Description

Technical Field

[0001] This invention relates to the field of dental implant technology, and in particular to a luminescent dental implant. Background Technology

[0002] Currently, dental implantology faces the challenge of treating peri-implantitis and abutment inflammation. Inadequate disinfection of the implantation site and implant itself before placement can easily lead to reinfection and oral inflammation later on. Therefore, continuous disinfection after implantation is crucial. Studies have found that blue light with a wavelength of 400–480 nm can kill periodontal pathogens. Applying blue light during the treatment of peri-implantitis and abutment inflammation can significantly accelerate bacterial control and achieve good therapeutic results. Green light with a wavelength of 500–560 nm has excellent osteogenesis-promoting effects. After implantation and abutment placement, light stimulation can lead to strong osseointegration within three days, and new bone formation within thirty days is nearly twice that of the control group.

[0003] Based on the above research, an inventor has filed a patent application for a luminescent oral implant (application number 2018101459427). The light source can be built into a hollow oral implant and powered by a wireless power supply device. The wavelength of the light emitted by the light source can be set as needed, emitting light with a wavelength of 400-480nm. The oral implant is a translucent implant and abutment, or a perforated pure titanium implant and abutment, or a combination of both. Currently, the commonly used translucent implants and abutments are generally all-ceramic implants and abutments. However, in reality, all-ceramic implants and abutments have low light transmittance, and the internal space and power of the light source they can accommodate are limited. This significantly reduces the sterilization effect when the light reaches the bone, requiring an increased irradiation time to achieve the desired effect. This also leads to the need for wireless power supply... Prolonged power supply to the light source generates heat accumulation, leading to excessively high temperatures in the implant and abutment, causing patient discomfort. All-ceramic implants and abutments also lack chemically bonded groups with living bone tissue, making it difficult to achieve good osseointegration and resulting in poor initial and long-term stability. Pure titanium implants and abutments possess excellent biocompatibility and suitable bending strength. Light transmission via perforations in pure titanium implants and abutments results in minimal light intensity loss. However, since light travels in a straight line, the irradiated area is affected by the number and diameter of the perforations. To ensure the inherent strength of pure titanium implants and abutments, excessive perforations cannot be made, thus limiting the irradiated area and hindering sterilization. Therefore, there is an urgent need for a light-emitting dental implant to improve sterilization and promote osseointegration efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a luminescent dental implant to solve the problems mentioned in the background art. The specific technical solution is as follows:

[0005] To achieve the above and other related objectives, the present invention provides a luminescent dental implant, comprising an implant and abutment, a healing cap, and a wireless power supply device.

The implant and abutment 1 have a light guide channel 101. The implant and abutment 1 include a smooth transgingival portion 11 and a threaded bone portion 12. The bone portion 12 has multiple light guide holes 102. The transgingival portion 11 is threadedly connected to the healing cap 2. A built-in light source 4 is located on the lower side of the healing cap 2. The built-in light source 4 includes a wireless charging coil receiver 41, an LED chip 42, and a light guide post 43. The wireless charging coil receiver 41 is located inside the healing cap 2 and works in conjunction with the wireless power supply device 3. The wireless charging coil receiver 41 is electrically connected to the LED chip 42. The light guide post 43 is located on the lower side of the healing cap 2 and is used to seal the L… The LED chip 42 has a sealed capsule 5 inside the light guide channel 101. The sealed capsule 5 contains a photocurable light guide medium. The sealed capsule 5 can release the photocurable light guide medium under the pressure of the light guide column 43. The LED chip 42 includes green light beads 431 emitting wavelengths of 500-560nm and blue light beads 432 emitting wavelengths of 400-480nm. In some embodiments, the photocurable light guide medium is a medical UV curable adhesive, mainly composed of silane coupling agent and epoxy resin. After testing, the medical UV curable adhesive is non-cytotoxic and has passed the hemolysis test. It has been verified in mouse experiments that it will not cause an inflammatory reaction and is suitable for direct contact with the bone interface. In some embodiments, in order to further improve the light guiding performance, glass microspheres are also provided inside the medical UV curable adhesive.

[0022] In some embodiments, the sealing capsule 5 is made of a rigid transparent plastic sheet, so that when the light guide post 43 squeezes the sealing capsule 5, it can crush the sealing capsule 5 and release the photocurable light guide medium. In other embodiments, the sealing capsule 5 is made of rubber material, and the lower side of the light guide post 43 is provided with a puncture part 44, which is used to puncture the sealing capsule 5. As the light guide post 43 moves down, the photocurable light guide medium is squeezed out of the sealing capsule 5 and finally squeezed out of the light guide hole 102. The light is reflected by the medical UV curing adhesive and the glass microspheres, passes through the light guide hole 102 and acts on the bone tissue.

[0023] In some embodiments, the perforation portion 11 is made of all-ceramic material, the bone-drilling portion 12 is made of pure titanium material, the perforation portion 11 and the bone-drilling portion 12 are bonded together with medical adhesive, and the LED core 42 also includes a red light bead 433 for emitting a wavelength of 630-680nm, the red light bead 433 is arranged at a position corresponding to the perforation portion 11, and the green light bead 431 and the blue light bead 432 are arranged at positions corresponding to the bone-drilling portion 12.

[0024] In some embodiments, such as Figure 2 As shown, the wireless power supply device 3 includes a wireless charging coil transmitter 31, a wireless power supply buckle 32, and a water-cooling circulation device 33. The wireless power supply buckle 32 is 3D printed according to the 3D structure of the patient's teeth and gums. The wireless charging coil transmitter 31 is located inside the wireless power supply buckle 32. A water-cooling chamber 34 is provided inside the wireless power supply buckle 32. The water-cooling circulation device 33 is connected to the water-cooling chamber 34. The water-cooling chamber 34 is used to cool the gums and healing cap 2 during charging to reduce the heat generated during wireless charging.

[0025] During installation, the implant and abutment 1 are first drilled into the oral cavity implantation site. The sealing capsule 5 is placed into the light guide channel 101, the light guide post 43 is inserted into the light guide channel 101, and the healing cap 2 is screwed into the perforated gingival portion 11. The healing cap 2 pushes the light guide post 43 downwards, squeezing the sealing capsule 5 and releasing the light-cured light guide medium. The light-cured light guide medium also contains glass microspheres for light scattering. The light-cured light guide medium is squeezed out of the sealing capsule 5 and finally squeezed out of the light guide hole 102, contacting the bone tissue. The light then enters the medical field. The UV-cured adhesive and the reflection of the glass microspheres pass through the light guide hole 102 and act on the bone tissue, which can greatly increase the area of ​​the bone tissue illuminated by the light. When in use, the wireless power supply buckle 32 is fastened to the teeth. At this time, the wireless charging coil transmitter 31 and the wireless charging coil receiver 41 are opposite each other to provide wireless power. The LED light core 42 emits blue light, green light and red light. The blue light sterilizes and cures the light guide medium, the green light promotes bone healing, and the red light passes through the gingival sulcus 11 to reduce inflammation of the gums. The effect is good.
