Description

Ultraviolet irradiation apparatus for surface treatment of dental implant

The present invention relates to an ultraviolet irradiation device for surface treatment of dental implants, and more particularly to an ultraviolet irradiation device for surface treatment of dental implants for hydrophilic modification of the surface of the implant to improve bone fusion with the periodontal tissue. .

In general, an implant means a substitute that can replace human tissue when the original human tissue is lost, but in the dentist, an implant of artificial teeth is implanted. In other words, it is a technology for restoring the function of the tooth by fixing the artificial tooth after planting a fixture made of a material that has no rejection reaction to the human body to replace the lost tooth root.

In the case of ordinary prosthetics or dentures, the surrounding teeth and bones are damaged over time, but dental implants can be used stably because they can prevent damage to surrounding dental tissues and there are no secondary caries. In addition, the dental implant has substantially the same structure as the natural teeth, there is no pain and foreign body feel of the gums, there is an advantage that can be used semi-permanently if you manage well.

Here, the dental implant placement is the artificial prosthesis (crowm), which is the final prosthesis after waiting for the first process of placing the fixture (fixture) in the alveolar bone and the period (3-6 months) that the fixture is osteointegration to the alveolar bone. A secondary process of fixation is included.

In detail, the first process includes the step of removing the gum tissue of the portion where the tooth is missing, the multi-stage drilling step of forming a perforation in which the fixture is to be placed in the alveolar bone, the step of fixing the fixture, and the step of coupling the temporary tooth to the implanted fixture. Include.

Then, after the first process, after the period for bone fusion, the temporary tooth coupled to the fixture is separated, the tooth implant is placed through the secondary process of removing the gum tissue regenerated around the temporary tooth and fixing the final prosthesis. Is complete.

On the other hand, the material used in the dental implant, in particular the fixture should not only be made of a very stable bio-compatible material for human tissue, but also have no chemical or physiological reactivity or human rejection. In addition, it is very difficult to select a suitable material because the mechanical strength must be high so that deformation or fracture is prevented even when repeated loads and instantaneous pressures are applied during the chewing.

Therefore, while various metals and alloys have been developed as a suitable material for the fixture, titanium metals and titanium alloys are currently used. Such titanium or titanium alloys are easy to process and yet have high biocompatibility, bioinertness and high mechanical strength for human biological tissues.

At this time, the titanium and its alloys themselves have an oxide film formed on the surface, but stability is secured compared to other metals, but it takes a long time for bone fusion when implanted into the human body, and in recent years, further improvement of human stability is required. Therefore, some technologies have been developed and applied to improve the bone fusion by appropriately treating the surface of the fixture made of the above materials to compensate for these disadvantages.

In particular, the rate and quality of bone fusion are closely related to the surface properties and chemical composition of fixtures such as surface composition, surface roughness and hydrophilicity. In particular, fixtures having a high hydrophilic surface are known to be advantageous for interaction with biological solutions, cells and tissues. Accordingly, some of the fixtures in which a titanium dioxide (TiO ₂ ) oxide film is coated on a titanium surface in order to improve biocompatibility while improving bone fusion are disclosed. In order to coat the titanium oxide film on the fixture surface, techniques such as plasma spraying, sputtering, and ion implantation have been disclosed.

However, there is a problem that the surface of the fixture is stabilized as carbon atoms are bonded as time passes after the oxide film treatment is converted into a hydrophobic surface of a low energy state. For this reason, the bone fusion ability is lowered when the fixture is converted to the hydrophobic surface as it is in the alveolar bone, and there is a serious problem of causing inflammation in the state in which the fixture is placed when the surface of the fixture is contaminated with organic matter.

Thus, some products have been released that include storage containers in which the hydrophilicity of surface modified fixtures can be maintained for a long time. However, a fixture including such a storage container is expensive and has a problem of increasing the financial burden on the consumer. In addition, there is a problem that the choice of the consumer is very narrow even though it is expensive because the product of a specific company must be used.

