Description

Barrier film for dental implants

technical field

The present invention relates to a barrier film, and more particularly relates to a barrier film for dental implants.

Background technique

Dental implant surgery basically cuts the patient's gums open, inserts an implant post into the gingival bone (called "alveolar bone"), and attaches artificial teeth (crowns) to the implant post. To be done.

In order to perform implant surgery, the alveolar bone into which the fixture is implanted needs sufficient length and width. Bones are more often absorbed or disappear by other tissues. At this time, induced bone regeneration (also referred to as "osteogenic regeneration") is required, and bone, unlike other tissues, uniquely has the potential to fully return to the body structure. However, in order for the bone to regenerate into the correct shape, basic conditions are required, which are mechanical stability and abundant blood supply.

The biological requirements for osteoinductive regeneration include blood flow supply, stabilization, osteoblasts, limited space, space maintenance, and wound coverage, for which various surgical procedures are performed. If proper pressure is applied to the bone graft material, it can improve compactness and help bone formation.

In particular, barrier films are used for stabilization and confined spaces. The barrier membrane protects the blood cake, prevents soft tissue cells from moving to the bone defect, and has the function of positioning bone cells.

detailed description

Next, preferred embodiments of the barrier film for dental implants according to the present invention will be described in detail with reference to the accompanying drawings. The drawings show exemplary aspects of the present invention, and are provided for explaining the present invention in more detail, and do not limit the technical scope of the present invention thereby.

Dental implant mechanism generally refers to the artificial tooth structure formed by implanting artificial tooth roots, that is, fixing devices, on the part of the teeth that are partially or entirely missing, adhering to the alveolar bone, and fixing the prostheses on the artificial tooth roots. The term dental implant can be used in a broad sense as an inclusive concept including this dental operation method, and in a narrow sense it can be used in the same meaning as a fixture. In this specification, a dental implant or a dental implant structure can be mainly used as a general artificial tooth structure.

Fig. 1 is a schematic diagram showing implantation of a dental implant mechanism. Fig. 2 is a sectional view showing a section of the planting mechanism.

Referring to FIG. 1 and FIG. 2 , the dental implant mechanism may include: a bone-tissue joint part 10 , a crown connection part 20 , an abutment 30 and a crown 40 . Here, the bone tissue combining part 10 and the crown connecting part 20 are referred to as the implant post 1 .

The lower end of the crown connecting portion 20 is connected to the bone-tissue bonding portion 10 , and the abutment 30 can be bonded to the upper end. The tooth crown connection part 20 is preferably integrally formed with the bone tissue joint part 10 .

The dental implant has an integral type in which the crown connection part 20 and the abutment 30 are integrally formed and a detachable separable type. The separate type can be classified into an internal type and an external type according to the connection structure of the crown connection part 20 and the abutment 30 . Fig. 1 shows an external type, but embodiments according to the present invention can be applied to all internal and external types.

The outer peripheral surface of the crown connection part 20 can be protrudingly formed to be inserted into the abutment 30, and can be formed in various forms. For example, the crown connection part 20 may be in the shape of a polygonal column. A groove may be formed inside the abutment 30 for inserting the crown connecting portion 20 , and the form of the groove may be formed to correspond to the shape of the outer surface of the crown connecting portion 20 . Specifically, when the crown connecting portion 20 is a polygonal column, the groove inside the abutment 30 may form a polygonal column shape. At this time, as described above, the crown connection part 20 is inserted into the abutment 30, and the outer surface of the crown connection part 20 and the inner surface of the abutment 30 correspond to each other, so that after the crown connection part 20 is combined with the abutment 30, the Prevent the crown 40 from rotating or misaligning its position.

On the upper surface of the crown connecting portion 20 , a nut portion 22 for crown bonding (hereinafter referred to as “nut portion”) may be formed in a recess toward the bone tissue bonding portion 10 . The abutment 30 may have an insertion hole 30 b into which the crown coupling bolt 50 is inserted. The crown fixing bolt 50 couples and fixes at least one of the abutment 30 and the crown connecting portion 20 , thereby firmly fixing the crown 40 .

