[0006] In addition, in the article titled "Fatigue testing of a NiTi rotary instrument. Part 1: strain–liferelationship" published in International Endodontic Journal, Volume 40, pages 612-618 in 2007, various cross-sections and processing grooves are also mentioned. Grooves cause differences in fatigue life of NiTi devices
Water may cause crack propagation cracks in the material, reducing cyclic fatigue life

Embodiment 1

[0033] Such as figure 1 As shown, the root canal preparation device of this embodiment includes a nickel-titanium preparation system and a flushing system. The nickel-titanium preparation system includes a nickel-titanium file 1, a mobile phone head 2, a mobile phone body 3, an electric motor 4, and a power controller 5. The flushing system includes: a conduit 6 , a conduit fixing device 7 , a liquid pump 8 , and a liquid pump controller 9 .

[0034] As shown in the figure, the nickel-titanium file 1 is installed under the head 2 of the mobile phone. The mobile phone head 2 is used to hold the nickel-titanium file, and the mobile phone body 3 is the part held by the hand when preparing the root canal. During operation, the direction of the drill needle and the lifting force can be controlled. The electric motor 4 is used to generate and transmit power, and a transmission device can also be used for mechanical transmission connection between the electric motor 4 and the nickel...

Embodiment 2

[0047] In this embodiment, the root canal preparation equipment used is basically the same as in Embodiment 1, except that in this embodiment, a liquid temperature control device is added, which is installed on the liquid pump or the liquid pump controller to control the liquid temperature. The liquid pumped by the pump is temperature controlled. Then, the inventors used different flushing water temperatures for root canal preparation.

[0048] The preliminary results are as follows:

[0049] The comparison of each parameter when table 2 three kinds of temperatures ( n=60)

[0050]

[0051] Note: **P<0.01.

[0052] Table 3 Comparison of the number and proportion of root canal side penetration at three temperatures

[0053]

[0054] The applicant found that the normal temperature flushing group can prepare more root canals and prolong the service life of the nickel-titanium files; when the high-temperature flushing, the nickel-titanium files prepare the most root can...

Embodiment 3

[0056] In this embodiment, a root canal preparation device similar to that of Embodiment 1 is used, but different from Embodiment 1, this embodiment adopts a different flushing control method.

[0057] Specifically, in this embodiment, a root canal preparation device similar to that of Embodiment 1 is used, but different from Embodiment 1, this embodiment adds a flow control device to control the temperature at 23°C, and adopts different Flush flow for root canal preparation. The minimum flow rate is 220ml / min, and the maximum flow rate is 270ml / min.

[0058] The preliminary results are as follows:

[0059] The comparison of each parameter when table 4 two groups of different flows ( n=40)

[0060]

[0061] Note: *P<0.05, **P<0.01.

[0062] Table 5 Comparison of the number and proportion of root canal side penetration at two flow rates

[0063]

[0064] The applicant found that when the root canal was prepared, flushing with a small flow rate was more likely to cau...

Abstract

The invention discloses nickel-titanium file root canal preparation equipment. The root canal preparation equipment comprises a nickel-titanium file preparation system and a flushing system, wherein the nickel-titanium file preparation system comprises a nickel-titanium file (1), a mobile phone head (2), a mobile phone body (3), an electric motor (4) and a power controller; and the flushing system comprises a conduit (6), a conduit fixing device (7), a liquid pump (8) and a liquid pump controller (9). The inventor of the invention discovers that the existing theoretical research on the root canal preparation misleads the root canal preparation method in practice to cause the fact that the existing nickel-titanium root canal preparation adopts a dry drilling mode, but through practice test, the inventor discovers that the service life of the nickel-titanium file can be greatly prolonged if water flow is added to flush in the root canal preparation process, so the inventor prepares the corresponding root canal preparation equipment.

Description

technical field [0001] The invention relates to an oral cavity treatment device, in particular to a nickel-titanium file root canal preparation device for cleaning tooth root canals. Background technique [0002] At present, there are many kinds of nickel-titanium systems and devices for machine use, and they are increasingly used in the domestic market. However, the use of any system of nickel-titanium devices for machine use has the potential risk of breaking the device. There is no clear research showing the maximum number of uses of nickel-titanium devices. Although most foreign endodontic doctors and manufacturers recommend one-time use of machine-use nickel-titanium products, the current oral medical environment in my country cannot meet this standard for the time being. [0003] At present, nickel-titanium files are generally easy to break after being used several times (such as Peng Bin and other studies have shown that the S1 of the ProTaper file can prepare 25 ante...