In order to solve this problem, a surface treatment ultraviolet irradiator which can remove organic contaminants attached to the surface while modifying the surface of the fixture by irradiating ultraviolet rays after mounting the fixture therein has been disclosed.

However, the conventional surface treatment ultraviolet irradiator has a problem that the implant placement does not proceed quickly because the exposure to the ultraviolet light for more than 2 to 3 hours substantially for the surface modification of the fixture. In addition, since the fixture is heated while being exposed to ultraviolet light for a long time, it takes more time to cool it, and there is a problem in that malfunctions of electrical appliances are generated due to high heat generated inside the apparatus. Moreover, when implanting a fixture that is not properly cooled, the implantation site tissue may be damaged, which further has a problem of acting as a negative factor for stable bone fusion.

In addition, the conventional UV irradiation for surface treatment has a problem that the secondary contamination is increased while the fixture is exposed to the external environment as the fixture is mounted inside the machine after separating the fixture from the container packed with the fixture. there was.

On the other hand, some of the packaging container is provided with an ultraviolet irradiation lamp in the container portion to be individually packaged fixtures, there is a problem that the overall cost of implant placement is increased because the cost of manufacturing each labeled container is expensive. In addition, when the ultraviolet irradiation lamps individually provided in the container portion is broken or damaged by external factors, there is a problem that the surface modification of the fixture is not substantially made, and thus, the bone fusion improvement effect is not provided.

In addition, the side surface portion may be separately provided on each side or integrally formed to correspond to the circumference of the bottom surface portion 771a may be assembled to the outer edge of the bottom surface portion 771a.

In addition, the bottom surface portion 771a may be provided as a single plate, divided along the transverse direction, one side is formed integrally with the front portion 772a, and the other side is formed integrally with the rear portion 772b. Such modifications may fall within the scope of the present invention.

In addition, the housing unit 770 may be provided with a display unit 777 for inputting and confirming a driving state of the ultraviolet irradiation device 700. That is, the driving signals of the ultraviolet lamp unit 720 and the rotation driving unit 740 may be easily input through input means such as a button or a touch unit provided in the display unit 777. In addition, information such as the UV irradiation amount of the ultraviolet lamp unit 720, the elapsed discharge time, the internal temperature of the reforming space (G), and the rotational speed of the rotary driving unit 740 may be displayed on the display unit 777. have. Therefore, the operator can visually and easily confirm this, so that the ease of use can be significantly improved.

It may be composed of any one selected from alloy steel such as steel.

At this time, the excimer lamp is formed by excimer molecules (molecules in the excited state) as the discharge gas filled in the container in a vacuum state is discharged by the electric force formed in the discharge electrode. And, when the excimer molecule transitions to the ground state, it emits ultraviolet light of a predetermined wavelength.

Therefore, since the surface of the modified object is hydrophilically modified through ultraviolet rays irradiated from the excimer lamp, the ultraviolet irradiation device 700 of the present invention may significantly improve the osteofusion ability. In addition, since the sterilization and cleaning operations are simultaneously performed by decomposing or removing the organic substances remaining on the surface of the modified object, hygiene may be significantly improved. In this case, the modified object is preferably understood as a dental implant that requires surface modification so that the bone fusion ability with the alveolar bone is improved, and implants such as fixtures (f) or abutments may be included therein. .

Here, the excimer lamp may be irradiated with ultraviolet rays, especially vacuum ultraviolet rays in the UV-C range having a wavelength of 100 ~ 200nm inside the vessel in a vacuum state. The vacuum ultraviolet rays are emitted in a large amount in a vacuum state, so that the amount of light is abundant, and because of the high energy of the short wavelength, the surface of the modified object can be quickly modified in a short time. Accordingly, the present invention can be provided with a good surface modification result while the rapid surface modification is made in about 5 to 10 minutes compared to the conventional surface modification using ultraviolet light for 2-3 hours or more.