The crown 40 forms the appearance of an artificial tooth. Crown 40 may be referred to as a crown, artificial tooth, or the like. In this case, the crown 40 is formed after the abutment 30 , so it can be arranged on the crown connection part 20 .

The planting stake 1 can be separately referred to as a main body and a head. The main body of the implant post 1 refers to the part inserted into the dental bone; the head of the implant post 1 refers to the upper part of the main body, which is the part combined with the tooth crown. The head of most of the planting posts 1 can be understood as the same part as the crown connection part 20 .

So far, FIGS. 1 and 2 have shown a screw-holding type method in which a crown (crown) is fixed to the implant post 1 (or fixing device) or the abutment 30 by screws, but is not limited thereto. Although not shown in this specification, the abutment 30 can be screwed to the fixing device, the crown made separately can be placed on the fixed abutment 30, and the crown and the abutment 30 can be cemented together with dental cement. A cement-retaining approach can also be applied to embodiments according to the present invention.

FIG. 3 is a cross-sectional view showing a dental implant barrier film 121 covering a bone graft material 60 (also referred to as "bone graft material").

Referring to FIG. 3 , during the implant operation, the patient's gingiva is first cut open, and the implant post 1 is inserted into the alveolar bone B therein. If the alveolar bone B is insufficient, osteoinductive regeneration can be performed by implanting angular artificial bone in the insufficient alveolar bone B or inserting powdered artificial bone (bone graft material 60) to enlarge the alveolar bone B (Guided Bone Regeneration; GBR). After filling the bone graft material 60 , in order to maintain the necessary shape of the bone graft material 60 , prevent soft tissue from intervening, and induce bone tissue inflow, a barrier film 121 for dental implant can be used.

The dental implant barrier film 121 as described above can be formed in various shapes using various materials. The dental implant barrier film 121 as described above may include: an absorbable barrier film 121A that covers the implant post 1 and the bone graft material 60 on the alveolar bone B and is absorbed by the bone tissue after osteoinductive regeneration; At least one of the non-absorbent barrier films 121B that maintains the shape of the absorbent barrier film 121A is used on the outer side of the absorbent barrier film 121A.

The absorptive barrier film 121A as described above is a product made of a biodegradable substance, and it is made to be decomposed and absorbed by tissues after performing a barrier function for a certain period of time. Divided into cruciform and non-cruciform, etc., it will be absorbed within a minimum of 2 weeks to a maximum of 54 weeks, and no additional removal surgery is required. Even if the absorbent barrier film 121A is exposed to the outside or damaged, it performs the function of a barrier, so that the risk of infection is relatively low.

Absorbable barrier film 121A mainly made of collagen, polylactic acid, polylactic acid, etc. does not require 2 operations, prevents the movement of epithelial cells, and creates a space to induce Selective cell proliferation and bone regeneration. In addition, the absorbent barrier film 121A has elasticity, so it is used to block the mechanical pressure applied on the wound.

For example, the absorptive barrier film 121A can be represented by collagen, which is generally produced by processing collagen obtained from animal tendon (Tendon) or the like. Such an absorbable barrier film 121A slightly delays bone regeneration compared to a nonabsorbable barrier film, has fewer side effects than the nonabsorbable barrier film 121B, and is excellent in safety.

However, when only the absorbent barrier film 121A is used alone, compared with the non-absorbent barrier film 121B, the space securing ability is slightly lowered, and there is a disadvantage that the effect as a support is small.

Compared with this, the advantage of using the non-absorbing barrier film 121B of a metal material such as titanium is that it functions as a support while maintaining its shape, and it is easy to secure a period required for cell proliferation.

The implant barrier film 121 may be formed of bone components in addition to being formed as described above.

Next, the implant barrier film 121 formed of bone components will be described in detail.

