Description

Reinforcement comprising stainless steel wire and glass fiber and manufacturing method

The present invention relates to a reinforcing material using stainless steel wire and glass fiber, and a method of manufacturing the same.

If a tooth is missing, it may be difficult to recover it with a prosthesis, such as a bridge. In this case, a treatment called a resin denture (false denture) is performed. There are two types of resin dentures (general dentures) and partial dentures. Ordinary resin dentures are placed on the gums with no teeth left, and partial dentures use metal skeletons, artificial teeth, and resin dentures to mount to areas with partially missing teeth. Conventional dentures were generally manufactured using only medical resins (Resin) or by inserting metal into the resin.

On the other hand, dentures using only medical resins may cause problems in the chewing activity of the wearer due to the weak strength of the dentures, and in particular, micro cracks may occur during various stresses such as tensile stress, vertical stress, and the like. . PMMA resin (poly methylmethacrylate resin), a resin mainly used for denture base, is used as a thermal polymerization resin material. However, when only the PMMA resin is used, due to the weakness of the strength, there is a problem that the fracture phenomenon occurs when ingesting hard food.

In order to compensate for the problem of dentures using only resin, dentures were manufactured by inserting a metal into the resin.However, in the case of metals, dentures using a resin only have excellent strength under various stresses, but the denture manufacturing process Due to the process of casting using a separate mold during the process, it took considerable time for manufacturing, and due to the characteristics of the metal, the weight and thickness were considerable, resulting in the discomfort in the mouth of the denture wearer.

In addition, the fabrication of metal reinforcement materials is complicated due to complicated processes (wax engraving, injection line attachment, investment, summoning, metal casting, etc.), elasticity in the metal itself, and elasticity only in the resin. Fracture of the resin can occur rather easily, and the weight of the metal reinforcement itself is high, which is likely to cause denture removal.

Therefore, a method of using glass fiber reinforcement instead of metal reinforcement has been developed, but glass fiber reinforcement has an advantage that can be manufactured in a simpler process than fabrication of metal reinforcement, but does not exhibit the reinforcing effect as metal reinforcement and is vulnerable to external impact.

Therefore, it is necessary to develop a reinforcing material that can be used in a new dental resin denture that can solve the above problems.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are intended to illustrate the present invention more specifically, but the scope of the present invention is not limited to these examples.

<Example 1>

Fabrication of reinforcement material using stainless steel wire and fiberglass

A reinforcement material was prepared for dental resin dentures incorporating stainless steel and photopolymerized glass fiber materials. The glass fiber strands for the reinforcement were made of E-Glass Fiber with a filament diameter of 17 μm. For binding, silane was treated with XIAMETER OFS-6030 and then combined with photopolymerized resin. After the bonding, the glass fiber and stainless steel wire were combined to form a circular bar type. The combined reinforcement was photocured for 5 minutes using a photopolymerizer to prepare a reinforcement using stainless steel and photopolymerized glass fibers according to the present invention.

Experimental Example 1

Flexural strength of the reinforcing material of the present invention prepared in Example 1 was analyzed. Specifically, after inserting the respective reinforcing materials prepared in Example 1 to the thermal polymerization resin, the three-point bending strength value was measured.

As a result, as shown in Table 1 and Figure 5, the three-point flexural strength value of the general resin was found to be 63.52 MP (5a), thermal polymerization resin applied to the general resin and a photopolymerized glass fiber of 5 mm width The value of was found to be 88.05 MPa (5b), and the value of thermally polymerized resin with photopolymerized glass fiber with a width of 10 mm was 67.05 MPa (5c).

In addition, the bending strength was measured by inserting a reinforcing material into the thermal polymer resin (PMMA), in the case of Figure 6a as a result of measuring the three-point bending strength value for the reinforcing material wrapped in the photopolymerized glass fiber in a stainless steel wire of 1.0 mm thickness, 148.74 MPa However, the reinforcement made using only stainless steel wire was found to have a value of 79.57 MPa (6b).

Flexural Strength Experiment Group Flexural Strength Example The details 3-point flexural strength 5A Thermal polymerization resin 63.52 MPa 5B Thermally polymerized resin + 5mm width photopolymerized glass fiber 88.05 MPa 5C Thermal polymerization resin + 10mm width photopolymerization glass fiber 67.05 MPa 6A Thermopolymer + Stainless Steel Wire + Photopolymer Glass Fiber 148.74 MPa 6B Thermopolymer + Stainless Steel Wire 79.57 MPa

Through these results, the present inventors were able to confirm that the reinforcement using the stainless steel wire and the light-curing glass fiber has a superior flexural strength value compared to the reinforcing material manufactured using only the photopolymerized glass fiber or the stainless-steel wire, and cracks are generated. Not only does not have a problem, but also due to the elastic properties of the stainless steel wire can minimize the problem of fracture, the reinforcement using the stainless steel wire and the photopolymerized glass fiber produced by the method of the present invention can be useful for dental resin dentures Could know.
