Abstract
Description
Technical Field
[0001] The invention relates to a dental implant detection device, in particular to a dental implant fatigue test loading component. Background Art
[0002] Dental implants are surgically implanted into the upper and lower jaws of the human body where the teeth are missing. After the wound heals, the abutment and restoration are installed on the upper part. After installation, they will be repeatedly loaded under the action of chewing force. After long-term use, there may be a risk of fracture due to fatigue stress, which will affect the experience of using dental implants. Therefore, it is necessary to conduct dynamic fatigue tests on dental implants in strict accordance with national standards to detect the maximum stress that dental implants can withstand.
[0003] The loading cap of the dental implant is set as a curved surface, so the loading components commonly used at present mostly use point contact to transfer dynamic loads to the dental implant. The loading cap of the dental implant will be offset after being compressed, and the loading component cannot move with the movement of the loading cap, resulting in the load not being accurately applied to the center point of the loading cap during the test, and errors in the test results. The loading component uses a universal joint to achieve no lateral constraints. The universal joint consists of a pair of hinges, which allow an angle between the two axes of the pair of hinges. The angle changes and the joint can still rotate normally. Therefore, the use of a universal joint will also cause additional dynamic loads, which will cause the universal joint to be easily damaged and the test to be unstable, affecting the test results. Summary of the invention

[0037] Reference below Figures 1 to 5 A dental implant fatigue testing loading assembly 100 according to the present invention is described.

[0039] A first groove 111 and a first through hole 112 are provided on the limiting device 110, and the first through hole 112 is connected to the first groove 111. The limiting device 110 also includes a plurality of ball plunger assemblies 113, and the ball plunger assemblies 113 extend from the side of the limiting device 110 into the first groove 111.

[0040] Specifically, the connection block 120 is supported in the first groove 111 of the limiting device 110, the loading component 130 is connected to the connection block 120, and the loading component 130 passes through the first through hole 112, and the connection block 120 can drive the loading component 130 to move. There is a gap between the connection block 120 and the limiting device 110, and there is also a gap between the loading component 130 and the limiting device 110, so that when the connection block 120 and the limiting device 110 slide relative to each other, the connection block 120 can drive the loading component 130 to move in the horizontal direction, so that during the loading process, after the loading cap is compressed and displaced, the loading component 130 can move in the horizontal direction with the movement of the loading cap, ensuring that the load acts accurately on the center point of the loading cap. At the same time, by providing multiple ball head plunger assemblies 113, the ball head plunger assemblies 113 are extended into the first groove 111 from the side of the limiting device 110, and the ball head is in contact with the connecting block 120. A spring is provided in the ball head plunger assembly 113, and under the action of the spring, the displacement of the connecting block 120 sliding in the horizontal direction each time can be limited.
[0041] In some embodiments of the present invention, the dental implant fatigue test loading assembly 100 further includes a transmission mechanism 150, the transmission mechanism 150 includes a first friction plate 151, a second friction plate 152 and a ball 153, a second groove 141 is provided on the mounting block 140, a third groove is provided on the connecting block 120, the second groove 141 is opposite to the opening of the third groove, the first friction plate 151 is arranged in the second groove 141, the second friction plate 152 is arranged in the third groove, and the ball 153 is arranged between the first friction plate 151 and the second friction plate 152.

Specifically, by arranging the first friction plate 151 in the second groove 141, the second friction plate 152 in the third groove, and the ball 153 between the first friction plate 151 and the second friction plate 152, the first friction plate 151, the second friction plate 152 and the ball 153 cooperate to achieve the function of a bearing, so that the load is transmitted downward through the first friction plate 151, the ball 153 and the second friction plate 152 in sequence, and the friction between the first friction plate 151 and the second friction plate 152 can be reduced by the ball 153, so that the connection block 120 and the mounting block 140 can slide relative to each other. The lower half of the ball 153 is located in the third groove, and the ball 153 covers the entire third groove, so that the ball 153 can roll while the connecting block 120 slides in the horizontal direction; the upper half of the ball 153 is arranged in the second groove 141 of the mounting block 140 to limit the range of movement of the ball 153 in the second groove 141.

Specifically, the pressure head 132 is detachably mounted on the pressure rod 131. When the pressure head 132 is worn during use and affects the test result, the accuracy of the test can be ensured by directly removing and replacing the pressure head 132 without disassembling the entire dental implant fatigue test loading assembly 100, thereby improving the accuracy of the test result and ensuring the efficiency of the test.
[0043] In some embodiments of the present invention, the first groove 111 cooperates with the first through hole 112 to form a stepped hole, the outer diameter of the connecting block 120 is smaller than the diameter of the first groove 111 and larger than the diameter of the first through hole 112, and the diameter of the pressing rod 131 is smaller than the diameter of the first through hole 112. For example, Figure 3 and Figure 4As shown, the first groove 111 cooperates with the first through hole 112 to form a stepped hole. Specifically, the cross-sections of the first groove 111 and the first through hole 112 are both set to be circular, and the first groove 111 cooperates with the first through hole 112 to form a stepped hole, that is, the diameter of the first groove 111 is greater than the diameter of the first through hole 112, and the outer diameter of the cylindrical connecting block 120 is smaller than the diameter of the first groove 111 and greater than the diameter of the first through hole 112, so that when the connecting block 120 is supported in the first groove 111, there is a gap between the two, which facilitates the relative sliding between the connecting block 120 and the first groove 111, and the pressure rod 131 installed on the connecting block 120 can also slide with the sliding of the connecting block 120. It can be understood that the cross-sections of the first groove 111 and the first through hole 112 can also be set to a square or elliptical shape.

