Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an implant surgical guide device and a method of implanting an implant using the same.

The present invention relates to an implant surgical guide apparatus set and an implant placing method using the same, and more particularly, to an implant surgical guide apparatus and a method of implanting an implant, which is configured to smoothly form an implant treatment hole using a guide portion even at a position with a short inter- A surgical guide device set, and an implant placing method using the same.

In dentistry, an implant refers to the removal of a problematic or lost tooth, followed by the implantation of an artificial tooth. Implants have the advantage of restoring (restoring) only the parts without teeth without removing the natural teeth.

These implants can be used semi-permanently because they have the same function and shape as the natural teeth but do not cause tooth decay.

Brief description of the implant procedure, the practitioner uses the dedicated drill to form the implant treatment ball in the alveolar bone at the position where the implant is to be installed.

Next, a fixture is combined with the implant treatment ball to osseointegrate the alveolar bone and the fixture. At this time, the fixture supports a prosthesis having an artificial tooth shape.

The fixture is preferably inserted into the implant treatment hole formed on the alveolar bone, and is preferably made of a material that does not show a rejection reaction with the human body.

Next, in the state where the alveolar bone and the fixture are fusion-bonded, the abutment is combined with the fixture.

Next, the implant is completed by connecting the artificial teeth with the abutment being covered.

The process of forming an implant treatment ball on the alveolar bone using the drill during the implant procedure is very important.

This is because the direction and depth of the implant treatment ball may vary depending on various factors such as the patient's tooth condition, the position of the tooth where the implant is performed, and the alveolar bone condition of the patient.

In order to stably and precisely form such an implant treatment ball, a guide portion for guiding the movement of the drill may be used. However, when the implant is placed at a position where the intermaxillary distance is short, such as molar teeth, the guide portion can not be used . That is, since the position of the molar teeth is short, it is difficult to drill into the inside of the guide part, which makes it difficult to form an implant treatment ball.

Meanwhile, in the related art, there is no separate device for grasping the rotational position of the fixture coupled to the alveolar bone in incorporating the fixture into the implant treatment ball. That is, the fixture coupled to the alveolar bone is difficult for the practitioner to visually confirm and determine the rotation position of the fixture. Therefore, the rotation position of the fixture is determined according to the experience of the practitioner. Therefore, when the abutment and the artificial tooth are combined with each other in a state where the fixture is not positioned at the correct rotational position, there is a problem that the artificial tooth is dislocated in a wrong state instead of the correct position. That is, there is a problem that the artificial tooth can not be arranged properly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view illustrating a state of use of the implant guide apparatus set according to the first embodiment of the present invention. The implant guide guide apparatus set 1000 may include a drill apparatus 100 and a guide apparatus 200.

The implant guide apparatus set 1000 includes a guide device 200 so that a practitioner can form an implant treatment hole at an exact position and depth in an alveolar bone (not shown) using the drill apparatus 100.

The drilling apparatus 100 is configured to form an implant treatment hole in the alveolar bone and the drilling apparatus 100 may include a power transmission shaft 110, an engagement portion 120, a drill head 130, and a drill 140 have. That is, the rotational force generated from the power unit 150 is transmitted to the power transmission shaft 110, and the rotational force transmitted to the power transmission shaft 110 is transmitted to the drill 140 that is integrated with the power transmission shaft 110 , And the drill 140 forms an implant treatment hole in the alveolar bone. At this time, the power unit 150 may be a motor or the like.

As described above, the drill apparatus 100 is moved along the guide unit 300 provided in the guide apparatus 200 and forms an implant treatment ball on the alveolar bone. The guide part 300 is provided with a step 301 for restricting the movement of the drilling device 100, thereby selectively controlling the depth and direction of the implant treatment hole formed on the alveolar bone.

The guide device 200 may include a guide part 300 and a tooth frame fixing part 240.

