Abstract

The utility model discloses a root canal post, which is mainly characterized in that the body of the post is a hollow tube with both ends communicated with each other. The root canal post can not clog the root canal, thereby a complete root canal therapy does not need to be performed before odontoprosthesis, denture restoration can be completed to a patient at the earliest time, requirements on fine shape and functionality of the patient can be met, and both mental and physical impacts caused by missing teeth can be mitigated. Further, the patient implanted with a post can undergo conventional root canal therapy, thereby decreasing medical service cost for patients, improving clinical working efficiency, and lowering the clinical risks.

Description

The root canal dowel pin

Technical field

This utility model relates to the bionical utensil of dental, the dowel pin that particularly uses in prosthodontics.

Background technology

Dowel pin is a kind of bionical utensil that uses in prosthodontics, is used for being inserted in patient's root canal, plays the effect of fixing artificial corona.In the prior art, dowel pin is a solid body, dowel pin will stop up root canal after inserting root canal, cause following problem thus: 1, requiring to suffer from tooth before carrying out prosthodontics must be earlier through perfect root canal, and after the periapical illness is well treated, could be implanted into dowel pin toward root canal, prolong the waiting time of prosthodontics thus; Even 2 through perfect root canal, the tip of a root of suffering from tooth still has infected possibility again, yet the dowel pin of implanting the root pipe bonds with the root pipe, want to take out dowel pin and often need special equipment and technology and abundant clinical experience, and must be cost with the remaining tissue of tooth of sacrificial section, sometimes even at all can't take out dowel pin, can only carry out apicoectomy, cause more injury to the patient.

Summary of the invention

The purpose of this utility model provides the root canal dowel pin that a kind ofly shortens the prosthodontics waiting time, still can carry out conventional root canal after implanting.

For this reason, this utility model is designed to tubular structure with the body of root canal dowel pin, and the two ends of hollow pipe are communicated with.Thus, the dowel pin that inserts in the root canal just can not stop up root canal, before carrying out prosthodontics, also just need not to carry out perfect root canal to suffering from tooth earlier, shortened the waiting time of prosthodontics, even and dowel pin be bonded in the root pipe and also can pass hollow dowel pin with conventional apparatus at any time conventional root canal is carried out at tip of a root position.

The utility model has the advantages that: 1, can shorten the waiting time that patient's tooth is repaired to greatest extent, accomplish timely reparation; 2, solved the contradiction of root canal and repairing and treating, can make the patient finish the reparation of artificial tooth, satisfied its attractive in appearance and needs function, reduced the psychological impact and the physiological effect that bring because of agomphosis in the very first time; 3, still can carry out conventional root canal after implanting dowel pin, alleviate patient's expense of seeking medical advice, improve clinical position efficient, lower clinical risk.

Fig. 1 is a contour structures sketch map of the present utility model;

Fig. 2 is the longitudinal sectional view of Fig. 1.

The specific embodiment

Referring to Fig. 1, Fig. 2, the root canal dowel pin comprises the body of taking root in into root canal 1, and characteristics of the present utility model are that body 1 is a hollow pipe, and the two ends of hollow pipe are communicated with.The general desirable 0.2mm～0.6mm of the internal diameter of hollow pipe.As further improvement, this utility model global formation on body 1 has ring flange 2, offers installing hole 3 on the ring flange.Fixedly pass installing hole with screw during dowel pin ring flange is fixed on the tissue of tooth, can make dowel pin fix more firmly.This utility model can also be provided with screw thread 4 as conventional dowel pin on body, but as further improving, this utility model offers breach 5 on ridge.Can make that like this in the process of inserting dowel pin, the binding agent in the root canal can be extruded root canal by the breach on the ridge, clamp-ons the hollow pipe and the tip of a root to avoid binding agent, and dowel pin can more successfully be inserted in the root canal.

Claims
