Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, and in particular to a composite abutment for dental implants. Background Art

[0002] A dental implant includes a dental crown, an abutment, and an implant body. When implanting a tooth, the implant body is first screwed into the alveolar bone, and the implant body is connected to the alveolar bone by the external threads on its periphery. The abutment is provided with external threads and is threadedly connected to the implant body. Finally, the dental crown (which can be made of materials such as ceramics and titanium alloy) is bonded to the abutment.

[0003] The abutment is usually a personalized product. Its production requires medical staff to scan the position in the oral cavity where the dental implant is located, characteristics such as the inclination angle of the tooth, etc. After being manufactured in the factory, it is then returned to the medical staff. It can be seen that the production cycle of the abutment is relatively long, requiring long-term waiting for both doctors and patients. Moreover, the process is numerous and the cost is relatively high.

[0004] Existing technologies such as Chinese Utility Model Patent Publication Nos. CN218552473U and CN217908029U both relate to composite abutments for dental implants, including a personalized abutment base, a standard docking cap, and a screw. The external threads at the bottom end of the abutment base are connected to the internal threads of the implant body. The standard docking cap is detachably sleeved on the top end of the abutment base. A card slot is provided at the peripheral edge of the top end of the abutment base. A plurality of screw holes are provided at the bottom of one side of the card slot and are spaced apart circumferentially along the abutment base. An installation hole is provided on the side surface of the standard docking cap, and the screw passes through the installation hole and is threadedly connected to one of the screw holes.

[0005] Although the existing technologies disclose the detachable connection between the standard docking cap and the abutment base, the threaded connection method has problems such as complex disassembly and inaccurate positioning. Summary of the Utility Model

[0006] The purpose of the utility model is: aiming at the above problems, the utility model provides a composite abutment for dental implants, which uses a simpler method to connect the base and the base cap, is convenient for positioning, and saves a large amount of time cost.

[0007] A composite abutment for dental implants includes a base and a base cap. The base and the base cap are detachably connected by a thermally deformed claw ring. The thermally deformed claw ring has an inwardly turned claw and an outwardly turned claw. A circular socket for cooperating with the inwardly turned claw is provided at the top of the base, and a circular jack for cooperating with the outwardly turned claw is provided on the base cap.

[0008] Preferably, external threads are provided at the bottom of the base.

[0009] Preferably, a fitting surface for fitting with the bottom of the base cap is provided on the base.

[0010] Preferably, an O-ring seal is provided on the fitting surface.

[0011] Preferably, an adhesive groove is provided on the outer surface of the base cap.

[0012] Preferably, the base further includes a tapered surface with a certain Morse taper that cooperates with the implant.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the present utility model include: replacing the traditional threaded connection with a thermally deformed claw ring makes the disassembly of the base and the base cap simpler and more convenient, and significantly shortens the time for repairing the dental crown.

Detailed Description of the Preferred Embodiment

[0020] The present utility model will be described in detail below with reference to the drawings.

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Figure 1 is an exploded view of a composite abutment for an implant tooth of the present utility model. Figure 2 is an assembly schematic diagram of a composite abutment for an implant tooth of the present utility model.

[0023] As shown in the figure, a composite abutment for an implant tooth includes a base 2 and a base cap 1. The base 2 and the base cap 1 are detachably connected by a thermally deformable claw ring 3. The thermally deformable claw ring 3 has an inwardly turned claw 31 and an outwardly turned claw 32. A circular socket 24 adapted to the inwardly turned claw 31 is provided at the top of the base 2, and a circular jack 12 adapted to the outwardly turned claw 32 is provided on the base cap 1.

[0024] The base 2 is used to connect the implant, and the base cap 1 is used to install the denture. The thermally deformable claw ring 3 is installed on the upper part of the base 2, and the inwardly turned claw 31 of the thermally deformable claw ring 3 is buckled and fixed on the base 1. The base cap 1 is installed on the thermally deformable claw ring 3, and the outwardly turned claw 32 of the thermally deformable claw ring 3 is buckled and fixed on the base cap 1, thereby forming the connection between the base 2 and the base cap 1. The central circular jack 12 at the bottom of the base cap 1 is installed in the central circular socket 24 at the top of the base 2.

[0025] Figure 3 is Figure 1 As shown in the figure, a schematic structural view of the base cap of the composite abutment is shown. As shown in the figure, an adhesive groove 11 is provided on the outer surface of the base cap 1.

[0026] Figure 4 is Figure 1 As shown in the figure, a schematic structural view of the base of the composite abutment is shown. As shown in the figure, an external thread 21 is provided at the bottom of the base 2. The base 2 is connected to the implant through the external thread 21. A fitting surface 23 that fits the bottom of the base cap 1 is provided on the base 2. An O-ring 25 is provided on the fitting surface 23. The O-ring 25 can block the gap between the base cap 1 and the base 2 for blocking and supporting.
