Description

Technical Field

[0001] The present application belongs to the technical field of material processing of glass ceramic restorations during oral restoration, and specifically, relates to a hydrofluoric acid treatment device for glass ceramic restorations. Background Art

[0002] Inlays, onlays, veneers, endodontic crowns and other glass-ceramic restorations that are fixed by resin bonding are increasingly being used in the field of oral restoration. Surface treatment of glass-ceramic before bonding is crucial to forming a stable bond. Treatment with hydrofluoric acid and silane coupling agents is the gold standard for surface treatment of glass-ceramic. The main component of glass-ceramic is a silica glass matrix. Hydrofluoric acid can selectively dissolve the glass matrix, increase the roughness of the bonding surface, the bonding area and the surface activity. Hydrofluoric acid is a weak acid with extremely strong corrosiveness, which can strongly corrode metals, glass and silicon-containing objects. It does not dissolve the glass matrix through acid etching, but through the active fluoride ions and the glass matrix to generate fluorosilicic acid that can be washed away by water.

[0003] However, hydrofluoric acid is highly corrosive to the skin, eyes, respiratory tract, etc., and can also enter the blood and bone tissue through the skin to cause damage. At present, conventional hydrofluoric acid treatment is to rinse with running water. Hydrofluoric acid splashes easily during the rinsing process, causing harm to the body of patients and medical staff. In addition, porcelain restorations are usually small in size and light in weight, and are prone to falling, contamination or damage during the rinsing and drying process. Improper operation by nurses can lead to failure of bonding of porcelain restorations of patients, which seriously affects the patient's medical experience.

DETAILED DESCRIPTION

[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0035] It should be understood that in the description of the specification and claims of this application, if there are terms such as "first", "second", etc., they are only used to distinguish the objects described, and do not have any order or technical meaning. Therefore, the objects defined as "first", "second", etc. may explicitly or implicitly include one or more of the objects. In addition, "one" or "a" and similar words do not indicate a quantitative limitation, but indicate the existence of at least one, and "multiple" means no less than two.

[0036] In the description of the specification and claims of this application, if there are terms such as "upper", "lower", "horizontal" and the like indicating an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the application clearly and simply, and does not indicate or imply that the elements referred to must have a specific direction, be constructed and operated in a specific orientation. These directional terms are relative concepts, used for relative description and clarification, and may change accordingly according to the change in the orientation of the components in the drawings. For example, if the device in the figure is turned over, the elements described as "below" other elements will be positioned "above" other elements.

[0037] In the prior art, the surface treatment of glass-ceramic restorations often uses corrosive liquids such as hydrofluoric acid, which can selectively dissolve the glass matrix of glass-ceramic restorations, increase the bonding surface roughness, bonding area and surface activity. Figure 1 The figure shows a schematic diagram of the structure of a glass ceramic restoration, which includes a bonding surface 11 bonded to the user's tooth enamel and a non-bonding surface 12 facing away from the user's tooth enamel. Since the bonding surface 11 needs to be bonded to the user's tooth enamel, surface treatment of the glass ceramic restoration is necessary to increase the roughness, bonding area and surface activity of the bonding surface 11.

[0038] like Figure 2 The figure shows a schematic diagram of the structure of a hydrofluoric acid treatment device for a glass ceramic restoration, which includes: a cleaning mechanism 2 having a spray gun 21 for cleaning hydrofluoric acid on the surface of a glass ceramic restoration; a protective mechanism 3 having a closed protective cover 30, the surface of which is provided with an operating hole 34 for the spray gun to enter and exit the protective cover 30, and a plurality of glass ceramic restorations 1 can be movably connected in the protective cover 30, and the glass ceramic restorations switch the cleaning angle with the spray gun spray operation. By cleaning the surface of the glass ceramic restoration in the protective mechanism 3 with a spray gun, the dissolved glass matrix of the bonding surface 11 of the glass ceramic restoration can be quickly removed, so that the bonding surface 11 of the glass ceramic restoration has an uneven rough surface, thereby increasing the bonding strength between the bonding surface 11 of the glass ceramic restoration and the tooth enamel.

[0039] In a preferred embodiment of the present invention, a fixed disk 37 is provided in the protective cover body 30, and a plurality of ceramic restoration operating rods are movably connected to the fixed disk 37; a plurality of first drainage holes 371 are arranged in an array on the fixed disk 37, and the plurality of first drainage holes 371 are distributed around the ceramic restoration operating rod. By providing the fixed disk 37, a plurality of glass ceramic restorations can be installed on the protective cover body 30 at one time, which is convenient for cleaning the bonding surfaces 11 of multiple glass ceramic restorations or a plurality of glass ceramic restorations of one user, reducing the waiting time of the user and improving the user's dental restoration experience. In addition, since the ceramic restoration operating rod is movably connected to the fixed column, it is convenient for the glass ceramic restoration to turn and flip during the cleaning process. In addition to cleaning the bonding surface 11 of the glass ceramic restoration, multiple other surfaces of the glass ceramic restoration can also be cleaned to prevent the influence of residual hydrofluoric acid on other surfaces.

