Description

Technical Field

[0001] This invention belongs to the field of dental implant technology, specifically a multi-threaded dental implant. Background Technology

[0002] Dental implants, as devices that are implanted into the alveolar bone to support dental restorations, have a rich historical, social, and technological background in their development.

[0003] Historically, humanity's exploration of tooth restoration has a long history. During the ancient Egyptian and Mayan civilizations, people attempted to implant materials such as shells and stones into the jawbone to replace missing teeth, but due to a lack of scientific evidence, the success rate was extremely low. It wasn't until 1952 that Swedish scientist Johannes Brenmark discovered osseointegration, the phenomenon that titanium metal can form a strong and stable bond with bone tissue, laying the theoretical foundation for the development of modern dental implants. The first successful modern dental implant surgery in 1965 marked the beginning of the modern era for dental implant technology.

[0004] In terms of social context, the aging population has exacerbated the problem of tooth loss. As physiological functions decline, tooth loosening and loss are common among the elderly, leading to a significant increase in the demand for dental restoration. Dental implants, as an ideal restorative method, can effectively improve chewing function and quality of life in the elderly. Simultaneously, with rising living standards, people are paying increasing attention to oral health and aesthetics. Tooth loss affects chewing, pronunciation, and facial aesthetics, leading more and more people to choose dental implants to restore missing teeth and improve oral function and appearance.

[0005] In terms of technological background, advancements in materials science have provided strong support for the development of dental implants. Modern dental implants primarily utilize biocompatible materials such as titanium and titanium alloys. These materials are highly corrosion-resistant, bioactive, and can form a tight osseointegration with the alveolar bone, ensuring long-term implant stability. New ceramic materials are also gradually being applied, with their aesthetics and biocompatibility gaining widespread recognition. The development of imaging technology is also crucial. CT scans and cone-beam computed tomography (CBCT) allow dentists to clearly understand the morphology, density, and anatomical structure of the patient's alveolar bone, providing precise guidance for implant placement and improving surgical success rates and safety. Furthermore, continuous improvements in surgical techniques have reduced the trauma and time of dental implant surgery, and accelerated postoperative recovery. For example, the application of minimally invasive implant techniques and immediate implantation techniques reduces patient suffering and the number of visits. With historical accumulation, driven by social needs, and supported by technological advancements, dental implants have continuously developed and improved, bringing good news to numerous patients with missing teeth.

[0006] In current dental practice, the implantation process for dental implants can present challenges for patients with osteoporosis, especially older patients. This is because osteoporotic patients have lower bone density and are less dense, which can lead to insufficient stability of the implant after placement. Particularly in the initial stages after implantation, the implant may loosen or even fall out in some cases because the bone tissue has not yet fully integrated with it. This not only affects the treatment outcome but can also cause additional inconvenience and risks for the patient. Utility Model Content

[0007] To overcome the above-mentioned defects, this utility model provides a multi-threaded dental implant, which solves the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-threaded dental implant, comprising a bottom, a middle part coaxially fixedly connected to the bottom, and an upper part coaxially fixedly connected to the middle part.

[0009] As a further embodiment of this utility model: the bottom side is provided with double threads.

[0010] As a further embodiment of this utility model: the middle part is conical, the smaller end face of the middle part is fixedly connected to the bottom, and the larger end face of the middle part is fixedly connected to the upper part.

[0011] As a further embodiment of this utility model: a tapered thread is provided on the middle side, the taper of the tapered thread is the same as the taper of the middle part, and the direction of rotation of the tapered thread is the same as the direction of rotation of the double thread.

[0012] As a further embodiment of this utility model: the upper side surface is provided with a reverse thread.

[0013] As a further aspect of this utility model: the direction of rotation of the reverse thread is opposite to that of the double thread.

[0014] As a further embodiment of this utility model: a guide groove is provided on the side wall of the middle part, and a guide groove is also provided on the side wall of the upper part.

[0015] As a further embodiment of this utility model: the upper part is fixedly connected to a top.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model is provided with a central tapered thread area. Through the double thread at the bottom, the dental implant can quickly enter the pre-implantation hole and form a threaded connection with the hole. This provides axial force to the central tapered thread section, thereby compressing the bone around the hole. After compression, the stress on the surrounding bone increases, making the dental implant connection more stable.

[0018] 2. The design of this utility model adopts a unique reverse thread structure in the upper part. This design, combined with the threads in the bottom and middle parts, forms a mechanical self-locking mechanism. This mechanism can effectively enhance the connection stability between the implant and the root bone layer, ensuring the firmness of the implant, thereby providing more reliable support for tooth restoration and reconstruction.

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution:

[0026] A multi-threaded dental implant includes a base 1, a middle section 2 coaxially fixed to the base 1, and an upper section 3 coaxially fixed to the middle section 2. During the implantation process, the positional relationship of the three main parts of the implant must first be determined. The base 1 is located at the bottom, followed by the middle section 2, which is positioned above the base 1, and the upper section 3 is positioned above the middle section 2. In the actual implantation process, the dentist first needs to perform precise drilling in the alveolar bone region corresponding to the missing tooth. This drilling creates a suitable space for the implant placement. The dentist then precisely aligns the implant with the prepared hole. Next, like tightening a screw, the dentist screws the implant into the hole in the alveolar bone, ensuring the implant is securely fixed in the correct position.

