Description

Ultraviolet activator for implant surface treatment

The present invention relates to an ultraviolet irradiation device, and more particularly, to an ultraviolet irradiation device for implant surface treatment.

In general, when the original human tissue is lost, the implant means a substitute that can replace the human tissue, but in dentistry refers to the implantation of artificially made teeth. In other words, it is a technology that restores the function of teeth by implanting a fixture made of a material that does not have a rejection reaction in the human body to replace the lost root in the alveolar bone from which the tooth has escaped, and then fixing the artificial tooth.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but implants can prevent damage to the surrounding tooth tissue and can be used stably because there is no secondary cause of caries. In addition, since the implant has the same structure as a natural tooth, there is no pain or foreign body feeling in the gums, and it can be used semi-permanently if well managed.

Here, the implant procedure is a primary procedure for placing a fixture in the alveolar bone, and a secondary procedure for fixing the final prosthesis (crown) after waiting for the time (3-6 months) for the fixture to osseointegrate into the alveolar bone. includes

In this case, the material used for the dental implant should not only be made of a biocompatible material that is very stable with respect to human tissue, but also should not have adverse effects on the human body, other chemical or biochemical reactivity or body rejection.

Therefore, various metals and alloys have been tried as suitable materials for the implant, but currently, titanium metal or titanium alloy is mainly used, but there is a need for more improved human body stability.

In particular, it is known that an implant having a high hydrophilic surface is advantageous for interaction with biological solutions, cells and tissues.

Accordingly, recently, a UV irradiation device for surface treatment that can improve surface modification while removing organic contaminants attached to the surface by irradiating UV light after mounting the implant fixture inside has been partially disclosed.

However, the UV irradiation device for surface treatment presented in the prior art requires the configuration of a cooling device, so that the user's convenience is required with a more compact configuration of the device.

The implant surface treatment unit 200 using a UV lamp is disposed on the body body 300, and the implant surface treatment unit 200 has ultraviolet rays on the surface of the implant fixture f (hereinafter referred to as a fixture) mounted on the cradle. It enables hydrophilic surface modification as it is irradiated with (UV).

2 to 4, the implant surface treatment unit 200 is coupled to the UV lamp unit 210 for irradiating UV light to the inner surface, the UV lamp unit 210, the fixture (f) is mounted. The holder 220 and the UV lamp unit 210 are supported and combined with the holder 220 to raise the holder 220 so that the fixture f is mounted on the UV lamp unit 210 or By lowering the holder 220 , the fixture f includes a lamp support 230 for releasing the mounting with the UV lamp 210 .

Here, the holder 220 includes a screw tap driver 221 to which the fixture f is coupled in the form of a screw coupling or a groove/protrusion coupling, a driver holder covering the screw tab driver, and the lower part is a circle A driver holder bracket 222 having a support plate coupled to and supported by the driver holder in a groove/protrusion manner in a plate shape and a side plate that rises or falls for coupling with the UV lamp unit 210 in a vertical direction is provided. In this case, the screw tap driver 221 , the driver holder, and the holder bracket) constituting the cradle 220 is preferably made of a metal material such as aluminum (Al).

In addition, the lamp support part 230 may form a guide part (not shown) as a vertical movement path through which the driver holder bracket 222 of the holder 220 rises or descends. In this case, as a vertical movement path, the guide part is implemented in the form of a rail, and a motor driving the ball screw or LM guide method may be further provided.

In addition, the UV lamp unit 210 irradiates ultraviolet rays to the inside through the UV lamp, and includes a lamp case body 214 as an outer housing, and a lamp case top 215 formed on the upper portion of the body. The UV lamp unit 210 housed in this way is supported by being coupled to the lamp support unit 230, and the case body bracket 231 and the case body bracket 231 are coupled to the guide unit which is the vertical support of the lamp support unit 230. and a case body guide pin 232 horizontally connected to the lamp case body 214 of the UV lamp unit 210 in a pin structure. In this way, the UV lamp unit 210 is connected to and coupled to the lamp support unit 230 through the case body bracket 231 and the four case body guide pins 232 .

In addition, the UV lamp unit 210 includes a UV lamp 221 having a donut-shaped hollow part, and an ampoule part 222 coupled to the hollow part of the UV lamp 211, and the ampoule part 222 is provided. has an open lower portion and is coupled to the screw tap driver 221 of the holder 220 through the lower opening so that the fixture f is mounted on the ampoule part 222 .

At this time, the fixture (f) is coupled to the screw tap driver 221 of the holder 220, when the holder 220 rises through the motor in the open state as shown in FIG. When combined with the UV lamp unit 210, the screw tap driver 221 is inserted through the lower opening of the ampoule unit 222, and the fixture (f) is positioned in the inner space of the ampoule unit 222. 220) is in the close state (see FIG. 2b).

As shown in Figure 2b, when the holder 220 is in the close state, the UV lamp 221 is provided along the outer peripheral surface of the ampoule part 222 in which the fixture (f) is inserted, so the UV lamp 221 is a donut. Ultraviolet rays may be irradiated inward toward the inner peripheral surface of the entire circumferential direction toward the fixture located therein in the form of a shape.

At this time, the ampoule part 222 is in the form of a UV projection window through which the UV light irradiated from the UV lamp 221 is transmitted to modify the surface of the dental implant accommodated therein, that is, the fixture f. Through this, it is possible to visually confirm the state of UV irradiation. In addition, the ampoule part 222 has an open lower portion, and the lower opening portion is closed by being coupled to the screw tap driver 221 of the holder 220 .

As such, the UV lamp unit 210 is a space for accommodating the implant fixture seated on the screw tap driver 221 of the cradle 220 therein, and the ampoule unit 222 and the ampoule unit 222 are externally formed in a donut shape. A UV lamp 221 is provided to cover while wrapping in.