In addition, far ultraviolet rays in the UV-C range having a wavelength of 200 to 280 nm pass through the vessel and are irradiated to the modified object side. Accordingly, the oxygen molecules around the reformed object are converted to the reactive generator ozone while the outer electrons are excited by the energy impact exceeding the binding energy. Through this, as the carbon atoms deposited on the surface of the modified object are separated from the ozone by binding, the surface of the modified object is converted from hydrophobicity in the low energy state to hydrophilicity in the high energy state, so that the osteolysis ability may be remarkably improved.

In addition, the container is provided with a quartz material having a light absorption coefficient lower than that of glass or projection synthetic resin that is generally used, the ultraviolet transmittance can be significantly increased, the sterilizing power of the ultraviolet light can be preserved. Through this, while the high energy far ultraviolet rays irradiated from the ultraviolet lamp unit 720 is substantially irradiated to the surface of the modified object, the surface modification ability and sterilization / cleaning ability can be significantly improved.

In this case, the plurality of rollers 732 are preferably arranged adjacent to each other so that the rotational seating area J in which the modified object is seated is formed along the longitudinal direction of the upper surface of the opposite inner surface. In addition, each interval in which the plurality of rollers 732 are disposed adjacent to each other may be formed to be shorter than a short width interval of the modified object, that is, a cross-sectional width in the longitudinal and vertical directions.

Hereinafter, the plurality of rollers 732 will be described and illustrated as an example of a pair.

In detail, the ultraviolet lamp portion 720 and the pair of rollers 732 may be provided in parallel with each other, and may be disposed in a transverse direction, that is, in a horizontal direction so as to substantially correspond to the bottom surface portion 771a.

Therefore, the modified object can be easily mounted or detached from the ultraviolet irradiation device 700 by a simple method of placing the modified object along the longitudinal direction of the rotational seating area J, and thus the usability can be remarkably improved. In addition, since the state in which the modified object is seated in the rotation seating region J is stably supported in the direction of gravity by its own weight without additional restraining or coupling means, driving safety may be significantly improved.

Further, the pair of rollers 732 are each provided in a cylindrical shape, the upper portion of the opposite inner surface side is concave, but is provided with a profile that is convex toward the opposite outer surface side. Through this, even if the modified object seated in the rotation seating area (J) is rotated relative to the center thereof can be prevented from changing the rotation position or to the outside of each of the opposite outer surface. In addition, since the center of rotation of the modified object is rotated while being maintained at a predetermined interval from the outer surface of the ultraviolet lamp unit 720, the surface modification can be made uniform. Here, it is preferable that the modified object is rotated in the same sense as being substantially rotated.

In this case, the pair of rollers 732 extend in correspondence with the longitudinal direction of the ultraviolet lamp portion 720, the ultraviolet lamp portion 720 and the pair of rollers 732 exceed the long width of the modified object Is preferably formed. For example, the pair of rollers 732 may be extended to a length that can be arranged at the same time in the longitudinal direction of the four to five places of the modified object, the ultraviolet lamp portion 720 is such a pair of rollers 732 It can extend to a length that can cover the whole. Through this, the plurality of modified objects can be surface treated at one time through one UV lamp unit 720, so that the usability and economic efficiency can be significantly improved.

In addition, the ultraviolet lamp unit 720 is provided in a cylindrical shape, the pair of rollers 732 may be provided symmetrically with respect to the longitudinal center of the ultraviolet lamp unit 720. Therefore, since the rotational seating area J formed on the upper inner side of the pair of rollers 732 substantially corresponds to the longitudinal center of the ultraviolet lamp portion 720, the upper outer surface of the modified object and the ultraviolet lamp The lower outer surface of the portion 720 may be disposed as close as possible.

On the other hand, the rotation driving unit 740 is provided to provide a rotational force so that the pair of rollers 732 is rotated, it is preferable to include a rotary pulley 741, the drive motor 742 and the belt 743.

In detail, the rotatable pulley 741 is provided to correspond to the pair of rollers 732, respectively, and is preferably fastened coaxially with the rotation axis of each roller 732 to at least one of both ends of each roller 732. . In addition, the belt 743 is preferably provided to simultaneously wrap the pair of rotary pulleys 741 and the rotating shaft connected to one side of the driving motor 742 corresponding to the pair of rollers 732.

