Description

[0001] Dental implant fixture packing case [0002]

The present invention relates to a packaging case for safely packaging a dental implant fixture (dental implant fixture) which can maintain a hydrophilic titanium surface obtained through ozone (UV), ultraviolet ozone (UVO) and plasma cleaning until the dental treatment , And more specifically, a dental implant fixture is provided in a body or window to absorb and adsorb carbon dioxide and hydrocarbons in a mixed state to maintain a hydrophilic titanium surface for a long period of time Implant fixture packaged case.

The surfaces of RBM and SLA, which are widely used today, increase in oxidation layer over time when the surface is exposed to air after the treatment process, and the surface energy is chemically stabilized by the pollution source such as hydrocarbon material and becomes hydrophobic.

The hydrophobic surface has a low affinity for body fluids and blood, thereby decreasing wettability. When the implant is implanted in the human body, the bone fusion reaction is slowed down. As a result, it takes a long time for the implant to stabilize in the human body do.

To solve this problem, a hydrophilic material is coated or irradiated with ultraviolet rays to increase the energy of the surface to secure hydrophilicity. In order to maintain hydrophilicity by UV irradiation for a long time, This is becoming a distribution.

A representative example of the dental implant is disclosed in Korean Registered Patent Application (B1) No. 10-1213355 (Dec. 18, 2012). The dental implant has improved initial safety and a method of manufacturing the dental implant. The dental implant has a rough surface. And an osteoclast activity inhibitor coating layer formed on the surface of the dental implant to enhance an initial stability of the implant and an implant-bone interfacial bonding force. The osteoclast activity inhibitor is released from the coating layer to the peripheral alveolar bone during implantation, The released osteoclast activity inhibitor provides an initial stability of the implant by controlling the initial bone remodeling of the implant-bone interface by interfering with the bone resorption of the peripheral alveolar bone.

On the other hand, activated carbon, activated carbon fiber, zeolite and silica have the following characteristics and have a very large effect for adsorption of gas and moisture, as an adsorbent (6) that absorbs and adsorbs carbon dioxide and hydrocarbons And has the following characteristics.

- Activated carbon

Activated carbon is strongly adsorbed, and most of the constituent materials are carbonaceous substances. They are used as adsorbents to absorb gases and moisture, or as decoloring agents. Treating the wood or lignite with a chemical such as zinc chloride and drying it.

- Activated carbon fibers (carbon fibers)

Activated carbon fiber is characterized by high non-elasticity ratio among non-elasticity and non-elasticity, and when it is hardened with resin, it becomes light and does not deform well. Active (active) carbon fibers are used for air purification and the like.

- zeolite

Zeolite is a general term for minerals that are aluminum silicate hydrates of alkali and alkaline earth metals. The color is colorless transparent or white translucent. It is also called zeolite, and it has many kinds, but it has commonality with many points such as water content, crystal properties, and acidity.

Crystalline structure of each atom is loosened, so that even if the water filling the space is discharged as a high heat, the skeleton remains, so other fine particles can be adsorbed. This property is used as an adsorbent, and it is used as a molecular sieve (molecular sieve) for separating fine particles of different sizes.

- silica

Silica is also referred to as silicon dioxide or silicic anhydride. Quartz, quartz, agate, and opal are produced in nature, and quartz is representative. Since it is transparent from outside to outside, it is used for prism. It is usually colored with impurities. A silica gel in which silica is dehydrated into a granular form is called an excellent adsorbent, which can be used for adsorption and recovery of moisture and solvent, and can be regenerated.

The present invention is characterized in that the outer case 2 and the body 3 are made of carbon dioxide and the like as described above, taking into account the fact that the respective members constituting the packaging case 1 are constituted by injection molding, The adsorption material 6 absorbing and adsorbing hydrocarbons is mixed so that the surface of the implant fixture 10 is hydrophilized and the osteoclast activity inhibitor coating film is formed. The surface of the implant fixture 10 is oxidized by the carbon dioxide and the hydrocarbons.

The thermoplastic resin and the adsorbent material (6) are mixed with 70 to 90% of the thermoplastic resin in a weight ratio of 30 to 10% of the adsorbent material (6). When the adsorbent 6 is added in an amount of 10% or less, the adsorption function is insignificant and the effect is not significant. When the adsorbent 6 is added in excess of 30%, the formability is poor.

When two or more adsorbent materials (6) are used, they may be mixed in the same ratio.

In the figure, reference numeral 20 denotes a solid body of the adsorbent material inserted into the fixing pipe 3a of the body 3, and the adsorbent solid matter is contained in the packaging container 10 of the dental implant fixture 10 of Patent No. 1343817, And detailed description of the configuration is omitted.
