Description

DIGITAL HEALING ABUTMENT [0002]

The present invention relates to a healing abutment which is bonded to a fixture placed on a gum during a dental implant treatment and which heals the gum in a shape corresponding to the cervical portion during healing of the gum And more particularly to providing a predefined marking for easy identification of how deeply the healing abutment has been inserted into the patient's gums, as well as providing the implant with the same shape of the patient's mouth as the subject, To a digital healing abutment which can be easily manufactured.

Dental prosthesis treatment is performed to restore the function of the dental patient. Implant treatment, which is one of the dental prosthodontic treatments, is now the most popular prosthetic treatment.

The implant treatment method described below can be variously performed. The implant treatment method described below includes a fixture level (implant level) technique for completing a model by connecting an impression coping in the oral cavity when the impression is made in the prosthodontic procedure impression method.

Specifically, a drilled hole and a tapping process are performed to form a groove corresponding to a fixture dimension, a mount is fastened to the top of the fixture, and a surgical handpiece To fix the fixture and the mount to the alveolar bone, and then to remove the mount from the fixture to insert the fixture into the alveolar bone. Then, the first operation is completed by sealing the fixture by fastening the lid screw to the upper part of the fixture. The lid screw in this case penetrates into the fixture while bacteria and foreign substances existing in the oral cavity are waiting for the fusion of the fixture. The duration of osseointegration is 3 to 6 months unilaterally, depending on the patient's bone quality and implantation position.

Then, the gingiva was opened through a secondary operation to expose the cover screw, the degree of osseointegration of the fixture was checked, the cover screw was removed, and a healing abutment was fastened on the fixture to form an aesthetic gum Wait for two to three weeks. In order to improve the complexity of the second procedure, a first-aid procedure, in which the procedure of fastening and removing the cover screw is omitted, is used.

Next, after the aesthetic gum formation is confirmed, the abutment abutment is removed, and the impression copings are fastened to the upper part of the fixture for the preparation of the prosthesis. Then, the impression material is used to make a preliminary impression in the mouth and the impression copings are removed. After that, a tooth model is prepared, and an artificial tooth (artificial crown) is pierced, and an abutment is fastened to the top of the fixture to fix a prosthesis (artificial crown) on the abutment to complete an artificial tooth. In this way, a healing abutment is generally used for the aesthetic gingival formation during the implant procedure.

For example, Korean Patent Laid-Open No. 10-2009-0110136 discloses a "healing abutment of an implant structure having a healing cover ".

The present invention is characterized in that the healing cover is coupled to the fixture immersed in the alveolar bone to combine the abutment and to cover the outer surface exposed to the outside of the abutment of the abutment.

As described above, current healing abutments have generally been provided as means for strengthening the bond with the prosthesis, or for ensuring that the gums are kept clean and excellent in beauty. On the other hand, in order to obtain such an effect, a means and a method for accurately grasping the detailed information inserted in the fixture by the first acicular healing abutment should be presented.

In particular, in recent years, physicians hope to perform a primary test through a oral model including a healing abutment inserted into the patient's mouth prior to mounting the tooth-shaped prosthesis to the patient's treatment site. For this reason, doctors are asking the manufacturers of healing abutments the same oral model as the patient's mouth.

In order to carry out the above-described clearer test, it is necessary that the oral cavity model having the same shape as the oral cavity with the sample including the healing abutment inserted into the oral cavity of the patient in the ratio of 1: 1 is the same and the oral care model of the healing abutment The insertion type, such as direction and depth, should be the same insertion type in the mouth model and the actual patient's mouth.

However, the healing abutment provided so far has not been able to confirm insertion information such as direction, position and depth of the sample healing auberties inserted in the patient's mouth, or was made in a very inconvenient manner, When the abutment is inserted into the impression material, the position is not fixed to the impression material, or the impression material is separated by the clearance between the impression material and the healing abutment, so that a correct oral model can not be manufactured.

In addition, since the insertion depths of the healing abutments differ depending on the patient's mouth, the heights of the healing abutments are also different from each other. On the other hand, in the case of a healing abutment already inserted into the patient's mouth, it is not easy to confirm information about the insertion depth of the healing abutment externally. Therefore, To see the details of the corresponding healing abutment, but this is a very inconvenient method.

