Description

Multiple implant placement guide device

[0001] The present invention relates to a technology for a multi-implant placement guide device that guides the drilling position and drilling angle to enable accurate implant placement during implant surgery for an edentulous jaw patient.

[0002] More specifically, the present invention relates to a multi-implant placement guide device that increases the degree of freedom in setting the drilling position and angle performed by a surgeon during a drilling procedure while easily guiding the entry direction and position of a drill bit to maintain a certain level of drilling operation results.

[0003] In addition, it is a technology that improves the drilling convenience of the operator by providing a structure that can easily guide the direction and position of the drill bit during the operator's drilling work.

[0004] In the case of edentulous patients who have lost most of their teeth or have no teeth left, full-arch implants are performed. Full-arch implants are a surgical method that reconstructs the entire set of teeth using multiple structures by implanting 6 to 10 implants each in the upper and lower jaws, which require strong chewing force, rather than implanting artificial teeth one by one, and then connecting dental prostheses for the remaining parts.

[0005] However, full-arch implants are only possible when there is sufficient gum bone to place the implants, and the number of implants to be placed is large, and the procedure takes a lot of time, so the procedure cost is high.

[0006] Recently, unlike the existing full-arch implant, a digital full-arch technology has been applied that implements the function of all teeth with only 4 to 6 implants. The digital full-arch is a method of fixing a full-arch type prosthesis in which 12 artificial teeth are connected as a whole after 4 to 6 implants are placed, as shown in Figure 1.

[0007] Digital full arch is also called all on 4, all on 5, and all on 6 depending on the number of implants placed.

[0008] This digital full-arch technique offers numerous advantages, including the minimal number of implants required. However, for a successful outcome, precise placement of the minimal number of implants at the correct angle and location is paramount. This is especially true for edentulous patients, who often have significant alveolar bone loss and receding, requiring even more precise treatment due to the narrow depth of the nerves that pass from the gums to the jawbone.

[0009] Accordingly, a product as shown in Fig. 2 is used as a guide device that guides the implant placement position and angle during implant surgery for edentulous patients. Fig. 2 (a) shows the structure of such a conventional guide device, in which a fixing pin is attached to the center of a steel plate, and vertical guide lines and inclined guide lines are marked at regular intervals in the horizontal direction on the steel plate.

[0010] And during the procedure, the two wings of the steel plate are bent along the dental arch, and the drilling operation is performed while maintaining a certain inclination angle so that the nerves located in the turned bone can be avoided and a hole for implant placement can be made, as shown in Fig. 2 (b).

[0011] FIG. 3 shows a process of using the guide device of the prior art during edentulous implant surgery, in which (a) is a step of drilling a hole for inserting a central fixation pin, (b) is a step of bending the plate of the guide device along the arch while inserting and mounting the central fixation pin of the guide device into the drilled area, and (c) is a step of setting the drilling entry position and angle based on the scale indicated on the positioning plate of the guide device and drilling.

[0012] First, as shown in Fig. 3 (a), the gums of an edentulous patient are incised to expose the gum bone, and then a drilling operation is performed on the gum bone at the center of the anterior region of the lower jaw arch using a drill member (20) and a drill tool (not shown in the drawing). Here, the drill member is typically a drill bit.

[0013] Then, as shown in Fig. 3 (b), the fixing pin (40) of the guide device is inserted into the hole formed by the drill member (20) to determine the position, and then the metal plate (30) of the guide device is bent along the arch of the lower jaw.

[0014] Here, the plate (30) is made of a thin metal material that can be flexibly bent to correspond to the arch of the gums (10) as shown in Fig. 3 (b) according to the manipulation of the user (surgeon).

[0015] After the guide device is installed in the gum bone, the drilling position is determined based on the scale formed on the plate surface of the guide device as shown in Fig. 3 (c), and then the drilling operation is performed using the drill member (20).

[0016] And, after the drilling work is completed, an implant for fixing the full arch is placed in the drilled hole, and then the process of fixing the full arch is performed, but a detailed description of this will be omitted.

[0017] However, when a driller performs a drilling operation using a conventional guide device like this, the driller can only receive assistance to determine the drilling position based on the scale indicated on the plate of the conventional guide device or to determine the drilling angle based on the angle line indicated on the plate, and there is a problem in that the maintenance of the drill entry angle during the actual drilling process is entirely dependent on the skill of the driller.