It is needless to say that the guide part 300 supported by the tooth frame fixing part 240 may be composed of one, two, three, four or the like. That is, the number of the guide portions 300 is not limited to a specific number, and may be various numbers. In the case where the guide part 300 is formed of two or more pieces, the guide parts 300 may be provided so as to be adjacent to each other, And can be variously positioned depending on the position.

The guide portion 300 is selectively adjusted according to various factors such as the patient's tooth condition, the position of the tooth where the implant is performed, and the alveolar bone condition of the patient.

In other words, the patient who undergoes the implant procedure will be able to accurately grasp the tooth condition through computed tomography (CT), and the direction and depth of the implant treatment ball will be determined according to the state of the tooth.

For example, by analyzing a patient's teeth three-dimensionally through a three-dimensional computerized tomography, the tooth information of the operation site can be grasped more concretely. That is, various information about the patient's gingiva, alveolar bone, etc. can be accurately obtained through 3D computer tomography without directly cutting the patient's gingiva.

The guide device 200 is manufactured based on the information obtained through the computer tomography.

In other words, the tooth frame fixing unit 240 can be manufactured in the form of a rectangular frame or an upper frame for all the teeth except for the lower teeth or the upper teeth where the implant is to be implanted. That is, the tooth frame fixing part 240 has a shape corresponding to a relief shape with respect to the teeth of a relief shape, and is made to be covered and fixed to the teeth.

For example, when the patient applies the implant only to the lower teeth, the tooth frame fixing portion 240 is manufactured in the form of a rectangular frame. When the implant is applied only to the upper teeth, the tooth frame fixing portion 240 is manufactured as a top knife frame.

If the patient is to be implanted in the lower and upper teeth, the dental implant fixture 240 will be fabricated in the form of a lower limb and an upper lip, respectively.

Referring to FIG. 1, the tooth frame fixing portion 240 shown in FIG. 1 (a) is a form that can be fitted to all of the lower teeth except the lower teeth to be implanted, and FIG. The tooth frame fixing portion 240 is fitted only to a part of the lower limb to be implanted.

In this way, the practitioner can selectively adjust the size of the tooth frame fixing part 240 according to the condition of the patient's teeth.

The tooth frame fixing part 240 is configured to support and fix the guide part 300. The tooth frame fixing part 240 has a shape corresponding to each tooth except for the lower teeth or upper teeth where the implant is to be implanted and is fitted to each tooth.

The tooth frame fixing part 240 shown in FIG. 1 illustrates the tooth frame fixing part 240 having a rectangular frame shape as an example.

The tooth frame fixing part 240 is manufactured in a shape fit to individual teeth of a patient through a computed tomography. Accordingly, the tooth frame fixing part 240 is in a form corresponding exactly to the patient's teeth, and the guide part 300 is stably fixed.

The teeth fixing part 240 may be integrally formed with the guide part 300 and the guide part 300 may be detachable from the tooth fixing part 240.

3 is a front view of the guide unit according to the first embodiment of the present invention. FIG. 4 is a cross-sectional view taken along line AA of FIG. 2. FIG. And Fig. Members denoted by the same reference numerals as those of the members shown in Fig. 1 have the same configuration and function, and a detailed description thereof will be omitted.

As shown in FIGS. 2 to 4, the guide portion 300 may further include an opening 320. At this time, the opening portion 320 is formed to extend along the circumference of the body portion 310.

The opening part 320 forms a space 311 with the body part 310 and can be supported on the body part 310 by the connecting member 312. At this time, the connecting member 312 is configured to easily separate the opening portion 320 from the body portion 310 when the operator applies a force greater than a certain amount to the opening portion 320.

For example, when the practitioner rotates the opening 320 by applying a certain amount of force to the upper end or the lower end of the opening 320, the connecting member 312 provided on both sides of the opening 320 may be twisted And is cut off from the body portion 310. That is, a space 311 is formed between the opening part 320 and the body part 310 so that the opening part 320 can be easily separated from the body part 310. It goes without saying that the opener 320 may be used as it is without removing or removing it as needed.

