Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fixing a surgical guide for a dental implant using a positioning piece,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for fixing a surgeon's guide for performing a dental implant using a alignment piece, and more particularly to a method for fixing a surgeon's guide, The present invention relates to a method for fixing a surge guide for a surgical procedure.

Generally, an implant refers to a substitute for replacing a human tissue when the original human tissue is lost, but refers to implanting an artificial tooth in the dentistry. That is, a fixture made of titanium or the like which does not have a rejection reaction to the human body can be substituted for the lost root, and then the teeth are inserted into the alveolar bone, and the tooth is restored by fixing the artificial tooth.

At this time, the implant procedure consists of forming a hole in the alveolar bone, placing the fixture, and then joining the abutment and the crown to the fixture. Here, a procedure for forming a perforation and a procedure for placing a fixture vary from patient to patient. This is because the position, direction, and depth of the implant are determined in consideration of various factors such as the state of the alveolar bone of the patient and the position of the tooth requiring the implant.

As a result, it is difficult to precisely measure the depth and direction of the procedure, not only for the novice who does not have experience of the operation, but also for the experienced person.

Recently, a surgical guide has been made by using 3-D image obtained through CT scan and oral scan of the patient's mouth and perforation drilling and fixture placement using a surge- An assisted method is used.

The surge guide includes a guide body formed with a guide hole corresponding to the fixture mounting position and a sleeve inserted and coupled to the guide hole so as to be rotatably supported on the inner periphery of the implant drill. In addition, the guide body is formed with a fixing groove portion which is seated to surround the outer surface of the gum to be implanted.

On the other hand, in order to accurately place the fixture at a position where implantation is to be performed, the outer surface of the fixed groove and the outer surface of the gum must be substantially fixed. At this time, in the case of a patient having relatively few teeth missing from the gums, since the outer surface of the remaining tooth, which is a substantially rigid portion, is fitted with the fixing groove portion, the swinging motion of the surge guide is minimized.

However, in the case of a dental dental patient having a large tooth defect or a large number of missing teeth, the amount of the fluid of the tissue is high and the shape thereof is not clearly specified. Therefore, when the surge guide is installed, And it is difficult to fix.

Therefore, even if the fixture is placed through the guide hole formed in the surge guide, the fixture can be placed at a position deviated from the implant construction design value. This may be a fatal cause of detachment or breakage of the abutment by fixing the abutment and the crown fixed to the upper side of the fixture at a later time, and there is a problem that the surgeon feels discomfort and re- Respectively.

In the meantime, the dental implant treatment is performed by forming a hole in the alveolar bone using a drill, and placing the fixture in the hole. At this time, an auxiliary device called a surgical guide is used so as to grasp the exact position and direction to perform the drilling operation.

That is, if an implant treatment plan is established according to the state of the inside of the mouth of the patient, the surge guide is manufactured so that the surgeon can guide the established treatment plan and guide the direction or depth of the drilling or fixture placement can do.

As shown in FIGS. 1 to 5B, a method for fixing a surgeon's guide for performing a dental implant using the alignment piece 70 according to the present invention is performed as follows.

First, a primary scanning image 111 and a secondary scanning image 112 obtained by scanning a subject to be implanted by the subject and his / her opposed tooth (t), and a CT image 114 obtained by CT imaging the upper and lower skulls, Align and match. Accordingly, it is possible to acquire the three-dimensional occlusion guide image 115 in which the vertical diameter and the placement position of the object to be implanted are considered with respect to the oral cavity of the subject. Then, a surge guide 60 including a fixing groove portion formed in the tooth placing portion and a guide hole 61 formed along the placing position is manufactured (s1). Here, it is preferable that the tooth placement target portion is a portion that is intended to perform the implant operation due to loss of natural teeth in the maxillary or mandibular interior of the oral cavity.

Specifically, the primary scanning image 111 includes the external shape information of the tooth placement target portion 112, and the secondary scanning image 112 includes external shape information of the opposing tooth t. At this time, each of the scanning images 111 and 112 may be obtained by orally scanning the oral cavity of the subject, or may be acquired by scanning an impression model of the subject by acquiring an impression model of the subject's mouth . The primary and secondary scanning images 111 and 112 are stored in a computer-based image device as three-dimensional vector data.

In addition, the CT image 114 includes information on the shape and bone density of crown and root, and alveolar bone inside the oral cavity, and is stored in the imaging device as three-dimensional vector data.

