Description

Hybrid healing abutment and method for fabricating the same

The present invention relates to a healing abutment to be used in a dental implant procedure, and more particularly to a hybrid healing abutment and a method for producing the heterogeneous material integrally formed.

In dental care, implantation involves the implantation of artificial teeth, with teeth missing from fixtures made of titanium or titanium alloy that are not rejected by the human body to replace lost roots (roots). After planting in the alveolar bone that is gone, the procedure to fix the artificial teeth to restore the function of the teeth. In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged after time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth and do not cause tooth decay.

Referring to the conventional implant procedure schematically, a groove is formed in the alveolar bone through drilling and tapping processes to match the dimensions of the fixture, and the fixture is embedded in the alveolar bone. When the fixture is anchored to the alveolar bone by bone fusion, a healing abutment is anchored to the fixture to aesthetically rebuild the gums. When the gums are aesthetically rebuilt, the healing abutment is removed from the fixture, an impression coping is fastened to the fixture and the impression is taken by the impression, and a permanent prosthesis, i.e., abutment abutment, is based on the obtained impression. Abutments and crowns are made. Meanwhile, while the permanent prosthesis is manufactured, the healing abutment is refastened to the fixture. When the crown is fabricated, the healing abutment is removed from the fixture again, and a fixing abutment is fixedly fastened to the fixture, and the crown is fixedly coupled onto the fixing abutment.

In the above-described conventional dental implant procedure, the process of fastening and removing the healing abutment to the fixture may be repeated, thereby causing damage and deformation of the gum and alveolar bone, and delaying the dental implant procedure. On the other hand, when the healing abutment is fixedly fastened to the fixture, food may be caught in the healing abutment and its surroundings, and aesthetically unsatisfactory, a protective cap is temporarily applied to the healing abutment. By the way, the protective cap is not coupled by a bonding means such as adhesive, there is a problem that is easily separated from the healing zone.

A tooth-shaped crown formed of a polymer resin material may be detachably covered on the protective cap, and the crown may be elastically in close contact with the protective cap.

An impression cap may be mounted on the abutment protrusion to obtain an impression in the oral cavity while the abutment protrusion is fastened to the fixture.

In another aspect, the present invention, the base forming step of forming the base, and inserting and seating the base in a cavity corresponding to the shape of the hybrid healing abutment in the mold, the injection of the molten polymer resin into the cavity and hardened It provides a hybrid healing abutment manufacturing method comprising an injection injection step to form the abutment projections.

The hybrid healing abutment manufacturing method may further include an adhesive applying step of applying a dental adhesive to a portion of the outer surface of the base bonded to the abutment protrusion prior to the insertion injection step.

The hybrid healing zone of the present invention is formed of a polymer resin material having a low light reflectance of the abutment protrusion exposed outside the gum, and thus the hybrid healing zone has three-dimensional scanning (scanning) inside the oral cavity without applying a gloss removal liquid or applying a scan cap. ), You can get a clear image with no errors like smearing. Also, in the case of impression taking instead of 3D scanning, instead of removing the hybrid healing abutment from the fixture and mounting the impression coping to the fixture, an impression cap is mounted on the abutment projection to obtain the impression. can do. That is, when the hybrid healing abutment of the present invention is fastened to the fixture, the hybrid healing abutment is not removed from the fixture and is held in a fixed state until the permanent prosthesis, ie, the crown and the fixing abutment supporting the fastener, is fastened to the fixture. Damage and deformation of the alveolar bone and pain during the procedure are suppressed, and the duration of the dental implant procedure is shortened.

In addition, since the abutment protrusion is formed of a polymer resin material having a greater elasticity than the metal, even if the abutment cap is formed of a polymer resin material having the same or similar elastic properties as that of the abutment protrusion, the protection cap is formed. It is elastically in close contact with the abutment protrusion and is not easily separated from the hybrid healing abutment. In addition, even if a crown formed of a polymer resin material having the same or similar elastic properties as that of the protective cap is placed on the protective cap without a dental adhesive, the crown is elastically in close contact with the protective cap. It is not easily separated from the hybrid healing abutment and the protective cap. Therefore, the inconvenience and embarrassment of daily life during the dental implant treatment is prevented.

In addition, even if the hybrid healing zone of the present invention is not covered with a protective cap formed of a polymer resin material is not exposed to the metal luster but the abutment protrusions of the color and texture similar to the teeth, it is not easily visible to others. Thus, the psychological burden is alleviated when the patient encounters another person during the treatment of the dental implant.

Hereinafter, with reference to the accompanying drawings will be described in detail a hybrid healing abutment and its preparation method according to an embodiment of the present invention. Terminology used herein is a term used to properly express a preferred embodiment of the present invention, which may vary depending on the intention of a user or an operator or customs in the field to which the present invention belongs. Therefore, the definitions of the terms should be made based on the contents throughout the specification.