The present invention has been made in order to more positively solve the above problems, and it is an object of the present invention to provide a healing abutment including a healing abutment inserted into a patient's mouth, So as to prevent positional deviation and deviation from the clearance between the object and the impression.

Also, in order to insert the insertion information according to the direction, position, depth, etc. of the healing abutment inserted into the patient's mouth into the same information in the oral model, the healing abutment is provided with the reference points of directionality, Another challenge is to shorten the procedure time.

In addition, when combined with the fixture placed on the gingiva, the predefined display is externally exposed so that detailed information such as the outer diameter and length of the healing abutment can be confirmed from the outside, so that the prosthesis can be quickly produced So that the duration of the implant procedure is shortened.

According to an aspect of the present invention, there is provided a digital healing abutment which includes a fastening means (200) for passing through a hollow portion (102) (110) which is inserted into the fixture and has a polygonal cross section, and a support part (110) protruding in the circumferential direction and guiding the shape of the gum while the gum is healed A holding part 130 protruding in a circumferential direction from the supporting part to prevent the shape of the gum from rising beyond a predetermined distance; an outer shape part 140 extending from the holding part to a diameter larger than the holding part; A groove (160) for forming a lateral groove with a predetermined depth along a rim on a boundary line formed with a contour portion from the holding portion and judging whether an accurate depth is inserted when inserting into the gum, Characterized by consisting of; portion is formed to be recessed at one end an upright downward direction indicating groove (170) to determine the X, Y axis orientation position on insertion of the gum.

2 to 4 protrusions 150 are protruded in the direction of the holding part 130 from the end side of the outer shape part 140. As the number of the protrusions increases, The heights of the heel abutment can be detected from the outside by the number of the protrusions. The height of the heel abutment can be determined from the outside do.

Meanwhile, the outer shape part 140 is characterized in that a taper having a vertical reference of 10 to 30 degrees is formed in the direction of the holding part 130 from the end side.

The healing abutment of the present invention having the above-described structure is configured such that the protrusion 150 formed on the outer shape portion 140 and the tapered portion in the direction of the holding portion 130 from the end side of the outer shape portion, It is possible to easily manufacture an oral model having the same shape as that of the patient's mouth by including the sample healing abutment inserted into the mouth of the patient by preventing positional deviation and departure.

In addition, the position of the protrusion 150 and the heel ring inserted into the oral cavity of the patient through the direction indicating groove 170, which is formed to be depressed downward at one side of the outer shape of the outer shape, and which confirms the bearing position of the X and Y axes when inserted into the gum, The insertion information according to the orientation, position, depth, etc. of the abutment can be inserted as the same information in the oral model, thereby omitting unnecessary procedures in the procedure and shortening the procedure time.

In addition, by forming two to four protrusions on the outer portion of the healing abutment, the insertion depth of the healing abutment fastened to the patient's gums can be easily distinguished from the outside in terms of the number of protrusions, And it is possible to perform a quick procedure without a device.

Above all, it provides a predefined mark that prevents foreign objects from entering the interior of the healing abutment and the fixture while the gums are healed, and also allows the healing abutment to easily identify the depth of the patient's gums It is to be noted, of course, that the invention relates to a digital healing abutment which facilitates the production of implant and oral models of the same shape as the patient's mouth through the healing abutment.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

In addition, advantages and features of the present invention and methods of achieving them will be apparent from and elucidated with reference to the embodiments described hereinafter in detail with reference to the accompanying drawings. However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims. And, throughout the specification, like reference numerals refer to like elements.

As shown in FIGS. 1 to 4, the digital healing abutment of the present invention is a digital healing abutment of the present invention, in which a fastening means 200 penetrating through a hollow portion 102 formed as an upper space and a lower portion through an upper space is inserted into a fixture placed in an alveolar bone, A supporting part 120 protruding in a circumferential direction in the connection part to guide the shape of the gum while the gum is being healed, a supporting part 120 protruding in the circumferential direction of the supporting part, (140) extending from the holding part to a diameter larger than that of the holding part, and a lateral groove having a predetermined depth along a rim on a boundary line formed by the holding part A groove 160 for determining whether or not an accurate depth is inserted when inserting the gum into the gum, And a direction indicating groove 170 for confirming the direction.

More specifically, the digital healing abutment 100 may be configured such that the outer contour 140 can be enlarged or reduced in diameter according to the distance between the teeth and the diameter of the supporting part 120 and the holding part 130 It is natural that it can be changed.