FIG. 4 is a perspective view showing a barrier film 200 for a dental implant according to an embodiment of the present invention. FIG. 5 is a perspective view showing a heterogeneous bone formed with the dental implant barrier film 200 shown in FIG. 4 .

Referring to FIGS. 4 and 5 , the barrier films 200 and 200A for dental implants may include main body parts 210 and 210A as bone components. The bone component may be one or a combination of allogeneic bone, synthetic bone, and heterogeneous bone.

In particular, allografts represent human bones. The main body parts 210 and 210A made of the same type of bone may be produced by cutting a part of the bone of the patient himself or another person. For example, the main body parts 210 and 210A are formed by processing a part of the alveolar bone to which the implant post (not shown) is to be attached in a shell form.

The above-mentioned homogeneous bone can be used by freezing or freeze-drying the implant material, deliming and freeze-drying, and deantigenizing it in the form of irradiation. Although the period required for bone formation is long and the amount of newly generated bone is small, However, it has the advantage of being able to use the required amount at any time without causing additional surgical sites.

As the type of this homogeneous bone, there are Demineralized frozen dried bone allografts (DFDBA), Freeze dried bone allografts (FDBA), and Irradiated cancellous bone (ICB). ).

The heterogeneous bone means a bone of an animal such as a cow or a pig. It is an implant material that expects bone conduction ability by reducing the immune response through such various processes. It has the advantages of not needing to make additional surgical sites and can fully use the required amount, but it takes a long time to absorb and replace. relationship, the current trend is to favor understanding as the basis of osteoconduction over osteoinduction. The types of this xenograft bone include Bio-Oss, ABM/P-15 and BioCeraTM.

In addition, synthetic bone means artificially formed bone. Synthetic bone is formed by mixing animal bone, that is, xenogeneic bone, with other materials, or it can be formed with a material that can replace the bone component. This kind of synthetic bone is not actual bone but artificially made bone, so compared with other bone grafting materials, the quality is the lowest, and the period required for bone formation is long, but it has the advantage of being cheap. Synthetic bone with or without pores (non-porous hydroxyapatite (HA), hydroxyapatite cement (hydroxyapatite cement), porous hydroxyapatite (porous hydroxyapatite), β-tricalcium phosphate (beta tricalcium) phosphate), polymethyl methacrylate (polymethlymethacrylate (PMMA)) and hydroxyethyl methacrylate polymer (hydroxyet-hylmethacrylate (HEMA) polymer), and bioactive glass (bioactive glass), etc. HA and PMMA and HEMA Polymers are nonabsorbent, tricalcium phosphate and bioactive glass are absorbent. Types of this synthetic bone include third calcium phosphate, hard tissue media polymers, and living vitreous ceramic membranes etc. In the following, for the convenience of description, the main body portion 210, 210A will be described in detail centering on the case where the main body portion 210, 210A is formed of a heterogeneous bone.

On the other hand, the thickness of the above-mentioned main body parts 210 and 210A is preferably in the form of a thin film that can closely cover the bone graft material (not shown) added to the missing part of the alveolar bone (not shown).

The main body parts 210 and 210A as described above can be formed in various forms. For example, the body portion 210, 210A may be formed in a streamlined shape or have a curvature. In addition, the main body portion 210, 210A may be formed in a hemispherical shape, a spherical shape, an elliptical shape, or the like. The main body parts 210 and 210A may be formed in a flat plate form other than the above-mentioned case. At this time, the main body parts 210 and 210A can be formed in various shapes in consideration of the form of the above-mentioned alveolar bone, the arrangement form of adjacent teeth, and the like. However, in the following, for convenience of description, a case in which a part of the main body portions 210 and 210A are bent will be described in detail.