[0018] In other words, the problem with conventional guide devices is that they only provide the surgeon with a rough drilling position and angle, and the maintenance of the exact position or angle is entirely dependent on the surgeon's surgical skills.

[0019] Prior art literature

[0020] Patent Registration No. 10-1675500 (Announcement date: November 11, 2016)

[0021] The present invention has been conceived to overcome the problems of the prior art, and the purpose of the present invention is to provide a multi-implant placement guide device that can ensure that a stable drilling procedure of a certain level or higher is always performed regardless of the surgical ability and skill of the surgeon.

[0022] In order to achieve the above object, a multi-implant placement guide device according to the present invention may be configured to include a plate member formed in a thin plate type so as to be bendable in response to a dental arch; a positioning member positioned at a portion protruding downward from the center of the plate member and formed so as to be insertable into the center of the gum, thereby guiding the center of the plate member; and one or more drilling guide members mounted on the front of the plate member and used for drilling operations to guide a drilling operation by holding the drill member.

[0023] In addition, the drilling guide member can be configured to slide and rotate according to the user's operation while mounted on the plate member.

[0024] Additionally, the drilling guide member includes a semicircular groove formed openly on the front surface of the body of the drilling guide member, and the semicircular groove can be configured to correspond to the shape of the outer surface of the drill member during drilling.

[0025] In addition, the method includes including a movable fixing member facing the drilling guide member with the plate member interposed therebetween, and the movable fixing member can switch between fixing and releasing the drilling guide member by operating in a fixing direction or operating in a releasing direction.

[0026] And, the moving fixing member can be screwed to the rear of the drilling guide member through the sliding slit portion of the plate member.

[0027] On the other hand, the plate member has one or more sliding slit portions cut lengthwise along the length of the body; wherein the movable fixing member can be configured to enable the drilling guide member to move and rotate along the sliding slit portions or to remain fixed according to a user's operation.

[0028] The multi-implant placement guide device of the present invention has one or more drilling guide members along the longitudinal direction of a plate member capable of bending in response to the arch of the jaw, thereby increasing the degree of freedom in setting the position and angle of drilling performed by the operator during drilling, while easily guiding the entry direction and position of the drill bit, thereby providing an effect of providing a certain level of drilling work result.

[0029] In addition, the present invention has the effect of improving the convenience of the operator during the procedure by easily switching between fixing and releasing the drilling guide member by the movable fixing member.

[0037] FIG. 8 is a perspective view of a multiple implant placement guide device according to an embodiment of the present invention viewed from another angle.

[0038] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0039] FIG. 4 is a front view illustrating a multiple implant placement guide device according to an embodiment of the present invention, and FIGS. 5, 6, 7, and 8 are perspective views of the multiple implant placement guide device according to an embodiment of the present invention viewed from various angles.

[0040] Referring to FIGS. 4 to 8, a multiple implant placement guide device according to the present invention may be configured to include a plate member (110), a positioning member (120), a drilling guide member (130), and a movement fixing member (140).

[0041] The plate member (110) may preferably be formed as a thin plate type so that it can be bent by the operator's manipulation in accordance with the shape of the dental arch.

[0042] The plate member (110) may have one or more sliding slit portions (111) formed long in the central portion thereof along the length of the body.

[0043] The sliding slit portion (111) may preferably be formed symmetrically in one or more directions from the center of the plate member (110).

[0044] In addition, a plurality of drilling guide members (130) arranged to be able to move along the longitudinal direction of the sliding slit portion (111) may be provided for each sliding slit portion (111) as in FIG. 4, or one may be provided for each sliding slit portion (111) as in FIG. 5.

[0045] The above positioning member (120) can be formed in a downward protruding extension from the central portion of the plate member (110).

[0046] At this time, it is preferable that the downward protruding extension of the plate member (110) is formed integrally with the main body of the plate member (110) by a blanking or punching process using a thin metal plate, preferably a thin stainless steel plate, and the positioning member (120) has a separately processed cylindrical body and preferably has a groove formed on the upper portion into which the downward protruding extension of the plate member (110) can be inserted or a slit groove into which the extension can be inserted. In addition, the plate member (110) and the positioning member (120) may be joined by welding.