[0040] In a preferred specific embodiment of the present invention, the ceramic restoration operating rod 39 includes a sleeve portion 391 and an adsorption portion 392, a movable sleeve 372 is provided on the fixed disk 37, the movable sleeve 372 is clearance-matched with the fixed disk 37, the sleeve portion of the ceramic restoration operating rod is embedded in the movable sleeve 372, and rotates with the rotation of the movable sleeve 372; the adsorption portion of the ceramic restoration operating rod is adsorbed and connected to the non-bonding surface of the ceramic restoration. Due to the design of the movable sleeve, the sleeve portion rotates with the spray gun spraying operation. The ceramic restoration operating rod rotates with the rotation of the movable sleeve, which facilitates the cleaning of multiple areas of the glass ceramic restoration and avoids the obstruction of the surface area of ​​the glass ceramic restoration during the cleaning process. Since gas purging is required after water washing and cleaning, the design of the sleeve portion rotating with the spray gun spraying operation can quickly remove the residual liquid on each surface and air-dry the glass ceramic restoration. A more preferred embodiment of the present invention is that the glass ceramic restoration is fixed on the ceramic restoration operation rod. After cleaning and air drying, the ceramic restoration operation rod can be directly taken out from the movable sleeve, and the doctor can directly use it for bonding surface bonding operation, which simplifies the operation coordination between medical staff.

[0041] At present, conventional hydrofluoric acid treatment is to rinse with running water. During the rinsing process, hydrofluoric acid is prone to splashing, causing harm to the patients and medical staff. In addition, porcelain restorations are usually small in size and light in weight, and are prone to falling, contamination or damage during the rinsing and drying process. In the specific embodiment of the present invention, the protective mechanism 3 can effectively prevent hydrofluoric acid from splashing, protecting patients and medical staff from harm. Since the ceramic restoration operating rod can elastically adsorb the glass-ceramic restoration, the restoration can be effectively protected during the treatment of the ceramic restoration, avoiding the risk of the restoration falling and being lost. In the preferred specific embodiment of the present invention, each glass-ceramic restoration is adsorbed and fixed by the ceramic restoration operating rod. Due to the cooperation with the doctor's subsequent bonding operation, the glass-ceramic restoration can be fixed more stably by adsorption and fixation by the ceramic restoration operating rod.

[0042] In a preferred specific embodiment of the present invention, the diameter of the adsorption portion of the ceramic restoration operating rod is greater than the diameter of the sleeve portion of the ceramic restoration operating rod. The adsorption portion of the ceramic restoration operating rod is provided with an elastic adsorption body, and the elastic adsorption body contacts the ceramic restoration to adsorb the ceramic restoration, or; a medical adhesive is provided between the adsorption portion of the ceramic restoration operating rod and the ceramic restoration, and the adsorption portion of the ceramic restoration operating rod adsorbs the ceramic restoration through the medical adhesive. The present invention fixes the ceramic restoration by the adsorption portion of the ceramic restoration operating rod, and places the ceramic restoration at the front end of the ceramic restoration operating rod, which is convenient for subsequent doctors to perform bonding operations. Due to the setting of the adsorption portion of the ceramic restoration operating rod, the bonding surface of the glass ceramic restoration is set outward, and the ceramic restoration will not be damaged. Since the bonding surface of the glass ceramic restoration is tilted under the adsorption of the adsorption portion of the ceramic restoration operating rod, the glass ceramic restoration can be kept in a leaning state during the cleaning process, which is convenient for subsequent medical staff to operate. The water flow from the spray gun impacts the rough bonding surface of the ceramic restoration, which can drive the ceramic restoration operating rod to rotate in the protective mechanism. On the one hand, the water flow impacts the rough bonding surface of the ceramic restoration to quickly clean the bonding surface; on the other hand, the hydrofluoric acid and other corrosive liquids in the small pits in the rough bonding surface are quickly thrown out by the rotating water flow. In the subsequent air-drying process, the gas sprayed from the spray gun can also drive the ceramic restoration operating rod to rotate in the protective mechanism, and the water droplets remaining in the pits are quickly dried.

[0043] In a preferred specific embodiment of the present invention, the device further comprises: a waste liquid collection and storage mechanism, the protective mechanism 3 is connected to the waste liquid collection and storage mechanism, and the waste liquid collection and storage mechanism is configured to receive waste cleaned by the cleaning mechanism 2. In a more preferred embodiment, an anti-falling mechanism 38 is arranged between the waste liquid collection and storage mechanism and the protective mechanism 3, and the anti-falling mechanism 38 is provided with a second drainage hole 381, and the aperture of the second drainage hole 381 is smaller than the minimum outer diameter of the glass ceramic restoration; the aperture of the first drainage hole 371 is greater than or equal to the mesh aperture of the anti-falling mechanism 38; the aperture of the first drainage hole 371 is greater than the minimum outer diameter of the glass ceramic restoration. The waste liquid after cleaning is collected by the waste liquid collection and storage mechanism, and cleaning is performed after assembly, and the cleaning liquid splashes in the protective mechanism 3 and the waste liquid collection and storage mechanism, which will not affect external medical staff.

