Description

Technical Field

[0001] This utility model relates to the field of dental medical equipment technology, and in particular to a zirconia personalized abutment. Background Technology

[0002] The standard procedure for dental implant restoration currently involves the dentist first implanting the implant into the patient, then creating a model of the implant restoration and transferring it to the prosthesis fabrication lab. When a patient has special requirements and needs a zirconia abutment, and the implant system includes pre-made standard zirconia abutments, the fabrication staff directly selects the appropriate abutment model based on the implant system used by the dentist, places an order, and once the standard abutment arrives, the fabrication staff needs to perform extensive adjustments and grinding based on each patient's specific situation to make it conform as closely as possible to the patient's tooth shape. The porcelain crown is then fabricated on the adjusted zirconia abutment to complete the final implant restoration.

[0003] For example, in the public announcement (CN220069891U), a zirconia personalized base includes a base body. The top of the base body has a conical hole, and the bottom wall of the conical hole has a connected mounting groove. A matching conical block is inserted into the conical hole, and a limiting post that matches the inside of the mounting groove passes through the inside of the conical block. This application, through the arrangement of springs, limiting blocks, and slots, allows the limiting post to be installed by simply inserting it into the mounting slot after passing through the through hole and the conical block, until the limiting block moves to align with the slot. Then, under the elastic action of the two sets of springs, the limiting blocks on both sides move in opposite directions until they are inserted into the slots on both sides, thus preventing the limiting post from detaching from the mounting slot and achieving the installation and fixation of the limiting post. This eliminates the need to tighten screws, making the installation operation more convenient and faster. In contrast, this application only uses the cooperation of springs and limiting blocks to achieve installation and fixation, without setting a device to limit the springs. This causes the limiting blocks to tilt during the deformation of the springs, thus failing to guarantee the stability of the installation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By placing multiple triangular blocks within the limiting ring, rotating the insert rod and the crown causes the multiple triangular blocks and multiple strip grooves to intersect and be within the limiting ring, so that the lower ends of the multiple triangular blocks cooperate with the limiting ring, thereby limiting the insertion rod and the slot and realizing the rapid installation of the crown. This invention proposes a zirconia personalized abutment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A zirconia personalized abutment includes a base, a slot at the upper end of the base, an insert rod above the base, the insert rod cooperating with the slot, a crown at the upper end of the insert rod, multiple circumferentially arranged strip grooves on the outer wall of the insert rod, a cavity inside the insert rod, a limiting mechanism for limiting the insertion rod in the cavity and the strip grooves, and a mating mechanism cooperating with the limiting mechanism in the slot.

[0007] Preferably, the limiting mechanism includes a through groove formed between the strip groove and the chamber, and a locking block is slidably connected through the through groove.

[0008] Preferably, the mating mechanism includes multiple circumferentially arranged slots formed on the inner wall of the slot, each of the multiple slots mating with a multiple card blocks, and both the multiple slots and card blocks are rectangular.

[0009] Preferably, the inner wall of the slot is provided with a plurality of circumferentially arranged triangular blocks, and the lower end of each of the plurality of blocks is provided with an inclined surface, the inclined surface cooperating with the inclined end of the triangular block, and the plurality of triangular blocks respectively cooperating with a plurality of strip grooves.

[0010] Preferably, the cavity is provided with multiple sets of circumferentially arranged limiting rods, and the outer walls of the multiple sets of limiting rods are slidably connected to a sliding plate. Multiple locking blocks are respectively connected to multiple sliding plates, and the sliding plates are elastically connected to the inner wall of the cavity through multiple springs.

[0011] Preferably, a limiting ring is provided between the multiple strip grooves, and the limiting ring cooperates with multiple triangular blocks.

[0012] The beneficial effects of this utility model are:

[0013] 1. By ensuring that multiple triangular blocks are all within the limiting ring, the insert rod and the crown are rotated, causing the multiple triangular blocks and multiple slots to intersect and be within the limiting ring. This allows the lower ends of the multiple triangular blocks to engage with the limiting ring, thereby limiting the insertion rod and slot and enabling the rapid installation of the crown.