At this time, the length of the opening 320 is shorter than the length of the body 310, so that the body 310 is prevented from being completely disconnected when the opening 320 is separated from the body 310 .

When the opening portion 320 is separated from the body portion 310, the insertion space portion 330 is formed. The insertion space 330 facilitates entry of the drill 140 from the outside.

That is, when the drill 140 of the drill apparatus 100 is guided to the inside of the guide unit 300 in order to form an implant treatment hole, the drill 140 is moved from one end of the body unit 310 in the direction of implant placement The drill 140 can be inserted into the side surface of the guide portion 300 through the insertion space portion 330. [

The operator removes the opening 320 from the body 310 and inserts the drill 140 of the drilling device 100 into the drill device 100 when the implant is placed at the same position as the molar teeth, And can easily enter the inside of the guide portion 300 through the space portion 330.

Thus, the practitioner can smoothly form the implant treatment ball even when the patient does not spread his / her mouth wide. That is, the practitioner can perform the implant operation while selectively separating the open portion 320 according to the implant placement position. Therefore, it is possible to improve the convenience of the patient during the implant procedure and to reduce the difficulty of the operation.

In the case of using the guide part 300 for opening the opening part 320 from the body part 310 in the operation of the patient having the same intermaxillary distance as described above, It is also possible to enhance the convenience of the user.

The guide portion 300 is formed with a rotation reference groove 302. The rotation reference groove 302 is positioned so as to be opposed to the opening 320 to set a rotation position reference of the fixture 800 (refer to FIG. 13) to be placed on the alveolar bone.

FIG. 5 is a perspective view of a guide unit according to a second embodiment of the present invention, FIG. 6 is a front view of a guide unit according to a second embodiment of the present invention, and FIG. 7 is a cross- Fig. Members denoted by the same reference numerals as those of the members shown in Fig. 1 have the same configuration and function, and a detailed description thereof will be omitted.

Specifically, the guide unit 300 'shown in FIGS. 5 to 7 has only a difference in position between the guide unit 300 shown in FIGS. 2 to 4 and the connecting member.

That is, in FIG. 5, the connecting member 312 'of FIG. 6 is provided on the lower surface of the opening 320, unlike the connecting member 312 is provided on both sides of the opening 320.

When the user releases the opening 320 from the body 310, the operator applies a certain amount of force to the upper end of the opening 320 to break the connecting member 312 'from the body 310 . It goes without saying that the opener 320 may be used as it is without removing or removing it as needed.

The connecting members 312 and 312 'connecting the body portion 310 and the opening portion 320 are not limited to the positions of both side surfaces or the bottom surface of the opening portion 320, Of course.

8 is an exploded perspective view of a guide unit according to a third embodiment of the present invention. Members denoted by the same reference numerals as those of the members shown in Fig. 1 have the same configuration and function, and a detailed description thereof will be omitted.

Referring to FIG. 8, an opening portion 420 provided in the guide portion 400 extends along the circumference of the body portion 410.

A protrusion 421 is formed in the opening 420 and a receiving groove 411 corresponding to the protrusion 421 is formed in the body 410 so that the opening 420 is selectively inserted from the body 410 Can be separated. Alternatively, the opening 420 may have a receiving groove, and the body 410 may have a protrusion.

That is, when separating the opening part 420 from the body part 410, the operator pulls the opening part 420 in the longitudinal direction of the guide part 400, thereby opening the opening part 420 from the body part 410 It can be completely separated.

The length of the opening 420 is shorter than the length of the body 410 so as to prevent the body 410 from being completely disconnected when the opening 420 is separated from the body 410 .

10 is an exploded perspective view of a mount assembly according to the present invention, FIG. 11 is a perspective view of a fixture according to the present invention, FIG. 12 is a perspective view of a guide part according to the present invention, Fig. 10 is an exemplary view showing a mount assembly in which inserted fixtures are combined.

