Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to a short implant with an abutment. Background Technique

[0002] When the vertical bone mass of the maxillary or mandibular alveolar ridge is insufficient, bone augmentation surgery is usually required first to prepare sufficient bone mass for implant placement before implanting. After bone augmentation surgery, a bone recovery period of more than half a year is required before implanting. On the one hand, it prolongs the time of tooth loss for patients. On the other hand, since bone augmentation surgery requires the use of bone powder, bone membrane, titanium mesh, etc., it increases the economic burden on patients. In addition to the bone augmentation method, due to the short length of the short implant, it can be used even under the condition of insufficient vertical bone mass, thus reducing the tooth loss time and the economic burden on patients. However, due to the structural design of traditional short implants, the shortest length is generally 7 mm, which limits its use under some conditions. Content of the Utility Model

[0003] The purpose of the utility model is to provide a short implant with an abutment to solve the problems raised in the above background technique.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A short implant with an abutment, the short implant includes a retention device and an implant, and the retention device and the implant are threadedly connected;

[0006] The retention device includes a lower connecting part, a step, and an upper connecting part. The upper connecting part is fixedly connected to the step, the step is fixedly connected to the lower connecting part, and the lower connecting part is threadedly connected to the implant.

[0007] A stable dental implant system is formed through the cooperation of the retention device and the implant. The implant provides a stable and supporting effect. The retention device is composed of a lower connecting part, a step, and an upper connecting part. The implant is connected through the lower connecting part, and the upper connecting part is connected through the step. The upper connecting part can install a dental crown. Compared with traditional short implants, the retention device has fewer parts and a shorter length, and the implant is also shorter, further reducing the length of the implant and expanding the use range of short implants in the case of insufficient vertical bone mass.

[0008] Furthermore, the lower connecting part is provided with a first tapered surface, and the lowermost end of the vertical cross-section of the first tapered surface is inclined in the center.

[0009] The lower connecting part of the retention device only has the part with the first tapered surface, canceling the threaded post part below the first tapered surface compared with traditional short implants, making the short implant shorter.

[0010] Furthermore, a tapered groove is provided inside the implant.

[0011] The lower connecting part only has the part with the first conical surface, and the implant only has a conical groove. Compared with the traditional short implant, the threaded groove part below the conical groove is cancelled, making the short implant shorter in length.

[0013] The conical groove and the first conical surface are threadedly connected, enabling the connection between the implant and the retention device. Due to the use of conical threads, the lower connecting part of the retention device can better fit the conical groove of the implant, resulting in better tightness between the implant and the retention device. Under the chewing force of the dental crown, the phenomenon of slippage of the retention device 1 can be effectively avoided, and better stability can be maintained in a high-pressure environment.

[0014] Furthermore, the implant is provided with a cylindrical groove, and the cylindrical groove is located below the conical groove.

[0015] During the long-term use of the short implant, due to the chewing force, the retention device may move downward. By providing a cylindrical groove in the implant, the lower connecting part will not be damaged due to long-term use, and the self-tightening of the retention device and the implant can be achieved through the downward movement.

[0016] Furthermore, the step is provided with a second conical surface.

[0017] Through the second conical surface provided on the step, the connection between the retention device and the implant is made tighter, the gap at the connection is reduced, the retention device is not easily loosened, thereby improving the stability and durability of the short implant. At the same time, the closure of the interface between the implant and the retention device is achieved, and the second conical surface is also beneficial for preventing the entry of food residues and bacteria, reducing the risk of infection.

[0018] Furthermore, the cross-section of the lower end of the upper connecting part is a dodecagon, which consists of six large faces and six small faces, and the upper end of the upper connecting part is a frustum of a cone.

[0019] Through the shape setting of the upper connecting part, it is beneficial for the rapid and accurate positioning during the installation of the dental crown, and the dental crown can be quickly installed easily. When under the chewing force of the dental crown, the lateral force received by the polygon at the lower end of the upper connecting part is better dispersed, and the anti-rotation ability is stronger.

Under the chewing force of the dental crown, the phenomenon of slippage of the retention device can be effectively avoided, and better stability can be maintained in a high-pressure environment. The upper connecting part can be installed with a dental crown. Compared with traditional short implants, the retention device has fewer parts and a shorter length, and the implant is also shorter, further reducing the length of the implant and expanding the application range of short implants in cases of insufficient vertical bone mass. Through the second tapered surface provided on the step, the connection between the retention device and the implant is made closer, reducing the gap at the connection and making the retention device not easily loose, thereby improving the stability and durability of the short implant, and at the same time achieving the sealing of the interface between the implant and the retention device.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides the following technical solutions:

[0029] Such asFigures 1 to 2 As shown, a short implant with an abutment, the short implant includes a retention device 1 and an implant 2, and the retention device 1 and the implant 2 are threadedly connected;

[0030] The retention device 1 includes a lower connecting portion 11, a step 12, and an upper connecting portion 13. The upper connecting portion 13 and the step 12 are fixedly connected, the step 12 and the lower connecting portion 11 are fixedly connected, and the lower connecting portion 11 and the implant 2 are threadedly connected.

