Abstract
The utility model discloses a 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; the lengths of the upper part and the lower part of the body 1 are equal; the body 1 is provided with external threads 2; a cross intersecting through hole 3 is formed in the end of the lower part of the body 1and is filled with porous tantalum. By adopting the dental implant with the structure, the adaptability of the dental implant to the human bone is improved, so that the implanting process is convenient with less injury, the retention effect of the dental implant is enhanced, the biological compatibility of the dental implant is improved, and the implant is firm and durable in the oral cavity.
Description
Technical field
This utility model relates to a kind of dental implant, relates in particular to that a kind of fitness height, retention effect are good, the dental implant of good biocompatibility.
Background technology
The tooth implanted prosthetics is in advanced position as a kind for the treatment of and reparation tooth effective ways damaged or anodontia in the every clinical means of dental care, have vast potential for future development.
But existing tooth implanted prosthetics is strict to sclerotin, and relevance grade is not high, and is bigger to bone destruction, the operation technique complexity.And the biocompatibility of dental implant is relatively poor, synosteosis power deficiency, and retention effect is not good.
The utility model content
At the above-mentioned defective that prior art exists, this utility model aims to provide that a kind of fitness height, retention effect are good, the dental implant of good biocompatibility.
To achieve these goals, this utility model by the following technical solutions: dental implant comprises body; Described body top is cylindrical, and the bottom is conical; Described body upper and lower equal in length; Described body has external screw thread; Termination, described body bottom is provided with and is the through hole that " ten " word intersects, and is filled with porous tantalum in the described through hole.
As the improvement to the technical program, described external screw thread is rectangular thread.
As the improvement to the technical program, described body lower cone tapering is between 2 ° and 33 °.
Compared with the prior art, this utility model is owing to adopted technique scheme, improved the fitness of dental implant to the human body sclerotin, make implantation process convenient, the damage littler, strengthened the retention effect of dental implant, strengthened the biocompatibility of dental implant, made dental implant more firm durable in the oral cavity.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Among the figure: 1 body, 2 external screw threads, 3 through holes.
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 dental implant, as shown in Figure 1, dental implant comprises body 1; Described body 1 top is cylindrical, and the bottom is conical; Described body 1 upper and lower equal in length; Described body 1 has external screw thread 2; Termination, described body 1 bottom is provided with and is the through hole 3 that " ten " word intersects, and is filled with porous tantalum in the described through hole 3.
In order to increase contact area, to strengthen interlock, described external screw thread 2 is rectangular thread.
For fully adapting to organization of human body, described body 1 lower cone tapering is between 2 ° and 33 °.
Be cylinder on the dental implant, be the architectural feature of circular cone fully to have adapted to the shape of human body dentale down, thus when having reduced operation to the damage of sclerotin, improved the fitness of implant surgery, simplified operation technique.Simultaneously, the porous tantalum material has very strong biocompatibility, can promote bony fusion after the implantation, strengthens synosteosis power, has improved retention effect greatly.
