A root canal filling instrument

Abstract

The invention discloses a novel root canal filling instrument which comprises a body for holding. A detachable heat carrying component and a vertical pressurizing component are arranged at two ends ofthe body respectively, and a control component for controlling working state of the heat carrying component is arranged on the body. The novel root canal filling instrument is convenient to operate,allows an operator to flexibly convert between heating and pressurizing and is convenient for clinical use, and instrument switching time is saved. The invention further provides a root canal fillingmethod. A mixing filling method is utilized, and the instrument is controllable in filling depth, free of excessive filling, little in damage caused to periodontium, low in requirements on root canalmaking, capable of quickly and effectively filling root canals and quite high in generalizability.

Description

technical field [0001] The invention relates to the field of medicine, further relates to the field of dental surgery, in particular to a root canal filling instrument. Background technique [0002] At present, gutta-percha is still the main material for root canal filling. The main filling methods are cold gutta-percha lateral pressure filling method, hot gutta-percha vertical pressure filling method and single-cusp filling method. The three methods have their own advantages and disadvantages: cold tooth gum The advantage of the lateral pressure filling method with glue is that the filling depth is accurate and controllable, but the disadvantage is that the filling in the middle and upper part of the root canal is not dense and uneven, and it takes a long time; the advantage of the vertical pressure filling method with hot gutta-percha is that the root canal filling is dense and uniform, and heating Flowing gutta-percha is good for filling irregular root canals. The first d...

[0002] At present, gutta-percha is still the main material for root canal filling. The main filling methods are cold gutta-percha lateral pressure filling method, hot gutta-percha vertical pressure filling method and single-cusp filling method. The three methods have their own advantages and disadvantages: cold tooth gum The advantage of the lateral pressure filling method with glue is that the filling depth is accurate and controllable, but the disadvantage is that the filling in the middle and upper part of the root canal is not dense and uneven, and it takes a long time; the advantage of the vertical pressure filling method with hot gutta-percha is that the root canal filling is dense and uniform, and heating Flowing gutta-percha is good for filling irregular root canals. The first disadvantage is that the filling depth of the root canal is not easy to control and it is easy to overfill, and the second is that the high temperature is easy to damage the periodontal tissue. The production requirements of the tube are relatively high, and the shape of the root canal is required to be consistent with the size of the gutta-percha tip

[0003] In addition, taking the hot gutta-percha vertical pressure filling method as an example, the doctor needs to switch between operating the pressure equipment and the heating equipment during the existing operation, which is very inconvenient to operate; moreover, most of the existing heating equipment adopts electric heating Equipment, on the one hand, there is a risk of scalding the patient's oral mucosa, which leads to great psychological pressure for the patient; on the other hand, the sensitivity of this type of electric heating equipment is limited, which is very easy to cause uneven heating of the gutta-percha, and may even damage the patient's root canal