The three-dimensional occlusion guide image 115 may be acquired by aligning and matching the primary and secondary scanning images 111 and 112 and the CT image 114. [ At this time, it is possible to further obtain the occlusion scanning image so that the primary and secondary scanning images 111 and 112 can be easily aligned corresponding to the vertical height.

In detail, the occlusion scanning image is obtained by installing an auxiliary device such as a tray or splint in which the occlusion height is adjusted in consideration of the prepared denture or the vertical hardness, considering the vertical height of the subject, can do.

At this time, the tray is formed in a shape corresponding to the teeth in the oral cavity, and the impression material is placed on the surface facing the tooth placement target part and positioned between the maxilla and the mandible. When pressure is applied so that the upper and lower jaws are mutually interlocked, a mold groove corresponding to the shape of the teeth to be placed on the gel impression material may be formed into a sound shape.

In addition, the splint is preferably a fixing device provided to substantially fix the reference marker 40, which is a reference of matching of each image, to be described later on the outer surface of the gum with high fluidity of the tooth placement target portion. At this time, the splint sets the tooth placement target portion area surface corresponding to the tooth placement target portion from the primary scanning image 111, and designs the region surface to protrude outward. Accordingly, the area surface can be formed as a mold groove, and the splint designed as described above can be easily manufactured by three-dimensional printing. The reference marker 40 is attached to the upper surface of the tooth placement target portion when the primary scanning image 111 is acquired. In this case, the reference marker 40 is inserted into the splint, can do.

Then, an occlusion base having a predetermined thickness is laminated on the outer surface of the auxiliary device such as the tray or the splint, on which the die groove to be fitted with the tooth placing part is formed, facing the confront tooth (t). Then, the tray or splint is installed in the oral cavity, and the upper surface of the occlusion base formed of the wax or the like is cut according to the sensitivity of the tongue's wearer to adjust the occlusion height according to the tender sensitivity of the subject.

When the tray or splint having the height of the occlusion base is set in the oral cavity as described above and the upper and lower teeth are occluded and scanned, it is possible to obtain an occlusal scanning image in which the vertical diameter is considered. Of course, it is possible to obtain a CT image 114 in which the vertical height is taken into consideration by installing the CT scanner in the denture, the tray, and the splintor mouth, and the method of acquiring the image considering vertical height may be performed according to the manufacturer's manufacturing style Can be flexibly adjusted.

Meanwhile, an integrated scanning image 113 may be acquired by arranging the mutual common portions of the primary and secondary scanning images 111 and 112 and the occlusion scanning images as a comparison region and arranging the vertical and horizontal distances to be considered. Then, the occlusion scanning image may be erased from the integrated scanning image 113, and then the 3D image may be matched with the CT image 114 to obtain the 3D occlusion guide image 115. At this time, the reference markers 40 may be attached to the outer surfaces of the teeth to be placed, the dentures, the trays, and the splints so that alignment and matching standards between the respective scanning images 111 and 112 and the CT images 114 are clearly defined.

In detail, the reference marker 40 has a predetermined volume, such as a cylinder or a polygonal column, and may be displayed at corresponding positions of the scanning images 111 and 112 and the CT image 114, . That is, when the reference markers 40 are attached to the outer surfaces of the tooth placement part, the denture, the tray, and the splint, the reference markers 40 are imaged and displayed at the same positions when they are scanned and CT images. Then, the reference marker 40, which is a common part of each image, is superimposed on the reference, and the comparison area is set. At this time, the comparison area may be set to a point, a line, or a face corresponding to each other in the primary and secondary scanning images 111 and 112 and the reference marker 40 image displayed on the CT image 114. Furthermore, by designating the comparison area at a plurality of locations, the degree of association between the primary and secondary scanning images 111 and 112 and the CT image 114 can be remarkably improved. The three-dimensional occlusion guide image 115 can be obtained by performing the step of correcting each image so that the uppermost part and the outermost part of the comparison area coincide with each other, thereby providing more clear information for the implant procedure.

Of course, the primary and secondary scanning images 111 and 112 may be matched with a portion corresponding to the CT image 114 considering the vertical height as a matching reference. That is, the primary and secondary scanning images 111 and 112 may be aligned with the CT image so as to take into account the vertical height, and the primary and secondary scanning images 111 and 112 ), And these modifications are within the scope of the present invention.

