Description

Technical Field

[0001] This utility model belongs to the field of dental restoration technology, specifically relating to a special device for achieving 360° synchronous light curing when bonding artificial teeth and implant abutments outside the mouth. Background Technology

[0002] Currently, when dentists bond dental implant crowns and abutments outside the mouth, they need to hold the restoration with one hand and hold the light-curing lamp in the other, rotating it in a circle. Even slight instability can lead to uneven resin curing, affecting the overall bonding quality. Industrial ring-shaped curing machines can achieve 360° irradiation, but the ring-shaped curing agent is too large, three times the size of dental resin, and its wavelength range is too wide (380-500nm), making precise curing difficult and unsuitable for the small curing requirements of dental restorations. While some positioning jigs exist, these only fix the abutment and cannot simultaneously address the light irradiation issue, requiring additional operation of the light-curing machine, making the process cumbersome.

[0003] In summary, current curing technologies suffer from significant fluctuations in bond strength (measured shear strength differences reaching ±3.5 MPa), making them prone to microleakage. Furthermore, they cause high operator fatigue, with each bonding session taking an average of 2-3 minutes, leading to a restoration rejection rate exceeding 15%. Therefore, given the 20% annual increase in dental implant restorations, there is an urgent need for a specialized device that can simultaneously address both fixation stability and light uniformity. Utility Model Content

[0004] To address the technical problems of cumbersome operation and uneven curing in traditional handheld light-curing technology for extraoral bonding scenarios, this invention provides a specialized device for achieving 360° synchronous light curing when bonding artificial teeth and implant abutments extraorally. It is particularly suitable for the light-curing resin bonding process between abutments and artificial crowns in dental implant restorations, providing an efficient and precise curing device for the bonding of implant restorations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ring-shaped coaxial light curing device for external bonding of artificial tooth abutments, including a base fixing module, the base fixing module having a cylindrical structure, a curing hole at the center of the top of the base fixing module, and a threaded interface at the center of the bottom of the curing hole, the curing hole and the threaded interface being arranged concentrically.

[0006] An electric drive module is located on one side of the basic fixing module, which provides power to the UV ring curing lamp. The electric drive module contains a battery, which is electrically connected to a charging port on the electric drive module via a charging circuit board. An external power supply is connected to the charging port to charge the battery. The battery is also electrically connected to an electrode interface on the electric drive module via a switch. The switch controls the opening and closing of the electrode interface, thereby controlling the on / off state of the UV ring curing lamp.

[0007] The device also includes a UV ring curing lamp, which is electrically connected to the electrode interface through the lamp ring electrode. The central axis of the UV ring curing lamp coincides with the central axis of the threaded interface. The UV ring curing lamp is fixed on the lamp ring electrode by a positioning ring. The positioning ring is a U-shaped snap-fit ​​structure, and the UV ring curing lamp is elastically snapped in the positioning ring.

[0008] The top of the electric drive module has heat dissipation holes, which can dissipate the heat in the electric drive module in a timely manner.

[0009] The base fixing module has a cylindrical structure. The bottom of the base fixing module is equipped with a ring-shaped anti-slip silicone pad and a bottom mark. The ring-shaped anti-slip silicone pad can ensure that the base fixing module is in close contact with the operating table and avoids slipping; the bottom mark is used to indicate the functional parameters of the entire device.

[0010] Compared with the prior art, the specific beneficial effects of this invention are as follows: This invention, by arranging a UV ring-shaped curing lamp and a threaded interface, fixes the planting base through the threaded interface. The UV ring-shaped curing lamp provides 360° coaxial irradiation and curing of the planting base placed within the threaded interface, resulting in uniform curing and significantly improved bonding strength (increasing bonding strength by more than 20%). This invention significantly shortens the single operation time, greatly improving operational efficiency compared to traditional handheld operation. This invention achieves a significant improvement in energy utilization efficiency and reduces power consumption through precise wavelength matching. This invention is compatible with multiple mainstream planting systems, has wide adaptability, and can be widely promoted and applied. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] like Figure 1-6 As shown, a ring-shaped coaxial light-curing device for external bonding of artificial dental abutments includes a base fixation module 1, which is a cylindrical structure. The inner ring of the base fixation module 1 is made of high-strength aluminum alloy, and the outer shell of the base fixation module 1 is made of medical-grade ABS material to achieve a lightweight design. A curing hole is opened at the center of the top of the base fixation module 1, and a threaded interface 2 is opened at the center of the bottom of the curing hole. The curing hole and the threaded interface 2 are arranged concentrically.

