Description
Technical Field
The utility model relates to a dental root canal treatment device, in particular to a root canal plug tip and a device for filling a root canal.
Background
Root canal therapy is the main treatment means for the pathological changes of tooth pulp and tooth root.
The dental root canal therapy process comprises the following steps: the method comprises the steps of tooth pulp opening, pulp removing, tooth length measuring, root canal preparation, disinfection and finally, dipping a gutta-percha point made of solid materials into a fluid medicament to tightly fill each root canal.
The gutta-percha point mainly comprises gutta-percha, zinc oxide, barium sulfate, and pigments of various colors such as ultramarine, chromium oxide, dye yellow, etc. Wherein barium sulfate, chromium oxide, yellow dye and the like have potential toxicity to human bodies.
Because the gutta-percha point is soft in texture, poor in specification precision and quite inconvenient in filling operation, the conditions of overcharge or underfill of the gutta-percha point and the like are not rare clinically. The underfill can cause the failure of root canal therapy, and the overcharge can cause the gutta-percha point to exceed the apical foramen of the tooth root and then contact the human body for a long time, so that certain potential harm exists when the gutta-percha point contacts blood for a long time.
Therefore, how to seek a filling device for root canal therapy which is safer, more convenient and faster in clinical operation and more stable and reliable in treatment effect becomes a problem which needs to be solved at present.

Compared with the prior art, the utility model has the following beneficial effects:
1. high density and high quality root canal filling.
This novel root canal section of root canal stopper tip comprises screw thread portion, blade two parts, perhaps the root canal section comprises blade, and during the root canal was filled, the root canal stopper tip was rotatory the propulsion in the root canal root chamber of tooth rather than the tapering is identical, can produce certain pressure and evenly ground compaction in root canal tip section root canal with more medicament layering, and the root canal section that forms the high density is sealed to realize high-quality root canal and fill.
2. Greatly reduces the operation difficulty of doctors and shortens the operation time.
Compare gutta-percha point texture soft, specification size precision is poor, meet the wet easy bending deformation that hinders, the root canal filling degree of difficulty is big, consuming time and difficultly scheduling problem, the influence of adverse factor such as the root canal stenosis of tooth, resistance and the intraductal medicament of root of this titanium root canal stopper point can be neglected, the root canal filling of one step to the position formula can be exerted radial force after filling to target in place a little and can be cut, and is simple high-efficient, greatly reduces doctor's the operation degree of difficulty, shortens operating time.
3. Excellent safety.
Because of excellent biocompatibility and affinity of the titanium material, the root canal plug tip of the titanium material is the only existing root filling device which is allowed to exceed the tooth apical pore, and the excessive titanium tip can induce the growth of bone cells to form the compact bone plate in the apical area.
The titanium root canal plug tip avoids the potential damage of toxic components such as barium sulfate, chromium oxide, yellow dye and the like contained in the traditional gutta-percha tip (composed of materials such as resin glue, zinc oxide, metal salt, pigments with various colors and the like) to human bodies.
4. Greatly improves the fracture resistance of the affected teeth and prolongs the service life of the affected teeth.
When the titanium material root canal tip is used for the root canal preparation in the early stage, the preparation is mostly carried out only by preparing a 04 taper 20 (the root tip diameter is 0.20mm), and the unnecessary preparation cutting damage amount to the healthy tooth root canal is effectively reduced.
This titanium material root canal stopper point integration runs through the whole tooth body from root apex to dental crown cave hole, can replace root canal nail or fibre stake, need not secondary beat root canal nail or fibre stake, has reduced the cutting preparation of the unnecessary injury nature of secondary to healthy tooth body tissue when filling back beat root canal stake, has improved the anti rupture ability of suffering from the tooth body.
1-3 titanium metals are added from the root tip to the dental crown in the affected tooth body, the overall strength is obviously improved, the anti-fracture capability of the affected tooth body is greatly superior to that of the traditional secondary root canal post driving method, and the service life of the affected tooth is prolonged.
5. The root canal plug tip is made of titanium material and has conductivity, so that the root canal plug tip can be directly and electrically connected with an electronic root length measuring instrument, a root canal plug tip thread groove and part of horizontal blade grooves are filled with medicaments and plugged into a root canal, the length of the root canal is measured while rotating, and accurate root canal filling to the maximum degree is realized.
6. The titanium root canal apex brings a brand new root canal treatment idea.
The traditional root canal therapy method is the filling of gutta-percha points and calcium hydroxide iodoform paste, because the calcium hydroxide paste has the characteristics of volume shrinkage and water solubility after solidification, in order to ensure good root tip sealing, the traditional therapy idea is mainly to use the gutta-percha points and the paste as auxiliary, a small amount of paste and as much gutta-percha points as possible are filled in a pressurizing mode, and the gutta-percha points are not allowed to exceed the root tip holes (the toxic and side effects of chemical apicitis can be formed when the gutta-percha points exceed the root tip holes), the gutta-percha points and the root canals are mainly sealed by a physical method, and the traditional root canal therapy method is a physical sealing therapy method.
The new concept of the root canal therapy of the utility model is a biological sealing therapy, because the titanium metal material has excellent biocompatibility in nature, the root canal tip of the titanium material can be allowed to exceed the apical pore and can induce the growth of bone cells, the root canal tip of the titanium material and the biological ceramic paste (such as calcium phosphate, hydroxyapatite and the like) are filled, and after a period of time, the bone cells can be induced to grow into the apical area to form good biological sealing of the apical area. Therefore, the brand-new concept of the biological closed treatment method for the affected tooth root tip brought by the root canal apex of the titanium material can bring more long-term, more stable and safer beneficial treatment effects