1 is a perspective view of a hybrid healing abutment according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a fixed fastening of the hybrid healing abutment of Figure 1, the hybrid healing abutment of Figure 1 to II-II It is a figure cut along the figure. 1 and 2 together, the hybrid healing abutment 20 according to an embodiment of the present invention is a screw 10 to a fixture 5 fixed to the alveolar bone during a dental implant procedure. It is a member fastened and fixed by).

In detail, the fixture 5 has a male screw pattern 6 formed on an outer circumferential surface thereof, and a female screw pattern (female screw pattern) on an inner circumferential surface of a screw hole 9 having an open upper side. 7) is formed, it is placed in the alveolar bone (not shown) of the patient. The hybrid healing abutment 20 is fastened and fixed to the fixture 5 so that the gums are esthetically rebuilt in the process of rebuilding the damaged gum (not shown) in order to insert the fixture 5.

The hybrid healing abutment 20 is a base 21 fitted to the fixture 5 and abutment protrusions 30 which are integrally bonded to the base 21 and protrude in a direction away from the fixture 5. ). The base 21 is formed of a metal material, and preferably, may be formed of pure titanium (Ti) or a titanium alloy having excellent biocompatibility. The base 21 has a link portion 22 having a polygonal cross section, such as a hexagon and an octagon, and an inner tube portion which protrudes in a direction away from the fixture 5, that is, in a positive Z-axis direction. 23 is provided. The base 21 is formed with a screw through hole 27 extending in parallel with the Z axis.

A link part mounting groove 8 is formed in the periphery of the opening of the screw hole 9 of the fixture 5 in which the link part 22 is seated. The link portion mounting groove 8 is formed to have a cross section corresponding to the polygonal cross-sectional shape of the link portion 22. Thus, when the link portion 22 is seated in the link portion seating groove 8, the hybrid healing abutment 20 cannot be inadvertently rotated about an axis parallel to the Z axis.

The abutment protrusions 30 are formed of a polymer resin material. Preferably, it may be formed of polyetheretherketone (PEEK) or polyetherketoneketone (PEKK) having excellent biocompatibility and having a light reflectance smaller than that of a metal. Since PEEK and PEKK have excellent abrasion resistance and impact resistance, the hybrid healing abutment 20 may exhibit durability as much as the healing abutment formed entirely of a metal material.

The abutment protrusion 30 is connected to the base 21 and extends in parallel with the direction of the positive Z axis (+) to form a gum forming guide portion 31, and the end portion 33 is connected to the gum forming guide portion 31. ). The gum forming guide part 31 is a part for inducing the gum 103 to grow as intended in the process of rebuilding the gum. The abutment protrusions 30 are formed with screw holes 38 extending in parallel with the Z axis. The abutment projections 30 and the screw through holes 38 and 27 of the base 21 are aligned in a straight line parallel to the Z axis so that the screw 10 penetrates. In addition, when the link portion 22 is seated in the link portion seating groove 8, the screw holes 38 and 27 of the abutment protrusion 30 and the base 21 are screw holes 9 of the fixture 5. Aligned with.

 The distal end portion 33 has a pair of directional grooves 34 disposed at intervals of 180 ° with respect to the screw aperture 38 and 180 ° with respect to the screw aperture 38. A pair of incisions 36 is formed. The pair of direction indicating grooves 34 are recessed grooves formed differently from the periphery of the distal end portion 33, and the link portion 22 is fitted into the link portion seating groove 8 of the fixture 5 to be seated therein. When it is possible to know the installation direction of the hybrid healing abutment (20).

The pair of incisions 36 is a stepped surface that is differentiated from the periphery of the distal end 33. When the protective cap 40 (see FIG. 3) or the impression cap 50 (see FIG. 4), which will be described later, is mounted to cover the abutment protrusion 30, the protective cap 40 is caught by the pair of cutouts 36. 40 or impression cap 50 do not rotate unintentionally with respect to the abutment protrusion 30. On the other hand, when the abutment cap 30 is not covered with, for example, the protective cap 40, the impression cap 50, and the like, and the distal end 33 is exposed, the pair of incisions 36 are As with the pair of directional grooves 34, the installation direction of the hybrid healing zone column 20 can be known.

On the outer circumferential surface of the distal end 33, a separation prevention groove 35 is formed so that the protective cap 40 or the impression cap 50 is covered with the abutment protrusion 30 and is not inadvertently removed. In other words, a separation prevention elastic protrusion (not shown) protruding from the inner circumferential surface of the healing abutment mounting grooves 41 and 51 (see FIGS. 3 and 4) of the protective cap 40 and the impression cap 50 prevents the separation. The protective cap 40 and the impression cap 50 are not detached from the distal end portion 33 by being inserted into the groove 35 and elastically adhered to the groove 35.

