Abstract: A surgical guide used in implant treatment. A wire is mounted to a mockup at the orientation at which an implant fixture should be embedded. A guide member of a surgical guide is fitted to a tooth portion of the mockup. The optical axis of an irradiated light beam guided by a light irradiation portion from a light emitting portion through an optical fiber is aligned with the central axis of the wire by moving and adjusting the portion supported by a wire member. Drilling is performed after the adjusted guide member is removed from the mockup and fitted to a patient's tooth portion and the central axis of a drill is aligned with the optical axis of the beam.

Abstract: Provided is a drilling device having a simple configuration, and being less likely to cause errors in drilling direction even when the bone density of the cancellous bone to be drilled is non-uniform. A drilling device includes a drill having a central hole formed from a front end along a rotation axis, and a guide pin inserted in the central hole from the front end, wherein the drilling direction thereof is determined by a guide pin embedded either in an embedding hole formed by a pilot hole drilling device or an embedding hole formed by a drill in one previous step.

Abstract: Provided is a surgical guide that enables a dentist to visually identify the tip of a drill during dental implant treatment, and does not allow the drill to tilt more than necessary, and enables sufficient cooling water to be provided so as not to cause bone burns, and is compatible with several different types of drills having different diameters. A first wire is embedded in a mockup in a same orientation as the orientation of a fixture of an implant is to be embedded. A guide member of a surgical guide is fitted to a tooth portion of the mockup. An adjusting mechanism adjusts such that an intersection line made by plane-shaped red laser light beam and green laser light beam from line laser modules is located on the first wire. The guide member is removed from the tooth portion of the mockup, and fitted to a tooth portion in the mouth, and the orientation of a drill is aligned with the intersection line. Drilling operation is performed in the aligned condition.

Abstract: Provided is a stent used when a wire that indicates the position and orientation a fixture is to be embedded at on a mockup for creating an anatomically and prosthetically appropriate and highly accurate surgical guide. The stent includes a detachably attachable guide member 1 that includes a fitting portion 2 to be fitted to a tooth portion of the mockup and an actual tooth portion of a patient corresponding to the tooth portion of the mockup, and a covering portion 3 covering a mucosa surface 44 at the portion a tooth is missing; a first positioning member 10 including at least a planar first contrast medium 11 for CT scanner and mounted to the covering portion 3; and a second positioning member 20 including at least a planar second contrast medium 21, the member 20 opposing to the first contrast medium 11 and detachably attachable to the member 10.

Abstract: Provided is a surgical guide used in implant treatment, with which the tip of a drill can be observed and cooling water can be sufficiently provided not to cause bone burns, and which will not allow the drill to tilt more than necessary and is compatible with drills having different diameters. A wire 31 is mounted to a mockup 30 at the orientation an implant fixture should be embedded at. A guide member 11 of a surgical guide 10 is fitted to a tooth portion of the mockup 30. The optical axis of an irradiated light beam L guided by a light irradiation portion 16 from a light emitting portion 14 through an optical fiber 15 is aligned with the central axis of the wire 31 by moving and adjusting the portion 16 supported by a wire member 12. Drilling is performed after the adjusted guide member 11 is removed from the mockup 30 and fitted to a patient's tooth portion and the central axis of a drill 41 is aligned with the optical axis of the beam L.