The supporting unit 120 and the holding unit 130 are configured to naturally form the shape of the gum while the fastening unit 200 penetrates the hollow part 102 and is engaged with the fixture placed on the gum to heal the gum, .

At this time, since the holding part 130 is formed at an angle which is 10 to 20 degrees more inclined than the supporting part 120, it is possible to prevent the gum from rising up above a certain distance due to inflammation or swelling, In addition, the load applied to the fixture 300 can be dispersed by the chewing motion according to the ingestion of the food of the patient.

2 to 4 protrusions 150 are protruded in the direction of the holding part 130 from the end side of the outer shape part 140. When the number of the protrusions is increased, ), Respectively, so that they can correspond to different teeth according to people. In addition, the number of the protrusions 150 is configured so that the depth of the healing abutment inserted into the teeth can be easily checked from the outside. The description of the projection will be described later in more detail in accordance with the order of drawings.

5, the healing abutment of the present invention includes a protrusion 150 protruding from the outer contour 140 and a protrusion 150 formed along the contour of the contour 140 formed by the retainer 130, A groove 160 formed to define a lateral groove and to determine whether an accurate depth is inserted when inserted into a gum, a direction in which a bearing position of the X and Y axes is detected when inserted into the gum, A tooth model having the same shape as the mouth cavity of the patient can be easily manufactured by forming the guiding groove 170 and the taper having a vertical reference of 10 to 30 degrees in the direction of the holding portion at the end side of the outer shape.

The reason for this configuration is that, in recent years, a physician firstly tested the oral cavity model including a healing abutment inserted in the patient's mouth before the tooth-shaped prosthesis is mounted on the patient's treatment site, I hope. For this reason, doctors are asking the manufacturers of healing abutments the same oral model as the patient's mouth. In order to carry out the above-described clearer test, it is necessary that the oral cavity model having the same shape as the one-to-one ratio with the oral cavity including the healing abutment inserted into the oral cavity of the patient is required, and the direction and depth of the healing abutment The insertion form should be made in the same insertion form in the oral model and in the oral cavity of the actual patient.

On the other hand, in manufacturing a customized healing abutment for a patient's mouth, a fixture is inserted into the alveolar bone, which is a treatment part of the patient, and a healing abutment for the sample is attached to the fixture. At this time, the contour of the same shape as the contour of the sample healing abutment is exposed to the partial impression. As described above, the implant can be obtained by pouring the gypsum into the partial impression containing the external contour of the same shape as the end portion of the external shape, and the implant can be manufactured through the 3D scanner to produce a customized healing abutment suitable for the oral cavity of the patient Do the work. The healing abutment fabricated by computer programing in the above process can produce a large quantity of products as needed.

As shown in FIG. 6, in order to produce a mouth model of the same shape as the patient's mouth after manufacturing the customized healing abutment, the end of the customized healing abutment, to which the fixture is coupled, And then pulled back to the exposed outer grooves to pour gypsum and solidify, and then remove the partial impression.

One of the processes that can produce a model of the same shape as the oral cavity of the patient at the time of making the oral model performed in the above process is the partial lift of the patient's mouth and the normal sample healing abutment If you re-assign a customized healing abutment made with a 3D scanner to the partial impression you have used, it is not easy to determine the exact direction, position and depth of the first sample healing abutment inserted, There is a problem that the position of the customized healing abutment changes when the gypsum water is poured, or is easily separated from the partial impression.

However, according to the present invention, when the heel abutment is reinserted into the partial impression material at the position of the protrusion 150 protruding from the outer shape part 140, the directionality of the healing abutment can be primarily confirmed, The directional position of the X and Y axes can be determined from the direction indicating grooves 170 that are formed so as to be erected downward in the downward direction, so that the directionality of the healing abutment can be grasped secondarily. The correct insertion depth of the healing abutment inserted into the gum is determined through the groove 160 formed by the lateral groove with a predetermined depth along the border on the boundary formed by the outer shape part 140 from the holding part 130 When reinserted in the partial impression, the healing abutment is to be detached from the implant or held so that the positional change does not occur.

Particularly, by forming a taper of 10 to 30 degrees relative to the Y axis in the direction of the holding part from the end side of the outer shape part, the outer groove is gradually formed in a shape corresponding to the taper when the patient is partially pulled up, So that the bonding force is further strengthened when the healing abutment is reinserted into the partial impression.