The screw 10 for fastening the hybrid healing zone 20 to the fixture 5 has a screw column 13 extending in parallel with the Z axis and a screw head formed to have an extended diameter at an upper end of the screw column 13. (11) is provided. The male screw pattern 15 is formed on the outer peripheral surface of the end portion of the screw pillar 13. The fastening screw 10 is inserted into the screw through holes 38 and 27 through the abutment projections 30 with the link portion 22 of the base 21 fitted into the link portion seating groove 8 of the fixture 5. When rotated in one direction, the male screw pattern 15 at the end of the screw column 13 penetrating the base 21 is fastened to the female screw pattern 7 of the fixture screw hole 9. The screw 10 is oriented in one direction until the screw head 11 is caught by the inner diameter reduction step surface 39 formed in the inner circumferential surface of the abutment protrusion 30 and the screw 10 can no longer be rotated. With continued rotation, the hybrid healing abutment 20 is firmly fixed to the fixture 5 by the screw 10.

The hybrid healing abutment 20 helps the alveolar bones and gums that are cut and wounded for extraction of the extraction and fixture 5 to be appropriately regenerated and recovered to install a prosthesis, ie a fixed abutment and crown. In addition, when the prosthesis is manufactured based on image data by three-dimensional scanning the inside of the oral cavity, even if the hybrid healing abutment 20 fixed to the fixture 5 is scanned as it is, bleeding due to light reflection Or no image error such as blur occurs.

In other words, when the healing abutment formed entirely of a metallic material is scanned as it is due to the light reflection property of the metal, there is a bleeding or blurring portion in the scanning image, which makes it difficult to obtain clear scanning image data. Therefore, in order to prevent the image error, a gloss removal liquid is applied to the surface of the healing zone, or a scan cap formed of a non-gloss polymer resin is put on and three-dimensional scanning is performed.

However, in the hybrid healing abutment 20 according to the embodiment of the present invention, the abutment protrusion 30 is formed of a polymer resin material so that the light reflectance on the surface of the abutment protrusion 30 is smaller than the light reflectance on the surface of the base 21. Thus, even if the gloss removal liquid or the scan cap is not applied, an image obtained by scanning the inside of the oral cavity with the hybrid healing abutment 20 fastened to the fixture 5 may be swept or blurred due to light reflection. There is no image error. Thus, the intraoral scanning operation is facilitated, the working cost is reduced, and the pain and psychological burden of the patient is also reduced.

FIG. 3 is a cross-sectional view illustrating a protective cap and a crown mounted on the hybrid healing zone column of FIG. 2. Referring to FIG. 3, foreign substances may be caught due to food intake in the screw hole 38 of the hybrid healing zone 20 fastened to the fixture 5 to cause tooth decay, periodontal disease, or bad breath. In order to prevent this, the abutment projection 30 of the hybrid healing abutment 20 closes the screw hole 38 and a protective cap 40 surrounding the distal end 33 is detachably covered and mounted thereon. Can be.

The protective cap 40 is formed of a polymer resin material, and preferably may be formed of PEEK or PEKK material like the abutment protrusions 30. The protective cap 40 is provided with a healing abutment mounting groove 41 which is dug to correspond to the shape of the distal end 33 so that the distal end 33 of the abutment protrusion 30 is in close contact. Therefore, the implant operator, that is, the dentist may mount the protective cap 40 on the abutment protrusion 30 so that the distal end portion 33 is inserted into the healing abutment mounting groove 41. When the protective cap 40 is mounted on the abutment protrusion 30 in this manner, the protection cap 40 and the abutment protrusion 30 are elastically in close contact with each other. The abutment protrusion 30 and the protective cap 40 are both formed of a polymer resin material, and thus, the elastic adhesive force is greater and the static friction force is greater than that of the healing abutment which is a metal material and the protection cap 40 which is a polymer resin material.

In addition, a separation prevention elastic protrusion (not shown) protruding from the inner circumferential surface of the healing abutment mounting groove 41 of the protective cap 40 is inserted into the separation prevention groove 35 of the abutment protrusion 30 as described above. As a result, the protective cap 40 does not randomly fall out of the abutment protrusion 30, and a pair of cutaways 36 of the abutment protrusion 30 are mounted on the abutment protrusion 30 to rotate arbitrarily. Prevent it. Therefore, the protective cap 40 is not easily detached from the abutment protrusion 30 while the patient ingests food or opens and closes the mouth.

