Dental implant

Abstract

The invention relates to a dental implant, which comprises a dental implant body (1), a retaining abutment (2) and a false tooth (3). The dental implant is characterized in that a through hole (4) is formed in the head of the retaining abutment (2), wherein a spring (5) is arranged in the through hole (4); a sliding block (6) is arranged at each of the two ends of the spring (5); grooves (10) for arranging the spring (5) are formed in the sliding blocks (6); embedding grooves (7) for arranging the sliding blocks (6) are formed in the false tooth (3); the dental implant body (1) is a porous tantalum part with porosity of 60 to 70 percent, and consists of a neck (11), a middle (12) and a tail (13); an ordinary thread (14) is formed on the outer surface of the middle (12); a penetration hole (8) which is vertically through is formed in the dental implant body (1); a flow guide groove communicated with the penetration hole (8) is formed in the bottom end face of the dental implant body (1). According to the dental implant, the retaining abutment is closely connected with a dental crown, the dental implant body and an alveolar bone, and the dental implant is reasonable in structure and high in biocompatibility.

Description

technical field [0001] The present invention relates to artificial dental implant in oral cavity, in particular to a dental implant. Background technique [0002] Most of the dental implants used in oral implant surgery currently include implants, retained abutments and dentures. After the implant body is pre-embedded in the gum, a retention abutment is installed above it, and the retention abutment is exposed on the surface of the gum and the denture is installed, so as to realize the implantation of the denture. [0003] The connection between the retention abutment and the denture is often a direct plug-in connection, which has poor resistance to axial rotation, and there are problems such as insufficient connection, easy loosening and falling off; at the same time, its structure is between the bone tissue of the human body. The stability of the connection is poor; after implantation, it is not possible to add other substances such as biological factors to increase the s...

AI Technical Summary

Problems solved by technology

[0003] The connection between the retention abutment and the denture is often a direct plug-in connection, which has poor resistance to axial rotation, and there are problems such as insufficient connection, easy loosening and falling off; at the same time, its structure is between the bone tissue of the human body. The stability of the connection is poor; after implantation, it is not possible to add other substances such as biological factors to increase the stability of the implant at the weak bone such as the bottom

[0004] In addition, there are certain defects in the structure setting of the existing dental implants, resulting in poor mechanical properties and biocompatibility, and will repel with human tissues after long-term use, which will affect its service life and other problems.