[0047] The positioning member (120) is inserted into a hole drilled in the center of the anterior portion of the gum (10) by pilot drilling as shown in Fig. 3 (a), so that the center of the plate member (110) is positioned as shown in Fig. 3 (b).

[0048] In addition, the plate member (110) of the multi-implant placement guide device according to the present invention has sliding slit portions (111) formed on both sides with the positioning member (120) as the center.

[0049] And, a drilling guide member (130) can be inserted into this sliding slit portion (110). As in FIG. 4, a plurality of drilling guide members (130) may be provided for each sliding slit portion (111), or as in FIG. 5, one drilling guide member (130) may be provided for each sliding slit portion (111).

[0050] In addition, the drilling guide member (130) is preferably mounted on the front of the plate member (110) and is provided so that a drill member (20) used when performing a drilling operation as shown in FIG. 2 can be placed thereon, thereby guiding drilling operations so that even a driller with a relatively low level of skill can easily perform drilling operations.

[0051] Meanwhile, the drilling guide member (130) can be configured to rotate in place according to the user's operation while mounted on the plate member (110) and to slide along the sliding slit portion (110).

[0052] In addition, a guideline for guiding the angle of drilling can be formed on the front surface of the plate member (110) as in FIGS. 4 and 5, and the driller can set the drilling angle and position intended by the driller by rotating or sliding the drilling guide member (130) with reference to the guideline formed on the front surface of the plate member (110).

[0053] After the drilling guide member (130) is rotated to set an angle and slid to a certain position, the drilling guide member (130) is fixed using a movable fixing member (140) to maintain that state.

[0054] In addition, the drilling guide member (130) may preferably have a semicircular groove formed open on the front side of the body of the drilling guide member (130), and such a groove corresponds to the shape of the outer surface of the drill member (20) used during drilling work.

[0055] As a result, when the operator performs drilling work using the drill member (20) as shown in (c) of Fig. 3, the operator's convenience in working can be significantly improved by allowing the drill member (20) to be placed on the drilling guide member (130). In particular, the oral cavity where the work is performed does not provide sufficient space for smooth work no matter how much the patient opens the upper and lower jaws. Therefore, if the front of the drilling guide member (130) is made semicircular and opened to form a groove where the outer surface of the drill comes into contact, the operator can perform the drilling work very easily.

[0056] In addition, the movement fixing member (140) is an element that faces the drilling guide member (130) with the plate member (110) in between, and switches between fixing and releasing the drilling guide member (130) by operating the movement fixing member (140) in a fixing direction or operating it in a releasing direction.

[0057] The above-described movement fixing member (140) may preferably have a structure that is screw-connected to the rear of the drilling guide member (130) by passing through the sliding slit portion (111) of the plate member (110). Preferably, a female screw portion is formed at the rear of the drilling guide member (130), and the movement fixing member (140) is formed as a male screw portion, so that the movement fixing member (140) can be screw-connected to the rear of the drilling guide member (130).

[0058] Of course, a male screw portion may be formed extending to the rear of the drilling guide member (130), and a female screw portion may be formed on the movement fixing member (140) to allow screw connection.

[0059] As described above, the fixed member (140) is configured to move and rotate along the sliding slit portion (111) in a connected state with the drilling guide member (130) according to the operator's operation, or to maintain a connected and fixed state with the drilling guide member (130), as shown in FIGS. 5 to 8.

[0060] In addition, it is preferable that the head portion of the fixed member (140) be knurled so that the operator can easily rotate it by hand, as shown in FIGS. 7 and 8, and it is more preferable that the outer diameter of the male screw portion be manufactured to correspond to the slit height of the sliding slit portion (111) so that the male screw portion is inserted into the sliding slit portion so that there is no vertical shaking when the fixed member moves horizontally.

[0061] The surgeon bends the plate member (110) of the multiple implant placement guide device of the present invention to correspond to the arch shape of the patient of the present invention as shown in Fig. 3 (b), and then manipulates each movable fixing member (140) to precisely move the position of each drilling guide member (130) along the sliding slit portion (111), and at the moved position, the inclination angle of each drilling guide member (130) can be set to the intended angle and fixed.

[0062] Next, in a state where the exact position or exact rotation angle of each drilling guide member (130) is set in the plate member (110), the operator can perform stable drilling work by placing the drill member (20) on each drilling guide member (130).