The roller 732 is rotated simultaneously. Accordingly, as the modified object seated in the longitudinal direction of the rotary seating area J is rotated while rubbing against the surfaces of the pair of rollers 732, the ultraviolet ray irradiated from the ultraviolet lamp unit 720 is modified. It can be irradiated uniformly on the whole surface of the.

Furthermore, the roller 732 may be stably rotated in response to the rotational speed and the number of rotations of the pair of rollers 732 as the outer surface is formed to have a predetermined coefficient of friction. Therefore, since the surface of the modified object is uniformly modified as a whole, the bone adhesion after implant placement can be significantly improved. Of course, in some cases, the rotary pulley may be provided in a sprocket shape and the belt may be provided in a chain shape. Such modifications fall within the scope of the present invention.

On the other hand, the ultraviolet lamp unit 720 is connected to the lifting frame 774, it is preferable that the lifting frame 774 is provided to selectively lift. Accordingly, the ultraviolet lamp portion 720 may be selectively approached or spaced apart from the outer surface of the outer side of the rotary jig portion 730 is arranged below. At this time, the outer outer surface of the rotary jig 730 means the outer surface of the pair of rollers 732, more preferably the upper outer surface on which the modified object is seated.

In detail, the UV lamp unit 720 in the lowered state of the lifting frame 774 may be disposed to be close to the upper outer surface of the pair of rollers 732. Further, in the lowered state of the lifting frame 774, the interval between the lower outer surface of the ultraviolet lamp portion 720 and the upper outer surface of the pair of rollers 732 is set to less than the short width interval of the modified object, a predetermined rotation Preferably, the clearance gap w is provided.

In this case, the modifying object is accommodated therein, it is preferable to include an amp 750 provided with an ultraviolet projection window (751) so that the ultraviolet ray for the surface modification of the dental implant is transmitted. That is, the dental implant may be directly seated in the rotational seating area J. Preferably, the tooth implant is accommodated and seated in the ampoule 750 to minimize contamination due to direct exposure and contact with the external environment. Hygiene can be improved.

In detail, referring to FIG. 4, the ampoule portion 750 includes a hollow cylindrical projection body including the ultraviolet projection window 751, and stoppers 752a and 752b are formed on both sides of the projection body. Can be combined.

In this case, as the ultraviolet projection window 751 is formed on the entire body of the projection body portion, the ultraviolet ray may be substantially transmitted along the circumferential direction of the ampoule portion 750. Accordingly, the ampoule portion 750 may be seated in the rotational seating area J and the ultraviolet rays may be irradiated onto the entire surface of the dental implant accommodated therein, thereby significantly improving the surface modification ability.

Here, through passages 756a and 756b may be formed along the longitudinal direction of the stoppers 752a and 752b so that oxygen molecules are supplied into the projection body. In addition, in order to prevent contamination of the reformed object due to reuse of the ampoule unit 750, the ampoule unit 750 may be attached to a near field communication (NFC) tag.

Hereinafter, the modified object is described and illustrated as an example provided with the ampoule 750. In this case, the tooth implant accommodated inside the ampoule 750 is illustrated as an example having a fixture f, but is not limited thereto, and is generally applied to an implant requiring a surface modification such as an abutment. Can be used.

In detail, referring to FIGS. 3 to 4, the ampoule portion 750 in which the fixture f is accommodated is disposed on the upper side of the opposite inner surface of the pair of rollers 732, that is, in the longitudinal direction of the rotation seating area J. FIG. It is seated accordingly. Here, when the lifting frame 774 is lowered, the lower outer surface of the ultraviolet lamp unit 720 may be disposed adjacent to the upper outer peripheral surface of the ampoule portion 750.

When the pair of rollers 732 are rotated in the same one direction by the rotational force transmitted when the rotary driver 740 is driven, the ampoule 750 is rubbed with the surfaces of the pair of rollers 732 while the other side is rubbed. Is rotated in the direction.

