Abstract
The utility model discloses a dental implant with unequal-height threads. The dental implant with the unequal-height threads is composed of a foundation pile, a neck part 3 and a body part 4, wherein the foundation pile, the neck part 3 and the body part 4 are in coaxial structures; the foundation pile is divided into a foundation pile upper part 1 and a foundation pile lower part 2; the foundation pile lower part 2 is in a cone-shaped structure; the middle part of the neck part 3 is slightly concave; the body part 4 is provided with unequal-height threads 5 having the heights gradually increased from bottom upwards; a hydroxyapatite filler part 6 is arranged on the body part 4; three parallel transverse annular grooves 7 are formed on the lower part of the body part 4; and a porous tantalum material is distributed in the transverse annular grooves 7. The dental implant with such a structure ensures that the implantation operation is more easier to implement, is quite close in connection with the bone and excellent in structure stability and biocompatibility is greatly improved.
Description
Technical field
This utility model relates to a kind of tooth implant, relates in particular to the tooth implant that a kind of easy realization is implanted, connect closely, steadiness is good, the bio-compatible performance is good.
Background technology
The tooth planting technology has obtained in recent years significant progress and has used widely, has become one of damaged Main Means for the treatment of anodontia and tooth.At present, the tooth implant multi-band of clinical practice has contour thread, and its thread height is constant.Adopt the thread of this structure, jawbone is larger from the incipient stage resistance of body tapping plantation, is difficult for realizing implanting, and needs cost long-time, and will make repeated attempts.And common tooth implant is implanted rear and sclerotin connects defective tightness, and steadiness is not enough; And the material shortage biocompatibility can't guarantee its long-time stability.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide the tooth implant that a kind of easy realization is implanted, connect closely, steadiness is good, the bio-compatible performance is good.
To achieve these goals, this utility model by the following technical solutions: the band not tooth implant of contour thread is comprised of foundation pile, cervical region and body, and described foundation pile, cervical region and body are coaxial configuration; Described foundation pile is divided into foundation pile top and foundation pile bottom, and described foundation pile bottom is round table-like structure; Described cervical region middle part nick; Described body is with the not contour thread that increases gradually highly from the bottom to top; Be provided with hydroxyapatite on described body and fill the position; Described body bottom is distributed with the porous tantalum material with three parallel transverse annular grooves in described transverse annular groove.
As the improvement to the technical program, the porous tantalum porosity that distributes in described transverse annular groove is between 50% and 80%.
As the improvement to the technical program, it is that rectangle is poroid that described hydroxyapatite is filled the position.
Compared with the prior art, this utility model more easily realizes implant procedure owing to having adopted technique scheme, and tightr with the sclerotin connection, stabilized structure is better, and biocompatibility greatly improves.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1 foundation pile top, 2 foundation pile bottoms, 3 cervical regions, the not contour thread of 4 bodies, 5,6 hydroxyapatite are filled position, 7 transverse annular grooves.
The specific embodiment
Below by embodiment, this utility model is carried out concrete description; 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 band is the tooth implant of contour thread not, and as depicted in figs. 1 and 2, the band not tooth implant of contour thread is comprised of foundation pile, cervical region 3 and body 4, and described foundation pile, cervical region 3 and body 4 are coaxial configuration; Described foundation pile is divided into foundation pile top 1 and foundation pile bottom 2, and described foundation pile bottom 2 is round table-like structure; Described cervical region 3 middle part nicks; Described body 4 is with the not contour thread 5 that increases gradually highly from the bottom to top; Be provided with hydroxyapatite on described body 4 and fill position 6; Described body 4 bottoms are distributed with the porous tantalum material with three parallel transverse annular grooves 7 in described transverse annular groove 7.
In order to make more optimized structure, the porous tantalum porosity that distributes in described transverse annular groove 7 is between 50% and 80%.
In order to guarantee its mechanical strength, it is that rectangle is poroid that described hydroxyapatite is filled position 6.
During operation, first bore bone cavity with the plantation drill bit of respective diameters on the jawbone at kind of tooth position, then tooth implant is implanted.Foundation pile top screws in the jaw bones intracavity for connecting mobile phone or pulling tool with tooth implant.Tooth implant has the not contour thread from the body tapping, has reduced the implantation resistance, and implant procedure is more easily realized.The thread path increases from bottom to top gradually, can push sclerotin open to surrounding equably during implantation, makes artificial tooth root fit with sclerotin after implanting jawbone and connect tightr.Vertically anti-spin slot has further reduced the resistance that tapping is implanted, and makes implant procedure more convenient.
The hydroxyapatite of filling and human body hard tissue chemical composition and structure are very approximate, are desirable hard tissue substituting materials, and obvious bone conduction effect is arranged, and make tissue and tooth implant produce good combination, can obviously promote planting effect.
The porous tantalum material of the high-biocompatibility that distributes in the transverse annular groove can start well bone tissue growth, impel newborn sclerotin to pile up, and makes newborn sclerotin form be beneficial to maintenance, and stabilized structure is better.