In addition, the surge guide 60 can be manufactured in consideration of the external shape information of the tooth placement target portion included in the 3D-guided guide image 115 and the placement relationship of the confrontation tooth (t). Here, the surge guide 60 includes a fixing groove portion formed in the tooth placing portion and a guide hole 61 for guiding the placing position of the object.

In detail, the fixing groove portion can be designed from the external shape information of the tooth placement target portion. At this time, the external shape information of the tooth placement target portion is calculated from the primary scanning image 111, and the placement relationship of the opposing teeth t can be obtained from the secondary scanning image 112. [

Further, the external shape information of the tooth placing part included in the primary scanning image 111 may be obtained by directly scanning the inside of the mouth, or may be obtained by using a denture, a tray, or a splint, And may be obtained by scanning.

In detail, since the mold groove formed on the inner surface of the denture, the tray, the splint, and the like is substantially formed with the tooth placement target portion, the fixing groove portion of the wedge guide 60 can be easily designed from the mold groove image. Of course, it is also possible to design the fixing groove portion to be formed with the outer surface of the tooth placement target portion by inverting the protruded image after scanning the outer surface of the tooth placement target portion, and such a modification falls within the scope of the present invention.

When the fixing groove is designed, the direction of the guide hole 61 is set so as to be parallel to the fixture mounting direction on the basis of the state where the surge guide 60 is fixed to the gum portion of the subject, The guide 60 can be manufactured. Accordingly, the surgeal guide (60) can be installed on the tooth placement part to precisely guide the placement position of the fixture, so that the reliability of the implant treatment can be remarkably improved.

However, in the edentulous patient, the tooth placement part is exposed to the soft tissue gums having a substantial fluidity, and even if the fixing groove part formed with the tooth placement part is formed, the gum is somewhat flowed due to the fluidity of the gum . As a result, as the position of the guide hole 61 is deviated from the substantially planned fixture mounting position, there is a problem that the placing position of the molding is generally inaccurate. This also affects the fixation position of the abutment and the crown which are fixed to the upper side of the fixture at a later time, which causes a discomfort feeling to the person who tries to work, and the disposition or breakage of the disposable article occurs.

Accordingly, the present invention solves the above-mentioned problems and suggests a method capable of performing a highly precise implant treatment.

In detail, the occlusion alignment guides 80a and 80b, which extend so as to correspond to the ends of the primary scanning image 111 and the secondary scanning image 112 aligned in correspondence with the vertical height, 1 sorting-up models 511A and 511B and second sorting-up models 512A and 512B (s2).

The first aligning and pulling up models 511A and 511B and the second aligning and pulling up models 512A and 512B provided with the surge guides 60 are assembled vertically by engaging the ends of the respective occlusion aligning guides 80a and 80b, Are arranged so that the hardness is taken into consideration. The guide hole 61 is formed on the outer surface of the body 71 filled with the space between the surge guide 60 and the opposing tooth t to guide the occlusion position, The alignment piece 70 is formed (s3) in which the inwardly projecting mold portions 72a and 72b are formed so as to solidify the end shape of the tooth t.

4A and 4B, the first sorting-up model 511A and the second sorting-up model 512A include the first scanning image 111 including the occlusion alignment guides 80a and 80b, And the secondary scanning image 112 are converted into three-dimensional vector data and stored in the image matching apparatus.

In detail, the first sorting-up model 511A and the second sorting-up model 512A are arranged such that the occlusion-aligning guides 80a and 80b are respectively imaged and arranged in the outer portions of the primary and secondary scanning images 111 and 112 do. At this time, it is preferable that the occlusion alignment guides 80a and 80b are extended so that the respective ends of the occlusion alignment guides 80a and 80b contact with each other on the image, and the extended length corresponds to the vertical height.

The image of the surge arrester (60) is virtually arranged above the image corresponding to the tooth placement target portion of the primary scanning image (111). Here, the image of the surge arrester 60 may be imaged on the upper side of the first sorting raise model 511A by imaging the value calculated in the manufacturing step of the surge guide 60 described above. Of course, the occlusal alignment guides 80a and 80b may be arranged together in a process of designing the surge arrester 60, and such a design sequence may be flexibly changed according to the design style of the manufacturer .

