Abstract
The utility model discloses a novel self-tapping and self-positioning tooth implanting body, which is composed of a spline screw cap, a center screw, a foundation pile and a position fixing nail. The utility model is characterized in that a shoulder desk with inner conical teeth is positioned at the upper end of the position fixing nail. The foundation pile with outer conical teeth is inserted with the inner conical teeth of the shoulder desk. The utility model has the advantages of easy manufacture for the tooth implanting body, firm positioning, low price, reasonable structure, convenient operation, and wide application through the improved design of the utility model.
Description
Technical field
This utility model belongs to the Dental Implant technical field in the stomatology, relates to a kind of novel self tapping and makes the bit-type tooth implant by oneself.
Background technology
Since the pure titanium material spiral-shafted implant of Sweden Branemark initiative by since universally acknowledged, obtained good therapeutic treatment effect, obtained general application.In the domestic and international prior art before this utility model, be applicable to more existing reports of tooth implant of two phases method operation.Wherein the applicant's " attacking implantation body of stricture of vagina type tooth section from body " (patent No. 932160514), " high strength self-taped type tooth implant " (patent No. 952452812) all have excellent biological compatibility and mechanical strength, maintenance is good, corrosion-resistant, can form good interface with osseous tissue, mucosal tissue and skin behind the implant into body, can remain on for a long time in the human body jawbone.But, also increasing along with the quick increase of the number of seeking medical advice to the demand of tooth implant, in the operation process of a large amount of enforcement two phase methods, also expose the weak point of this tooth implant gradually.For example: during one-stage operation, retention pin has been implanted in the alveolar bone, secondary operation need be installed in foundation pile on the staple soon, but oral environment is narrow and small, the retention pin of having implanted is difficult to see clearly, operate with the sensation of surgical staff entirely, the installation of foundation pile is wasted time and energy, simultaneously, patient's alveolar bone retention pin plantation angle bad or one-stage operation is bad running into, and can cause front tooth crooked, in the case, generally the tooth foundation pile epimere on implantation body top is made the shape of the certain angle that slopes inwardly, but can not be made it that change of the big anglec of rotation is arranged when adjusting.And in the above-mentioned patented technology, retention pin combines with five splines with foundation pile, is not easy the location to fashionable, and angle is bigger when adjusting, and therefore, makes that the involutory time of operation is long, operating difficulties, and angle is difficult for adjustment, and degree of accuracy is poor.
Summary of the invention
At above-mentioned weak point of the prior art, the purpose of this utility model is to provide a kind of more reasonable structure, is easy to processing, and firm position, low price make things convenient for the novel self tapping of operation technique to make the bit-type tooth implant by oneself.Now this utility model technical solution is described below:
This utility model is made of spline nut, center bolt, foundation pile, retention pin; The retention pin epimere is a shoulder, is threaded on the cylindrical, vertically has the screw tap sword, it is characterized in that: the foundation pile hypomere has the outer cone tooth, shoulder has the inner cone tooth, and the shoulder that has the inner cone tooth is positioned at the upper end of retention pin, and the foundation pile of band outer cone tooth and the inner cone tooth of shoulder are pegged graft; Fuse by center bolt that has spline nut and silicon rubber loop and retention pin.In order to be applicable to the reparation of craniofacial defect, also the enlarged diameter of shoulder upper end can be become plate-like, the unlikely bone wall that penetrates when being beneficial to the maintenance of retention pin and being subjected to external force in implantation body.

Fig. 2: cranium face retention pin schematic appearance
Fig. 3: band angle of inclination tooth foundation pile sketch map
Wherein: (1) spline nut (2) silicon rubber loop (3) center bolt (4) foundation pile (5) outer cone tooth (6) inner cone tooth (7) shoulder (8) retention pin (9) awl sword (10) screw thread
The specific embodiment
When implementing the one-stage operation of tooth plantation, at first plant in alveolar bone with the retention pin (8) that has the screw tap sword, during secondary operation, in the shoulder (7) on foundation pile (4) the insertion retention pin (8), make inner cone tooth (6) and outer cone tooth (5) strong bonded, then center bolt (3) and retention pin (8) are linked into an integrated entity, be with silicon rubber loop (2) under the spline nut (1) on center bolt (3) top.
Because this utility model has designed interpolation type awl toothing at the retention pin epimere, with the awl tooth socket of foundation pile after, make intensity bigger, operate easylier, and made things convenient for the direction adjustment of superstructure, clinical use is more extensive, convenient, performance is better.
Claims (2)
1, a kind of novel self tapping is made the bit-type tooth implant by oneself, is made of spline nut, center bolt, foundation pile, retention pin; The retention pin epimere is a shoulder, is threaded on the cylindrical, vertically has the screw tap sword, it is characterized in that: the foundation pile hypomere has the outer cone tooth, shoulder has the inner cone tooth, and the shoulder that has the inner cone tooth is positioned at the upper end of retention pin, and the foundation pile of band outer cone tooth and the inner cone tooth of shoulder are pegged graft; Fuse by center bolt that has spline nut and silicon rubber loop and retention pin.
2, novel self tapping according to claim 1 is made the bit-type tooth implant by oneself, it is characterized in that: when being used for the reparation of craniofacial defect, the enlarged diameter on the shoulder is become plate-like.
