Abstract
The utility model provides a dental implant which comprises a bladed part and a columnar component, wherein the bladed part of the dental implant is provided with penetrable holes; the upper surfaces of the penetrable holes face towards perpendicular plane blades; the columnar component passes through an area of a mucous membrane in an extending manner, and is surrounded by a bioinert ceramic ring; the outer surface of the bioinert ceramic ring is made of corrosion-resistant metal such as titanium, tantalum or niobium; and an annular groove is formed on the outer side of the bioinert ceramic ring. In this case, the part inserted into a jawbone is basically bladed, and enters an oral cavity from a protruded part of the jawbone; the dental implant is only loosely fixed at the jawbone, and frequently surrounded by a soft tissue, so that a part of the dental implant in a region penetrates through the mucous membrane in an extending manner, and stimulation of the mucous membrane does not exist; the dental implant is corrosion-resistant; and the service time is prolonged.
Description
Technical field
This utility model relates to a kind of tooth implant.
Background technology
At present, tooth implant will be planted once again every several years.This is that surface due to the implantation body of tooth slowly is corroded, and this may cause the growth of the antibacterial in the intrinsic degree of depth of gingiva, or the stimulation of the tissue in the upper cutaneomucosal zone of gums.For people's health brings injury.
Summary of the invention
In order to overcome defect of the prior art, this utility model provides a kind of tooth implant, particularly corrosion resistant metal tooth implant in vivo.
This utility model solves the technical scheme that its technical problem adopts: this utility model provides a kind of tooth implant, comprises foliaceous part and columnar part.The foliaceous of described tooth implant partly has perforation, and the upper surface of perforation is towards vertical plane leaf; Columnar part is to extend through the area of mucosa, and its ceramic ring by biologically inert surrounds, and in the ceramic ring outside of biologically inert, cannelure is arranged.
In this utility model, the cylindrical part of columnar part comprises blind hole.
In this utility model, the ceramic ring outer surface of biologically inert is by corrosion resistant metal, and as titanium, tantalum or niobium are made,
Like this, the part be inserted at jawbone is foliaceous basically, and ledge enters oral cavity from jawbone, and wherein tooth implant is that loosely is fixed on jawbone, and such tooth implant, often surrounded by soft tissue.This has also caused the part of the tooth implant regional at this to extend through mucosa, so just no longer has the stimulation of mucosa.A cannelure is arranged in the outside of this ring.In order to remain on phase place and any load between healing stage, after being connected to by blind hole of described tooth implant, penetrate mucosa.
The beneficial effects of the utility model are: corrosion-resistant, extend working time.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the axonometric chart of an embodiment of tooth implant of the present utility model.
Fig. 2 is the front view of Fig. 1 partly cut-away.
The specific embodiment
Fig. 1 is the axonometric chart of an embodiment of tooth implant of the present utility model.Fig. 2 is the front view of Fig. 1 partly cut-away.
In Fig. 1, label 1 means the foliaceous part of tooth implant, and label 2 means step, and label 3 means step surface.Foliaceous narrow side surface partly by the respective step shown in numeral 4.In Fig. 1, the foliaceous of described tooth implant partly has perforation 5, and the upper surface 6 of perforation is towards vertical plane leaf.Columnar part 7 is to extend through the area of mucosa 13, and columnar part 7 is surrounded by the ceramic ring 8 of biologically inert, and ceramic ring 8 outer surfaces of biologically inert are by corrosion resistant metal, and as titanium, tantalum or niobium are made, and in ceramic ring 8 outsides of biologically inert, cannelure 9 are arranged.
As shown in Figure 2, the cross section of tooth implant, the cylindrical part 10 of columnar part 7 comprises blind hole 12." active welding " method provides the surface 11 aseptic connections of edgewise circle.
Claims (3)
