Description

{Guided Bone and Tissue Regeneration Membrane}

The present invention relates to a shielding film for alveolar bone regeneration, and more particularly to a shielding film using biodegradable fibers.

When the bone is detached from the alveolar bone due to an accident or the like, bone powder is filled into the bone detachment portion and the alveolar bone shielding layer is connected to the artificial tooth root to regenerate the alveolar bone.

Fig. 1 shows an example of such an operation. When the bone detachment portion 300 is formed in the alveolar bone 100, the gum layer 200 is peeled off and then the bone detaching portion 300 is filled with the bone powder for regenerating the bone. At this time, it is advantageous for bone regeneration to be shielded between the gum layer 200 and the bone detaching part 300. A shielding film provided with a hole through which the artificial root 10 penetrates is used. In the past, titanium was used as a material of the shielding film. However, after the bone regeneration is completed, the shielding film of the titanium material should be removed. Since the gum bed 200 is removed and removed, the procedure of the difficulty is re-performed to increase the operation cost and inconvenience of the patient There were disadvantages.

Korean Patent Nos. 1269127 and 0940074 disclose biodegradable fibrous materials to be applied to the human body and apparatuses for fabricating the supports by adapting them in multiple layers using such materials. The present invention can adopt such a biodegradable fiber material as a main material and can be manufactured using such a support manufacturing apparatus and a lamination method. The entire contents of these two Korean patents are included as part of this specification to the extent that no contrary thereto is expressly recited herein.

It is an object of the present invention to provide a shielding film for regenerating a biodegradable alveolar bone to solve the disadvantages of the prior art, and more particularly, to provide a shielding film for alveolar bone regeneration, which can prevent a problem occurring when a biodegradable material is used .

The shielding film for alveolar bone regeneration according to the present invention comprises a first biodegradable fibrous layer in contact with the bone graft material side, a second biodegradable fibrous layer provided on the first biodegradable fibrous layer and in contact with the gum layer, And a first reinforcing biodegradable fibrous layer provided on the first reinforcing biodegradable fibrous layer.

According to another aspect of the present invention, a shield for alveolar bone regeneration comprises a first biodegradable fibrous layer on the bone graft material side, a second biodegradable fibrous layer provided on the first biodegradable fibrous layer and in contact with the gum layer, And a second reinforcing biodegradable fibrous layer.

The alveolar bone regeneration shielding membrane according to another embodiment of the present invention may include both the first reinforcing biodegradable fiber layer and the second reinforcing biodegradable fiber layer.

The first biodegradable fibrous layer may comprise a plurality of biodegradable fibers arranged side by side with a first spacing.

The second biodegradable fibrous layer may comprise a plurality of biodegradable fibers arranged side by side at a second spacing.

The second biodegradable fibrous layer may include a 2-1 biodegradable fibrous layer laminated on the first biodegradable fibrous layer and a 2-2 biodegradable fibrous layer in contact with the gum layer.

The 2-2 biodegradable fibrous layer may be in contact with at least one of the first reinforcing biodegradable fibrous layer and the second reinforcing biodegradable fibrous layer.

A plurality of second reinforcing biodegradable fibrous layers may be provided along the longitudinal direction.

The shielding film for alveolar bone regeneration according to the present invention may further comprise a biodegradable border layer constituting the rim of the alveolar bone regeneration shielding layer and the first biodegradable fibrous layer and the second biodegradable fibrous layer may extend to the inside of the biodegradable border layer Can be stacked.

The first biodegradable fibrous layer and the second biodegradable fibrous layer may be arranged to cross each other and the second biodegradable fibrous layer may be arranged in a direction crossing the second reinforced biodegradable fibrous layer.

Since the shielding film for alveolar bone regeneration according to the present invention is composed of a biodegradable fibrous layer, it is naturally decomposed after completion of bone regeneration after being inserted between alveolar bone and gingival layer, so that it is unnecessary to remove the shielding film unlike the conventional titanium shielding film . And a reinforcing biodegradable fibrous layer provided along the length of the shielding film and / or the portion where the cap covering the artificial root is provided and / or the thickness of the shielding film, There is an effect of providing a shielding film for alveolar bone regeneration.

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

FIGS. 2 and 3 are perspective views of the alveolar bone regeneration shielding film 50 according to the present invention, and FIGS. 4 and 5 are cross-sectional views of the alveolar bone regeneration shielding film 50 according to the present invention.