In this case, the modified object is supported in the direction of gravity by the weight of the ampoule portion 750 and the fixture f accommodated therein and rotates in the rotational seating area J, thereby modifying the surface in a minimum space. This can be done. That is, the reformed space G requires only a minimum space in which the ultraviolet lamp portion 720, the pair of rollers 732, and the rotation driving part 740 can be accommodated. It can be compact and compact. In addition, the components for the surface modification of the reforming object is provided with a simple structure that is sequentially stacked in the reforming space (G) and the shape of each component is not complicated, the assembly / manufacturing labor and manufacturing cost can be significantly reduced. .

Here, a fixing unit 733 may be provided to fix the pair of rollers 732 so that the centers of rotation of the pair of rollers 732 rotated by the driving of the rotation driving unit 740 are supported. Here, the fixing portion 733 is provided in a pair so as to correspond to both ends of the pair of rollers 732, the lower end is fixed to the bottom surface portion 771a and the upper end of each end of the pair of rollers 732 Can be rotatably coupled. Therefore, even when the elevating operation of the elevating frame 774 or the driving of the rotary drive unit 740, the position of the upper surface of the pair of rollers 732 is fixed constantly, driving reliability can be significantly improved.

On the other hand, the rotation margin (w) is preferably set in the range 0.5 ~ 5mm.

That is, as the minimum space of the rotation margin (w) is set to 0.5 mm or more, the outer circumferential surface of the ampoule portion 750 and the lower outer surface of the ultraviolet lamp portion 720 may be disposed close to each other at the minimum rotational interval. have. Therefore, even if the ampoule 750 is rotated, the contact and interference with the ultraviolet lamp 72 is prevented, and thus the damage or the ampoule 750 is pressed by the ultraviolet lamp 750, thereby rotating. By preventing interference, driving stability can be significantly improved.

In addition, as the maximum interval of the rotation margin (w) is set to 5mm or less, the interval between the lower outer surface of the ultraviolet lamp portion 720 and the surface of the ampoule portion 750 is set to the minimum interval that can be rotated Can be. Therefore, since the energy attenuation rate due to exposure of short-wavelength ultraviolet rays, especially vacuum ultraviolet rays, to the air is minimized, the entire circumferential surface of the dental implant through high-energy ultraviolet rays can be uniformly modified and sterilized in a short time.

Furthermore, a first interval in which the outer outer surface of the rotary jig 730 and the lower outer surface of the ultraviolet lamp unit 720 are spaced apart from each other in the lowering state of the elevating frame 774 is an upper outer surface of the ampoule portion 750. The lower outer surface of the ultraviolet lamp unit 720 may be set to an interval that can be spaced apart corresponding to the rotation margin (w). In this case, the first interval may be formed in a width exceeding the radius of the ampoule portion 750 but smaller than the outer diameter.

In detail, the rotation seating area J is formed on an opposite inner surface formed with a concave profile while the pair of rollers 732 are adjacent to each other, and the ampoule 750 maintains a constant rotation center during rotation. It is provided in a circular shape. Therefore, the ampoule portion 750 may be seated in a shape in which the pair of rollers 732 are partially inserted into the concave profile disposed adjacently. Therefore, the distance between the upper surface of the ampoule portion 750 and the upper outer surface of the pair of rollers 732 seated in the rotation seating area J may be formed to have a width smaller than the outer diameter of the ampoule portion 750. .

In addition, the gap between the opposing inner surfaces of the pair of rollers 732 is the outer diameter of the ampoule portion 750 so that the ampoule portion 750 may be seated in contact with the upper surface of the opposing inner surfaces of the pair of rollers 732 at the same time. It is formed smaller. Therefore, the distance between the upper surface of the ampoule portion 750 and the upper outer surface of the plurality of rollers 732 seated in the rotation seating area J may be formed to have a width larger than the radius of the ampoule portion 750. .

Through this, the lower outer surface of the ultraviolet lamp unit 720 in the lowered state of the lifting frame 774 may be regularly spaced corresponding to the upper outer surface of the ampoule portion 750 and the rotation margin (w). . Therefore, since the ampoule portion 750 is stably seated on the pair of rollers 732 and rotated at a constant rotation speed, the surface of the dental implant may be uniformly modified as a whole.

