[0002] With the continuous improvement of people's living standards and medical standards, dental services such as tooth replacement, filling, and teeth cleaning are becoming increasingly popular. Dental restoration, as a dental service, refers to the restoration of the inherent form and function of tooth tissue through a certain procedure using specific materials based on the removal of damaged or severely weakened tooth tissue.

[0003] The installation between the dentures and adjacent teeth currently on the market is too simple. Some are only fixed by simple clamping and glue, which results in the overall connection being not stable enough and is prone to loosening after long-term use. Therefore, the utility model provides an embedded combined fixed dental bridge device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the installation between the dentures and the positioning teeth currently on the market is too simple, and some are only fixed by simple clamping and glue, which leads to the overall connection being not stable enough and easily loosening after long-term use.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] In the utility model, by aligning the limiting convex rod with the slide groove and then pushing the crown body to move downward so that the positioning column is inserted into the positioning hole, the stability between the crown body and the denture seat can be increased. When the lower end of the limiting convex rod contacts the lower surface of the inner wall of the slide groove, the slider is pushed to move by the protrusion of the limiting convex rod. The slide rail and the slide bar at the lower end of the slider can prevent the position of the slide rail from shifting. When one end of the slider slides into the inner wall of the slot, the positioning tooth and the denture seat can be connected and limited, and then the hexagon socket bolt is rotated to fix the crown body and the denture seat. The positioning tooth is then fixed to the polished natural tooth through an adhesive and a fixing groove, avoiding the disadvantage of fixing by simple clamping and glue, which leads to the overall connectivity being not stable enough and easily loosening after long-term use.

[0017] Reference Figure 1-4As shown, the utility model provides a technical solution: an embedded combined fixed dental bridge device, including a denture seat 1, a docking groove 3 is provided on the surface of the denture seat 1, a docking block 4 is slidably connected to the inner wall of the docking groove 3, and the upper end of the docking block 4 is fixedly connected to a crown body 2, a through hole 8 is provided on the upper surface of the crown body 2, and a hexagon socket bolt 9 is slidably connected to the inner wall of the through hole 8, a threaded hole 7 is provided on the inner wall of the docking groove 3, and the threaded hole 7 is threadedly connected to the hexagon socket bolt 9, two slide grooves 10 are provided on the surface of the docking groove 3, the inner walls of the two slide grooves 10 are both slidably connected to a limiting convex rod 11, and the upper end of the limiting convex rod 11 is fixedly connected to the surface of the docking block 4, a connecting component is provided at the lower end of the slide groove 10, and the connecting component A positioning tooth 15 is provided at one end of the component. When the denture seat 1 needs to be fixed with the positioning teeth 15 on both sides, first align the limiting convex rod 11 with the slide groove 10, and then push the crown body 2 to move downward. When the lower end of the limiting convex rod 11 contacts the lower surface of the inner wall of the slide groove 10, the convexity of the limiting convex rod 11 pushes the connecting component to move, so that the connecting component limits the connection between the positioning tooth 15 and the denture seat 1, and then align the hexagon socket bolt 9 with the through hole 8 and insert it into the threaded hole 7, and then rotate the hexagon socket bolt 9 to fix the crown body 2 and the denture seat 1, avoiding the fixation by simple clamping and glue, which leads to the overall connectivity being not stable enough and easily loosening after long-term use.

[0018] Reference Figure 1 and Figure 4 As shown, in this embodiment: the connecting component includes a slide rail 13, the slide rail 13 is provided with a lower surface of the inner wall of the slide groove 10, and the inner wall of the slide rail 13 is slidably connected with a slide bar 14, and the upper end of the slide bar 14 is fixedly connected with the slider 12. When the limiting protrusion 11 pushes the slider 12 to slide, the slide rail 13 and the slide bar 14 can prevent the position of the slide rail 13 from shifting, and play a guiding role. The side wall of the positioning tooth 15 is provided with a slot 16, and the inner wall of the slot 16 is slidably connected to the surface of the slider 12. By sliding one end of the slider 12 into the slot 16, the connection between the denture seat 1 and the positioning tooth 15 can be limited by the slider 12.

[0019] Reference Figure 2 and Figure 3 As shown, specifically, two positioning holes 5 are provided on the surface of the docking groove 3, and the inner walls of the two positioning holes 5 are slidably connected with positioning columns 6, and the upper ends of the positioning columns 6 are fixedly connected to the surface of the docking block 4. By inserting the positioning columns 6 into the positioning holes 5, the docking position of the crown body 2 can be prevented from shifting. By enhancing the stability with the denture seat 1, a fixing groove 17 is provided at the lower end of the positioning tooth 15, and the positioning tooth 15 fixes the fixing groove 17 to the polished natural tooth through an adhesive.

[0020] Working principle: when it is necessary to fix the denture seat 1 with the positioning teeth 15 on both sides, first align the limiting convex rod 11 with the slide groove 10, and then push the crown body 2 to move downward. By inserting the positioning column 6 into the positioning hole 5, the docking position of the crown body 2 can be prevented from being offset, thereby enhancing the stability between it and the denture seat 1. When the lower end of the limiting convex rod 11 contacts the lower surface of the inner wall of the slide groove 10, the convexity of the limiting convex rod 11 pushes the slider 12 to move, and the slide rail 13 and the slide bar 14 at the lower end of the slider 12 can prevent the position of the slide rail 13 from being offset. The offset plays a guiding role. When one end of the slider 12 slides into the inner wall of the slot 16, the positioning tooth 15 and the denture seat 1 can be connected and limited, and then the hexagon socket bolt 9 is aligned with the through hole 8 and inserted into the threaded hole 7, and then the hexagon socket bolt 9 is rotated to fix the crown body 2 and the denture seat 1, and then the positioning tooth 15 is fixed to the polished natural tooth through the adhesive and the fixing groove 17, avoiding the fixation by simple clamping and glue, which leads to the overall connectivity being not stable enough and it is easy to loosen under long-term use.
