Description

Technical Field

[0001] The present invention relates to denture processing technology, and particularly to a vibrating porcelain chalk for porcelain application on dentures and a porcelain application method thereof.

Background Art

[0002] In clinical medicine, after a person's teeth fall out due to age or disease, dentures need to be installed for treatment, using dentures to replace the teeth. The processing of dentures is very particular, not only requiring attention to the aesthetic degree of the dentures, but also controlling the safety quality of the dentures.

[0003] The existing manufacturing process of dentures generally involves manually or automatically making a wax pattern, then casting, manually applying porcelain, and then turning the porcelain, and finally completing the processing of the dentures. Among them, applying porcelain to the denture is a relatively important step in denture processing. Applying porcelain means piling up porcelain powder to form the shape of a porcelain tooth and sintering it in a porcelain furnace to form an initial porcelain tooth. When applying porcelain, first clean the denture model, then weigh the porcelain powder, mix it with an adhesive to adjust the dryness and wetness of the porcelain clay, then hold a pair of pliers and a porcelain application pen in both hands respectively. One hand holds the denture model with the pliers, and the other hand holds the porcelain application pen tightly. Use the hairy tip at the front end of the porcelain application pen to dip into the porcelain powder clay with a certain dryness and wetness, and continuously pile up the porcelain powder clay on the denture model fixed by the pliers. And during the process of piling up and modifying the porcelain powder clay, it is necessary to continuously use the porcelain application pen held by hand or other vibrating striking rods. The porcelain application personnel control the strength according to experience and strike the pliers held by the other hand. Through appropriate vibration strength and frequency, the porcelain powder clay loosely applied on the denture model is shaken off, ensuring that the porcelain powder clay piled up on the denture model has appropriate adhesive compactness and thickness uniformity on the same plane, so as to form a uniformly thick and dense porcelain layer on the surface of the denture model by applying porcelain powder.

[0004] For the existing manual method of applying porcelain to dentures, due to the multi-station joint operation of manual labor, the process is complex and the preparation is poor. Because it is impossible to perform all-round acquisition and porcelain application on the denture, not only is the efficiency low, a large amount of porcelain powder is wasted, but also the strength of the denture product is insufficient, the finished product is poor, the product quality is reduced. At the same time, multi-station joint porcelain application and the inability to perform precise and uniform porcelain application on the denture reduce the aesthetics and practicality of the denture. Moreover, the accuracy of manual porcelain application depends too much on the proficiency and experience judgment of the operator, resulting in uneven thickness or easy detachment of the adhered porcelain powder on the same plane of the same denture, increasing the defect rate in the production process of applying porcelain to the denture and wasting a large amount of manpower and material resources.

Summary of the Invention

[0005] The present invention provides a vibrating porcelain chalk for porcelain application on dentures and a porcelain application method thereof, which have an integrated design of porcelain powder dipping and porcelain powder shaking off, with controllable vibration frequency and vibration strength, effectively improving the thickness uniformity and adhesive compactness of porcelain application on the denture.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The vibrating porcelain chalk for denture porcelain application, such as Figures 1 to 3As shown in the figure, it includes a tuft component 1 and a pen barrel body 2. The tuft component 1 is used to dip porcelain powder paste during the process of building and modifying the porcelain powder paste on the denture model, and to paint the porcelain powder paste on the surface of the denture model.

And a sealing ring 3 is sleeved at the threaded connection between the tuft component 1 and the pen barrel body 2; among them, the pen barrel body 2 is a hollow cylindrical body that is convenient to hold. An installation hole 4 for inserting and fixing the tuft component 1 is provided at the front end of the pen barrel body 2. A battery 5, a control board 6, and an eccentric wheel motor 7 are sequentially installed and fixed in the hollow cavity of the pen barrel body 2 from the rear to the front. The eccentric wheel motor 7 is a DC drive motor with a rotational speed of 11000 ± 3000 rpm / min. The battery 5 is a 3.7V polymer lithium-ion battery, and a protection circuit for overcharging protection of the battery 5 is provided on the control board 6. The battery 5, the control board 6, and the eccentric wheel motor 7 are electrically connected through wires; a switch component (not shown in the figure) that is electrically connected to the control board 6 and is used to control the start and stop of the eccentric wheel motor 7 and vibrate at a certain frequency is provided in the hollow cavity of the pen barrel body 2. In this embodiment, the switch component is a gravity sensor switch provided on the control board 6 in the hollow cavity of the pen barrel body 2. When the pen barrel body 2 is flipped 180°, the gravity sensor switch automatically controls the start of the eccentric wheel motor 7 through the control board 6 and vibrates at a certain frequency.

