Description

Technical Field

[0001] This utility model relates to the field of dental restoration abutment technology, and in particular to a multi-stage composite abutment for dental restoration. Background Technology

[0002] With the development of dental implant technology, the research focus has gradually shifted from meeting functional requirements to shortening treatment time, reducing the number of surgeries, restoring aesthetics and occlusal function as quickly as possible, reducing bone resorption, and maintaining long-term stability. Currently, most implants require two or more surgeries, and the superstructure crown can only be restored after the second surgery.

[0003] While existing one-piece implants can reduce the number of surgeries, each patient's tooth shape is different. After the implant is placed in the alveolar bone, the opposing tooth may come into contact with the upper part of the implant, causing pressure on the implant. This can prevent the implant from integrating well with the alveolar bone, prolonging the recovery period. In addition, the restoration may not be flush with the tooth after implantation, affecting daily use. Utility Model Content

[0004] The purpose of this invention is to provide a multi-level composite abutment for dental restoration, which can solve at least one of the above-mentioned technical problems. The technical solution of this invention is as follows:

[0005] A multi-stage composite abutment for dental restoration includes: a fixed body, a slot provided in the fixed body, a movable body provided in the slot, a positioning part provided at the upper end of the movable body, a restoration body fixedly provided on the positioning part, and a multi-stage adjustment part provided in the slot and on the movable body for multi-stage adjustment of the height of the movable body.

[0006] Furthermore, the movable body includes a guide post fixed in the middle of the slot, a movable sleeve provided on the guide post and disposed in the slot, a plug-in block symmetrically fixed at the lower end of the movable sleeve, and guide grooves symmetrically provided in the slot, with the plug-in block disposed in the guide groove.

[0007] Furthermore, the positioning part includes a fixing seat fixed to the upper end of the movable sleeve, a trapezoidal groove is provided on the fixing seat, a trapezoidal block is inserted into the trapezoidal groove, a conical connecting block is fixed on the trapezoidal block, and the repair body is fixed on the conical connecting block.

[0008] Furthermore, the multi-stage adjustment section includes multiple annular grooves spaced apart within the slot, and each of the plug-in blocks is rotatably inserted into the annular groove, wherein the annular groove and the guide groove are connected.

[0009] Preferably, the fixing body is provided with a fixing thread, and the upper end of the fixing body is provided with a rotating cap.

[0010] In summary, the advantages of this utility model over the prior art are:

[0011] This invention provides a multi-stage composite abutment for dental restoration. In use, the fixation body is driven into the area to be restored through the fixing thread, and then the movable body is moved to the required height along the slot. At this time, the user rotates the movable body and limits the height of the movable body through the multi-stage adjustment part. Then, the user glues and fixes the restoration body and the positioning part together, and at the same time glues and fixes the positioning part above the movable body. Compared with the prior art, it can integrate well with the alveolar bone after the implant is inserted into the alveolar bone, and can be flush with the tooth. Attached Figure Description

Rotating cap. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 3 A multi-stage composite abutment for dental restoration is shown, characterized in that it includes: a fixed body 1, a slot 2 provided in the fixed body 1, a movable body 3 provided in the slot 2, a positioning part 4 provided at the upper end of the movable body 3, a restoration body 5 fixedly provided on the positioning part 4, and a multi-stage adjustment part 6 provided in the slot 2 and on the movable body 3, which can adjust the height of the movable body 3 in multiple stages.

[0018] The fixing body 1 is provided with a fixing thread 11, and the upper end of the fixing body 1 is provided with a rotating cap 12.

[0019] The above-described multi-stage composite abutment for dental restoration involves inserting the fixation body 1 into the area to be restored via the fixing thread 11. During insertion, the rotating cap 12 on the fixation body 1 assists in its rotation. Then, the movable body 3 is moved along the slot 2 to the desired height. The user then rotates the movable body 3 and limits its height using the multi-stage adjustment part 6. Finally, the user adhesively fixes the restoration body 5 and the positioning part 4 together, while simultaneously adhesively fixing the positioning part 4 above the movable body 3. Compared to existing technologies, this method allows for better integration with the alveolar bone after implantation, while maintaining a flush position with the tooth.

[0020] like Figure 2 and 3 As shown, in some embodiments of this utility model, the movable body 3 includes a guide post 31 fixed in the middle of the slot 2, a movable sleeve 32 provided on the guide post 31 and disposed in the slot 2, a plug-in block 33 symmetrically fixed at the lower end of the movable sleeve 32, a guide groove 34 symmetrically provided in the slot 2, and the plug-in block 33 disposed in the guide groove 34. When the user pulls the movable sleeve 32, the movable sleeve 32 moves upward along the guide post 31, and at the same time the plug-in block 33 symmetrically fixed at the lower end of the movable sleeve 32 moves along the guide groove 34.

[0021] like Figure 2 and 3 As shown, in some embodiments of this utility model, the positioning part 4 includes a fixing seat 41 fixed to the upper end of the movable sleeve 32. A trapezoidal groove 42 is provided on the fixing seat 41, a trapezoidal block 43 is inserted into the trapezoidal groove 42, and a conical connecting block 44 is fixed on the trapezoidal block 43. The repair body 5 is fixed on the conical connecting block 44. The user first glues the repair body to the conical connecting block 44 with adhesive, and at the same time glues the trapezoidal block 43 into the trapezoidal groove 42 with adhesive, so that the repair body 5 covers the fixing seat 41 fixed to the upper end of the movable sleeve 32.

[0022] like Figure 3 As shown, in some embodiments of this utility model, the multi-level adjustment part 6 includes a plurality of annular grooves 61 spaced apart in the slot 2. Each of the plug-in blocks 33 is rotatably inserted into the annular groove 61. The annular groove 61 and the guide groove 34 are connected. After the user pulls the movable sleeve 32 to a suitable height, the user rotates the movable sleeve 32, causing the plug-in block 33 to rotate. At this time, the plug-in block 33 rotates into the annular groove 61, thereby limiting the height of the movable sleeve 32. After limiting, the user can use adhesive to glue and fix the movable sleeve 32 and the slot 2.

[0023] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
