Description

  The present invention relates to a surgical guide for implant placement, and more particularly to a surgical guide and a sleeve-like member used therefor.

  Recently, it has become common to embed an implant (artificial tooth root) in a location where a tooth is missing and to make an artificial tooth based on the implant. When performing this type of surgery, it is necessary to first drill a hole in the artificial root in the jawbone. At that time, guide the drill landing point, angle and depth in the correct direction, Conventionally, a surgical guide is known as an instrument for preventing the above-described problem.

  The dentist first sets the surgical guide in the patient's mouth during implant surgery. Then, a drill is inserted into a sleeve-like member (metal cylindrical member) embedded in the surgical guide, and an implant insertion hole is formed in the jawbone.

  Implant surgery is a surgical guide that enables the precise placement of implant holes at the planned location, minimizing drilling failures, the greatest risk of implant treatment. is there.

  Thus, in the conventional surgical guide, as shown in FIG. 7, the sleeve-like member a is usually formed in a cylindrical shape. Then, a drill is inserted into the sleeve-like member a from above, and an embedding hole is formed in the jawbone.

  Therefore, when the conventional product is used, especially when forming the implant insertion hole in the premolars and molars, the drilling operation is difficult and the patient is forced to suffer from a large opening. In addition, conventional products cannot be used for patients who cannot open their mouths, and there is a problem that safe surgery cannot be performed.

JP 2013-102929 A

The present invention has been proposed in view of such a conventional situation.
Therefore, the technical problem to be solved by the present invention is that the insertion hole of the back teeth, that is, the premolars and molars, can be safely, reliably and easily without causing the patient to open a large mouth. Another object of the present invention is to provide a surgical guide and a sleeve-like member used for the surgical guide which can be easily opened and can be safely operated even for a patient who cannot open a mouth.

The present invention adopts the following technical means in order to solve the above problems.
That is, as shown in FIG. 1 and the like, the surgical guide 1 of the present invention includes a sleeve-like member 3 that guides a drill 2 that opens an artificial root insertion hole in the jawbone, and the sleeve-like member 3 has a shaft. A cross section in a direction orthogonal to the direction is formed in a C shape, and an opening 3a extending in the axial direction is provided facing the cheek side (Claim 1).

  In the case of the present invention, the sleeve-like member 3 is not limited to being formed in a literal C-shape. That is, the sleeve-like member 3 may be formed in, for example, a U shape or a square groove shape in accordance with the cross-sectional shape of the drill head 2a engaged with the inner peripheral surface thereof.

  Here, the axially extending opening 3a is provided facing the cheek side, that is, the drill 2 is inserted into the sleeve-like member 3 from the cheek side, in other words, from the outside of the surgical guide 1. This means that the sleeve-like member 3 is provided so that the drill 2 can be operated in the vertical direction.

  Thus, the sleeve-like member 3 used in the surgical guide 1 of the present invention is characterized in that the cross section in the direction orthogonal to the axial direction is formed in a C-shape (claim 2). .

  The sleeve-like member 3 is usually formed of a metal material or a synthetic resin material. The meaning of the C shape is as described above.

  In the surgical guide according to the present invention, the sleeve-like member is formed in a C-shaped section in a direction orthogonal to the axial direction, and an opening extending in the axial direction is provided facing the cheek side. ing.

  Therefore, since the present invention product can be operated by carrying the drill from the lateral direction of the sleeve-like member, even if the patient's opening is not sufficiently obtained, the implant insertion hole for the premolars and molars can be used. , Safe, reliable, and easy to use without causing pain to the patient, and can be performed safely even for patients who cannot open their mouths. .

  In addition, according to the sleeve-like member of the present invention, the implant insertion hole for the back teeth can be opened safely, reliably, easily, without causing pain to the patient, and even for patients who cannot open a large mouth. A surgical guide capable of performing safe implant surgery can be realized.

It is a principal part expansion perspective view of this invention product. It is principal part sectional drawing for demonstrating the use condition of this invention product in the III-III line of FIG. It is a top view which shows other embodiment of a sleeve-shaped member. It is a top view which shows other embodiment of a sleeve-shaped member. It is a top view which shows other embodiment of a sleeve-shaped member. A conventional product is shown, A is a perspective view, B is a perspective view of a sleeve-like member, and C is a plan view of the sleeve-like member.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
The surgical guide 1 of the present invention is formed with a sleeve-like member 3 that guides a drill 2 (see FIG. 3) that opens an artificial root insertion hole in a jawbone during an implant operation.

  The sleeve-shaped member 3 is formed of a metal material, and as shown in FIG. 1 and the like, a cross section in a direction orthogonal to the axial direction is formed in a C shape. In this case, the inner diameter of the sleeve-like member 3 is selected so that the inner peripheral surface engages with and slides on the outer peripheral surface of the drill head 2a.

  Further, the sleeve-like member 3 is provided so that the opening 3a extending in the axial direction is directed to the cheek side, in other words, opens in a C-shape toward the outside of the surgical guide 1.

Next, an example of using the device of the present invention will be described.
First, the dentist attaches the surgical guide 1 to the tooth surface, bone surface, and mucosal surface of the patient's upper and lower jaws. Next, a drill 2 (see FIG. 3) is inserted into the sleeve-like member 3, and an implant embedding hole is formed in the jawbone.

As described above, the surgical guide 1 of the present invention is formed in a C-shaped cross section and opens in a C-shape on the cheek side.
Therefore, in the product of the present invention, the blade 2b of the drill 2 can be inserted into the sleeve-like member 3 from the lateral direction and can be operated along the axial direction. In this case, since the drill head 2 a is engaged with the inner peripheral surface of the sleeve-like member 3, the drill head 2 a is smoothly guided by the sleeve-like member 3.

  Therefore, if the device of the present invention is used, drilling is easy even when implanting premolars and molars, and as a result, an embedding hole can be formed at an accurate position and direction as simulated.

  In the above place, in the case of the present invention, the shape of the sleeve-like member 3 is not limited to the above example. That is, the sleeve-like member 3 may be appropriately formed as shown in FIGS. 4 to 6 according to the cross-sectional shape of the drill head 2a. This is because even with these shapes, the problems of the present invention can be achieved.

  Specifically, the cross section in the direction orthogonal to the axial direction is formed in a U shape (see FIG. 4), is formed in a square groove shape (see FIG. 5), or as shown in FIG. It may be formed in a lip channel steel shape.
