Abstract
The utility model discloses a combined type dental implant component which comprises a dental implant body, a dental implant front end portion and a porous tantalum structure. The dental implant front end portion is connected with the hollow cylindrical porous tantalum structure through a boss on the dental implant front end portion, a thread is arranged on the portion of a small cylinder of the boss exceeding the height of the porous tantalum structure, the dental implant front end portion is connected with is connected with a threaded hole on the dental implant body through the thread, a central vertical channel is arranged in the dental implant front end portion, one to a plurality of horizontal channels are arranged at the tip of the dental implant front end portion, the central vertical channel is respectively connected and communicated with one ends of the horizontal channels, and the other ends of the horizontal channels are evenly distributed around the dental implant front end portion. The dental implant component of the structure overcomes the phenomenon that a bone substance is displaced by an implant, promotes rapid fusion of the dental implant component and bone tissue, enhances biocompatibility, and improves implantation success rate.
Description
Technical field
This utility model relates to a kind of tooth implant member, relates in particular to a kind ofly to overcome sclerotin and passed, promote structure fusion, good biocompatibility, the tooth implant member that the plantation success rate is high by implantation body.
Background technology
At present, oral cavity implanting tooth is widely applied clinically as a kind of very effective method of repairing mouthful interior anodontia.This method is that Dental Implant is implanted the bony fusion that makes Dental Implant and patient in the alveolus, thereby reaches the healing purpose.
The tooth implant member is the critical component of Dental Implant.In general, the tooth implant member is divided into base station, cervical region and body three parts from outside to inside.Wherein, base station directly links to each other with artificial artificial tooth, and body then gos deep in the alveolar bone compatible with osseous tissue; Base station links to each other by cervical region with body.
Traditional Dental Implant system often causes the plantation success rate low because structure adaptability is poor, and biocompatibility is not high.The special areas such as district of grinding one's teeth in sleep at upper chin, because the maxillary sinus relation is arranged, sclerotin is plentiful not usually, tooth-implanting operation is very easily failed.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide and a kind ofly overcomes sclerotin and passed, promote structure fusion, good biocompatibility, the tooth implant member that the plantation success rate is high by implantation body.
To achieve these goals, this utility model by the following technical solutions: combination type tooth implant member comprises tooth implant body, tooth implant leading section and porous tantalum structure; Described tooth implant leading section is connected with the porous tantalum structure that is hollow circular cylinder by the boss on it; The part that described boss small cylinder exceeds the porous tantalum structure height is provided with screw thread, and described tooth implant leading section is connected with screw on the described tooth implant body by described screw thread; Establish the central vertical passage in the described tooth implant leading section, one or more horizontal channel is established at the most advanced and sophisticated position of described tooth implant leading section, described central vertical passage is connected conducting with described horizontal channel one end respectively, and the other end of described horizontal channel is evenly distributed on around the described tooth implant leading section.
As the improvement to the technical program, described horizontal channel is 4.
As the improvement to the technical program, described central vertical passage and horizontal channel are cylindrical-shaped structure.
Compared with the prior art, this utility model is owing to adopted technique scheme, overcome the phenomenon that sclerotin is passed by implantation body, avoided that implantation body's one side seam is more plentiful, the appearance of the weaker phenomenon of another side seam, promoted the rapid fusion of tooth implant member and osseous tissue, strengthened the biocompatibility of tooth implant member, Effective Raise the success rate of Dental Implant.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment tooth implant member.
Among the figure: 1 tooth implant body, 2 tooth implant leading sections, 3 central vertical passages, 4 horizontal channels, 5 porous tantalum structures, 6 boss.
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 combination type tooth implant member, as shown in Figure 1, described combination type tooth implant member comprises tooth implant body 1, tooth implant leading section 2 and porous tantalum structure 5.Described tooth implant leading section 2 is connected with the porous tantalum structure 5 that is hollow circular cylinder by the boss 6 on it.The part that described boss 6 small cylinders exceed porous tantalum structure 5 height is provided with screw thread, and described tooth implant leading section 2 is connected with screw on the described tooth implant body 1 by described screw thread.Establish central vertical passage 3 in the described tooth implant leading section 2, one or more horizontal channel 4 is established at described tooth implant leading section 2 most advanced and sophisticated positions, described central vertical passage 3 is connected conducting with described horizontal channel 4 one ends respectively, and the other end of described horizontal channel 4 is evenly distributed on around the described tooth implant leading section 2.
For easily manufactured, contact surface is abundant, preferred 4 of the quantity of described horizontal channel 4.
For the ease of processing, described central vertical passage 3 and horizontal channel 4 preferred cylindrical-shaped structures.
Combination type tooth implant element structure is simple, manufacturing and easy to assembly.Establish central vertical passage and horizontal channel in the tooth implant leading section, increased the permeability of structure, be conducive to start bone growth.The horizontal channel is evenly distributed on around the tooth implant leading section, so that tooth implant member and sclerotin merge better.Simultaneously, porous tantalum structure between tooth implant body and the tooth implant leading section has played the effect that promotes that bone growth, promotion tooth implant member and osseous tissue fully merge, greatly strengthen biocompatibility and the adaptability of tooth implant member, improved the plantation success rate.
