Artificial dental implant

Abstract

The invention provides an artificial dental implant. The artificial dental implant comprises an implant body and an abutment, wherein the implant body is provided with a central conical hole formed in the axial direction of the implant body; a plurality of layers of wing plates which are arranged at intervals in the axial direction are formed on the circumferential outer side surface of the implant body; various layers of wing plates surround the circumferential direction of the implant body by a circle; a space between every two adjacent layers of wing plates forms an occlusion groove; the abutment is solid; and an implant connecting portion of the abutment is inserted into the central conical hole and is in interference fit with the central conical hole. The artificial dental implant is convenient to implant, the initial stability does not need to be guaranteed, the implantation depth is reduced, the requirement on bone mass is low, and the clinical application range can be widened; the abutment is inserted into the implant body and is in interference fit with the implant body, the abutment on the upper portion is inserted into the implant body on the lower portion and is knocked in place, the upper portion and the lower portion are locked by virtue of taper, the operation is extremely simple, the implant is tighter when used, the static connection effect is achieved, the connection is reliable, cuff soft tissues can be kept healthy and stable, inflammation is avoided, and the service life of the artificial dental implant is prolonged.

Description

technical field [0001] The invention belongs to the technical field of stomatology, and in particular relates to the structural improvement of artificial tooth implants. Background technique [0002] Dental implant refers to a method of restoring missing teeth based on the underlying structure implanted in bone tissue to support and retain the upper tooth restoration. It uses artificial materials (such as metal, ceramics, etc.) to make artificial dental implants (generally similar to tooth roots), which are surgically implanted into tissues (usually the upper and lower jaws) and obtain firm retention support from bone tissue. Means and means of connecting and supporting the upper part of the dental restoration. Artificial tooth implants can achieve a restoration effect that is very similar to natural teeth in terms of function, structure, and aesthetics, and have become the preferred restoration method for more and more edentulous patients. [0003] Most of the existing de...

AI Technical Summary

Problems solved by technology

[0005] The prior art has the following disadvantages and deficiencies: 1. The implant is screwed into the alveolar bone implant socket through a helical structure. It is necessary to ensure the initial stability of the implant, so the required screwing depth is large and the pitch of the thread is wide, so that the alveolar bone For edentulous patients with small bone thickness, the feasibility of artificial dental implants is low, and even if it is feasible, it is difficult to ensure the initial stability of implant placement, and it is difficult to ensure the firm retention of final artificial dental implants ;

[0006] 2. The screw thread of the implant has a large depth and a wide pitch, resulting in poor blood circulation;

[0007] 3. The thread is screwed into the cut bone, which will easily lead to the compression and absorption of the bone;

[0008] 4. The hollow abutment is fixed on the implant through the central screw. For the strong occlusal force countless times a day, there is a risk of loosening of the screw and the connection with the implant. Once the connection between the abutment and the implant becomes loose, and the implant If the top of the body is lower than the bone plane of the alveolar bone, there will be an inflammatory reaction at the bone interface and bone resorption. In order to avoid this problem as much as possible, in the prior art, it is necessary to ensure that the top of the implant is flat with the bone plane. It is not easy to form a sufficient amount of soft tissue above the implant, which is not conducive to the stability of the cuff, and the cuff is unstable and prone to inflammation;