9-12, the set of implant surgical guide devices 1000 may further include a mount assembly 700 and a fixture 800.

The mount assembly 700 and the fixture 800 are used after forming an implant treatment hole in the alveolar bone using the drilling apparatus 100. [

The mount assembly 700 may include a mount screw 500 and a mount body 600. The mount assembly 700 may include a mount screw 600 and a mount body 600. The mount assembly 700 may include a fixture 800,

The mount screw 500 is screwed with the fixture 800 so that the insert screw 510 is inserted into the insert bar 510, the first thread 520, the head 530, and the O-ring 540 .

The insert bar 510 has a cylindrical shape and forms the length of the mount screw 500. The insert bar 510 is inserted into the through hole 601 formed in the mount body 600 and the first thread 520 provided at one end of the insert bar 510 is inserted into the fixture 800 The second screw thread 810 may be screwed into the second screw thread 810. [

The head portion 530 is provided at the other end of the insertion bar 510. The head portion 530 is formed to have a diameter larger than the diameter of the through hole 601 so that the engagement is generated in a state where the insertion bar 510 is inserted into the through hole 601. That is, when the head part 530 comes into contact with the mount body 600 while the insertion bar 510 is inserted into the through hole 601 and is moved forward while being engaged with the fixture 800, RTI ID = 0.0 > 510 < / RTI > The head portion 530 is not limited to a circular shape but may be formed in various shapes such as a polygonal shape.

A polygonal groove 531 is formed on the upper surface of the head portion 530 and a first driver (not shown) is coupled to the inside of the polygonal groove 531. That is, the first screw driver rotates the mount screw 500 in the forward or reverse direction while being engaged with the polygonal groove 531. In this case, the forward rotation refers to rightward rotation for coupling the first screw 520 and the second screw 810, and the reverse rotation refers to the right rotation for separating the first screw 520 and the second screw 810 In the left direction. Here, when the first screw thread 520 and the second screw thread 810 are left-hand threads, the directions of the forward rotation and the reverse rotation are reversed.

The O-ring portions 540 are provided in a spaced-apart space of the head portion 530 forming a pair of spaced spaces. The role of the O-ring portion 540 will be described later.

The mount body 600 is formed with a through hole 601 so that one end of the mount screw 500 is inserted into the guide body 300 and has an outer diameter corresponding to the inner diameter of the guide portion 300, .

The mount body 600 may include a driver coupling portion 610, a rotation adjusting portion 620, a body portion 630, and a fixture supporting portion 640.

A second driver (not shown) is coupled to the outer surface of the driver coupling portion 610 so that the mount body 600 can be rotated according to the rotation of the second driver. That is, the rotational force transmitted to the driver coupling portion 610 through the second driver is finally transmitted to the fixture 800, and the fixture 800 can be rotated and inserted and fixed in the implant treatment ball formed on the alveolar bone.

At this time, the second driver is coupled to the driver coupling portion 610 in a state of wrapping the head portion 530 and the driver coupling portion 610. At this time, the O-ring portion 540 is elastically deformed and is brought into close contact with the inner surface of the second driver. Therefore, the second driver tied to the driver coupling portion 610 can be prevented from loosely separating from the driver coupling portion 610 easily.

The driver fixing portion 610 has a hexagonal cross section and the rotation adjusting portion 620 has a hexagonal shape. The fixture supporting portion 640 is also formed in a hexagonal shape. However, the driver fixing portion 610, The fixture 620 and the fixture support 640 may have various regular shapes.

However, the rotation adjusting unit 620 and the fixture supporting unit 640 are formed in a regular polygonal shape having the same number of sides but differing in the size of the circumscribed circle, and each side is always positioned in the same direction.

The rotation adjusting unit 620 is provided at a lower portion of the driver coupling unit 610. The rotation adjustment unit 620 is configured to grasp the rotation state of the mount assembly 700, and ultimately, the rotation state of the fixture 800 is grasped. A round portion may be formed at a portion where each side 621 of the rotation adjusting unit 620 meets.

