Description

Smart dentures with embedded thin-film sensors fabricated using femtosecond lasers, their manufacturing method, and health monitoring system

[0001] The present invention relates to a smart denture having a built-in thin film temperature sensor manufactured by a femtosecond laser pulse pattern for elderly health management, and a manufacturing method thereof.

[0002] In general, when a tooth or the tissue surrounding the tooth is damaged, prosthetic treatment using artificial prosthetics is used to restore the function and aesthetics of the tooth. If one or more teeth are partially damaged, a crown is made to cover the upper part of the damaged tooth and used as a prosthesis. However, if one or more teeth are missing and missing, a fixed partial denture, or bridge, is made by connecting the teeth on both sides to the missing part using the surrounding teeth as a pillar. If there are many missing teeth, dentures or partial dentures are used.

[0003] Recently, implants have become more popular than bridges due to the prevention of abutment damage and the declining cost of implants. Implants are also a viable option for those with numerous missing teeth. However, if implants are not feasible due to financial constraints, oral health, bone health, or systemic health, dentures may be the only option.

[0004] The use of these dentures is increasing as modern society moves beyond an aging society to a super-aged society, and their use is increasing rapidly as government support for dentures increases.

[0005] The majority of those who use the aforementioned dentures are elderly. Among these elderly individuals are those with dementia, those with potential dementia, and those with a medical history. This number is bound to increase. In particular, those with poor general health or bone health are often elderly, a problem that is becoming increasingly serious in an aging society.

[0006] However, dementia patients, potential dementia patients, the general public with a medical history, and especially the elderly who use dentures like the above have difficulty visiting the dentist regularly, making it difficult for them to receive dental clinic care for dentures. As a result, the lifespan of dentures is shortened, which inevitably increases the burden of denture replacement or repair on users.

[0007] Furthermore, the aging population and the rise in the number of people living alone are emerging as major social issues, and their health is becoming a growing social and economic burden. Monitoring their health and activities can prevent sudden accidents and, through this, reduce social costs. Among the aforementioned issues, financial constraints are likely to be a significant factor for those living alone. Therefore, the importance of dentures is all the more crucial.

[0008] People who live alone, are in poor health, or have financial difficulties making regular visits impossible are all subject to constant monitoring.

[0009] Therefore, there was a need to develop smart dentures that can be constantly monitored by attaching sensors to dentures that are worn all the time, measure changes in the wearer's body temperature through monitoring through the dentures, and identify patterns of temperature changes within the oral cavity to check eating habits and the wearer's level of activity.

[0059] Figure 6 illustrates a flowchart of a health monitoring method according to an embodiment of the present invention.

[0060] Hereinafter, the configuration, function, manufacturing method, and health monitoring method of a smart denture having a thin film sensor manufactured using a femtosecond laser according to an embodiment of the present invention will be described.

[0061] FIG. 1 is a photograph of a smart denture having a thin film sensor manufactured using a femtosecond laser according to an embodiment of the present invention.

[0062] As illustrated in FIG. 1, according to the smart denture (1) according to the embodiment of the present invention, the dental resin applied to the denture itself is used as a substrate (10), or a thin film sensor (2) is manufactured and installed on one surface of the denture itself made of dental resin to measure the wearer's body data, and such measurement data can be transmitted to a set user terminal or cloud system for monitoring.

[0063] That is, the smart denture (100) of the present invention includes a thin film type sensor (2) provided on one side of the surface of the smart denture.

[0064] A sensor (2) according to an embodiment of the present invention is configured to include a substrate (10) attached to one side of a denture, a deposition layer (20) deposited on the substrate (10), and a circuit pattern portion (30) in which a circuit pattern is formed by partially removing the deposition layer (20).

[0065] The circuit pattern portion (30) according to the embodiment of the present invention is manufactured through a laser printing method by irradiating a femtosecond laser pulse to the deposition layer (20) through a femtosecond laser system (100).

[0066] The deposition layer (20) according to an embodiment of the present invention may be a gold deposition layer.

[0067] Additionally, the substrate (10) according to an embodiment of the present invention is composed of dental resin (e.g. PMMA).

[0068] FIG. 2 illustrates a flow chart of a method for manufacturing a smart denture having a built-in thin film sensor manufactured using a femtosecond laser according to an embodiment of the present invention.

[0069] FIG. 3a is a perspective view of a substrate composed of dental resin according to an embodiment of the present invention. FIG. 3b is a perspective view of the substrate in FIG. 3a after gold has been deposited. FIG. 3c is a perspective view of a circuit pattern portion patterned using a femtosecond laser pulse in FIG.

[0070] The manufacturing of a sensor (2) according to an embodiment of the present invention includes a step (S10) of preparing a substrate (10) composed of a flexible dental resin in a thin film form, a step (S20) of depositing a circuit material (e.g., gold) on the substrate (10) to form a deposition layer (20), and a step (S30) of irradiating the deposition layer (20) with a femtosecond laser pulse using a femtosecond laser system (100) to produce a circuit pattern portion (30) having a specific pattern through a laser printing method.

[0071] As mentioned above, the sensor (2) according to the embodiment of the present invention may be a temperature sensor, the deposition layer (20) may be gold deposition, and the dental resin may be PMMA.

[0072] That is, the sensor (2) is manufactured by using a laser printing method on a gold-covered dental resin, maintaining the sensor area and removing the boundary area using a femtosecond laser. In this process, a thin gold film is deposited on the prepared dental resin sample, and then the remaining material is removed using a femtosecond laser, leaving only the sensor.