[0027] The bottom 1 has a double thread 4 on its side. During dental implant surgery, the bottom 1 is the first part guided into the cavity. The double thread 4 on the bottom 1 is a clever design because it is based on two centrally symmetrical thread structures. This structure makes it easier and smoother for the implant to enter the pre-drilled cavity in the alveolar bone. When the double thread 4 on the bottom 1 begins to screw in, the force on the implant during the screwing process is also symmetrically distributed due to the central symmetry of the two threads. This symmetrical force distribution is crucial for the implant because it ensures the implant remains stable during placement, avoids tilting caused by uneven force, and thus improves the success rate of the implant surgery and the long-term stability of the implant.

[0028] The middle section 2 is conical. Its smaller end face is fixedly connected to the bottom section 1, and its larger end face is fixedly connected to the upper section 3. During dental implant surgery, the middle section 2 gradually penetrates into the pre-drilled hole in the alveolar bone as the bottom section 1 rotates. Because of its conical design, the middle section 2 exerts pressure on the surrounding alveolar bone during insertion into the hole. This compression causes concentrated stress in the bone around the hole. This stress concentration helps increase bone strength, thereby enhancing the stability of the implant and ensuring it is firmly fixed within the alveolar bone.

[0029] A tapered thread 5 is provided on the side of the middle section 2. The taper of the tapered thread 5 is the same as that of the middle section 2, and the direction of rotation of the tapered thread 5 is the same as that of the double thread 4. Through the carefully designed tapered thread 5, the insertion process of the implant can be effectively facilitated, allowing it to enter the hole more smoothly. This special thread design not only helps to form a tighter connection, but also has its unique structural advantages. Specifically, the pitch and thread depth of the tapered thread 5 have been specially adjusted to be smaller than the corresponding parameters of the double thread 4. This means that the thread of the tapered thread 5 is finer and denser. This design allows the tapered thread 5 to generate sufficient axial force while utilizing the thread marks already formed by the double thread 4, thereby ensuring the stability and reliability of the implant.

[0030] The upper part 3 has a reverse thread 6 on its side. The direction of the reverse thread 6 is opposite to that of the double thread 4. When the upper part 3 enters the hole opened in the alveolar bone, since its direction of rotation is opposite to that of the double thread 4 and the tapered thread 5, an axial force is generated. This axial force is opposite to the axial force generated by the bottom part 1 and the middle part 2, which makes the implant self-locking in the hole, thereby making the connection between the implant and the alveolar bone tighter.

[0031] A guide groove 7 is provided on the side wall of the middle part 2, and a guide groove 7 is also provided on the side wall of the upper part 3. Inside the hole, the uncomfortable blood and bone fragments and other impurities can be smoothly discharged from the body through the carefully designed guide groove 7.

[0032] The upper part 3 is fixedly connected to the top 8. The 8th force point at the top is ingeniously designed. It not only makes it easy for doctors to hold the crown during the restoration, but also plays a crucial role in the subsequent fixation process, ensuring the stability and durability of the crown.

[0033] The working principle of this utility model is as follows:

[0034] During dental implant surgery, the first step is to determine the positional relationship of the three main parts of the implant. The base (part 1) is located at the bottom, followed by the middle (part 2), which is positioned above the base (part 1), and the upper (part 3), which is positioned above the middle (part 2). In the actual implantation process, the dentist first needs to precisely drill a hole in the alveolar bone corresponding to the missing tooth. This drilling creates a suitable space for the implant placement. The dentist then precisely aligns the implant with the prepared hole. Next, like tightening a screw, the dentist will screw the implant into the hole in the alveolar bone, ensuring the implant is securely fixed in the correct position.

[0035] During dental implant surgery, the bottom section (section 1) is the first part guided into the cavity. This section features a double-threaded section (section 4), a clever design based on two centrally symmetrical threads. This structure allows the implant to enter the pre-drilled cavity in the alveolar bone more smoothly and easily. As the double-threaded section (section 4) begins to screw in, the forces acting on the implant are symmetrically distributed due to the central symmetry of the two threads. This symmetrical force distribution is crucial for the implant, ensuring its stability during placement and preventing tilting caused by uneven force, thus improving the success rate of the surgery and the long-term stability of the implant.

[0036] During dental implant surgery, the middle section 2 gradually penetrates into the pre-drilled hole in the alveolar bone as the bottom section 1 rotates in. Because the middle section 2 has a tapered design, it applies pressure to the surrounding alveolar bone during insertion, causing concentrated stress in the bone around the hole. This stress concentration helps increase bone strength, thereby enhancing implant stability and ensuring the implant is firmly fixed within the alveolar bone.

[0037] The carefully designed tapered thread 5 effectively facilitates implant insertion, allowing it to enter the cavity more smoothly. This special thread design not only helps form a tighter connection but also offers unique structural advantages. Specifically, the pitch and depth of tapered thread 5 have been specially adjusted to be smaller than the corresponding parameters of double thread 4. This means that the tapered thread 5 has a finer and denser thread. This design allows tapered thread 5 to generate sufficient axial force while utilizing the existing thread marks of double thread 4, thereby ensuring the stability and reliability of the implant.

[0038] Finally, when the upper part 3 enters the hole made in the alveolar bone, because its rotation direction is opposite to that of the double thread 4 and the tapered thread 5, an axial force is generated. This axial force is opposite to the axial force generated by the bottom part 1 and the middle part 2, which makes the implant self-locking in the hole, thus making the connection between the implant and the alveolar bone tighter. Inside the hole, the uncomfortable blood and bone debris can be smoothly drained through the carefully designed guide groove 7. The eighth fulcrum at the top is very cleverly designed. It not only makes it easy for the doctor to hold the crown during the crown restoration, but also plays a crucial role in the subsequent fixation process, ensuring the stability and durability of the crown.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