In addition, the outer surface of the UV lamp unit 720 and the ampoule unit 750 may be prevented from being damaged due to friction or contact due to friction or contact with each other, thereby improving driving reliability. In addition, since the interval at which the short wavelength ultraviolet rays reach the surface of the modified object is minimized, the surface modification ability can be significantly improved.

In this case, as the ultraviolet lamp unit 720 is further provided with a coupling portion at the end of the lifting frame 774 so that the attachment and detachment from the lifting frame 774 may be improved maintainability.

In detail, the coupling part may surround the outer circumferential surfaces of both ends of the ultraviolet lamp part 720, and one side may be formed at an interval narrower than an outer diameter of the ultraviolet lamp part 720. That is, the both ends of the ultraviolet lamp portion 720 may be inserted through the opened side or slide may be inserted in the lateral direction of the coupling portion.

At this time, the coupling portion may be provided with a material having excellent elastic restoring force. Accordingly, the connection or separation of the UV lamp unit 720 is completed while the opening one side gap is easily deformed to correspond to the outer diameter of the UV lamp unit 720 when the UV lamp unit 720 is connected or disconnected. Can be restored from the state of the shot. In addition, as the coupling part is made of a non-conductive material, safety can be improved by preventing current transmitted to the ultraviolet lamp part 720 from being conducted to the door part 773 or the housing part 770 through the coupling part. have.

Here, the fixing part 733 or the lifting frame 744 may be further provided with a gap adjusting means so as to maintain the rotational clearance gap w corresponding to the short width of the reforming target part. For example, the fixing part 733 may be provided with a gap adjusting means for adjusting the interval between the rotating shaft of the plurality of rollers 732 and the bottom surface portion 771a. Accordingly, since the distance between the ultraviolet lamp portion 720 and the plurality of rollers 732 may be elastically adjusted to correspond to the outer diameter of the modified object, it may be used universally to correspond to the modified object of various sizes. .

In addition, the roller may have a plurality of ring-shaped protrusions formed in the longitudinal direction along the circumferential direction, and the engaging groove corresponding to the protrusion may be formed in the ampoule portion along the circumferential direction of the plug portion.

In this case, one end of the elevating frame 774 may be hinged to one edge of the opening 771c, and the above-mentioned elastic member connects one side of the elevating frame 774 and the housing 770 in the vertical direction. It may be provided to. Alternatively, one side of the elevating frame 774 in the lowered state of the elevating frame 774 is supported by being locked to the edge of the opening 771c, but may be manually separated outward.

When the door part 773 and the opening 771c face each other in the closed state of the door 773, the power supply state is maintained, but when the door part 773 is spaced apart from the open state, Sensor parts (s1, s2) for sending a signal to block the supply may be further provided.

In detail, in the closed state of the door unit 773, the sensor units s1 and s2 are in contact with each other, and thus the power supply state is maintained so that power is supplied to the ultraviolet lamp unit 720 and the rotation driving unit 740. The surface of the modified object may be modified to be hydrophilic. And, in the open state of the door unit 773, when the line is separated from each other and transmits a power cutoff signal, the control unit receives this to discharge the ultraviolet lamp unit 720 and the rotation of the driving unit 740 It can be controlled to stop the rotation. As a result, power consumption and ultraviolet rays emitted by the UV lamp 720 unnecessarily in the open state of the door part 773 may be prevented from damage to the skin or eyesight of an operator who is located adjacent to it. .

In addition, restraining means may be further provided to restrain the closed state of the door part 773. The restraining means may be provided with protrusions protruding from one side of the door portion 773 and the opening 771c facing each other and a groove into which the protrusions are fitted. Alternatively, the restraining means may be provided as a magnetic to restrain the closed state of the door part 773 and the opening 771c by magnetic force. Therefore, since the door part 773 is arbitrarily opened in the driving state of the ultraviolet lamp part, the safety may be improved when the product is used.
