Abstract
The utility model relates to a high-intensity self-tapping dental implant in the technical field of dental implantation. The utility model is characterized in that the upper part of a retention pin and the lower part of a base station are combined through an inner pentapetalous keyway and a pentapetalous key, and the lower part of a central screw of the base station is provided with a section of smooth cylinder sections which can be tightly matched with internal threads of the retention pin. After the implant is additionally provided with an outer hexapetalous tray and the length of the retention pin is changed, the utility model can be also used for the retention of skull operations. The utility model is firm and durable, and a masticatory function of the dental implant is approximate to the masticatory function of a dermal tooth; the utility model has low cost which is one tenth of the cost of an imported implant; therefore, the utility model is greatly welcomed by extensive patients.
Description
This utility model belongs to tooth planting technology field, relates to a kind of high strength self-taped type tooth implant.
Because pure titanium material has excellent biological compatibility, behind the implant into body can with osseous tissue, mucosal tissue and skin form good interface, can remain in the human body jawbone for a long time, thereby in recent years, by the pure titanium material spiral-shafted implant of Sweden Branemark initiative by universally acknowledged and obtain general employing.This implantation body is used in the effective two phases method Dental Implant operation of having been generally acknowledged by medical circle, and its success rate is very high.But, the case of many failures is also arranged.The reason of failure, except other medical science, operation factor, still main because some structural design of this implantation body is unreasonable.For example, adopt very little interior six sides and six sides of diameter to socket-connect between the retention pin of implantation body and the base station, difficult cover, difficulty are unloaded, and be not easy to judge whether to be in place very much, make the base station center bolt can not be screwed to the end, thereby cause the implantation body of implantation and base station not to be combined, the operation back is stressed once chewing, just take place to become flexible, make the center bolt fracture, cause the Dental Implant failure.In addition, because the restriction of implant retention nail internal diameter makes that the diameter of center bolt and crane span structure retaining screw is less than normal, also be the reason that causes fracture.This phenomenon of rupture has illustrated that this class implantation body has problems aspect structural strength.And adopt two phase tritons to revolve plantation series, have seven other parts (or laying down) will be installed like clockwork, for the implantation body that implants in the alveolar bone, its whole height and diameter all are subjected to strict restriction because of the intensity (alveolar wall thickness degree) that can not reduce alveolar bone.Therefore, do not changing under the preceding topic of implantation body's material, it obviously is impossible increasing its mechanical strength by the size that strengthens other parts simply, and only way has only the redesign by other modular construction.
At above-mentioned the problems of the prior art, the purpose novel in this reality is: provide a cover not change raw material, do not change implantation body's parts in addition of the new construction of external dimensions, it is installed firmly, force-bearing situation is good, and mechanical strength is big, and makes things convenient for operation technique.
Now this utility model technical solution is described below:
This utility model implantation body is made of retention pin (1), base station (2), base station center bolt (3), crane span structure adapter ring (4), crane span structure fixed screw (5), topped nut (6), healing nut (7).Have the screw tap sword of being convenient to shoot in the alveolar bone on the retention pin (1); The base station center bolt is equipped with the silicon rubber loop that seals on (3); Topped nut (6) and healing nut (7) are to prevent in the two operations process that osseous tissue from growing in retention pin (1) and the base station center bolt (3) and the nut that plays the covering effect of installation temporarily.It is characterized in that: the bottom of the top of retention pin (1) and base station (2) is from combining with interior five splines and five splines, and retention pin (1) internal thread internal diameter is slightly less than five spline internal diameters; The top of base station center bolt (3) is outer five splines, can match with interior five splines in the operation tool, the bottom be screwed into by base station (2) have on the screw section of retention pin (1) female thread one section slick, can with the leakproof fit shell portion of retention pin (1) female thread (8); All have on topped nut (6), healing nut (7) and the crane span structure fixed screw (5) and be convenient to twist " cross " shape screwdriver slot (9) that opens.
This utility model implantation body parts in addition not only can be used as in tooth and the root of the tooth implantation alveolar bone, also can be used on the very thin skull of osteoplaque as retention pin (referring to Fig. 8).Top design has six floral discs, can increase the contact surface with osseous tissue, avoids penetrating when being subjected to unexpected strength the bone wall.During actual the use, only need the corresponding minimizing of length of retention pin (10) is got final product, the parts in the above-mentioned implantation body of the optional usefulness of other accessories, its part dimension also can be adjusted accordingly.
Now that description of drawings is as follows:
Fig. 1: this utility model implantation body five covers shaft side figure.
Fig. 2: interim topped nut that uses and healing nut in the two phase method operation processs.
Fig. 3: can be used for the retention pin in the skull, (other accessories are selected above-mentioned parts for use).
Wherein: (1) retention pin (2) base station (3) base station center bolt (4) crane span structure adapter ring
(5) the topped nut of crane span structure fixed screw (6) (7) healing nut (8) circle
Column body segment (9) cruciform screw driver groove (10) is used for the retention pin on the skull
(11) outer six floral discs
The superiority that the utility model is compared with prior art is:
(1) increased fixedly spiral shell of planting body overall mechanical strength and base station center bolt, crane span structure Silk, the mechanical strength of itself;
(2) increased the close fit degree of retention pin, base station and base station center bolt;
(3) make things convenient for operation technique, can not produce incomplete phenomena, and installed, unloaded opening Just, kit is capable.
This utility model implantation body is through clinical use, and effect is quite desirable, and not only sturdy and durable, masticatory function is similar to dermal tooth, and cheap, only is 1/10th of import implantation body, thereby is subjected to the welcome of extensive patients deeply.
Claims (2)
1, a kind of dentistry is planted tooth implant, by retention pin (1), base station (2), base station center bolt (3), crane span structure adapter ring (4), crane span structure fixed screw (5), topped nut (6), healing nut (7) constitutes, and retention pin has the screw tap sword on (1), it is characterized in that: the top of retention pin (1) is spent strong combining with the bottom of base station (2) with interior five splines and five, and the minor diameter of internal thread of retention pin (1) is slightly less than five spline internal diameters; The top of base station center bolt (3) is outer five splines, the bottom be screwed into by base station (2) have on the screw section of retention pin (1) female thread one section slick, can with the leakproof fit shell portion of retention pin (1) female thread (8);
2, a kind of dentistry according to claim 1 is planted tooth implant, it is characterized in that: all have on topped nut (6), cover screw fixture cover (7), the crane span structure fixed screw (5) and be convenient to twist " cross " shape screwdriver slot that opens.