The protective cap 40 alone may prevent foreign matters from being caught in the hybrid healing abutment 20, but chewing food is incomplete and may sound pronounced when speaking. In particular, teeth other than hind and wisdom teeth, ie, central incisor, lateral incisor, canine, and incisor molar, are visible when the mouth is open, which is why the patient during dental implant treatment avoids interpersonal contact. Therefore, the crown 45 of the tooth shape can be detachably mounted on the protective cap 40 covered by the abutment protrusion 30. The crown 45 is a temporary crown that covers the protective cap 40 without applying dental adhesive.

The temporary crown 45 is formed of a polymer resin material, and preferably may be formed of a PEEK or PEKK material, like the abutment protrusions 30 and the protective cap 40. The temporary crown 45 is formed with a protective cap mounting groove 46 which is dug to correspond to the outer surface shape of the protective cap 40 so that the outer surface of the protective cap 40 can be inserted in close contact. Therefore, an implant operator, that is, a dentist, may mount the temporary crown 45 on the protective cap 40 so that the protective cap 40 is inserted into the protective cap mounting groove 46. When the temporary crown 45 is mounted on the protective cap 40 in this manner, the temporary crown 45 and the protective cap 40 are elastically in close contact with each other, and the protective cap 40 and the abutment protrusion 30 are elastically in close contact with each other. The temporary crown 45 is not easily removed from the protective cap 40 during the ingestion of food or the opening and closing of the mouth, and the protective cap 40 is also not easily removed from the abutment protrusion 30.

The protective cap 40 and the temporary crown 45 are separated from the abutment protrusion 30 when performing the impression taking process using the above-described three-dimensional scanning or impression cap 50 (see FIG. 4), and the 3 When the dimensional scanning or impression taking process is finished, the abutment protrusion 30 may be reapplied. In addition, the protective cap 40 and the temporary crown 45 are the hybrid healing abutment 20 when the hybrid healing abutment 20 is replaced by a permanent prosthesis, that is, a fixing abutment and a crown fixed thereto by a dental adhesive. ) Can be removed in the oral cavity.

FIG. 4 is a cross-sectional view illustrating an impression cap mounted on the hybrid healing zone column of FIG. 2. As described above, three-dimensional scanning of the inside of the oral cavity with the hybrid healing abutment 20 fastened to the fixture 5 as it is may be performed to obtain data on the internal shape of the patient's oral cavity for prosthesis production. Data on the internal shape of the patient's mouth can also be obtained. Referring to FIG. 4, the impression cap 50 is mounted on the abutment projection 30 while the hybrid healing abutment 20 is fastened to the fixture 5 to obtain the impression. On the other hand, the shape of the impression cap 50 mounted on the abutment protrusion 40 is not limited to the shape shown in FIG.

The impression cap 50 is formed of a polymer resin material. The impression cap 45 is provided with a healing abutment mounting groove 51 which is dug to correspond to the shape of the distal end 33 so that the distal end 33 of the abutment protrusion 30 may be inserted in close contact. Therefore, the implant operator, ie, the dentist, may mount the impression cap 50 on the abutment protrusion 30 so that the distal end portion 33 is inserted into the healing abutment mounting groove 51. When the impression cap 50 is mounted on the abutment protrusion 30 in this manner, the impression cap 50 and the abutment protrusion 30 are elastically in close contact with each other.

In addition, the separation prevention elastic protrusion (not shown) protruding from the inner circumferential surface of the healing abutment mounting groove 51 of the impression 50 as described above is inserted into the separation prevention groove 35 of the abutment protrusion 30 and elastically adhered thereto. The impression cap 50 does not easily fall out of the abutment protrusion 30, and the pair of incision surfaces 36 of the abutment protrusion 50 prevent the impression 50 mounted on the abutment protrusion 30 from rotating arbitrarily. .

Meanwhile, the hybrid healing abutment 20 described above with reference to FIGS. 1 to 4 has two heterogeneous materials, that is, a portion 21 made of a metal material and a portion 30 made of a polymer resin material. It is named as a 'hybrid' healing abortion, but can also be called a 'hybrid' healing abortion in terms of use. In other words, the abutment of the hybrid healing abutment may be secured with a permanent crown that replaces the patient's removed tooth. The permanent crown may be adhesively fixed to the abutment protrusion 30 via a dental adhesive. In other words, the hybrid healing abutment of the present invention may be used not only for the traditional healing abutment but also for a fixed abutment.

5 is a view for explaining the insertion injection step of the hybrid healing abutment manufacturing method according to an embodiment of the present invention. 2 and 5 together, the hybrid healing abutment manufacturing method according to an embodiment of the present invention, the base forming step (S10), the adhesive coating step (S20), the insertion injection step (S30), the finishing step (S40) is provided.