At this time, the UV lamp 210 may be implemented as a donut-shaped container made of a quartz material, provided in a vacuum pressure state with a discharge gas filled therein, and an excimer lamp provided with a discharge electrode on the side. ) is preferably provided. More specifically, the discharge gas may be a halogen gas such as fluorine or chlorine, or a gas such as xenon or krypton. Also, the discharge electrode may be provided in the form of a rod, a spring, a pipe, or a conductive tape. In addition, the discharge electrode is a conductive material having excellent electrical conductivity such as aluminum, aluminum alloy, duralumin, copper and copper alloy, silver paste, conductive coating solution such as ITO (Indium Tin Oxide), ATO (Aluminum Tin Oxide), and restoring force It may be formed of any one selected from alloy steels such as excellent stainless steel.

In such an excimer lamp, excimer molecules (molecules in an excited state) are formed as the discharge gas filled in a vacuum pressure state in a container is discharged by an electric force generated by the discharge electrode. Then, the excimer molecule (Xe2*) transitions to Xe to the ground state and emits ultraviolet rays of a preset wavelength, for example, a wavelength of 172 nm. Such ultraviolet rays are emitted in a large amount under vacuum pressure, so that the amount of light is abundant, and since it has a high energy of a short wavelength, the surface of the fixture (f) can be rapidly modified in a short time. Accordingly, the oxygen molecules present in the ampoule part 222 in which the fixture f is inserted are converted into an excited state through an energy impact exceeding the binding energy, and converted into ozone, which is a reactive generator. Through this, as the carbon atoms deposited on the surface of the fixture (f) are combined with the ozone and separated, the surface of the fixture (f) can be converted from hydrophobicity in a low energy state to hydrophilicity in a high energy state. That is, the 172 nm vacuum UV light _{converts the atmosphere around the excimer lamp into an O 3} atmosphere, and the surface of the fixture f may be modified to be hydrophilic through the UV light irradiated from the excimer lamp. At this time, by decomposing or removing the remaining organic matter, the sterilization and cleaning action may be performed at the same time.

In addition, for the surface modification of the implant fixture, it is exposed in a short time to near-ultraviolet rays having a relatively low energy of 172 nm wavelength, so there is a low risk of damage due to heating, so there is no need for a separate complicated cooling means. can be compactly provided.

Moreover, as the container of the UV lamp 222 is made of a quartz material having a lower extinction coefficient than a generally used glass or projection synthetic resin container, the UV transmittance can be significantly increased, and the sterilization power of the UV can be preserved. have.

In addition, the ampoule unit 222 is an ultraviolet projection window, which is provided in a cylindrical shape with an open lower portion, and is preferably made of a quartz material of projection.

Accordingly, as the container of the UV lamp 221 and the ampoule part 222 provided therein are made of a quartz material having high ultraviolet transmittance, vacuum ultraviolet rays are substantially transmitted from the UV lamp 221 to the fixture (f) can be irradiated on the surface of

In addition, the ampoule part 222 has a structure that is coupled and sealed with the screw tap driver 221 of the cradle 220 raised through the lower opening with the lower part open, and an air hose for discharging ozone generated as needed at the upper part. An upper hole coupled to the 213 may be formed.

In addition, it is preferable that the connection part between the screw tap driver 221 and the ampoule part 222 be completely sealed through an O-ring or the like. In addition, the inside of the ampoule part 222 may also be provided in a closed state similar to the vacuum pressure state of the ultraviolet lamp 221 . It is possible to reach the surface of the fixture (f) by substantially penetrating the ampoule part (50).

Referring to FIG. 4 , it can be seen that the inner diameter of the UV lamp 221 is designed to be Ø10.0mm in order to increase the surface modification and sterilization cleaning power and maximize the hydrophilicization performance through the ultraviolet irradiation device 100 according to the present invention. Also, even if the experiment of inserting and reopening the implant fixture in the ampoule part 222 in the UV lamp is performed several times, the inner diameter is Ø10.0mm without fear of interference and damage (error range is from a minimum of 0.3mm to a maximum of 0.6) mm range) is preferred.

Through this, ozone generated when the lamp is turned on decomposes and evaporates the carbon layer attached to the implant surface, so that the bone formation can be attached to the implant surface well.

In addition, when ultraviolet light increases the hydrophilicity of the implant surface to wet the implant surface with blood, the well-formed blood clot on the implant surface causes the bone-forming cells to adhere well to the implant surface.

In addition, UV light changes the implant surface charge from (-) charge to (+) charge, and it electrostatically attracts and adheres to the implant surface by attracting (-) charged human cells and proteins that help the adhesion and function of those cells. Therefore, the bonding strength can be improved.

First, a user authentication process is performed (S510). That is, by recognizing the RFID card, the number of times the UV irradiator is used is preset and provided to the user, so that the user can be identified and the number of times of use can be recognized.

Then, the holder 220 is opened through the motor or ball screw control (S520), the implant fixture (f) is opened from the ampoule case, inserted into the screw tap driver 221 of the holder 220, and mounted (S530) ), press the start button on the touch screen (S540).

Then, the cradle 220 is raised by driving the DC motor and closed in close contact with the UV lamp 210, and the DC pump is operated for 5 seconds to remove oxygen from the inside of the ampoule of the UV lamp (S550). At this time, in order to minimize ozone generation, the DC pump is driven to remove the air inside the UV lamp through the activated carbon filter to maintain the maximum vacuum.

Then, the ballast is turned on for 30 seconds, and in order to increase the hydrophilicity of the implant surface, a UV lamp of 172 nm wavelength is turned on for 30 seconds to perform UV irradiation to remove hydrocarbons on the implant surface to increase the hydrophilicity (S560).
