Abstract
The utility model discloses a threaded dental implant, which comprises a body 1, wherein the upper part of the body 1 is cylindrical, and the lower part of the body 1 is conical; triangular thread 2 is arranged on the outer side of the cylinder of the upper part of the body 1; the end part of the lower part of the body 1 is provided with a horizontal through hole 3 and a vertical hole 4; the horizontal through hole 3 and the vertical hole 4 are crossed to be T-shaped and are filled with porous tantalum; and a nanometer apatite coating 5 is arranged on the outer side of the cone of the lower part of the body 1. According to the threaded dental implant of the structure, the stability of the dental implant is improved, the biocompatibility of the dental implant is enhanced, quick bone healing is promoted, and the healing effect is improved, so that the dental implant can quickly play a substitution effect to restore the chawing function after being implanted.
Description
Technical field
This utility model relates to a kind of screw-type tooth implant, relates in particular to a kind of steadiness height, good biocompatibility, screw-type tooth implant that healing effect is good.
Background technology
The tooth planting technology has obtained extensive use clinically as a kind for the treatment of and reparation tooth effective ways damaged or anodontia, has vast potential for future development.
Tooth implant has fundamental influence as a big critical component of tooth planting technology to the success or failure of planting.
There are many defectives in existing tooth implant, and is not enough as hold, steadiness is strong, biocompatibility is not enough, indolence etc., had a strong impact on post-operative recovery and later stage to use.
The utility model content
At the above-mentioned defective that prior art exists, this utility model aims to provide a kind of steadiness height, good biocompatibility, screw-type tooth implant that healing effect is good.
To achieve these goals, this utility model by the following technical solutions: the screw-type tooth implant comprises body; Described body top is cylindrical, and the bottom is conical; The cylinder outside, described body top has angular thread; Described body lower end headband has horizontal through hole and upright opening, and described horizontal through hole and upright opening intersect and be " T " shape, are filled with porous tantalum in described horizontal through hole and the upright opening; The described body lower cone outside is provided with coated with nano-apatite layer.
As the improvement to the technical program, described horizontal through hole and described upright opening are circular hole.
As the improvement to the technical program, described horizontal through hole and described upright opening are rectangular opening.
Compared with the prior art, this utility model has improved the steadiness of tooth implant owing to adopted technique scheme, strengthened its biocompatibility, promoted the sclerotin quickly-healing, improved healing effect, made and to bring into play vicarious function rapidly after the tooth implant plantation, recover masticatory function.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Among the figure: 1 body, 2 angular threads, 3 horizontal through hole, 4 upright openings, 5 coated with nano-apatite layer.
The specific embodiment
Carry out concrete description below by this utility model of embodiment; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of screw-type tooth implant, as shown in Figure 1, the screw-type tooth implant comprises body 1; Described body 1 top is cylindrical, and the bottom is conical; The cylinder outside, described body 1 top has angular thread 2; Described body 1 lower end headband has horizontal through hole 3 and upright opening 4, and described horizontal through hole 3 and upright opening 4 intersect and be " T " shape, are filled with porous tantalum in described horizontal through hole 3 and the upright opening 4; The described body 1 lower cone outside is provided with coated with nano-apatite layer 5.
Described horizontal through hole 3 and upright opening 4 can be circular hole or rectangular opening.Present embodiment adopts circular hole.
Angular thread can be strengthened interlocking, helps the enhancing of tooth implant steadiness.Be cylinder on the tooth implant, be the architectural feature of circular cone down, with human body matching degree height.The porous tantalum of high-biocompatibility and nano-apatite can start bone tissue growth, the molding of guiding sclerotin, accelerate healing, improve healing effect.
