Problems solved by technology

Therefore, in the technique of Patent Document 1, there is a problem that the effect of inhibiting bacterial growth and the effect of alleviating inflammation cannot be maintained for a long period of time.
In addition, since lactoferrin may reduce the affinity between the dental implant and the jawbone, when the entire dental implant is coated with lactoferrin, the jaw bone embedded part of the dental implant may Possibility of decreased bond strength due to impaired affinity to jawbone
[0011] The technology described in Patent Document 2 improves the thread shape of the dental implant fixture. However, it is actually difficult to prevent bacteria that invade the gap between the gum and the dental implant from infecting the jawbone only with this technology.
That is, the technique of Patent Document 2 is not sufficiently effective as a preventive measure for implant periodontitis

Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] figure 1 It is a partial cross-sectional view illustrating a state of use of the dental implant 10 according to one embodiment of the present invention. As shown in this figure, the dental implant 10 is used to fix a dental prosthesis 30 such as a denture in the oral cavity, and is made of a material that has excellent affinity with bone and has sufficient strength, such as titanium and titanium alloys. , ceramics, etc.

[0035] Such as figure 1 As shown, the dental implant 10 of this embodiment has: a jaw embedded portion 11 embedded in the jawbone G and in contact with the jawbone G; The gingival contact part 12, and the prosthesis support part 13 which attaches and supports the dental prosthesis 30, such as a denture, are attached.

[0036] The jaw implantation part 11 includes: a base end part 11b, which is mainly in contact with...

Abstract

The present invention relates to a dental implant which can prevent peri-implant diseases, and of which the affinity of a jaw bone implantation part that is to be implanted into a jaw bone for a jaw bone is not inhibited. In the dental implant (10), at least a region (12a), which is a region to be in contact with a gum (D), of a gum contact part (12) is anti-bacterially treated, and the region (12a) has an arithmetic average roughness (Ra) of 2 mum or less. At least the region (12a) of the gum contact part (12) is imparted with an anti-bacterial property, and has a surface shape onto or on which bacteria rarely adhere or remain and which can contact closely with a gum (D).

Description

technical field [0001] The present invention relates to a dental implant embedded in a jawbone to fix dental prostheses such as dentures in the oral cavity. Background technique [0002] In the case of missing teeth, in order to supplement the functions of the teeth, an implant operation of embedding a dental implant in the jawbone and fixing the dental prosthesis to the dental implant is increasingly used. [0003] However, it is known that implant periodontitis, a symptom very similar to periodontitis of natural teeth, occurs after dental implant surgery. The reason for this is considered to be that bacteria in the oral cavity invade the gap between the gum and the dental implant to form a focus of infection (bacteria), resulting in inflammation. When symptoms develop, the jaw bone in contact with the dental implant dissolves, and finally, the surrounding jaw bone supporting the dental implant disappears, thereby possibly causing a problem that the dental implant falls ou...
