Description

Implant Procedure Guide Device

The present invention relates to an implant guide device, and more particularly to an implant guide device having a shape in which the side of the guide hole is opened to the gingival portion for improving the convenience of the procedure.

Implant is a prosthesis used to replace a badly damaged tooth. An artificial root made of a special metal (usually titanium or titanium alloy) is implanted in the alveolar bone and entangled with the alveolar bone tissue. By using the artificial tooth to form a dental treatment method that allows you to live daily life with a sense almost the same as the original one of their own teeth or the artificial tooth itself as described above.

These implants have recently gained much attention as they have advantages such as long life and very similar to natural teeth, without damaging the surrounding teeth except for the teeth that need to be treated, compared to the methods using dentures and bridges. .

Briefly describing the method of implantation, the alveolar bone is exposed by first dissecting the gingiva (gum) of the patient to be implanted. Next, the position of the implant to be inserted among the exposed alveolar bone is determined, and a hole for implantation is formed by deleting a portion of the alveolar bone using a drilling tool such as a drill device at the position. Thereafter, an implant including a fixture and an abutment is placed in the formed hole, and the implant installation is completed by covering the gingival part.

In general, when implanting the gingival portion to expose the alveolar bone during the implantation procedure and then drill directly using the drill, it is difficult to pinpoint the exact position and direction to perform the drilling operation, so it is usually a separate surgical guide device Will be used.

However, in the case of the conventional surgical guide device because the side portion is not open because of the height of the guide hole protruding vertically, it is impossible to enter the surgical drill device when the distance between the jaw is not sufficient, such as the posterior part. exist.

As shown in Figure 1 and 2, the implant guide device according to an embodiment of the present invention may include a support 100, a guide member 110 and the opening 112a.

Support 100 may be formed to surround the buccal, lingual and occlusal of the tooth. The support 100 may be manufactured by heating a transparent thermoplastic resin by an omni bag. Here, the material of the support 100 may be formed of not only a transparent resin, but also fiber reinforced plastics or carbon fibers. As the reinforcing material of the fiber reinforced plastic, glass fiber, carbon fiber or Kevlar may be used.

In addition, a separate fastening member 120 may be penetrated through a position adjacent to the perforation part 1 of the support 100 so that the support 100 may be firmly fixed to the gingiva. Although not specifically illustrated in the present embodiment, the fastening member 120 may pass through the support 100 and the end of the fastening member 120 may be coupled by penetrating the gingiva 1a and the alveolar bone. At this time, the end of the fastening member 120 may be screwed to the gingiva and alveolar bone by forming a thread on a portion of the outer peripheral surface.

In this embodiment, the support 100 is shown in a shape formed to cover the entire lower jaw, the support 100 may be formed to cover the entire maxillary or part, or the entire lower jaw or part, depending on the number or position of the dental prosthesis placement. It may be so limited. In other words, the support 100 may be formed so as to surround only some of the corresponding teeth in case some of the teeth are lost in addition to the shape surrounding the entire teeth.

In addition, although the shape in which the guide member 110 is formed at the molar portion at the lower jaw is shown, when the position where the dental prosthesis is required to be placed is an anterior region, the support 100 is lip-sided. It may be formed to cover a labial surface, a lingual surface, which is a facing surface, and a proximal surface or a contact surface, which is a surface where two teeth meet. .

In addition, when the dental prosthesis is to be placed in the posterior region, the support 100 has a buccal surface that is a face toward the cheek, a lingual surface that is a face toward the tongue, and It may be formed so as to cover a contact surface that is a surface where the two teeth abut. The contact surface may mean an occlusal surface or a mastication surface when the teeth (upper teeth-lower teeth) facing each other when closing the mouth are in contact with each other.

The guide member 110 may include a guide hole 112 protruding from the support 100, protruding from the occlusal surface, and having a circular cross section. At this time, when the support member 100 is installed in the upper jaw, the guide member 110 may protrude downward, or when the support member 100 is installed in the lower jaw, the guide member 110 may protrude upward. have.

In addition, at least one guide hole 112 may be formed according to the number of holes to be implanted. That is, the guide holes 112 may be formed in plural to be disposed coaxially with the puncturing portion 1 of the alveolar bone. As described above, when a plurality of guide holes 112 are formed, the guide holes 112 may be disposed to correspond to the respective perforation sites 1, and the lingual sides of the plurality of guide holes 112 may be integrally connected along the teeth. Can be.

