Abstract:
1. A surgical guide used for performing three dimensional positioning of a drill when a guide hole into which a dental implant fixture is to be embedded is formed in an alveolar bone in the mouth by the drill, the surgical guide comprising: an optical irradiation apparatus having at least two optical irradiating portions each configured to irradiate a plane-shaped light beam from a direction different from each other and toward a position corresponding to a position in which a wire is embeddable in a mockup that imitates an inside of the mouth of a patient, an adjusting mechanism that supports the two optical irradiating portions movably forward, backward, rightward, leftward, upward, or downward, and rotatably, and a detachably attachable guide member that supports the adjusting mechanism and is configured to position the adjusting mechanism when the guide member is fitted to a tooth portion of the mockup or to an actual tooth portion of the patient that corresponds to the tooth portion of the mockup, wherein, when the guide member is fitted to the tooth portion of the mockup, the adjusting mechanism is configured to adjust the optical irradiating portions such that the two plane-shaped light beams linearly intersect at the position corresponding to the position in which the wire is embeddable in the mock up, wherein the guide member is configured to be removed from the mockup and fitted to the actual tooth portion of the patient, and wherein the guide member is configured to allow a hole to be formed by the drill while the drill is aligned with the position at which the two plane-shaped light beams linearly intersect.