A gap area is set between the upper side of the guide hole 61 of the surge guard 60 virtually arranged in the first sorting-up model 511A and the tooth end shape of the second sorting-up model 512A, The alignment piece 70 is designed. Here, it is preferable that the gap region is set to a range that overlaps a part of the upper surface of the surge guide 60 and a part of the end of the opposing tooth (t). Since the second aligning-up image model 512A is obtained from the second scanning image 112 that has scanned the outer surface of the opposed tooth t, the end of the opposed tooth t is the second alignment- Is preferably understood to have the same meaning as the end shape of the teeth shown in the model 512A.

Here, the gap region may be formed into a body portion 71 that supports a space between the upper surface of the surge guide 60 and the confrontation tooth t in a subsequent three-dimensional printing. The outer surface of the body part 71 is designed to be formed with inverted molded parts 72a and 72b corresponding to a part of the upper surface of the guide hole 61 and an end shape of the opposing tooth t. That is, the first fused portion 72a corresponding to the protruded outer shape of the opposing tooth t is formed in a concave engraved shape and the second fused portion 72b corresponding to the hollow inner shape of the guide hole 61 ) Can be formed with a convex embossing.

The gap region designed to include the shape of the guide hole 61 and the opposing tooth t is formed on the outer surface of the body 71 as shown in FIG. So as to produce the three-dimensionalized alignment piece 70.

The first alignment groove 72a is formed on the outer surface of the body portion 71 of the alignment piece 70 so as to be inwardly protruded from the second aligning marking model 512A. A second mold groove 72b designed to be reversed from the first aligning drawing model 511A may be formed so as to match the inner periphery of the upper side of the guide hole 61 of the surge guide 60. [ Since the alignment piece 70 can be simultaneously designed in the design process for the registration of the scanning images 111 and 112 and the manufacturing of the surge guide 60, the alignment piece 70 can be easily manufactured, The degree of coupling can be remarkably improved.

5A and 5B, the first sorting-up image model 511B and the second sorting-up image model 512B may include the first scanning image 111 (FIG. 5A) including the occlusion alignment guides 80a and 80b ) And the secondary scanning image 112 are three-dimensionally printed.

At this time, since the occlusion alignment guides 80a and 80b respectively extend in correspondence to the vertical height, the first alignment lift-up model 511B and the second alignment lift- 512B may be arranged corresponding to the vertical diameter.

Here, the manufactured surge guide 60 is installed outside the first sorting-up model 511B. Then, the gap between the surge guide 60 and the second aligning-up model 512B, which is three-dimensionally printed, A putty capable of deforming the shape before curing is injected. At this time, the curable pulling-up resin is pulled by the surge guide 60 provided on the three-dimensionally printed first sorting pulling model 511 and a part of the tooth-shaped end of the three-dimensional printed second sorting pulling model 512 Lt; / RTI > Here, the tooth of the second sorting-up model 512 is preferably interpreted to mean the opposed tooth t.

When the injected pulling resin is cured, the body portion 71 supports the space between the surge guide 60 and the opposing tooth t. At this time, the pulling resin is injected so as to cover the end of the engaging tooth (t) and the upper side of the guide hole on the upper surface of the surge guide (60). Thus, the injection portions 72a and 72b in which the upper side of the guide hole 61 and the tooth end shape are inverted, respectively, can be formed on the injected pulling resin. That is, the first fused portion 72a corresponding to the protruded outer shape of the opposing tooth t is formed in a concave engraved shape and the second fused portion (corresponding to the hollow inner shape on the upper side of the guide hole 61) 72b may be formed in a convexly embossed shape.

At this time, the curable pulling-up resin is preferably injected such that the upper side of the guide hole 61 and a part of the end of the opposing tooth t are covered. Of course, the curable pulling-up resin may be injected so that the front surface of the surge guide 60 and the entire opposing tooth t are covered. In this case, however, after the curing resin is cured, It is difficult to separate the tooth from the opposing tooth (t). Therefore, the guide hole 61 and the end of the opposing tooth t are engaged with the engaging portions 72a and 72b while being easily separated from the surge guide 60 and the opposing tooth t, It is preferable to inject the impression resin to such an extent that the impression resin can be used.

In addition, a fastening protrusion 81b and a fastening protrusion 81b for guiding the first sorting-up model 511B and the second sorting-up model 512B to be fastened in the vertical direction are formed at corresponding ends of the occlusion alignment guides 80a and 80b, And fastening grooves 81a may be respectively formed. At this time, it is preferable that the fastening protrusion 81b and the fastening groove 81a are formed to correspond to the extending direction of the occlusion alignment guides 80a and 80b.