In other words, after the mount screw 500 is inserted through the hole 601, the first screw 520 is screwed into the second screw thread 810 formed in the fixture 800, Shaped mount assembly 700 is inserted into the guide portion 300 and is guided by the guide portion 300. The fixture 800 is inserted into the previously formed implant treatment hole and is placed.

The operator controls the rotation position of the fixture 800 through adjustment of the rotation reference groove 302 formed in the body 310 and the rotation adjusting unit 620. That is, any one side surface 621 of the rotation adjusting unit 620 having a regular polygon is rotated (rotated) so as to be parallel to the imaginary line segment s connected to the inner diameter side edge of the guide unit 300 formed by the rotation reference groove 302 And the rotation position of the fixture 800 is adjusted by rotating the adjustment unit 620.

In other words, in the final step of placing the fixture 800 in the alveolar bone along the guide part 300, the rotation adjusting part 620 is selectively moved in parallel with the virtual line segment s so that the side surface 621 of the rotation adjusting part 620 is parallel to the virtual line s The rotation position of the fixture 800 can be accurately specified.

Thus, the practitioner does not adjust the rotational position of the fixture 800 according to the experience of the practitioner, but directly confirms the side 621 of the rotation adjusting unit 620 and the virtual line segment s in parallel, The rotation position of the fixture 800 can be precisely specified by selectively rotating the fixture 700.

Therefore, when the fixture 800 is fixed to the alveolar bone and the rotation position of the fixture 800 is precisely specified, it is possible to prevent the artificial teeth from being inserted in the wrong state when the abutment and the artificial tooth are combined with each other. That is, the artificial teeth can be arranged.

The body portion 630 is provided at a lower portion of the rotation adjusting portion 620 and has an outer diameter corresponding to the inner diameter of the guide portion 300. That is, when the mount assembly 700 moves along the guide portion 300, the body portion 630 guides the movement path of the mount assembly 700.

The lower portion of the body portion 630 has a truncated conical shape so that the fixture support portion 640 is smoothly inserted into the support portion fixing groove 820.

The fixture support portion 640 is provided at the lower portion of the body portion 630. The fixture support portion 640 has a regular polygonal cross section, and has the same regular polygon as the rotation adjustment portion 620. That is, if the rotation adjusting unit 620 is hexagonal, the fixture supporting unit 640 is hexagonal. However, the rotation adjusting unit 620 and the fixture supporting unit 640 differ in the size of the circumscribed circle. At this time, the size of the circumscribed circle of the fixture supporting portion 640 is smaller than the circumscribed circle size of the rotation adjusting portion 620.

The fixture support portion 640 is inserted into the fixture groove 820 formed in the fixture 800 and transmits the rotational force to the fixture 800 through the screw connection portion 610. That is, the support portion fixing groove 820 has a shape corresponding to the outer shape of the fixture supporting portion 640, so that the rotational force of the mount body 600 can be smoothly transmitted to the fixture 800.

A second screw thread 810 is formed on the inner side of the fixture 800 so as to be screwed to the first screw thread 520 of the mount screw 500. The second screw thread 810 is positioned below the support securing groove 820. A third thread 830 is formed on the outer side of the fixture 800.

The first screw thread 520, the second screw thread 810 and the third screw thread 830 are formed to have the same rotation direction. The first screw thread 520, the second screw thread 810, And the third thread 830 are in the form of a right-hand thread.

In the fixture 800, a movement guide portion 840 is formed to smoothly guide the fixture support portion 640 to the support portion fixing groove 820. That is, the movement guide portion 840 has a shape corresponding to the truncated cone of the body portion 630, and the fixture support portion 640 is fixed to the support portion fixing groove 640 in the process of coupling the first screw thread 520 and the second screw thread 810 820).
