Description

TECHNICAL FIELD

[0001] The utility model relates to the field of dental medical instruments, especially to a medicine slow-release abutment. BACKGROUND

[0002] With the improvement of living standards, oral problems attract more and more attention, and the implant dentistry industry is developing rapidly. The current implant dentistry process usually requires three steps: 1. Surgical implantation of implant; 2. Installation of temporary abutment; 3. Replacement of permanent abutment and installation of crown.

[0003] Therefore, the abutment is an intermediate structure connecting the lower implant and the upper crown, which is the part of the artificial implant exposed to the mucosa outside. It plays a very important role in connecting the upper and lower parts. For example, the existing utility model patent CN218128815U discloses a dental implant healing abutment, which comprises an abutment body and a central bolt. The central bolt vertically penetrates the abutment body. The abutment body comprises, from top to bottom, a crown support assembly, a transgingival assembly, an implant restoration platform assembly, and an implant connection assembly. The abutment, implant, and crown are connected.

[0004] However, in actual use of the abutment, it is found that during the implant dentistry treatment process, there is a large amount of bleeding, which may cause bacterial growth at the surgical site and form dental plaque, further causing peri-implantitis. Dental implant diagnosis and treatment require a 3-6 month treatment and repair period, which is a long and complex overall implantation period. There is a 43% possibility of infection of peri-implant mucositis and a 22% possibility of infection of peri-implantitis, which may cause more serious consequences such as bone resorption. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide a medicine slow-release abutment, which is provided with a cavity for placing medicine. The medicine is gradually precipitated out of the abutment through the medicine placing hole, which has an anti-inflammatory and bacteriostatic effect on the environment around the implant.

[0007] In at least one embodiment, the top of the abutment body is provided with an opening and a cap for sealing the opening. The cap comprises a baffle and an insertion column, the baffle is fixedly connected with the insertion column, the insertion column can be inserted into the cavity and is threadedly connected with the abutment body, and the baffle is blocked outside the abutment body; the medicine outlet hole is located below the insertion column. The bottom wall of the cavity is provided with a connecting hole, and the bottom of the insertion column is provided with a connecting column which is inserted into and threadedly connected with the connecting hole. The top of the cap is provided with an internal hexagonal recess.

[0008] In at least one embodiment, the medicine outlet hole has a plurality of medicine outlet holes which are arranged at intervals.

[0009] In at least one embodiment, the abutment body and the abutment connecting part are made of pure titanium material.

[0017] The utility model will be described in detail below with reference to the exemplary embodiments in the drawings. But it should be known that the utility model can be realized by various different forms, and should not be understood as being limited to the embodiments set forth herein. The embodiments are provided herein to make the disclosure of the utility model more complete and to fully convey the concept of the utility model to those skilled in the art.

[0018] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0019] The inventors addressed the drawback of existing dental implant healing abutment technologies, which can lead to bacterial growth at the surgical site. After careful analysis, they discovered that this problem primarily stems from the significant bleeding that occurs during implant treatment. This bleeding creates a moist and nutrient-rich environment at the surgical site, making it an ideal breeding ground for bacteria. These bacteria gradually accumulate and calcify, forming difficult-to-remove plaque. Plaque not only affects aesthetics but, more importantly, becomes a source of oral inflammation, potentially leading to peri-implantitis. Peri-implantitis is a serious complication that severely threatens implant stability and long-term survival. Furthermore, dental implant treatment and restoration are not instantaneous but require a relatively long and complex process, typically lasting 3 to 6 months. During this period, patients experience inconvenience and pain, and face a higher risk of infection. Statistics show that up to 43% of patients undergoing dental implantation may develop peri-implantitis, while 22% may suffer from more severe peri-implantitis. These infections not only prolong recovery time and increase treatment costs, but more importantly, they can lead to more serious consequences such as bone resorption, which will have a profound impact on the patient's oral health and overall quality of life. Based on this analysis, the inventors designed a drug-releasing abutment with a cavity for drug placement. The drug is gradually released into the abutment through a delivery hole, producing anti-inflammatory and antibacterial effects on the peri-implant environment.

[0020] like Figures 1 to 3 As shown, in one embodiment of this utility model, the drug-releasing abutment includes: an abutment body 1 having a cavity 11 for loading drug and a drug outlet 12, the cavity 11 communicating with the drug outlet 12; an abutment connecting part 2 located at the bottom of the abutment body 1 and used for connecting with the implant; the abutment body 1 and the abutment connecting part 2 are integrally formed. There are multiple drug outlets 12, spaced apart. Drug is released through the drug outlets 12 of the abutment body 1 to inhibit peri-implant bacteria, thereby improving symptoms.

[0021] The top of the abutment body 1 is provided with an opening and a cap 13 for sealing the opening. The cap 13 comprises a baffle 14 and an insertion column 15, the baffle 14 is fixedly connected with the insertion column 15, the insertion column 15 can be inserted into the cavity 11 and is threadedly connected with the abutment body 1, and the baffle 14 is blocked outside the abutment body 1; the medicine outlet hole 12 is located below the insertion column 15. The bottom wall of the cavity 11 is provided with a connecting hole, and the bottom of the insertion column 15 is provided with a connecting column 16, which is inserted into the connecting hole and is threadedly connected with it. The top of the cap 13 is provided with an internal hexagonal groove. The cap 13 is opened by using an internal hexagonal wrench, antibiotics can be placed in the abutment body 1, the opening of the abutment body 1 is sealed by using the cap 13, and the abutment body 1 is installed on the implant. After the patient goes back, the bacteriostatic drug will be gradually precipitated with chewing, and the patient can continue to be "treated" for a period of time after going home, which has an anti-inflammatory and bacteriostatic effect on the microenvironment around the implant. Generally, the treatment process lasts for 48 hours, and then the drug slow-release abutment is disassembled, and the patient is replaced with a normal healing abutment.

[0022] The abutment body 1 and the abutment connecting part 2 are made of pure titanium material. The dental abutment made of pure titanium material and coated with a special electroplated coating is designed to improve the biocompatibility, corrosion resistance, hardness and wear resistance of the abutment, promote bone integration, reduce bacterial adhesion and improve the aesthetic effect. These characteristics together ensure the stability and durability of the dental abutment, providing better treatment effect and comfort for the patient.

[0023] The abutment body 1 is cylindrical, and a plurality of medicine outlet holes 12 are uniformly distributed around the axis of the abutment body 1. The cap 13 is provided with an adjusting sleeve 17, the adjusting sleeve 17 is sleeved on the connecting column 16 and is fixedly connected with the insertion column 15, the outer diameter of the adjusting sleeve 17 is consistent with the inner diameter of the cavity 11, after the insertion column 15 is inserted into the cavity 11, the adjusting sleeve 17 can shield the medicine outlet hole 12; a plurality of adjusting holes 18 are provided on the adjusting sleeve 17 relative to the position of the medicine outlet hole 12, the number of the adjusting holes 18 is consistent with the number of the medicine outlet holes 12 and is uniformly distributed on the adjusting sleeve 17. By rotating the cap 13, the size of the medicine outlet hole 12 can be adjusted, so as to adjust the drug release speed.

[0024] All the above embodiments are exemplary but not limiting, and various modifications or variations made by those skilled in the art to the above described specific embodiments under the concept of the present application shall be within the protection scope of the present application.