Accordingly, the first sorting-up model 511B and the second sorting-up model 512B are separated from each other in parallel so that unnecessary grooves are formed in the aligning piece 70 except for the molding parts 72a and 72b It is possible to prevent squeezing. Thus, since the alignment piece 70 can be disposed inside the oral cavity provided with the surgeal guide 60 to guide the correct occlusion position, the reliability of the implant treatment can be remarkably improved.

The alignment piece 70 is inserted into the oral cavity of the subject who is provided with the surge guide 60 so that the guide hole 61 and the end of the opposing tooth t are respectively formed in the molded parts 72a and 72b. And the upper and lower jaws are engaged to start the position of the surge guide 60. Then, the fixing pin, which is passed through the side surface of the surge guide 60 and has an end fixed to the gum, is fastened (s4).

In detail, the outer surface of the alignment piece 70 is provided with a fitting portion 72 to be engaged with the guide hole 61 of the surge guide 60 and a fitting portion 72a, 72b are formed. At this time, the respective engaging portions 72a and 72b may be three-dimensionally formed corresponding to the inner shape of the guide hole 61 and the outer shape of the tooth end of the opposing tooth t.

The alignment piece 70 is provided between the surgeal guide 60 and the opposed tooth t in a state where the surgeon's guide 60 is installed inside the oral cavity, The inner periphery of the upper side of the guide hole 61 and the end of the opposing tooth t are constrained to the engaging portions 72a and 72b. Thus, it is possible to precisely engage and fix not only the upper and lower positions of the upper and lower legs but also the front and rear right and left positions.

When the position of the surge guide 60 is aligned as described above, the fixing pin is inserted and placed through the through hole 64 penetrating from the side surface of the surge guide 60 toward the gum side. Here, the fixing pin may include a head portion formed to have a predetermined thickness so as to be attached to a surgeon with a hand or a tool, the head portion having a contact surface to be closely contacted with the side surface of the surge guide, It includes the government. At this time, the threaded portion may be formed at the end of the fixing portion so as to be firmly mounted on the gum. When the fixing pin is fastened, the side surface of the surge guide 60 is restrained between the head portion provided on the fixing surface and the gum where the end portion of the fixing pin is placed. Here, the end of the fixing pin is preferably the same as the end of the fixing part.

Here, the side surface of the surge guide 60 may be formed with a flat portion 63 which is in contact with the inner surface of the head portion. That is, the flat outer surface of the flat portion 63 and the inner surface of the head portion are parallel to each other, and the through hole 64 is perpendicular to the outer surface of the flat portion 63, Can be stably and firmly fixed.

Accordingly, it is possible to prevent the surge guide 60 from flowing in the vertical direction as well as in the front, back, and left and right directions, thereby firmly mounting the surge guide 60. In order to align the surge arrays 60, alignment pieces 70 are formed on the ends of the opposed teeth t and the guide holes 61 of the surge arrays 60, respectively, The alignment accuracy can be remarkably improved.

At this time, since the mold parts 72a and 72b formed on the outer surface of the alignment piece 70 are formed in a three-dimensionally reversed shape corresponding to the guide hole 61 and the end of the opposing tooth t, . If the alignment piece 70 is provided in the oral cavity so that the upper inner circumference of the guide hole 61 and the end of the opposing tooth t are confined to the mold-fit portions 72a and 72b, A more precise alignment of the guide 60 is possible.

Thus, since the surgeon guide 60 for guiding the placement position of the object using the alignment piece 70 is fixed so as to be substantially coincident with the preset implant position, the placement of the fixture can be performed with high accuracy And the position accuracy of the sequentially fixed abutment and crown can be improved.

The alignment piece 70 is formed on an outer surface of a body portion 71 filled to fill a space between the surge guide 60 and the confrontation tooth t, the end portions of the surge guide 60 are formed to be inverted in three dimensions so that the surgeon guide 60 can be fixed to the correct position corresponding to the implant construction design even on the gums having fluidity of the edentulous patient. Accordingly, since the reliability of the implant treatment is remarkably improved, the satisfaction of the procedure practitioner can be remarkably improved.

At this time, the alignment piece 70 includes a first alignment impression model (not shown) arranged in consideration of the vertical height calculated through the matching between the images 111, 112, and 114 obtained by scanning and CT images of the tooth placement target portion and the opposed tooth t, The positioning accuracy of the surge guide 70 using the alignment piece 70 can be remarkably improved.
