Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a UV irradiation system for recovering surface aging of a dental implant,

The present invention relates to an ultraviolet irradiation system for restoration of surface aging of a dental implant, and more particularly, to an ultraviolet irradiation system for restoring the surface reactivity of a reduced implant due to aging during ultraviolet irradiation, And an ultraviolet irradiation system for restoring the surface aging of a dental implant that enables stable use of artificial teeth for a long period of time.

Generally, a dental implant is made of titanium, and includes a fixture, which is placed in the jawbone and serves as a root, an abutment connected to the fixture to connect the prosthesis, and an abutment .

In the dental implant, the role of the fixture placed on the jawbone is very important in firmly fixing the tooth of the implant and normally exhibiting its function.

The connection between the fixture and the jawbone, that is, the bone, is called osseointegration. The better the osseointegration is, the more stable the implant tooth can be used for a long period of time. On the other hand, if the osseointegration is poor, the ability of the fixture to resist the occlusal pressure is reduced, and the problem of the implant tooth being reapplied in a short time is caused.

In addition, dental implants require time from the placement of the fixture in the jawbone to the fixation of the fixator, usually 2 to 4 months in the mandible and 6 to 7 months in the maxilla. Therefore, when the fixture has a good ability to induce osseointegration, the fixture can be inserted into the jawbone and then be attached to the jaw bone more rapidly, so that the period of the implant treatment can be greatly shortened.

The fixture is made of titanium, oxidized in air to form an oxide film, and the composition of the oxide film is TiO ₂ . The oxide film is stable and improves the biocompatibility of the fixture. When the solid body has a rough surface, the reaction of the osteoblast is better, and the surface is roughly treated to improve the degree of osseointegration.

Examples of the surface treatment method of the fixture include a method of acid etching the surface, a method of spraying particles on the surface of the implant, a method of mixing the two methods, anodic oxidation . Apart from this, a method has been proposed in which the hydroxyapatite, which is similar to the bone constituent of the human body, is coated on the surface of the implant to enhance the biocompatibility of the implant. In recent years, an attempt has been made to coat the surface of an implant with a bone formation promoting factor such as BMP-2 (bone morphogenic protein).

Dental implants have a shelf life of 5 years, usually in the state of being packaged after they are produced. A large number of products are stored for each size of dental clinic after the implant is manufactured and distributed. After that, when the patient goes to the hospital to receive the implant treatment, the implant, that is, the fixture corresponding to the size is placed on the patient. Therefore, it usually takes more than four weeks from production to the period of implantation.

However, in the above-mentioned fixture made of titanium, in the test in which a comparison was made between immediately after production and a predetermined period (4 weeks or more), the fixture immediately after being produced from the surface of the fixture for 4 weeks or more, bioactivity resulted in better results.

More specifically, a titanium disk with an acid-etched or sandblasted treatment is placed on a fresh surface immediately after production and an aged surface stored in a dark room for 4 weeks. When incubated for 2 hours, the adsorption of albumin on the aged surface for 4 weeks was only about 15% of the fresh surface immediately after the production.

In addition, human mesenchymal stem cells were cultured for 24 hours on a titanium disc immediately after production and a 4-week-preserved titanium disc. As a result, It is less than half that of a titanium disk.

Cell proliferation, alkaline phosphatase activity and calcium deposition were significantly lower than fresh surfaces on a 4-week-preserved titanium disk. On the aged surface irradiated with ultraviolet light, All of the items were higher than the fresh surface.

The alkaline phosphatase is an enzyme that secretes osteoblasts when bone is formed, and the higher the value, the better the number and activity of osteoblasts. That is, undifferentiated mesenchymal cells are well differentiated into osteoblast cells and bone is well formed

As described above, the fixture made of titanium has a problem in that the surface reactivity is aged and the degree of osseointegration becomes lower when the fixation body takes more than a certain period of time immediately after production.

As described above, in order to solve the surface aging problem of the fixture made of titanium in the implant and being placed in the jaw bone, the implant that has been manufactured over a certain period of time after being produced is opened in a sterile package, placed in a case, irradiated with ultraviolet rays, An implant surface treatment apparatus for restoring the degree of osseointegration on the surface of the fixture has been proposed.

However, there is a disadvantage in that if an implant that has been opened in sterilized packaging and subjected to a surface treatment is not applicable to a patient during actual surgery, it must be disposed of and it is troublesome to select ultrasound surface treatment process .
