enable a dental implant procedure to be accurately performed by allowing one or more surgical holes to be quickly and accurately bored during a boring process in which the one or more surgical holes are bored in an alveolar bone in a dental implant procedure.