Specifically, the main body portion 210 of FIG. 4( a ) may include a cover portion 211 and a first bent portion 212 bent from the cover portion 211 . In addition, the main body part 211 may include a second curved part 213 formed by bending from the main body part 211 and disposed so as to face the first curved part 212 . At this time, the cover part 211 can cover the upper part of the bone graft material on which the implant post is installed, and the first curved part 211 can cover the side part of the bone graft material. In addition, the second bending portion 213 can be hung on the above-mentioned normal alveolar bone.

That is, the first and second curved portions 212 and 213 may be arranged in a direction perpendicular to the direction of the tooth row. Specifically, one of the first and second curved portions 212, 213 may be arranged in the labial direction centered on the above-mentioned alveolar bone, and the other of the first and second curved portions 212, 213 may be centered on the above-mentioned alveolar bone. Configured in the direction of the tongue. At this time, the above-mentioned alveolar bone and the above-mentioned bone grafting material can be arranged in the space between the first and second bending parts 212, 213, and the first and second bending parts 212, 213 can prevent the above-mentioned alveolar bone and the above-mentioned bone grafting. The position of the material is staggered.

On the other hand, the main body portion 210A of FIG. 4( b ) may include a cover portion 211A and a first bent portion 212A. In this case, the lid portion 211A and the first bent portion 212A may be the same as or similar to the lid portion 211A and the first bent portion 212A in FIG.

At least one of the above-described cover portion 211A and first curved portion 212A may include a fixing member coupling portion 219A. A fixing member (not shown) in the form of a screw or a post can connect the barrier film for dental implant 200A, especially a certain bending portion (for example, the first bending portion 212A) of the barrier film to the alveolar bone through the fixing member connecting portion 219A. The fixing member coupling portion 219A may be in the form of a hole passing through the main body portion 210A.

The method of processing the barrier films 200 and 200A for dental implants as described above from the heterogeneous bone 70 is as follows. Specifically, the barrier films 200 and 200A for dental implants can be processed from the spongy tissue 74 or the compact bone 76 , and can be processed to include both the compact bone 76 and the spongy tissue 74 . For the convenience of description, the following description will focus on the case where the barrier films 200 , 200A for dental implants are processed from the compact bone 76 .

Specifically, the dental implant barrier membranes 200 and 200A can be extracted from the compact bone 76 located on the outer contour of the xenograft bone 70 by processing it into a necessary shape. At this time, the heterogeneous bone 70 is composed of blood vessels 72 , spongy tissue 74 , and compact bone 76 from the center to the outside. The bone density of the dense bone 76 is higher than that of other parts, so the barrier films 200 and 200A for dental implants can be processed into a necessary shape at the dense bone 76 and extracted.

The dental implant barrier membranes 200 and 200A can be extracted by processing the heterogeneous bone 70 into a usable form through computer-aided design/computer-aided manufacturing (CAD/CAM) or 3D drilling machine. At this time, computer-aided design/computer-aided manufacturing (CAD/CAM) or a 3D printer can be designed to extract at least a part of the curved barrier film 200, 200A at the dense bone 76 located on the outer contour of the heterogeneous bone 70.

As mentioned above, when the implant barrier membrane 200, 200A is processed with the heterogeneous bone 70, side effects of immune reaction and infection may occur. Here, the surfaces of the implant barrier films 200 and 200A may be subjected to immune reaction removal treatment or infection blocking treatment. Such treatment may be subjected to post-treatments such as low-temperature or high-temperature treatment, freeze-drying, treatment with chemicals, and sterilization treatment so as not to be harmful to the human body.

On the other hand, the implant barrier films 200 and 200A may be processed by compression-molding the heterogeneous bone 70 or synthetic bone components in addition to the above-mentioned cases. Not only that, the barrier film can be processed into various forms.

The barrier films 200 and 200A for dental implants may include protrusions 220 and 220A formed on the body parts 210 and 210A. At this time, the protruding parts 220 and 220A may be formed on the cover parts 211 and 211A toward the above-mentioned planting piles. The protrusions 220 and 220A will be described in detail below.

