AI Technical Summary
[0003]在现有的种植牙基台结构中,多数采用整体式设计,牙冠安装座、对接部分与种植体连接部位通常为一体化成型,这种设计虽然在一定程度上保证了基台的整体强度,但当基台出现螺丝孔滑丝、陶瓷崩裂等局部损坏情况时,由于整体结构无法拆分,只能将整个基台进行更换,这不仅大幅增加了患者的治疗成本,也造成了医疗资源的浪费,此外,现有基台在与种植体连接部位因装配精度问题存在一定间隙,这样食物残渣容易在基台与种植体的接缝处积聚,而这些部位清洁难度较大,长期以往容易滋生细菌,引发口腔卫生问题,因此,亟需一种新型的种植牙基台结构,以解决现有技术中存在的维护成本高、口腔卫生难以保障等问题
[0012]通过设置的拆装结构,牙冠安装座、连接套和对接圆台采用独立拆装设计,通过螺纹连接组合成基台整体,当出现螺丝孔滑丝、陶瓷崩裂等局部损坏情况时,无需更换整个基台,仅替换受损模块即可,大幅降低了维护成本,提升了产品的经济性和实用性。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental implant abutment technology, specifically a dental implant abutment. Background Technology
[0002] With the continuous development of oral medicine technology, dental implants, as an effective means of restoring missing teeth, have been widely used in clinical practice due to their high stability and good aesthetics. As a key component connecting the implant and the crown, the structural design and performance of the dental implant directly affect the lifespan of the implant and the patient's experience.
[0003] Most existing dental implant abutment structures adopt a monolithic design, where the crown mounting base, docking portion, and implant connection are typically molded as a single unit. While this design ensures the overall strength of the abutment to a certain extent, when local damage occurs such as stripped screw holes or ceramic chipping, the entire abutment must be replaced because the monolithic structure cannot be disassembled. This not only significantly increases the patient's treatment costs but also wastes medical resources. Furthermore, existing abutments have gaps at the implant connection due to assembly precision issues, allowing food debris to accumulate at the joint. These areas are difficult to clean and can easily breed bacteria over time, leading to oral hygiene problems. Therefore, a new type of dental implant abutment structure is urgently needed to solve the problems of high maintenance costs and difficulty in ensuring oral hygiene in existing technologies. Utility Model Content
[0004] The purpose of this invention is to provide a dental implant abutment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dental implant abutment, comprising a crown mounting base, a mating frustum, and a threaded post. The mating frustum is disposed below the crown mounting base, and the threaded post is fixed to the lower end face of the mating frustum. A disassembly and assembly structure is provided between the crown mounting base and the mating frustum. The disassembly and assembly structure includes a connecting sleeve disposed between the crown mounting base and the mating frustum. A first threaded post is fixed to the lower end of the crown mounting base, and a second threaded post is fixed to the upper end of the mating frustum.
[0006] Preferably, the upper end of the connecting sleeve is provided with a first threaded groove, and the interior of the connecting sleeve is provided with a second threaded groove.
[0007] Preferably, the first threaded platform is threadedly connected to the first threaded groove of the connecting sleeve, and the second threaded platform is threadedly connected to the second threaded groove of the connecting sleeve.
[0008] Preferably, the lower end of the connecting sleeve has a sealing cover opening, and the upper end of the mating frustum extends into the sealing cover opening of the connecting sleeve.
[0009] Preferably, a sealing cover is fitted and fixed on the outer surface of the crown mounting base, and the sealing cover is positioned above the connecting sleeve.
[0010] Preferably, the connecting sleeve, the first threaded groove, and the sealing cover are connected together, and an anti-slip pad is fixed to the upper end of the mating platform, with the lower end of the first threaded platform abutting the upper surface of the anti-slip pad.