[0014] 2. By having multiple springs bring the slide back to the starting position, the slide brings the locking block back to the starting position, allowing the locking block to be inserted into the slot through the strip groove, thereby fixing the connection between the plug rod and the base and improving the stability of the connection between the two.

[0021] Reference Figure 1-3 A personalized zirconia abutment includes a base 1, a slot 2 at the upper end of the base 1, an insertion rod 5 above the base 1, the insertion rod 5 cooperating with the slot 2, a crown 6 at the upper end of the insertion rod 5, a plurality of circumferentially arranged strip grooves 7 on the outer wall of the insertion rod 5, a chamber 12 inside the insertion rod 5, and a limiting mechanism for limiting the insertion rod 5 within the chamber 12 and the strip grooves 7. The limiting mechanism includes a through groove 11 between the strip grooves 7 and the chamber 12, and a locking block 9 slidingly connected through the through groove 11.

[0022] The slot 2 is equipped with a cooperating mechanism that works with the limiting mechanism. The cooperating mechanism includes multiple circumferentially arranged slots 4 on the inner wall of the slot 2. The multiple slots 4 respectively cooperate with multiple card blocks 9. Both the multiple slots 4 and the card blocks 9 are rectangular.

[0023] The inner wall of the slot 2 is provided with a plurality of circumferentially arranged triangular blocks 3, and the lower end of the plurality of locking blocks 9 is provided with a bevel 10. The bevel 10 cooperates with the inclined end of the triangular block 3, and the plurality of triangular blocks 3 cooperate with the plurality of strip grooves 7 respectively.

[0024] The chamber 12 is provided with multiple sets of circumferentially arranged limiting rods 13. The outer walls of the multiple sets of limiting rods 13 are slidably connected to a sliding plate. Multiple locking blocks 9 are connected to multiple sliding plates respectively. The sliding plates are elastically connected to the inner wall of the chamber 12 by multiple springs 14. By causing the multiple springs 14 to bring the sliding plates back to the starting position, the sliding plates bring the locking blocks 9 back to the starting position, so that the locking blocks 9 are inserted into the locking slots 4 through the strip grooves 7, thereby fixing the connection between the insertion rod 5 and the base 1 and improving the stability of the connection between the two.

[0025] A limiting ring 8 is formed between multiple slots 7. The limiting ring 8 cooperates with multiple triangular blocks 3. By ensuring that all triangular blocks 3 are within the limiting ring 8, the insert rod 5 and the crown 6 are rotated, so that the multiple triangular blocks 3 and the multiple slots 7 are staggered and within the limiting ring 8, and the lower ends of the multiple triangular blocks 3 cooperate with the limiting ring 8, thereby limiting the insertion rod 5 and the slot 2, and realizing the rapid installation of the crown 6.

[0026] When using this invention, the dentist first drills a hole in the affected area of ​​the patient's gum and implants the base 1 into the alveolar bone. Then, the insert 5 is placed into the slot 2, and multiple triangular blocks 3 are placed into multiple strip grooves 7 respectively. The insert 5 is pressed inward so that the triangular blocks 3 contact the inclined surface 10. The insert 5 is then pressed downward. By using the sliding connection between the slide plate and multiple limiting rods 13, the multiple triangular blocks 3 press the multiple locking blocks 9 back into the cavity 12 from the through groove 11. The insert 5 is pressed downward again so that the multiple triangular blocks 3 are all within the limiting ring 8. At this time, the insert 5 and the crown 6 are rotated so that the multiple triangular blocks 3 and the multiple strip grooves 7 are interlaced and within the limiting ring 8, so that the lower ends of the multiple triangular blocks 3 cooperate with the limiting ring 8, thereby limiting the insertion 5 and the slot 2 and realizing the rapid installation of the crown 6.

[0027] At the same time, by rotating the insertion rod 5, the strip groove 7 on the insertion rod 5 and the slot 4 are on the same horizontal plane. Under the elastic action of multiple springs 14 between the slide plate and the chamber 12, the multiple springs 14 bring the slide plate back to the starting position, thereby bringing the slot 9 back to the starting position. The slot 9 is then inserted into the slot 4 through the strip groove 7, thereby fixing the connection between the insertion rod 5 and the base 1 and improving the stability of the connection between the two.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