[0020] An electric drive module 4 is provided on one side of the basic fixing module 1, which provides power to the UV ring curing lamp 5. The electric drive module 4 contains a battery, which is electrically connected to a charging port 11 on the electric drive module 4 via a charging circuit board. An external power supply is connected to the charging port 11 to charge the battery. The battery is electrically connected to an electrode interface 13 on the electric drive module 4 via a switch 10. The switch 10 controls the opening and closing state of the electrode interface 13, thereby controlling the on / off state of the UV ring curing lamp 5.

[0021] The electric drive module 4 adopts a standardized circuit scheme, with an MCP41010 digital potentiometer and a PIC16LF18 MCU as the core control module, paired with a TI TPS926xx series constant current LED driver, to achieve precise light intensity control of the 450nm±10nm UV lamp strip (adjustable from 800-1500mW / cm²). The system has a built-in 12V / 2000mAh lithium battery, which, according to actual testing, can support 25 full-power curing cycles of 40 seconds each. It is equipped with basic timing functions (1-60 seconds) and dual over-temperature protection (60℃ threshold + 0.5-second rapid power-off), fully complies with GB 9706.1 and YY 0505 medical electrical standards, and has passed ISO 10993 biocompatibility certification.

[0022] This device also includes a UV ring curing lamp 5. The wavelength of the UV ring curing lamp 5 is precisely controlled at 450nm±10nm, which perfectly matches the optimal curing band of dental resin. The minimum inner diameter of the UV ring curing lamp 5 is 8mm, and the maximum outer diameter of the UV ring curing lamp 5 is 30mm. The UV ring curing lamp 5 is electrically connected to the electrode interface 13 through the lamp ring electrode 12. The UV ring curing lamp 5 is fixed on the lamp ring electrode 12 by the positioning ring 7. The positioning ring 7 is a U-shaped snap-fit ​​structure, and the UV ring curing lamp 5 is elastically snapped in the positioning ring 7.

[0023] The top of the electric drive module 4 is provided with heat dissipation holes 8, which can dissipate the heat in the electric drive module 4 in a timely manner.

[0024] The bottom of the base fixing module 1 is provided with an annular anti-slip silicone pad 9 and a bottom mark 6. The annular anti-slip silicone pad 9 can ensure that the base fixing module 1 is in close contact with the operating table and avoid slipping; the bottom mark 6 is used to indicate the functional parameters of the entire device.

[0025] During operation, the basic fixation module 1 is placed on the workbench with a friction coefficient ≥0.8 to ensure the stability of the entire curing device. The screw 16 at the bottom of the implant abutment 3 is threaded into the threaded interface 2. The coaxiality error between the threaded interface 2 and the UV ring curing lamp 5 is ≤0.1mm to achieve zero-displacement curing. The retaining plate 15 of the implant abutment 3 is positioned inside the basic fixation module 1. Resin is applied to the top of the implant abutment 3, and the simulated artificial crown 14 is fastened onto the implant abutment 3. The switch 10 on one side of the electric drive module 4 is turned on, and the UV ring curing lamp 5 irradiates the implant abutment 3 360° to ensure that the resin in all parts of the implant abutment 3 cures synchronously. The entire curing process automatically stops after 40 seconds. After curing, excess residue on the surface is removed. The entire curing process is simple to operate and has strong clinical applicability.

[0026] When replacing planting base 3, the time interval is shortened to less than 10 seconds.
