Description

Technical Field

[0001] This utility model relates to anchorage nails, specifically an anchorage nail designed to prevent loosening. Background Technology

[0002] With the widespread use and popularity of dental implants, the probability of anchorage screw loosening and slippage in clinical practice is less than 5%. As the use of anchorage screws increases, a better surface coating process is needed to enhance the tight integration between the screw and alveolar bone, enabling the screw surface to form biocompatibility with the alveolar bone and, over time, establish a stable implant relationship. However, due to the complexity and uncertainty of the coating process during production, some anchorage screws still loosen and fall out during clinical implant procedures, often accompanied by gingival recession. Therefore, a new anchorage screw design to prevent loosening is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a support nail that prevents loosening in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a support nail for preventing loosening, comprising a support nail body; characterized in that the support nail body is provided with threads, the threads comprising a front thread with gradually increasing thread height, a middle thread with uniform thread height, and a tail thread with gradually increasing thread height.

[0005] More preferably, the front thread of the anchor pin is tapered, and the front thread gradually increases in height along the tapered section until it matches the height of the middle thread.

[0006] Further preferably, it also includes a cap body disposed on the anchoring nail body, a neck disposed at the upper end of the cap body, and a top end disposed at the upper end of the neck.

[0007] The beneficial effects of this utility model are as follows: By gradually increasing the height of the thread at the tail end of the anchorage screw, the anchorage screw is implanted into the alveolar bone according to the implantation thread direction during clinical use. The gradually increasing thread height at the tail end creates a tighter mechanical fixation force with the alveolar bone. Even if external forces are generated during long-term use, rotation cannot occur, and thus loosening or slippage will not easily occur, ensuring that the anchorage screw has a long-term effective and stable use effect.

[0008] Furthermore, this invention does not require changes to doctors' usage habits, does not require additional disinfection procedures, and does not require changes to the production process. In actual production and use, it is simple, convenient, and practical, greatly reducing the probability of loosening and slippage of the anchorage screws and ensuring the long-term stable use of intraoral implants for patients.

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the anti-loosening anchor nail of this utility model.

[0013] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] See Figures 1-2 As shown, a support nail for preventing loosening includes a support nail body 1; characterized by a thread provided on the support nail body 1, the thread including a front thread 2 with gradually increasing thread height, a middle thread 3 with uniform thread height, and a tail thread 4 with gradually increasing thread height.

[0016] This invention involves gradually increasing the height of the thread 4 at the tail end of the anchorage screw. During clinical use, the anchorage screw is implanted into the alveolar bone according to the implantation thread direction. The gradually increasing thread structure of the tail end thread 4 creates a tighter mechanical retention force with the alveolar bone. During long-term use, even if external forces are generated, rotation cannot occur, and thus loosening or slippage will not easily occur, ensuring that the anchorage screw has a long-term effective and stable use effect.

[0017] Furthermore, this invention does not require changes to doctors' usage habits, does not require additional disinfection procedures, and does not require changes to the production process. In actual production and use, it is simple, convenient, and practical, greatly reducing the probability of loosening and slippage of the anchorage screws and ensuring the long-term stable use of intraoral implants for patients.

[0018] The anchoring nail achieves a stable mechanical retention effect through the combination of the standard thread structure of the front thread 2 and the middle thread 3 with the gradually increasing tail thread 4.

[0019] The design of the tail section with an increased thread height 4 increases the contact area and depth with the alveolar bone on the basis of the original thread structure, enabling it to fuse more closely and effectively with the bone tissue.

[0020] In one embodiment, the front thread 2 of the anchorage screw is tapered, and the front thread 2 gradually increases in height along the tapered section until it is consistent with the height of the middle thread 3. The tapered design of the front end of the anchorage screw is to enable the anchorage screw to be driven into the alveolar bone.

[0021] In one embodiment, it further includes a cap 5 disposed on the anchoring nail body 1, a neck 6 disposed on the upper end of the cap 5, and a top end 7 disposed on the upper end of the neck 6.

[0022] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
