Abstract
The utility model discloses a dental implant with a gradually heightened screw tooth. The dental implant with the gradually heightened screw tooth comprises 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 of coaxial structures; the foundation pile is divided into a foundation pile upper part 1 and a foundation pile lower part 2, and the foundation pile lower part 2 is of a round platform-like structure; the middle part of the neck part 3 is slightly concave; the body part 4 has the non-equal-height screw tooth 5 with the height which is gradually increased from bottom to top; and a porous tantalum layer 7 is embedded at the end of the body part 4, a central vertical channel 6 is arranged at the end of the body part 4, and porous tantalum is filled in the central vertical channel 6. The dental implant with the structure can simplify the operation of implant surgery, enable the linkage of the dental implant and bone to be more sable, reduce the looseness rate and enable the structure to simultaneously realize biocompatibility and mechanical properties.
Description
Technical field
This utility model relates to a kind of tooth implant, relate in particular to a kind of operation technique simple, connect that steadiness is good, the rate that gets loose is low, tooth implant that biocompatibility and mechanical property have concurrently.
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, on the clinical tooth implant of generally using with thread mostly be contour formula, highly not variation.This will cause the comparison of resistance that the implant operation starting stage runs into large, and implanting difficulty increases.
And common tooth implant implantation is rear and the sclerotin connection is firm not, easily gets loose; And the biocompatibility that material shortage is enough only possesses single mechanical property.
The utility model content
In view of the foregoing defects the prior art has, this utility model aim to provide a kind of operation technique simple, connect that steadiness is good, the rate that gets loose is low, tooth implant that biocompatibility and mechanical property have concurrently.
To achieve these goals, this utility model by the following technical solutions: the laddering tooth implant of thread height 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; Described body termination is embedded with the porous tantalum layer, and described body termination is provided with the central vertical passage, is filled with porous tantalum in described central vertical passage.
As the improvement to the technical program, described central vertical passage is circular hole.
As the improvement to the technical program, in described porous tantalum layer and described central vertical passage, the porosity of porous tantalum is between 50% and 80%.
Compared with the prior art, this utility model has been simplified the implant surgery operation owing to having adopted technique scheme, tooth implant and sclerotin is connect more firm, has reduced the rate of getting loose, and makes structure have biocompatibility and mechanical property concurrently.
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 central vertical passages, 7 porous tantalum layers.
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: the laddering tooth implant of a kind of thread height, as depicted in figs. 1 and 2, the laddering tooth implant of thread height 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; Described body 4 terminations are embedded with porous tantalum layer 7, and described body 4 terminations are provided with central vertical passage 6, are filled with porous tantalum in described central vertical passage 6.
For the ease of implementing processing, described central vertical passage 6 is circular hole.
In order to make more optimized structure, in described porous tantalum layer 7 and described central vertical passage 6, the porosity of porous tantalum is between 50% and 80%.
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.Not contour thread has reduced the implantation resistance, has simplified the implant surgery operation.Vertically anti-spin slot has further reduced tapping and has implanted resistance, makes implant procedure convenient.
The thread path increases from bottom to top gradually, can push sclerotin open to surrounding equably during implantation, make artificial tooth root after implanting jawbone with sclerotin fit better, the space is less, it is more firm to connect, and has effectively prevented the generation that gets loose.
When possessing complete mechanical property, the porous tantalum material can be realized stronger biocompatibility.The porous tantalum material can start well bone tissue growth, promotes newborn sclerotin to pile up, adjust newborn sclerotin form, and this will be beneficial to post-operative recovery, consolidate surgical effect.