7, the healing abutment of the present invention includes a protrusion 150 extending from the end of the outer shape part 140 to the holding part 130, and the number of the protrusions is two The number of the protrusions is not limited to four, but may be varied according to another embodiment. The protrusions 150 have different heights from the connecting portion 110 to the holding portion 130 according to the number of the protrusions 150.

More specifically, the structures of the teeth of each patient will be different from each other, and the height at which the teeth grow from the gums, and the distance from the gums to the alveolar bone, will be different depending on the patient's age. Accordingly, it is natural that the healing abutment should have different lengths according to the patient's oral structure, so that the implant should be applied to the left and right teeth at the same height and depth.

Conventionally, a healing abutment so far provided with a small-sized marking on the side of the outer part according to the length of the healing abutment to confirm the insertion depth of the healing abutment inserted into the patient's gums. However, this method was an inconvenient method that had to be used with a separate verification tool because it was occluded or marked by the patient's teeth.

However, in the healing abutment of the present invention, two to four protrusions are formed on the outer circumference of the outer contour portion 140, and the length of the healing abutment is different according to the number of the protrusions, By confirming the number of healing abutments, the length of the healing abutment can be grasped to simplify the confirmation procedure and shorten the procedure time.

In addition, the direction indicating groove 170 serves not only to determine the directionality of the patient's oral cavity and oral cavity model, but also to detect the direction of the patient, The direction indicating grooves 170 indicate the X and Y axis orthogonal data so that an accurate reference point can be obtained and coordinate values can be obtained when the prosthesis is manufactured.

For example, in order to describe a conventional implant procedure step by step, a personal tray in the oral cavity is prepared, a fixture is inserted, and after impression coping is combined, an impression is made, and in order to reproduce the position of the fixture in the mouth, After mounting the analog analog and casting the shape of the lap analog rod by injecting the stones (soft resin) and stones into the lap analog rod, the method of covering the prosthesis by bonding the abutment to the fixture after manufacturing the lab analog In this case, it is difficult to obtain accurate X, Y and Z axis information because the labor time is long and expenditure due to the expense of material expense is extended and lab analog errors are generated in the impression preparing step to produce the same prosthesis as the patient's oral cavity shape . In order to positively solve all the problems, the present invention can acquire information on the X and Y axes through the direction indicating groove 170 in the impression preparing step so that an accurate reference can be secured, and even in a small- The reference axis can be obtained through the direction indicating groove 170 which can be clearly identified with the eye to produce a precise prosthesis and the reference axis can be obtained because a high esthetic and accurate prosthesis is manufactured through the scanning operation with the scanning device. Accordingly, since the implant prosthesis can be manufactured at low cost without the need for a scan device, it is possible to obtain the effect of reducing the cost of the implant treatment of the patient while promoting the development of the laboratory.

In addition, the direction indicating groove 170 can be used for another purpose, i.e., the working means can be combined to allow the positioning of the corresponding digital healing abutment 100 in the oral cavity, So that it is possible to prevent the infection caused by the movement of the patient by the operator's hand.

The heel abutment according to the present invention having the above-described structure includes a protrusion 150 formed on the outer contour 140 and a taper formed in the direction of the retainer 130 from the end of the contour, It is possible to easily prepare an oral cavity model having the same shape as that of the patient's mouth including the healing abutment inserted into the mouth of the patient by preventing the position variation and departure from occurring between the position of the projection 150 and one side Insertion information according to the direction, position, depth, etc. of the healing abutment inserted into the patient's mouth through the direction indicating groove 170 that confirms the bearing position of the X and Y axes when it is inserted into the gum, Can be inserted into the oral cavity model with the same information, thereby eliminating unnecessary procedures in the procedure. In addition, the number of the protrusions may be two to four, and the height of the healing abutment may be different according to the number of the protrusions, so that the depth of insertion of the healing abutment, And the number of blood vessels can be easily identified.

The digital healing abutment can be selected according to the shape of the oral cavity of the patient, and the present invention can broaden the selection range of the digital healing abutment so that the sense of heterogeneity And to improve the reliability of the implantation procedure ultimately. In addition, by providing a configuration that maximizes the patient's discomfort, the satisfaction of the implant treatment can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be clarified. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