[0011] This invention provides a dental implant abutment, which has the following advantages compared with the prior art:
[0012] With its designed disassembly and assembly structure, the crown mounting base, connecting sleeve, and mating frustum are independently designed for disassembly and assembly. They are assembled into a base unit through threaded connections. When local damage occurs, such as stripped screw holes or ceramic chipping, it is not necessary to replace the entire base unit; only the damaged module needs to be replaced. This significantly reduces maintenance costs and improves the product's economy and practicality.
[0013] With the addition of a connecting sleeve and a mating platform, the sealing cap at the lower end of the connecting sleeve can be fitted onto the upper part of the implant to seal the connection between the implant abutment and the implant. This effectively prevents food debris from accumulating at the joint, reduces oral hygiene problems caused by inconvenient cleaning, helps maintain oral health, and lowers the risk of postoperative infection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a dental implant abutment, including a crown mounting base 1, a mating frustum 2, and a threaded post 3. The mating frustum 2 is disposed below the crown mounting base 1, and the threaded post 3 is fixed to the lower end face of the mating frustum 2. A disassembly and assembly structure 4 is provided between the crown mounting base 1 and the mating frustum 2. The disassembly and assembly structure 4 includes a connecting sleeve 5, which is disposed between the crown mounting base 1 and the mating frustum 2. A first threaded platform 8 is fixed to the lower end of the crown mounting base 1, and a second threaded platform 9 is fixed to the upper end of the mating frustum 2. The connecting sleeve 5 enables a detachable connection between the crown mounting base and the mating frustum. The abutment is threaded to the first threaded platform 8 and the second threaded platform 9 through the first threaded groove 6 and the second threaded groove 7, respectively, forming a "modular" assembly structure.
[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the upper end of the connecting sleeve 5 is provided with a first threaded groove 6, and the interior of the connecting sleeve 5 is provided with a second threaded groove 7. The first threaded platform 8 is threadedly connected to the first threaded groove 6 of the connecting sleeve 5, and the second threaded platform 9 is threadedly connected to the second threaded groove 7 of the connecting sleeve 5.
[0022] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the lower end of the connecting sleeve 5 is provided with a sealing cover 10, the upper end of the docking frustum 2 extends into the sealing cover 10 of the connecting sleeve 5, and a sealing cover plate 11 is fixedly fitted onto the outer surface of the crown mounting base 1. The sealing cover plate 11 is positioned above the connecting sleeve 5. The opening structure at the lower end of the connecting sleeve 5 is fitted onto the upper part of the implant to form a physical barrier, sealing the connection between the abutment and the implant, improving the overall sealing performance, reducing food retention and bacterial growth caused by gaps, and reducing the risk of complications such as periodontitis.
[0023] Further as Figure 1 As shown, it is worth noting that the connecting sleeve 5, the first threaded groove 6, and the sealing cover 10 are connected. The upper end of the mating platform 2 is fixed with an anti-slip pad 12, and the lower end of the first threaded platform 8 is attached to the upper surface of the anti-slip pad 12.
[0024] This solution has the following working process: Before use, the docking frustum 2 is screwed into the second threaded groove 7 of the connecting sleeve 5 through the second threaded platform 9, while the crown mounting seat 1 is screwed into the first threaded groove 6 of the connecting sleeve 5 through the first threaded platform 8. In this way, the crown mounting seat 1, the connecting sleeve 5, the docking frustum 2 and the threaded post 3 form a dental implant abutment as a whole. Due to this three-part independent disassembly and assembly design, if the screw hole is stripped or the ceramic is broken and a certain part is damaged, only the damaged module can be replaced, thereby greatly reducing maintenance costs.
[0025] When the threaded post 3 is screwed into the implant thread, the mating frustum 2 is placed into the implant. At this time, the sealing cover 10 of the connecting sleeve 5 is fitted onto the upper part of the implant. In this way, the connecting sleeve 5 can seal the connection between the implant abutment and the implant, thereby reducing the trouble of food residue accumulating at the joint and making it difficult to clean.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Although embodiments of this utility model have been shown and described, this does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model. Regarding the embodiments of this utility model, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