[0031] A stable dental implant system is formed by the cooperation of the retention device 1 and the implant 2. The implant 2 provides a stable and supporting function. The retention device 1 is composed of a lower connecting portion 11, a step 12, and an upper connecting portion 13. The implant 2 is connected through the lower connecting portion 11, and the upper connecting portion 13 is connected through the step 12. The upper connecting portion 13 can be installed with a dental crown. Compared with traditional short implants, the retention device 1 has fewer parts and a shorter length, and the implant 2 is also shorter, further reducing the length of the implant and expanding the application range of the short implant 2 in the case of insufficient vertical bone mass.

[0032] As Figure 2 shown, the lower connecting portion 11 is provided with a first tapered surface 111, and the lowermost end of the vertical cross-section of the first tapered surface 111 is inclined in the center.

[0033] The lower connecting portion 11 of the retention device 1 only has the part with the first tapered surface 111, and the threaded post part below the first tapered surface 111 is cancelled compared with the traditional short implant, making the short implant shorter.

[0034] As Figure 3 shown, a tapered groove 21 is provided inside the implant 2.

[0035] The lower connecting portion 11 only has the part with the first tapered surface 111, and the implant 2 only has the tapered groove 21. The threaded groove part below the tapered groove 21 is cancelled compared with the traditional short implant, making the short implant shorter.

[0036] As Figures 1 to 3 shown, the tapered groove 21 is provided with internal threads, the tapered groove 21 and the first tapered surface 111 have the same taper, the first tapered surface 111 is provided with external threads, the internal threads and the external threads are engaged, and the tapered groove 21 and the first tapered surface 111 are threadedly connected.

[0037] The tapered groove 21 and the first tapered surface 111 are connected by threads, so that the implant 2 and the retention device 1 are connected. Due to the use of tapered threads, the lower connecting portion 11 of the retention device 1 can better fit the tapered groove 21 of the implant 2, making the implant 2 and the retention device 1 have better tightness. Under the chewing force of the dental crown, the phenomenon of slippage of the retention device 1 can be effectively avoided, and better stability can be maintained in a high-pressure environment.

[0038] As Figure 3 shown, the implant 2 is provided with a cylindrical groove, and the cylindrical groove is located below the conical groove 21.

[0039] Under long-term use of the short implant, due to the action of the chewing force, the retention device 1 may move downward. By providing the cylindrical groove in the implant 2, the lower connecting portion 11 will not be damaged due to long-term use. The downward movement generated can achieve self-tightening of the retention device 1 and the implant 2.

[0040] As Figure 2 shown, the step 12 is provided with a second conical surface 121.

[0041] By providing the second conical surface on the step 12, the connection between the retention device 1 and the implant 2 is made closer, the gap at the connection is reduced, the retention device 1 is not easily loosened, thereby improving the stability and durability of the short implant. At the same time, the closure of the interface between the implant 2 and the retention device 1 is achieved. Through the second conical surface 121, it is also beneficial to prevent the entry of food residues and bacteria, reducing the risk of infection.

[0042] As Figure 4 shown, the lower end cross-section of the upper connecting portion 13 is a dodecagon, which consists of six large faces and six small faces, and the upper end of the upper connecting portion 13 is a frustum of a cone.

[0043] Through the shape setting of the upper connecting portion 13, it is beneficial for the quick and accurate positioning during the installation of the dental crown. It is easy to operate and can achieve the quick installation of the dental crown. When subjected to the chewing force of the dental crown, the lateral force received by the polygon in the lower half of the upper connecting portion 13 is better dispersed, and the anti-rotation ability is stronger.

[0044] Working principle of the present utility model: The implant 2 is installed on the alveolar bone. The external thread of the implant 2 can fit more closely with the alveolar bone. The implant 2 is threadedly connected to the retention device 1. Due to the use of tapered threads, the implant 2 and the retention device 1 have better tightness. Under the action of the chewing force of the dental crown, the phenomenon of slippage of the retention device 1 can be effectively avoided, and the stability is better. After long-term use, due to the action of the chewing force, the retention device 1 may move downward. Through the cylindrical groove provided in the implant 2, the downward movement can achieve self-tightening of the retention device 1 and the implant 2. Through the second tapered surface 121 provided on the step 12, the connection between the retention device 1 and the implant 2 is made closer, reducing the gap at the connection, making the retention device 1 not easily loose, thereby improving the stability and durability of the short implant. At the same time, the interface between the implant 2 and the retention device 1 is closed, which is also beneficial to preventing the entry of food residues and bacteria, reducing the risk of infection. Through the shape setting of the upper connecting portion 13, rapid and accurate positioning can be achieved when installing the dental crown, realizing the rapid installation of the dental crown. When under the action of the chewing force of the dental crown, the lateral force received by the polygon in the lower half of the upper connecting portion 13 is better dispersed, and the anti-rotation ability is stronger. A stable dental implant system is formed by the implant 2 and the retention device 1.