[0073] Among synthetic plastics with diverse physical properties, this sensor was built on dental resin, a technology used in 3D printing and milling to manufacture dental prosthetics, rather than on the substrate commonly used in semiconductors. This allows the sensor to be built on a material with identical physical properties, potentially offering advantages in physical properties like elasticity and flexibility when attached to an actual device.

[0074]

[0075] Fig. 4 illustrates a configuration diagram of a femtosecond laser system according to an embodiment of the present invention. Fig. 5 illustrates a flowchart of a patterning method using a femtosecond laser system according to an embodiment of the present invention.

[0076] A femtosecond laser system (100) according to an embodiment of the present invention is configured to include an optical fiber femtosecond laser generator (110), a quarter-wave plate (111), a first half-wave plate (112), a polarizing beam splitter (113), a beam block (114), and a second half-wave plate (115) sequentially provided in a laser emission path.

[0077] And it is configured to include an F-theta lens (130) that focuses the laser beam transmitted through the second half-wave plate (115) onto the deposition layer (20).

[0078] It also comprises a galvano scanner equipped with a computer-programmed galvano mirror (120) that is installed between the second half-wave plate (115) and the F-theta lens (130) and performs raster scanning.

[0079] Therefore, a femtosecond laser pulse is generated from the optical fiber femtosecond laser generator (110) (31). The optical fiber femtosecond laser generator (110) emits a 240 to 260 fs pulse with a near-infrared wavelength of 1000 to 1100 nm and a repetition rate of 190 to 210 KHz.

[0080] After a femtosecond laser pulse passes through a quarter-wave plate (111) and is circularly polarized, it is polarized into P-wave and S-wave through a first half-wave plate (112), and only the polarized waves that pass through a polarizing beam splitter (113) follow the optical path, while the remaining polarized waves are reflected by the polarizing beam splitter (113) and absorbed by a beam block (114). Then, it passes through a second half-wave plate (S32), is reflected by a mirror (116), and raster scanning is performed through a galvano scanner composed of a computer-programmed galvano mirror (120) (S33).

[0081] And, an elliptical laser beam focused on the deposition layer (20) is irradiated through the F-theta lens (130) (S34).

[0082] Additionally, the control unit can control the degree of polarization and laser output by controlling the polarizer.

[0083] These elliptical laser beams can be 72 to 82 * 66 to 76 elliptical beams, and are irradiated onto the deposition layer at a scanning speed of 25 to 35 mm / s and a laser power of 2.5 to 3.5 W.

[0084] In a specific embodiment of the present invention, an ytterbium-doped fiber femtosecond laser generator (110) emits a 255 fs pulse train at a near-infrared wavelength of 1040 nm and a repetition rate of 201.5 kHz.

[0085] The polarization state and laser output of a femtosecond laser are controlled using a quarter-wave plate (111), a first half-wave plate (112), a polarizing beam splitter (113), and a second half-wave plate (115). The experiment was performed under conditions of a scanning speed of 30 mm / s and a laser output of 3 W.

[0086] This sensor fabrication method can form a circuit without damaging the surface of dental resin (e.g., PMMA). Damage to dental resin can cause adverse effects such as deterioration of physical properties or cracking, so these adverse effects can be minimized.

[0087] Finally, in the embodiments of the present invention, a mask was not used. The sensor fabricated in this device was created using a laser, eliminating the need for a mask. This allows for considerable freedom in sensor size and design configuration, depending on intraoral conditions, and allows for rapid sensor formation.

[0088] The manufactured temperature sensor (2) exhibits a fast response time and strong protection against external pressure and water, ensuring durability.

[0089]

[0090] Figure 6 illustrates a flowchart of a health monitoring method according to an embodiment of the present invention.

[0091] A health monitoring system according to an embodiment of the present invention includes smart dentures incorporating a thin-film sensor manufactured using the aforementioned femtosecond laser (S100). Data measured by the smart denture sensors are transmitted to a preset user terminal or cloud system via the smart denture transmission module (S200). The analysis tool then analyzes this measurement data to analyze and monitor the wearer's health.

[0092] As mentioned above, if the sensor is a temperature sensor, the measurement data is temperature data, and the analysis means identifies the temperature change pattern in the oral cavity and analyzes eating habits, the wearer's activity level, disease, infection, and inflammation to generate analysis data (S300).

[0093] And these analysis means classify and store measurement data and analysis data according to time for each wearer, and the measurement data and analysis data are shared with the medical service system and used as treatment data (S400).

[0094]

[0095] Therefore, according to the smart dentures having a built-in thin film temperature sensor manufactured using a femtosecond laser according to an embodiment of the present invention, the manufacturing method thereof, and the health monitoring system, the sensor is attached to the dentures that are worn all the time, enabling constant monitoring, and the change in the body temperature of the wearer can be measured through monitoring through the dentures, and also the pattern of temperature change in the oral cavity can be identified, enabling the eating habits or the level of activity of the wearer to be confirmed.

[0096] And according to the smart dentures, the manufacturing method thereof, and the health monitoring system having a built-in thin film temperature sensor manufactured using a femtosecond laser according to an embodiment of the present invention, the weight of the dentures is hardly increased, and the function of the dentures in the oral cavity is not interfered with even after attachment, so that the function as a sensor as well as a prosthesis is not impaired.

[0097] In addition, according to the smart dentures, manufacturing method thereof, and health monitoring system having a built-in thin film temperature sensor manufactured using a femtosecond laser according to an embodiment of the present invention, it is possible to prevent sudden accidents by monitoring health and activity, thereby reducing social costs, and applying continuous body temperature monitoring to various fields.