[0044] In a preferred specific embodiment of the present invention, the protective cover body 30 includes a first cover body 31 and a transparent body 32, one end of the first cover body 31 is hinged to the transparent body 32, and the other end is buckled and connected to the joint 35 provided on the transparent body 32, and a release button 36 is provided on the outside of the transparent body 32 for releasing the buckled state of the first cover body 31 and the transparent body 32, and opening the protective cover body 30; the fixed disk 37 is embedded in the storage bottle, and the anti-fall mechanism 38 is provided between the fixed disk 37 and the lower end of the storage bottle; the anti-fall mechanism 38 is fixedly connected to the fixed disk 37 at the side of the fixed disk 37. In order to facilitate the medical staff to take out the cleaned and air-dried glass ceramic restoration, the protective cover body 30 is set to be split, and the first cover body 31 and the transparent body 32 are buckled and connected, so that the medical staff can quickly open and take the glass ceramic restoration, thereby improving the convenience of the medical staff's work. On the other hand, the transparent body 32 can facilitate the medical staff to see the clean and air-dried situation inside the protective cover body 30 from the outside.

[0045] In another preferred specific embodiment of the present invention, the waste liquid storage mechanism 4 is a storage bottle, one end of the protective cover body 30 is hinged to the storage bottle, and the other end is buckled with the joint 35 provided on the transparent body to seal the storage bottle; a release button is provided on the outer side of the protective cover body 30 for releasing the buckling of the joint 35 on the storage bottle and the protective cover body 30. Through different buckling methods, medical staff only need to release the button to open the protective cover body 30, and the glass ceramic restoration can be taken out, which can be quickly applied to the corresponding patient object.

[0046] In a preferred specific embodiment of the present invention, the fixing plate 37 is embedded in the storage bottle, and the anti-falling mechanism 38 is between the fixing plate 37 and the lower end of the storage bottle; the anti-falling mechanism 38 is fixedly connected to the fixing plate 37 at the side of the fixing plate 37. In order to further prevent the glass ceramic restoration from falling, the anti-falling mechanism 38 is arranged between the fixing plate 37 and the storage bottle, so that the liquid can pass quickly during cleaning, and even if the glass ceramic restoration falls, it will only fall to the anti-falling mechanism 38.

[0047] In a preferred specific embodiment of the present invention, an elastic body (not shown) is arranged between the fixing plate 37 and the protective cover body 30; when the protective cover body 30 and the joint part 35 arranged on the transparent body are buckled to seal the storage bottle, the protective cover body 30 compresses the elastic body; when the buckling between the joint part 35 on the storage bottle and the protective cover body 30 is released, the elastic body rebounds and recovers. This makes it convenient for medical staff to open the protective cover body 30 after releasing the release button. The elastic body can automatically open the protective cover body 30 after the release button is released, which improves the convenience of medical staff to open the protective cover body 30.

[0048] In a preferred specific embodiment of the present invention, a dump outlet 41 is provided at the bottle mouth position of the inner wall of the storage bottle, and the joint 35 is provided with a second cover body 351, and the second cover body 351 corresponds to the dump outlet position to seal the dump outlet 41; when the other end of the protective cover body is buckled and sealed with the joint provided on the transparent body 32, the joint cooperates with the dump outlet to seal the dump outlet; a guide groove is provided along the dump outlet to facilitate the outflow of liquid toward the lower end of the storage bottle, and the width of the guide groove narrows from the lower end of the storage bottle to the bottle mouth direction of the inner wall of the storage bottle. The provision of the guide groove and the dump outlet 41 facilitates the discharge of the cleaning liquid after cleaning and air drying. During the pressurized flushing operation, the correspondence between the dump outlet 41 and the second cover body 351 can form a closed and airtight environment, which is convenient for pressurized water vapor flushing. The time for flushing the restoration is generally about 30 seconds, which meets the use requirements of medical staff.

[0049] The embodiment of the present invention is designed by a relatively closed hydrofluoric acid treatment device for glass-ceramic restorations. The protective cover body 30 can be a protective cover body including an upper operation hole 34 (with a protective cover 33). The transparent body does not block the nurse's sight, and a three-way gun can be used to rinse and blow dry through this hole; the middle part of the anti-fall mechanism 38 can adopt a Monel400 nickel-copper alloy mesh that can be embedded, which is convenient for the glass-ceramic restoration to fall; the lower part is a storage bottle, which can be transparent. All components are made of materials that are resistant to hydrofluoric acid corrosion. Except for the nickel-copper alloy net bag, all other components are made of PET plastic, and can be wiped and disinfected with alcohol for standby use. The anti-fall mechanism 38 can be sterilized at high temperature and high pressure.

[0050] The device can effectively prevent hydrofluoric acid from splashing, protecting patients and medical staff from harm; the device can effectively protect the restoration during the processing of the porcelain restoration, avoiding the risk of the restoration falling and being lost. The device has a simple structure, low manufacturing cost, and is easy to operate, which can improve the work efficiency of nurses.
