Bone plane root-form dental implant

Abstract

The invention discloses a bone plane root-form dental implant which comprises a dental implant abutment, an implant abutment jack, an implant root and an implant abutment central fixing screw. External threads are arranged at the implant root, a truncated cone is arranged on a lower section of the implant root, a small end of the truncated cone is arranged on the lower side, a threaded surface is arranged on an upper section of a cone surface of the truncated cone, a smooth surface is arranged on a lower section of the cone surface of the truncated cone, rough surfaces are arranged on dental-side surfaces of two edges of the external threads, and rough surfaces are arranged on dental-side surfaces of two edges of threads on the upper section of the cone surface of the truncated cone. The bone plane root-form dental implant has the advantages that the bone plane root-form dental implant is favorable for promoting tissue healing after the dental implant root is implanted in a patient and is particularly favorable for regeneration and bonding of peripheral bone tissues which are flush with interface planes of the implant root abutment; the bone plane root-form dental implant is favorable for early implementing states of 'synosteosis' between the implant root and the tissues; the bone plane root-form dental implant is favorable for acquiring excellent initial retention states, and spinning of the implant under the effect of external force can be prevented; the implant root and the upper abutment can be precisely matched with each other, and accordingly poor conditions such as micro-leakage of interfaces and rotation of the abutment can be prevented.

Description

technical field [0001] The invention relates to a dental implant, in particular to a bone plane root-shaped dental implant. Background technique [0002] In order to prevent the implant from being interfered by masticatory occlusal force or directly affected by excessive occlusal force in the early stage, the dental implant segment is designed into two parts, the root and the abutment, which are connected and fixed with a central screw to form an integral structure. Simulating the shape and structure of natural tooth roots, it is designed in two shapes: conical or cylindrical. [0003] The combined cylindrical threaded root implant is two independent components that separate the implant root part implanted in bone tissue or covered by soft tissue and the implant abutment part exposed in the oral cavity or above the soft tissue covering surface , to be used as a new complete component by means of a central fixing / fastening screw connection combination. According to the morp...

AI Technical Summary

Problems solved by technology

[0006] Most of the existing modular dental implants have smooth surfaces (formed by machining), poor "osseointegration" with surrounding bone tissue (especially in the initial stage of implantation), and friction between contact objects or materials The coefficient is small, and it is prone to spin phenomenon
