Abstract
One has core taper zirconium oxide root canal pile to follow closely, and belongs to prosthetic dentistry technical field.Integrated oxidation zirconium root canal pile nail is for circular cone or truncated cone structure, and have the core of through hole at zirconium oxide pyramidal structure center, described core also be circular cone or truncated cone structure, hat side slightly, root side thin through whole zirconium oxide root canal pile pin structure; Stake, core, corona reparation is done with this stake, when root canal failure, perfect Endodontic retreatment can be carried out by the core taking out zirconium oxide root canal pile without the need to taking out stake, can increase work efficiency, the side avoiding root canal pile to bring is worn, odontoclasis equivalent risk, reduce psychological impact and physiological effect that unnecessary process brings to patient, alleviate patient and to seek medical advice expense, improve the work efficiency of doctor.
Description
Technical field
This utility model belongs to prosthetic dentistry technical field, includes core zirconium oxide root canal pile, for the technical field of tooth stake, core, hat reparation and Endodontic retreatment.
Background technology
PSZ is applied in Oral Repair more and more widely with its excellent mechanical performance, biocompatibility and aesthetic property, and be applied to clinical as root canal pile, root canal pile is in insertion tooth root pipe, is bonded together by adhesives and tooth, to obtain the device of maintenance, but when root canal unsuccessfully needs to re-start root canal, root pipe is needed again to get through, way routine clinical at present is bit by bit ground off by dowel pin high speed turbine, and the shortcoming done like this is; (1) waste time and energy, zirconium oxide is stone, and it is very difficult in fact grinding off it; (2), when grinding off stake, easily cause the side of root canal wall to be worn, cause unnecessary misery to patient.Certain removal root canal pile, also the bonding agent between dowel pin and root inside pipe wall bit by bit can be removed, then dowel pin is taken out, this also increases the risk that root canal wall side is worn, too increase the risk of Tooth root fracture, traditional root canal pile and Therapeutic mode are shown in Fig. 2 and Fig. 3 simultaneously.
Utility model content
This utility model object is for removing the risk and burden that root canal pile brings when again re-starting root canal after root canal failure after preventing tooth stake, core, hat reparation, and design has core taper zirconium oxide root canal pile, after can be used in post-core prosthesis, root pipe is treated simply again, increases work efficiency and medical effect.Particularly by the taper zirconium oxide root canal pile structure being designed with core, during application, the narrow of tapered pile is in the tip of a root direction of tooth, consistent with the structure of tooth root pipe, when needs Endodontic retreatment without the need to this root canal pile is removed, only the core of root canal pile analog such as () gutta-perchas need be taken out, can Endodontic retreatment be carried out.
For achieving the above object, the technical solution adopted in the utility model is as follows.
A kind of to facilitate the zirconium oxide root canal pile nail of Endodontic retreatment after tooth post-core prosthesis, it is characterized in that: integrated oxidation zirconium root canal pile nail is circular cone or truncated cone-shaped structure, the core of through hole is had at zirconium oxide pyramidal structure center, described core is also circular cone or truncated cone structure, and hat side is thick, root side is thin through whole zirconium oxide root canal pile pin structure; In-core is filled with canal filling material.
Zirconium oxide root canal pile nail outer surface can in coarse, thread-like structure.Preferably the tapering of core is less than the tapering of integrated oxidation zirconium root canal pile nail further, is conducive to the mechanical property strengthening dowel pin hat side.
The size of integrated oxidation zirconium root canal pile nail of the present utility model and the large I of core are according to practical situation manufacture.
One of the present utility model has core taper zirconium oxide root canal pile nail tool to have the following advantages:
(1) have circular cone or the circular cone structure of core, this core is also the structure through whole pile body that hat side is thick, root side is thin, is conducive to if desired taking out.
(2) pile body is the zirconium oxide of good mechanical properties, and core can be the conventional material of clinical root-canal filling, as gutta-percha etc., is conducive to if desired taking out, during without the need to doing Endodontic retreatment can persistence in vivo.
(3) maintenance that thick, lower fine texture is conducive to nuclear material is presented by pile body hat side.
(4) pile body outer surface in coarse, thread-like structure, can be conducive to the cemented retention with root canal wall.The technical characteristic of this utility model method is mainly:
(1) utilize PSZ with its excellent mechanical performance, even if there is the zirconium oxide dowel pin of core, its mechanical performance also can meet clinical needs.
(2) this dowel pin outward appearance and core all become cone-shaped, closer to the form of tooth root pipe, are conducive to row root canal and maintenance again.
(3) post-core prosthesis of tooth is carried out with this kind of dowel pin, root canal failure again row root canal time, without the need to taking out this dowel pin, the core of dowel pin can being taken out and carry out Endodontic retreatment, overcoming because getting the risk and unnecessary expense that stake brings, and can increase work efficiency,, the side avoiding root canal pile to bring is worn, odontoclasis equivalent risk, reduces psychological impact and physiological effect that unnecessary process brings to patient, alleviate patient to seek medical advice expense, improve the work efficiency of doctor.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described, but this utility model is not limited to following examples.
Embodiment 1
Described have core zirconium oxide root canal pile ideograph to see Figure 1A, Figure 1B, Fig. 1 C, and integrated oxidation zirconium body (1) is truncated cone structure, and truncated cone structure inner core (2) can be filled with gutta-percha.Within having the external diameter of core zirconium oxide root canal pile to can be controlled in 1/3rd of root of the tooth root footpath, the tapering of Ying Yugen pipe is consistent; The wall thickness of zirconium oxide root canal pile can by with 0.01 millimeter-0.5 millimeter of sharp direction bladed, 0.2 millimeter-0.5 millimeter, hat side; Length in root pipe should be greater than the length of crown moieties, and should be greater than root of the tooth in bone total length 1/2nd; The tip of a root of the tip of a root direction distance tooth of root canal pile should not be less than 4 millimeters.Zirconium oxide root canal pile nail outer surface can in coarse, thread-like structure.
This utility model only need can take out the core of core zirconium oxide root canal pile with the root canal therapy device of routine when there is tip of a root pathological changes, get through root pipe, row root pipe in treatment, see Fig. 4.
Traditional root canal pile and Therapeutic mode are shown in Fig. 2 and Fig. 3.Need the worn root canal piles such as dental high-speed car pin be used when there is tip of a root pathological changes, or prize stake from the surrounding of stake, get through root pipe, row root pipe in treatment.
