Description of the Invention: [Technical Field of the Invention] The present invention relates to a carrier for filling a root canal, and a method for producing a root canal filling using the carrier. [Prior Art] In root canal treatment of teeth, it is necessary to close the outer opening (P_ls of Exit) of the root canal system with a filling to prevent the endodontic root canal from being infected by bacteria or causing lesions in the tissues surrounding the teeth. At present, the filling material for filling the root canal is mainly Guajia (GuUa·percha)' can be roughly divided into two ways of use: 1. Lateral squeezing and filling: firstly a one-male rubber main cone (Main c〇 Ne) After coating the root canal sealant (sealer), insert the built-in working length of the root canal into the root canal, and then insert a root canal into the lateral cannula with a squeezer; remove the squeezed needle and then gradually Inserting a plurality of sub-Malay plastic needles, each inserting a pair of Malay plastic needles, that is, inserting the needles for lateral extrusion; repeating the steps of inserting the sub-Malay gel needles several times to heat The device removes the Malay needle beyond the opening of the root canal, and then fills the remaining Malay needle in the pulp chamber vertically with a Plugmer (Plugger) to complete the root canal filling step. 2. Vertical flooding filling: using a Malay plastic needle that is sized after the root canal is shaped, it is coated with a root canal sealant and placed in the root canal. The Malay plastic needle is used in the root canal by a tip heater. (T〇uch Heater) heating and softening 'after removing the excess mala gel, applying the vertical force to the apex with the squeezer' to squeeze the Malay and the root canal sealant tightly into the 201010674 root canal system Inside, to close all external openings of the root canal system, the three-dimensional space is filled with dense filling. The first method of use is to directly fill the root canal with a plurality of shaped and solidified male rubber needles, and the use technique is relatively simple, and it is not necessary to use complicated and expensive instruments or equipment to assist the implementation, which is currently popular. How to use it. However, the procedure is complicated and takes a long time because the steps of placing the Malay needle and pressing the needle laterally are repeated. The first method of use is to use a size that is comparable to the modified root canal.