In addition, the guide hole 112 may be in contact with the outer circumferential surface of the drill head 11 to support the rotation of the punching member 12 while the outer circumferential surface of the drill head 11 of the drill apparatus 10 is in surface contact. It can be formed to have an inner diameter.

In this case, as shown in FIG. 2, the cross-sectional shape of the guide hole 112 corresponds to the cross-sectional shape of the drill head 11 such that the inner circumferential surface of the guide hole 112 contacts the outer circumferential surface of the drill head 11. The inner diameter D1 of the 112 is formed to be larger than the inner separation distance D2 of the opening 112a of the guide member 110, so that the drill head 11 is drilled in the state in contact with the inner circumferential surface of the guide hole 112. The vibration of the device 10 ensures that the perforated member 12 is firmly held away from the perforated region 1. That is, the center of the cylinder of the guide hole 112 is disposed coaxially with the center of the cylinder of the drill head 11, and the separation distance of the open width of the opening 112a opened in a direction away from the center is a guide hole ( It may be formed smaller than the diameter of (112).

In addition, the inner diameter of the guide hole 112 is larger than the inner diameter of the drilled portion 1 of the alveolar bone because the inner diameter of the guide hole 112 is formed to be the same as or larger than the outer diameter of the drill head 11 having a larger diameter than the drilling member 12 of the drill apparatus 10. Of course it is formed.

On the other hand, the opening 112a is cut so that the narrow surface side of the guide member 110 is exposed, but the pair of open ends 112b of the opening 112a have a rotation center C along the longitudinal direction of the guide hole 112. ) And the angle R may be formed at approximately 110 ° to 140 °. Here, the angle R is the minimum angle that can support the outer circumferential surface of the drill head 11 so as not to be separated through the opening 112a and the minimum angle that the user of the drill apparatus can visually check the entire drilled portion 1 visually. It can be set within a range. Preferably, the angle R may be set to 120 degrees to 130 degrees.

The opening 112a may be cut to a size such that a part of the narrow side of the guide member 110 is exposed so that the user can secure a view of the perforation part 1 through the opening 112a. In addition, since the drilling member 12 of the drill device 10 is movable through the opening 112a in the process of moving to position the drilling portion 1, interference by the guide member 110 may be prevented. .

In addition, the opening portion 112a further includes a gingival opening portion 100a which is extended from the opening portion 112a to further expose the narrow side of the support 100 so that a portion of the gingiva 1a is cut out to be exposed to the outside. can do. The gingiva opening 100a extends in the direction of the gingiva from the opening 112a, and is gingival even if the user looks at a position lower than the end of the guide member 110 regardless of the position and distance of the patient. Visually confirming the gingival portion 1a through the opening portion 100a enables the operation.

Figure 3 is a perspective view of the implant guide device according to another embodiment of the present invention. As shown in FIG. 3, the implant guide device according to another embodiment of the present invention may further include a connection bar 130 connected across the gingiva opening 100a of the support 100.

When comparing the configuration of FIG. 3 with the configuration of FIG. 1, the connecting bar 130 is formed across the gingiva opening 100a of the support 100, and the ends of the gingiva opening 100a are connected to each other. There is a difference in that, since the other configurations are the same, overlapping description is omitted.

Since the gingiva opening 100a extends from the opening 112a of the guide member 110 and is cut away, durability of the gingiva 100a is prevented from being lowered compared to the structure in which the support 100 is installed to cover the entire gingiva. Connection bar 130 may be formed in order to. In addition, a separate fastening member 140 penetrates and couples to the connection bar 130, and the fastening member 140 penetrates the gingiva 1a and the alveolar bone, thereby ensuring higher durability. In this case, the connection bar 130 may be formed integrally with the support 100 or may be separately coupled to the support 100 by separate fastening protrusions (not shown) or fastening grooves (not shown) at both ends of the connection bar 130. It can be formed to.

As such, since the fastening member 140 may be coupled at a position close to the perforation part 1, it may have an advantage in terms of securing durability.

As described above, the implant guide device according to the embodiment of the present invention improves the convenience of the procedure through securing the field of view when entering the drill device by opening the side of the guide member to the gingival portion, and openings 112a during the drill operation. And through the gingiva opening (100a) can be made smooth smooth water can also improve the safety of the procedure. In addition, it is possible to give the operator a sense of security through securing the field of view to be drilled in the alveolar bone, including the gingival.