The shielding film 50 for alveolar bone regeneration according to the present invention has a border layer 51, a first biodegradable fibrous layer 52 in contact with the bone graft material layer 300 and a second biodegradable fibrous layer 52 in contact with the first biodegradable fibrous layer 52, 1 biodegradable fibrous layer 53 laminated on the second biodegradable fibrous layer 53 and a second biodegradable fibrous layer 54 in contact with the gum layer 200 and a second biodegradable fibrous layer 54 bonded to the artificial root 10, A first reinforcing biodegradable fibrous layer 55 provided at a portion abutting the cap 20 and a second reinforcing biodegradable fibrous layer 56 provided along the length direction.

The number of the fibrous layers laminated on the first biodegradable fibrous layer 52 and contacting the gingival layer 200 is not limited, and one layer or two or more fibrous layers may be laminated. In this specification, the layer laminated on the first biodegradable fibrous layer 52 is collectively referred to as a "second biodegradable fibrous layer" and the second biodegradable fibrous layer may be a plurality of laminated fibrous layers.

The first biodegradable fibrous layer 52 and the second biodegradable fibrous layer 53 and 54 may be laminated so as to extend to the inside of the rim layer 51. [ The first biodegradable fibrous layer 52 and the second biodegradable fibrous layer 53 and 54 may be arranged to cross each other at a predetermined angle as shown in FIGS. The first biodegradable fibrous layer 52 may comprise a plurality of biodegradable fibers arranged side by side at a first interval. The 2-1 biodegradable fibrous layer 53 may comprise a plurality of fibers arranged side by side at a second interval. The second 2-2 biodegradable fibrous layer 54 may also include a plurality of fibers arranged side by side with a third spacing, the second 2-2 biodegradable fibrous layer 54 may include a second reinforced biodegradable May be disposed to intersect the fibrous layer (56). Preferably, the second-biodegradable fibrous layer 54 crosses the second reinforced biodegradable fibrous layer 56 vertically. However, it is not always necessary to vertically intersect, and it is also possible to arrange them at different angles.

As shown in FIG. 1, when the artificial root 10 passes through the alveolar bone regeneration shielding film 50 and is screwed to the cap 20, the portion contacting the cap 20 tends to be torn due to the nature of the biodegradable fiber have. In order to prevent this, a first reinforcing biodegradable fiber layer 55 is laminated around the hole. When the first reinforcing biodegradable fibrous layer 55 is laminated, it is possible to form the first reinforcing biodegradable fibrous layer 55 in such a manner that no pores are formed between the biodegradable fibers or more layers are stacked. Fig. 4 shows the arrangement relationship between the first reinforcing biodegradable fibrous layer 55 and the other fibrous layers. When the second reinforcing biodegradable fibrous layer 55 is laminated on the second reinforcing biodegradable fibrous layer 54, a small amount of biodegradable fibrous material is injected to reduce the thickness of the first reinforcing biodegradable fibrous layer 55, (55) can be laminated. And the second biodegradable fibrous layer 53 or the first biodegradable fibrous layer 52 below the second biodegradable fibrous layer 54 in the portion where the second biodegradable fibrous layer 54 is absent.

Figure 5 is a sectional view taken along line BB of Figure 2 in which a second reinforced biodegradable fibrous layer 56 may be laminated on the second biodegradable fibrous layer 54, The first biodegradable fibrous layer 53 or the first biodegradable fibrous layer 52 can be laminated in the portion where the first biodegradable fibrous layer 53 is absent. The second reinforcing biodegradable fibrous layer 56 may be formed in such a manner that it does not give pores between the biodegradable fibers like the first reinforcing biodegradable fibrous layer 55 or stacks more layers. The first reinforcing biodegradable fibrous layer 55 is laminated on the first biodegradable fibrous layer 52 to the second biodegradable fibrous layer 54 and is provided so as to extend along the longitudinal direction of the shielding film. When the alveolar bone regeneration shielding film 50 is to be implanted, a force that pulls the artificial root 10 through the hole of the shielding film 50 and then pulls the artificial root 10 using forceps may act in the longitudinal direction. At this time, The shielding film of the present invention made of a biodegradable fiber material may be torn. Thus, by stacking the second reinforcing biodegradable fibrous layer 56, such problems can be prevented. It is to be understood that the second reinforced biodegradable fibrous layer 56 may be laminated in three along the longitudinal direction at predetermined intervals as shown, the number of which may be selected as needed and is not necessarily limited to three .

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the scope of the present invention is defined by the claims that follow, and should not be construed as limited to the above-described embodiments and / or drawings. It is to be expressly understood that improvements, changes and modifications that are obvious to those skilled in the art are also within the scope of the present invention as set forth in the claims.