Specifically, the connection block 120 and the loading component 130 are both set to be cylindrical, and the diameter of the pressure rod 131 of the loading component 130 is smaller than the diameter of the first through hole 112, so that the connection block 120 can drive the loading component 130 and the limit device 110 to slide relative to each other. After the connection block 120 and the loading component 130 are connected, they are T-shaped, and the step hole formed by the first groove 111 and the first through hole 112 cooperates with each other.

Specifically, the flange 142 is arranged on the side of the mounting block 140 away from the limiting device 110, and the fifth threaded holes 143 are provided on the flange 142. The mounting block 140 is used to be connected with the fatigue testing machine, and the mounting block 140 is installed on the fatigue testing machine by screwing the bolts into the fifth threaded holes 143 and the threaded holes on the fatigue testing machine, so that the load on the fatigue testing machine is transferred to the dental implant fatigue testing loading assembly 100.
[0049] In some embodiments of the present invention, four ball head plunger assemblies 113 are provided, and the ball head plunger assemblies 113 are distributed in a cross shape. Specifically, a spring is provided in the ball head plunger assembly 113, and the displacement of the loading component 130 each time can be limited by the spring; by providing four ball head plunger assemblies 113 and distributing the four ball head plunger assemblies in a cross shape, the loading component 130 can be restricted from four directions respectively, so as to avoid a large movement of the loading component 130, which affects the detection result, and ensures the stability during the detection process. It can be understood that different numbers of ball head plunger assemblies 113 can be provided according to actual detection requirements, and the use of four ball head plunger assemblies 113 in this embodiment is not a specific limitation of the present invention.
[0050] Reference below Figures 1 to 5 The dental implant fatigue test loading assembly 100 according to the present invention is described in detail with reference to a specific embodiment. It should be understood that the following description is only an exemplary illustration and is not a specific limitation to the present invention.
[0051] like Figures 1 to 5 As shown, the mounting block 140 is mounted on the limiting device 110, a first groove 111 is provided on one side of the limiting device 110 close to the mounting block 140, and a first through hole 112 connected to the first groove 111 is provided on the limiting device 110, the connecting block 120 is limited in the circular first groove 111, the pressure rod 131 passes through the first through hole 112, the pressure head 132 is mounted on the pressure rod 131, the pressure rod 131 is mounted on the connecting block 120, and the loading component 130 and the limiting device 110 can slide relative to each other.

[0052] Specifically, a second groove 141 with a circular cross-section is provided on the mounting block 140, and a third groove with a circular cross-section is provided on the connecting block 120. The second groove 141 is opposite to the opening of the third groove. The first friction block is arranged in the second groove 141, and the second friction block is arranged in the circular third groove of the connecting block 120. The diameter of the second groove 141 is larger than the diameter of the third groove. A ball 153 is installed between the first friction block and the second friction block, and the lower half of the ball 153 is covered with the third groove, so that the ball 153 and the connecting block 120 can move synchronously in the horizontal direction. The upper half of the ball 153 is located in the second groove 141 to limit the rolling of the ball 153 in the second groove 141. The connecting block 120 is configured to be cylindrical, and the outer diameter of the connecting block 120 is smaller than the diameter of the first groove 111 and larger than the diameter of the first through hole 112, so that the connecting block 120 is supported in the first groove 111, and the diameter of the pressure rod 131 is smaller than the diameter of the first through hole 112, so that when the pressure rod 131 is installed on the connecting block 120, it can also slide with the sliding of the connecting block 120 in the horizontal direction, so that the loading component 130 has a certain degree of freedom in the horizontal direction. The limiting device 110 is provided with a first threaded hole, and the mounting block 140 is provided with a second threaded hole. The first threaded hole and the second threaded hole are opposite to each other. By screwing the bolt into the first threaded hole and the second threaded hole, the limiting device 110 and the mounting block 140 are connected.

In the process of transferring the load, after the loading cap is compressed and displaced, the loading component 130 can move in the horizontal direction with the movement of the loading cap, so that the load acts accurately on the center point of the loading cap in a point contact manner, and no displacement occurs. Since the limiting device 110 also includes four ball head plunger assemblies 113 distributed in a cross shape, the displacement of the loading component 130 in the horizontal direction can be limited from four directions, and the stability during the detection process can be ensured. The pressure head 132 in the loading component 130 is detachably mounted on the pressure rod 131. When the pressure head 132 is damaged during the detection process, it can be directly removed and replaced without reinstalling the dental implant fatigue test loading assembly 100, thereby improving the detection efficiency.