FIG. 15 is a perspective view showing a dental implant barrier film according to another embodiment of the present invention, and FIG. 16 is a plan view showing a through-hole shape of the dental implant barrier film according to an embodiment of the present invention.

Referring to FIG. 15 , the dental implant barrier film 100' has a through hole 220' instead of the protrusion 200 of the dental implant barrier film 100 shown in FIG. 4( a ).

The through hole 220' allows the cap screw (or treatment abutment) to pass through the implant post, thereby fixing the implant barrier film 200, 200A to the implant post. As shown in FIG. 15, the through hole may be circular. However, the through holes are not limited thereto, and may have various shapes. For example, as shown in Fig. 16, it may be a combination of a circular hole 220'-1 and a strip-shaped cutout 220'-2. The strip-shaped cut 220'-2 can provide flexibility to allow the portion of the implant post larger than the diameter of the circular hole 220'-1 to pass through the implant barrier membrane. The protrusions included in the dental implant barrier films of the examples described below may be replaced with through holes.

Other than that, the constituent elements are the same as those in FIG. 4( a ), so the description of the elements denoted by the same symbols will be omitted.

Fig. 6 is a cross-sectional view showing the barrier film for a dental implant shown in Fig. 4(a) and a portion where an implant post operation is performed.

Referring to FIG. 6 , during the implant surgery, the implant post 1 can be planted on the alveolar bone B after the gingiva (not shown) is cut. At this time, the planting stake 1 may include an internal type planting stake or an external type planting stake. For the convenience of description, the following will focus on the case where the planting stake 1 includes the internal type planting stake in detail.

As described above, when the implant post 1 is implanted in the alveolar bone B, the alveolar bone B may be partially depressed or missing depending on the patient's condition. If the planting post 1 is inserted in such a missing part, the retaining force of the post will be reduced, causing problems in the cosmetic prosthesis, and adversely affecting the life of the post.

In order to prevent the above problems, a part of the alveolar bone B that is depressed or missing may be filled with a bone graft material 60 . At this time, it takes a certain period of time for the bone graft material 60 to be replaced by bone. As described above, before the bone graft material 60 is replaced by the alveolar bone B, the implant barrier film 200 may be provided on a part of the alveolar bone B and the outer surface of the bone graft material 60 to maintain the shape of the bone graft material 60 .

Specifically, in the case where the implant post 1 is implanted in the alveolar bone B as described above, the bone-tissue coupling part 10 can be inserted into the alveolar bone B. As shown in FIG. At this time, at least a part of the crown connection portion 20 may protrude to the outside of the alveolar bone B. As shown in FIG.

After the operation as described above is completed, it takes a certain amount of time for the implant post 1 to be positioned.

On the other hand, after the above-mentioned implant post 1 is installed on the alveolar bone B, the bone graft material 60 can be inserted into the missing part of the alveolar bone B. At this time, the implant barrier film 200 described above may be provided on the portion where the bone graft material 60 is inserted to prevent the bone graft material 60 from detaching or deforming.

Specifically, the barrier film 200 for dental implant can be configured to cover the upper surface of the implant post 1 and a part of the bone graft material 60 . At this time, the cover part 211 is arranged on the upper surface of the implant post 1 as described above, and the first curved part 212 can be arranged so as to be partially in contact with the bone graft material 60 . In addition, the second curved portion 213 is in contact with a part of the alveolar bone B in the direction opposite to the first curved portion 212 . At this time, the positions of the first bending portion 212 and the second bending portion 213 are not limited to the above, and may be reversed.

On the other hand, when the main body portion 210 is provided as described above, the protruding portion 220 can be inserted into the above-mentioned nut portion of the crown connection portion 220 . Alternatively, when the temporary bolt 150 is provided on the above-mentioned nut portion, the protruding portion 220 may be inserted into the recessed portion 153 of the temporary bolt 150 . Hereinafter, for convenience of description, a case in which the temporary bolt 150 is provided on the crown connection portion 20 and the protruding portion 220 is inserted into the recessed portion 153 will be described in detail.