[0041] During use, after the pen barrel body 2 is rotated 180°, the eccentric wheel motor 7 is started through the switch component. The eccentric wheel motor 7 and the pen barrel body 2 vibrate continuously and synchronously at a certain frequency. The middle and rear parts of the vibrating pen barrel body 2 touch the pliers used to hold the denture model to evenly vibrate and shake off the porcelain powder paste that is loosely applied on the denture model. The entire production process is simple, highly operable, and has good consistency, solving the technical problem of unstable production quality in the traditional process, ensuring uniform porcelain application thickness, strong adhesion between the porcelain powder and the denture model, and the porcelain powder will not fall off easily, effectively improving the product quality.

[0042] Continue as Figures 1 to 3 As shown in the figure, the pen barrel body 2 includes a pen tail rod barrel 20 and a grip barrel 21. A sealing ring 3' is sleeved between the pen tail rod barrel 20 and the grip barrel 21. The pen tail rod barrel 20 and the grip barrel 21 are fixedly connected by threads. Both the pen tail rod barrel 20 and the grip barrel 21 are made of aluminum alloy metal barrels. The tuft component 1 is inserted and fixed in the installation hole 4 at the front end of the grip barrel 21. As Figure 4 shown in the figure, a magnetic charging interface for connecting to an external charging connector and charging the battery 5 is also provided at the bottom end of the pen tail rod barrel 20; of course, as Figure 5As shown in the figure, a plug-in charging interface for charging the battery 5 by connecting to an external charging connector may also be provided at the bottom end of the pen barrel 20 of the pen barrel body 2. Alternatively, a magnetic charging interface or a plug-in charging interface for charging the battery 5 by connecting to an external charging connector may be provided on the side wall of the pen tail of the pen barrel body 2.

[0043] In addition, different from this embodiment, the switch assembly may be slidably connected to the outer wall of the pen barrel body 2 and has a sliding switch button for controlling the start and stop of the eccentric wheel motor and three sliding switch buttons for controlling the eccentric wheel motor to switch gears from low frequency, medium frequency to high frequency. The sliding switch button is directly electrically connected to the control board through a wire. Alternatively, the switch assembly is a radio frequency controller provided in the hollow cavity of the pen barrel body 2. The radio frequency controller is electrically connected to the control board, and a remote controller for wireless communication with the radio frequency controller and controlling the start and stop of the eccentric wheel motor and the three gear switches of the eccentric wheel motor from low frequency, medium frequency to high frequency is provided outside the corresponding pen barrel body 2.

[0044] The method for applying porcelain to the denture includes the following steps:

[0045] Step 1: Hold the pen barrel body 2 of the vibrating porcelain pen, wet it with clear water using the hair head assembly 1 at the front end, and then dip it into the porcelain powder mud.

[0046] Step 2: Stack and decorate the porcelain powder mud on the surface of the denture model clamped by the pliers.

[0047] Step 3: Then, turn the pen barrel body 2 by 180°, start the eccentric wheel motor 7 through the switch assembly, and transmit continuous synchronous vibration of the pen barrel body 2 at a certain frequency; when the switch assembly is a gravity sensor switch on the control board 6 provided in the hollow cavity of the pen barrel body 2, after the pen barrel body 2 is turned by 180°, the gravity sensor switch automatically controls the start of the eccentric wheel motor 7 and vibrates at a certain frequency through the control board 6.

[0048] Step 4: The middle and rear parts of the vibrating pen barrel body 2 touch the pliers for clamping the denture model, and under the control of the operator, evenly vibrate and shake off the porcelain powder mud that is loosely applied to the denture model.

[0049] Step 5: Continuously repeat the above steps to continuously stack and decorate the porcelain powder on the upper surface of the denture model, forming a porcelain layer with uniform thickness and density on the same plane.

[0050] Of course, in Step 3, when the switch assembly is a sliding switch button slidably connected to the outer wall of the pen barrel body 2, the operator manually controls the sliding switch button to control the start and stop of the eccentric wheel motor and the frequency of switching gears from low frequency, medium frequency to high frequency, and adjusts the vibration frequency of the pen barrel body according to the specific situation during porcelain application.

[0051] Through the above process steps, an electrically controlled porcelain application pen is used. The middle and rear parts of the vibrating pen body are in contact with the pliers for clamping the denture model. Under the control of the operator, the porcelain powder mud loosely applied on the denture model can be evenly vibrated and shaken off, ensuring that the porcelain application on the surface of the denture model is uniform and compact, forming a porcelain layer with a uniform thickness and a dense adhesion on the same plane. This avoids errors in manual porcelain application or excessive dependence on the operator's proficiency and experience judgment, and also avoids waste of porcelain powder, saving a large amount of manpower and material resources.