The protruding portion 220 as described above may be interference-fitted in the recessed portion 153 . In this case, the depression 153 may be in the shape of a polygonal prism, cylinder, cone, or hemisphere whose cross-section is perpendicular to the longitudinal direction of the depression 153 and is a regular polygon such as a regular hexagon. In addition, the protruding part 220 may be formed in the shape of a cylinder, a cone, a hemisphere, or a regular polygon such as a regular hexagon in section. At this time, the shapes of the protruding part 220 and the recessed part 153 may be formed differently from each other. For example, when the recessed part 153 is formed in the form of a polygonal column, the cross section of the protruding part 220 may be formed in a cylindrical, conical, or hemispherical shape. Conversely, when the depression 153 is formed in a cylindrical, conical, or hemispherical shape, the protruding portion 220 may be formed in a regular polygonal column shape. Hereinafter, for convenience of description, a case in which the depressed portion 153 is formed in a regular polygonal prism shape and the protruding portion 220 is formed in a cylindrical shape will be described in detail.

As mentioned above, in the case of the interference fit between the protrusion 220 and the recess 153, a space may be formed between the outer surface of the protrusion 220 and the inner surface of the recess 153, therefore, the shape of the protrusion 220 and the recess 153 are different, Thereby, the protruding portion 220 can be smoothly removed from the recessed portion 153 .

In order for the protruding portion 220 to fit properly in the recessed portion 153, the diameter of a certain section in the protruding portion 220 may be greater than the shortest distance between the opposite inner ends based on the center of the recessed portion 153 cross-section, and smaller than the diameter of the recessed portion. The center of the section 153 is the longest separation distance based on the opposite inner ends.

On the other hand, when the barrier film for dental implant 200 is rotated in a state where the protrusion 220 is interference-fitted into the recess 153 of the temporary bolt 150 , the barrier film for dental implant 200 can perform relative circular motion with respect to the temporary bolt 150 . . Therefore, after the position and direction of the barrier film 200 for dental implant are determined during the operation, the barrier film 200 for dental implant can be vertically installed on the implant post 1, and if there is an error in the direction, the barrier film for dental implant can be simply rotated The action of the membrane 200 easily corrects its errors.

The protruding portion 220 as described above may be formed of the same material as that of the main body portion 210 or a similar material. For example, the protrusion 220 may be formed of at least one of homogeneous bone, heterogeneous bone, and synthetic bone. At this time, when the protruding part 220 is formed into the main body part 210 , it may be integrally formed, or may be separately manufactured and connected to the main body part 210 .

In addition, the protruding part 220 may be formed of a completely different material from that of the main body part 210 . For example, the protruding part 220 may be formed of a metal material such as titanium or a plastic material such as resin or engineering plastic. The protrusions can also be formed by mixing metal and plastic materials. At this time, the protruding part 220 may be separately manufactured from the main body part 210 and provided on the main body part 210 . Specifically, after the protruding portion 220 is formed of metal or plastic material, a part thereof is inserted into the main body 210 to be combined or fixed on the main body 210 by an adhesive substance. Hereinafter, for convenience of description, a case in which the protruding portion 220 is integrally formed with the main body portion 210 will be described in detail.

The bone graft material 60 may be completely adhered to the alveolar bone B after time elapses after disposing the protrusion 220 to the recess 153 of the temporary bolt 150 as described above.

Therefore, the barrier film 200 for a dental implant maintains the shape of the bone graft material 60, thereby helping the bone graft material 60 to be safely placed on the alveolar bone B. FIG. Furthermore, since the barrier film 200 for dental implant is formed of bone components, it can help the bone graft material 60 to be placed on the alveolar bone B in a short time.

FIG. 7 is a cross-sectional view showing the dental implant barrier film 200A shown in FIG. 4( b ) and a portion where the implant post 1 has been operated.
